  3. 3. 2012 FTTH Conference & Expo: The Future Is Now – Dallas, TexasAbstractMost broadband access networks are still relying on either twisted pair copper wires(xDSL) or coaxial cables (HFC) which are not meeting the ever increasing bandwidthdemands. Recent adoption of Fiber-To-The-X (FTTx) technologies by Telecom andCable operators demonstrate delivering high-speed ultra-fast broadband to meet therequirement of next-generation multi-play video applications. Optical fiber networks areoffering much higher bandwidths than the old technologies by supporting numerousservices simultaneously in the last-mile. The FTTx networks are classified in manyvarieties depending on the last-mile termination point and reach of the Fiber-to-theHome (FTTh), Premises (FTTp), Cabinet (FTTc) and Node (FTTn). FTTx containsdifferent technologies including Passive Optical Network (PON), Ethernet Point-To-Pointand hybrid models of centralized and distributed PONs.On the other hand, the wireless market is quickly evolving with the introduction of theLong Term Evolution (LTE) technology. LTE and 4G networks, combining with FTTx, arerapidly changing the game show enabling operators to meet traffic demands. Thecapability of extending the Fiber-To-The-Cell Towers (FTTct) within access networks, inthe form of FTTct by leveraging the Gigabit & WDM-PON based resilient architectures,are filling the higher bandwidth rate gaps for mobile based applications and seamlessmultimedia experience. All the evaluating technical and challenging financial trends areputting a lot of pressure on telecom operators to choose the right business model. Theoperator’s main challenge is whether to go for Greenfield deployments, utilize theexisting infrastructure in Brownfields or go with complete refurbishment networks inMetro cities and suburban areas.To address the challenges mentioned above as well as strategize the next-generationFTTx business models by keeping the view of increasing demand for mobile broadbandusers, this paper will discuss both Point-to-Point and Point-to-Multipoint (PON)architectures; in addition to, explaining how to integrate the LTE and FTTx by detailingthe methodological approaches. The key highlight of this paper is to provide innovativebusiness models by using the proven spatial technologies. Two case studies will bediscussed both FTTp and LTE by illustrating the flexibility and scalability to support bothresidential and business users. A complete range of parameters will be taken intoaccount including strategic, demographical data, regulatory requirements, budgets forpricing, high-level and detailed engineering for resilient network architectures,deployment methods, testing and integration with Operational Support Systems. Aparticular focus is given to non-price considerations, which come to the forefront, due tothe unique strategic and technological characteristics of optical fiber in the last-mile. Thispresentation will identify a superlative FTTx business model to meet the bandwidthdemands of fixed and mobile broadband applications.

  4. 4. 2012 FTTH Conference & Expo: The Future Is Now – Dallas, TexasFull PaperIntroductionThe demand for broadband is increasing rapidly due to the end-user requirementschanging from triple-play to quad-play and then quad-play to multi-play. The bandwidthconsumption is enormous to access these kinds of services; therefore, the informationtransport must be based on optical fiber technology in order to handle the traffic volume.Telco operators are deploying fiber based networks especially in access networkscapable in providing the promised services as well as meeting the demand of NextGeneration Networks (NGN). The last mile fiber networks come in many varietiesdepending on the termination point: Premise (FTTp), Home (FTTh), Curb / Cabinet(FTTc), Node (FTTn) or Cell Site (FTTcs). For simplicity, most people have begun torefer to the network as FTTx, in which x stands for the termination point. Over the pastdecade many Telco operators began to replace their copper wire lines with a fiber opticnetwork to meet their bandwidth requirements. With increasing demand for moresophisticated data services, Telco’s are gradually moving to fiber backhaul LTEnetworks. An advantage of LTE networks is that it provides nomadic services to the enduser wherever, whenever and however.Long Term Evolution (LTE) / 4GIntroduction of LTE / 4G networks are changing the way of mobile user’s experience andevolving to offer high-speed mobile applications including real-time digital videostreaming and high-definition multimedia applications over Smartphones, iPADs andnotebooks. LTE technologies are presenting opportunities to increase revenues;however, require increased network investments in the backhaul to handle the trafficexplosion. The additional requirement of 4G bandwidths is required to build high-capacity mobile backhaul/backbone networks including the upgrade of existingtraditional networks such as TDM, Frame Relay and ATM circuits. Also, 4G networkscreated the necessity for the operators to extend their backhaul from cell site to cell siteand high capacity multiple cell sites to Mobile Switch Office (MSO) to utilize advancedtechnology of Carrier Ethernet (CE) capability enabling bandwidth demands to be met. Ithas been identified that, optical fiber based backhaul networks with CE technology arecapable of serving millions of mobile subscribers which provides common, reliable andsecure transport architecture for current and future needs. Ethernet, over FTTx withmultiple options of active fiber direct run to cell sites as well as Gigabit based PONfibers, are gaining more technology advantages. The trend now involves operatorschoosing IP/Ethernet backhaul as their main technologies to cut down their cost andeffectively scale their transport networks in support of LTE. Mobile networks are evolvingby leveraging the FTTx capabilities in the last mile to enable LTE / 4G services.

  5. 5. 2012 FTTH Conference & Expo: The Future Is Now – Dallas, TexasCarrier Ethernet (CE)CE defines the use of Ethernet frames as a transport facility, enabling such frames totransport IP packets or even Asynchronous Transfer Mode (ATM) cells. Because Ethernet is scalable, in particular, the 10-G Ethernet is more capable to scale the higher data rates. Fiber backhaul Ethernet is becoming the main source, with advantages of packet transmission, in building the efficient and easily managed Metro Ethernet Networks which are supporting the huge traffic of LTE / 4G networks. In this application, the backhaultransport provider can take advantage of legacy wire equipment with integrated Ethernetswitching and Operations, Administration and Management (OAM) capabilities for bothEthernet and T1/E1 service operators.CE has become a powerful tool for service providers to employ Metro Ethernetconnectivity, providing reliable transport that is cost effective and operationally efficient.CE provides a service diagnostic which is well known and a relatively simple solution formobile backhaul. Together, CE and Ethernet service products enable service providersto extract new levels ofefficiency from their mobileservice network. CE, as aservice provider’s transportfacility and an Ethernet service,can be based upon virtuallyany transport technology suchas Ethernet over SONET,IP/MPLS and so on. A specific CE service type that actually represents a topology canalso be transported as a native Ethernet or carried by another transport facility.FTTx for Mobile Backhaul Ethernet Networks (MBEN)Fiber backhaul for mobile towers with the capability of CE is a dominant cost-effectiveand high capacity service which offloads the high-data traffic from base stations to Mobile Switching Center (MSCs). Wireless carriers are turning to optical backhaul strategies especially in access networks with the capability of FTTx for simplified high-capacity infrastructure that brings significant operational value. One of the leading technologies for achieving advantages in LTEnetwork is packet-optical convergence by mixing the Dense Wavelength DivisionMultiplexing (DWDM) / Optical Transport Networking (OTN) alongside Reconfigurable Strategizing Future-Proof FTTH Business Models – Innovation Approach / Kiran Solipuram & Kevin Challen / Infotech Enterprises Page 5 of 15
  6. 6. 2012 FTTH Conference & Expo: The Future Is Now – Dallas, TexasOptical Add-drop Multiplexer (ROADM). These capabilities enable the LTE operators tomigrate from traditional SONET / SDH to the next generation carrier Ethernet under asingle platform, and managed by a single, multi-layered, network management system.This integration allows a carrier or service provider to seamlessly provide any service, toany customer, at varying capacity - all under a single platform and infrastructure.Some carriers are already seeing revenue ramp up from these efforts, while some arejust signing long-term contracts for future return. Keeping this in mind, the mobilebackhaul networks must be planned and designed correctly in order to provide reliable,future-proof and cost-effective high capacity transport.FTTx Deployment Challenges for LTEWhen deploying an LTE architecture orupgrading the legacy TDM mobile backhaulby extending FTTx networks, the telecomoperators have many things to consider whichinclude the existing outside plant, architecturalplans, network locations, technologycompatibility, cost of deploying the network,subscriber density and return on investment.Various technologies including Active StarEthernet (ASE), Metro Ethernet (MEN) andGigabit Passive Optical Network (GPON),which are extended to cell towers, are theconsiderable choices for LTE / 4G networks.Another major impact on carrier networks,worldwide, is the continuing needed to meetregulatory interconnect and unbundling pointsfor fair access by competitive providers.While gaining the advantages from LTE with the mix of FTTx technologies, Telcooperators have to consider eliminating the challenges below:  CE technology is exposing a major challenge in mobile backhaul as much infrastructure around the world was deployed in legacy leased lines and Time Division Multiplexing (TDM) architecture. Now, the operators have to either make smooth upgrades while serving the customers or swap with CE infrastructure.  Whether to go for Greenfield deployments utilize the existing infrastructure in Brownfields or go with complete refurbishment networks in Metro cities and suburban areas.  One of the most challenging issues is how to handle the rapid transition to an all- packet NGN network while maintaining the existing subscribers who are on legacy TDM and E1 / T1 circuits.  Telecom service providers, operations and network support systems and processes, solution providers and contractors will have to work together in a coordinated way to deliver content smoothly and symmetrically while extending the fiber based networks (FTTx) to the 4G networks which looks like an impossible task.

  7. 7. 2012 FTTH Conference & Expo: The Future Is Now – Dallas, Texas  Extending the FTTx networks to the cell site switches along with utilizing the Gigabit PON capabilities while maintaining the need for increased capacity, scalability and reliability.  A key question is how to structure the network in an optimal way to gain from the advantages of using the latest technologies and innovating optical communications.FTTx Deployment Scenarios for LTE NetworksAlthough fiber based Ethernet over SONET/SDH (EoS) are still considerable choices,there are two main fiber backhaul technologies that are inspiring the LTE networks forlow cost deployments and greater revenues which are ASE and GPONs. This paperfocuses on the ASE and GPON technologies, its deployment scenarios and optimizationprocess for network planning and design by leveraging the spatial based systems andengineering tools.Active EthernetActive Ethernet for LTE is the evaluating architecture in where the fiber plays a majorrole in forming the network to provide the CE capabilities in the backhaul networks. In an active Ethernet architecture, multiple LTE towers share dedicated fibers to form the carrier capabilities from the Optical Transport Switch (OTS). Environmentally hardened optical Ethernet electronics, switches or Optical Transport Carriers (OTC) are installed at the remote node to provide fiber access aggregation. The remote node can be shared between multiple LTE towersor simply can be terminated at other switching locations which provides full bi-directionaldata traffic. This architecture is most suitable for high-dense areas where more LTEtowers are required to be deployed. Active Ethernet reduces the amount of fiberdeployed while lowering costs through the sharing of fiber in aggregation and corenetworks. It is a readily accepted architecture which upgrades the traditional mobiletowers to LTE towers and increase capacity to handle the traffic. It also offers thebenefits of the standard optical Ethernet technology which presents much simplernetwork topologies and supports a wide range of LTE solutions. Most importantly, itprovides broad flexibility for future growth. Active fiber deployments are an excellentchoice for service providers when the customer is in an on-net building in a densemetropolitan area or in a new infrastructure build-out.Gigabit Passive Optical Network (GPON)GPON is currently one of the fastest access technologies to attract market interest.GPON’s popularity is due to several factors including the support for wide range of Strategizing Future-Proof FTTH Business Models – Innovation Approach / Kiran Solipuram & Kevin Challen / Infotech Enterprises Page 7 of 15
  8. 8. 2012 FTTH Conference & Expo: The Future Is Now – Dallas, Texasprotocols, applications and services. GPON is flexible for various network architecturedeployments, for example, in combination with Very-high speed Digital Subscriber Line 2(VDSL2, with fiber to the curb, FTTC), as residential access (fiber to the home, FTTH) ora carrier Ethernet based LTE network. A GPON solution is an integral part of a fullservice broadband architecture,which is designed to meet the needsof fixed–mobile convergence andNGN across residential andenterprise service offerings. TheGPON evolution and standardizationoffers many new capabilities that willsupport broadband access networksand services for the future. GPONsupports 2.5 Gbps downstream and1.25 upstream for each channelalongside supporting the LTE services. Many operators and vendors in the industry viewWavelength Division Multiplexed PON (WDM-PON) as the ultimate long-term PONtechnology, where a PON topology supports a logical point-to-point network which ismore beneficial for LTE services. WDM-PON offers an alternative to the GPON time-shared transmission scheme in which each Optical Network Terminal (ONT) transmitsand receives on a specific wavelength.GPON is flexible and economical solution with carrier Ethernet extended capability whichcan be deployed for variety of LTE architectures with various network scenarios whichare described below.  Scenario #1 – Centralized PON for LTE Services: This scenario describes the best deployment method for GPON extending to the LTE towers. This planning scenario is most economical for connecting the LTE towers with fiber backhaul in Greenfield situations. The carrier Ethernet gets extended to the designated LTE tower with the optical fiber cable from the nearest L2 Metro OTN Switch. An Optical Line Terminal (OLT) can be installed at the LTE tower which is connected from the backhaul OTN switch. Further, the OLT can connect to the centralized optical splitter which eliminates the need of power suppliers. The split ratio can be 1:16, 1:32 or two 1:16 based on the operator’s requirement. This centralized L1 splitter can be connected directly to SDUs and (Multi-dwelling Units) MDUs. In turn, L2 splitters can be installed near each MDU to simplify further cable distribution in MDUs. Figure 1: Centralized GPON Scenario Strategizing Future-Proof FTTH Business Models – Innovation Approach / Kiran Solipuram & Kevin Challen / Infotech Enterprises Page 8 of 15
  9. 9. 2012 FTTH Conference & Expo: The Future Is Now – Dallas, Texas The LTE tower can be connected with dedicated PON ports, as per the bandwidth requirements, which can be upgraded. The entire carrier Ethernet services can be configured by converting the optical signals to the Ethernet signals enabling the LTE services for a particular LTE tower. This deployment methodology is easy and good for high-dense areas. On the other hand, the traditional T1/E1/TDM services can be upgraded without adding the additional equipment costs with this architecture. This architecture saves the fiber deployment cost by reducing the fiber split which can decrease sharing and free up bandwidth for high-bandwidth users and base LTE nodes. Scenario #2 – Distributed PON for LTE Services: This deployment scenario is quite similar to scenario # 1 except the last-mile network deployment methodologies. This is a distributed GPON from the LTE node which helps the longer distance premises including MDUs. For a better understanding, all the last mile connections are shown with MDUs in the diagram below. This scenario uses the mixed architectures of P2P and P2MPs with the carrier Ethernet capabilities. OLT of the LTE node can be connected to a L1 optical splitter with dedicated fibers in turn; L2 optical splitters can be terminated at the L1 splitter ports. Bandwidth can be managed either at the LTE node or L2 metro OTN switch. Figure 2: Distributed GPON Scenario Similar to scenario # 1, this architecture is capable of delivering the entire carrier Ethernet services to the LTE subscribers over the GPON backhaul network. This is one of the economical architecture for connecting the larger distance MDUs. Assuming a high video service take-rate and a worst-case scenario where every residential subscriber is simultaneously streaming multiple and unique high- definition video channels at about 10 Mb/s each. A rough calculation shows that about half of the downstream bandwidth is still available for multiple LTE base stations on the same PON. In the future, next-generation 10G PON interfaces will be provided, even on fatter pipes, with the same fiber network by using a wavelength overlay technique. Consequently, from a bandwidth perspective, this scenario represents a strategic long-term solution for 3G to LTE / 4G migration.

  10. 10. 2012 FTTH Conference & Expo: The Future Is Now – Dallas, TexasTDM, E1/T1 Migrations to EthernetThe key objective of the legacy migration to IP/Ethernet is to meet the new services andhandle the huge mobile traffic over LTE nodes. The migration solution should meet therequirements of geographical conditions, regulatory environments and competitivemarket dynamics. For example, North American backhauls are dominated by leasedlines (T1) which are wired solutions while the Asia Pacific (APAC) region follows to buildthe new microwave towers in Brownfield situations. In addition to the above two GPONbased LTE scenarios, let’s see how IP/Ethernet supports the migration of legacy TDM,E1 / T1 mobile backhauls.Migration Scenario # 1This scenario recommends introducing IP/Ethernet enabled devices at the base stationswhich will enable to transport all the traffic onto a packet switched network. Thus,Ethernet can support huge IP traffic (IP packet frames) by building the capabilities ofmulticasting for next generation video services. This scenario brings huge technicalbenefits by multiplexing various services over an IP network while reducing theoperational costs. All Pseudo-Wire technologies are best suitable for this migrationscenario.Migration Scenario # 2This scenario recommends introducing the fiber media in mobile backhauls along withupgrading the end-to-end devices with IP/Ethernet. This migration scenario involvesextra efforts while, migrating the entire backhaul and sometimes, the existing servicesmay get disturbed. All these things require special planning and migration toolsalongside unique approach. This scenario enables the full multicast services andenables to provide all the LTE services.Note: These scenarios may be detailed based on the specific needs going forward.FTTx – LTE Planning and Design CycleThe common planning and design cycles are not sufficient to deploy the networksmentioned above as the deployment challenges are unique while migrating thetraditional TDM, E1/T1 services or constructing a Greenfield LTE networks. Belowdescribes a unique approach to address the needs of LTE with a mix of FTTx (GPON)network deployments by using the geospatial based automated engineering tools. Thisdesign methodology, based on industry best practice, defines the end-to-end processesranging from collecting the geospatial information to network design and further networkoptimization which helps operators to reduce the CapEx and OpEx. 7 Steps for Successful FTTx – LTE Deployments Figure 3: Planning & Design Cycle Strategizing Future-Proof FTTH Business Models – Innovation Approach / Kiran Solipuram & Kevin Challen / Infotech Enterprises Page 10 of 15
  11. 11. 2012 FTTH Conference & Expo: The Future Is Now – Dallas, TexasReturn on Investment (ROI) AnalysisROI analysis is based on the present demand and future forecast of the geographicaland network coverage. The differentiation and classification of customers as business or residential, high and low dense areas including MDU, forms the part of the analysis. All these analysis aspects help the operators to understand the network construction areas and the cost for building the network. The identification of potential revenue generating areas is also critical for business investment. This analysis process leverages key GIS functionalities, intelligent demographic data combined with analysis of the customer’s physical network to quickly identify key locations for the focus of LTE nodes deployment. This analysis provides a complete overview of theareas to build, various feasible backhaul route options to reach the LTE towers fromMCNs / OTN switches and the services to offer which will help the operator to makestrategic decisions.High-Level Design (HLD)The HLD involves the evaluation of economicdevelopment, identification of the existingtelecommunications facilities, forecasting futurecustomer demand and building the network based onthe RoI forecast. In addition, the HLD process willhandle the shortages of the existing network, TDM,E1/T1 migration requirements and be able to servethe present and future customers. The HLD providesspatial based route mapping as well as physical andtechnical constraints. This process targets thenetwork planning based on the ROI deliveries andreducing cost of network migration/deployment, byplanning the most optimized network to meet customer requirements.GIS study (i.e. existing trenches, ducts, cables, manholes, termination equipment andlocations) are first analyzed; thereafter, the new ducts and cables will be planned. Whileplanning the network, aspects such as customer demands, technologies andarchitectures and topology are also considered. The HLD process includes estimatingthe size of the fiber that needs to be placed from the central office to the LTE node aswell as placing optical terminals and structures. The creation of detailed permit drawingsis an integral part of this HLD process.A key activity in this HDL process is to cluster the potential areas, grouping the feasibleeNodeB locations and segregating them into various OTN areas. Below are the basicparameters considered for this process: Strategizing Future-Proof FTTH Business Models – Innovation Approach / Kiran Solipuram & Kevin Challen / Infotech Enterprises Page 11 of 15
  12. 12. 2012 FTTH Conference & Expo: The Future Is Now – Dallas, Texas  Nearest and feasible route for each LTE tower from nearest OTN switch  Maximum distance permissible for eNodeB from nearest OTN switch  IP/Ethernet equipment termination locations and its connectivity  Natural obstructions / boundaries such as rivers, highways, railway tracks, etc.  Minimum road crossings  Length of the fiber / trenches  Feasibility to utilize the existing ducts / conduitsField SurveyThis field survey will be performed with referenceto the HLD documents. The field survey will bebroadly categorized into above ground andunderground data collection. As the namesuggests, the above ground data collection willcover all above ground assets such as nodelocations, buildings, poles, obstructions and fibercable routes, and the underground datacollection will cover all underground assets suchas optical fiber cables, ducts and all utilities. Fieldsurvey can be performed many ways with thehelp of advanced tools such as GPS, mobiletechnology, radio frequency locating equipment,etc. The following activities will be performedduring the physical site survey:  Field walkout to the particular site to identify and confirm the node/building locations  Collection of latitudes and longitudes of the node/building locations  Fiber tapping location and route to be connected from the main metro rings  Entry routes and termination points of each node building location  IP/Ethernet equipment locations / termination points  Estimation of fiber size that needs to be placed  Backhaul protection ring paths and routes to nodes  Details of cable loops and sufficient lengths  Possible road/railway crossings  Type of ground such as gravel or asphalt for construction Strategizing Future-Proof FTTH Business Models – Innovation Approach / Kiran Solipuram & Kevin Challen / Infotech Enterprises Page 12 of 15
  13. 13. 2012 FTTH Conference & Expo: The Future Is Now – Dallas, Texas  Updating the new routs/buildings/any new GIS data with the latitudes and longitudes onto the GIS system  Traffic density of roads, depending on different timings (peak and low)  Presence of utilities like gas, electrical, telecom pipelines  Limitation of local permissible possibilities  Construction types including boring, trenching drilling, etc.Plan ApprovalsSubsequent to field survey reports updating in the HLD drawings, all the consolidateddrawings and reports will be sent to the operator for approvals. The operators can makethe decision based on the investment plans and ROI.Low-Level Design (LLD) All approved HLD drawings and CAD based tentative routes will become inputs for low-level designs. The LLD process starts with placing all the elements onto the GIS and CAD system as per the HLD document. The design activity includes placing of duct structures, creation of duct structure internals, design of trench routes in continuation to underground routes,optical fiber cable placement with reference to the duct structures, placement of splices,connections and equipment, and end-to-end termination points. This is the most efficientand economical process as this phase isperformed with a lot of automatedengineering tools. Further, a LLD deliverypack set will be created which includesdetailed material requirement sheets(BoM/BoQ), splice sheets, schematicdrawings, SLDs, road/railway crossingdetailed drawings and constructiondrawings.Field Build OutOperator’s engineering team takes the completed designs and rollouts the network asper the design instructions and work schedules. This process also includes providing alean support to the field crew to ensure the smooth network rollout on the fields. Adedicated team will be assigned to this activity. The field team may find some changesas per the field conditions which will be recorded onto the LLD drawings with hand-written marks and will be sent back to the design teams.As-Built RecordingSubsequent to the field work, the design team converts the field recorded informationinto a work order for the as-built stage. Further all the field changes will be analyzed andrecoded either on the same LLD drawings or a geospatial system. Citrix architecture willbe proposed for accessing the spatial and other supporting systems.

  14. 14. 2012 FTTH Conference & Expo: The Future Is Now – Dallas, Texas Figure 4: Infotech Online Setup for As-built RecordingConclusionFiber enabled backhauls for LTE coupled with third-generation (3G) and fourth-generation (4G) are becoming more famous for the operators due to the huge data trafficgrowth. For many operators, migration to high-speed packet access network on thesame mobile backhauls just doesn’t make business sense. Migration of legacy TDM, E1/ T1 circuits requires unique approaches as the general procedures are not sufficientwhich are non-effective. The upcoming LTE network requires effective design tools toensure to meet the demand of ever-increasing deployments. Ultimately, the currentmobile towers requires re-design and upcoming LTE nodes are in need of efficientnetwork planning to leverage the fiber enabled backhauls. The key for the success is tostrategize the future-proof business models by leveraging the optical fiber cablebackhauls. The high-capacity fiber enabled backhauls by leveraging the GPON /10GPON capabilities coupled with carrier Ethernet is always a wise choice for theoperators. That is the place where our innovative spatial approaches are helping theoperators globally.Author Biography: Kiran Solipuram has 14 years of experience in planning, design, installation, construction, and operations of Telecom network infrastructure with various multinational Telecom operators.
