Current Building Construction for new K-12 Schools, Higher Educational facilities, and Hospitals require much more than an Ad-Hoc approach to technology design and this presentation provides some of the basic standards that should be followed.
M2FX FTTH Africa: Alternative FTTH TechniquesSimon Roberts
I was asked to give a presentation at the FTTH Africa conference in October demonstrating an alternative method to deliver large, scalable FTTH connections.
I focused on ADSS/Aerial solutions looking at the network topology right the way down to the last drop and preferred methods of installation.
I believe that ADSS offers significant deployment and ROI advantages when compared to traditional 'Cable in Duct', but as the presentation goes on to explain, this is really a toolbox effect.

Ausgrid is investing more than $1 billion in the Sydney CBD electricity network over five years to 2014. Ausgrid's Sydney CityGrid project involves constructing new substations, replacing and upgrading high-voltage cables and constructing a new tunnel to link into our existing network of CBD cable tunnels. These tunnels connect to form an 8 km ring under Sydney's CBD that interconnects Ausgrid's substations.
To provide a GRN P-25 coverage solution into these tunnels for Ausgrid's maintenance staff presented a challenge. Coverage is provided by utilising 'radio over fibre' repeater technology which rebroadcasts the NSW Government Radio Network from two dedicated base station sites located in two of Ausgrid's substations. Radiating cable, fixed to the ceiling of the tunnel, distributes the radio signals to the user in the tunnel, providing a method of communications deep underneath Sydney's CBD, where previously there was no way of communicating with the outside world.

The project manages to derive the range of operation of a user in interference based scenarios between Femtocells and Macrocells, in terms of Signal to Noise and Interference ratios. The simulation was carried out for both the uplink and the downlink scenario. It could be successfully concluded that the environment that the user is in plays an important part in performance evaluation of the user.

With the previous Master Format changes the industry has changed the following terms. MDF and IDF old AT&T terms The reason for changing the phrase telecommunications is its no longer just voice and data running over the low voltage cable infrastructure.
NOW LETS TALK ABOUT THE 3 MAIN ROOMS FOR TELECOMMUNICATION EQUIPMENT AND CABLING Local Area Network and Private Branch Exchange (PBX)
1. MER housed equipment that serves the entire organization or building. The equipment within the MER is very complex in nature.
THE ITR HOUSES EQUIPMENT THAT IS FLOOR SERVING ONLY
NOW LETS TALK ABOUT HOW INFO IS TRANSFERRED OVER THE FIBER. DATA TRANSFER RATE IS THE AMOUNT OF DATA THAT CAN TRAVEL FROM ONE POINT TO ANOTHER, ITS EXPRESSED IN BITS PER SECOND AND REFERS PRIMARILY TO THE CAPABILITY OF THE ELECTRONICS MEGA – MILLION GIGA - BILLION 40 Gbe IS AROUND THE CORNER WITH THESE SPEED INCREASES IT’S GOTTEN TO THE POINT THAT TECHNOLOGIES ARE REALLY PUSHING THE LIMITS OF THE FIBER OPTIC CABLE. NOTE – TECHNOLOGY USUALLY INCREASES 10X
Integrating data, email, fax, voice and video-conferencing into one network is the basis of convergence technologies. Benefits of Convergence ONE NETWORK – NO NEED TO MANAGE SEPARATE VDV NETWORK WHICH PRESENTS COST SAVINGS. ONE IT DEPT. COST EFFICIENT SERVICES FLEXIBILITY DESIGNERS NEED TO BE AWARE THAT SOME CONVERGED TECHNOLOGIES WILL NOT RUN WITH SOME OF THE CURRENT TRANSMISSION PROTOCOLS
Let now talk about the types of cabling and what's run over them. FIBER DISTANCES CAN RANGE FROM 10 METERS TO 10 KILOMETERS SO THE PROPER SELECTION OF F/O CABLE WITH RESPECT TO NETWORK SPEEDS IS A MAJOR CONSIDERATION.
AS DISCUSSED ON THE LAST SLIDE THE TRANSMITTER TYPE AND THE TRANSMITTED WAVELENGTH EFFECT THE FIBER DISTANCE CAPABILITIES TRANSMITTER CONVERTS ELECTRICAL SIGNAL TO LIGHT THE TRANSMITTERS EMIT LIGHT AT A SPECIFIC WAVELENGTH. THE HIGHER THE WAVELENGTH THE FURTHER THE DISTANCE AND MORE BANDWIDTH IS AVAILABLE.
Cat3 still used for voice – primarily in the horizontal Cat5 is now obsolete CAT5e Very large installed base – Contractor knowledgeable Quick terminations and testing LESS STRINGENT INSTALLATION REQUIREMENTS Capable of running Gbe Cannot handle 10Gbe Will not be manufactured, both cable or connector Will become obsolete when 7 is standardized
BANDWIDTH IS THE INFORMATION CARRYING CAPACITY OF A SYSTEM AND IS MEASURED IN Mhz. FIBER – BANDWIDTH IS A EXTREMELY COMPLEX MATHMATICAL EQUATION COPPER – YOU GET WHAT YOU GET WITH COPPER, THE BANDWIDTH OF COPPER IS REALLY PUSHED TO THE LIMITS WITH TODAYS TECHNOLOGIES SPEEDS ARE INCREASING MORE RAPIDLY THAN THE BANDWIDTH CAN ACCOMODATE, THUS PUSHING THE CABLE INFRASTRUCTURE TO ITS LIMITS
The minimum standard compliant cable today CAT5e Very large installed base – Contractor knowledgeable Quick terminations and testing LESS STRINGENT INSTALLATION REQUIREMENTS Capable of running Gbe Cannot handle 10Gbe Will not be manufactured, both cable or connector Will become obsolete when 7 is standardized
NOW LETS GET INTO SOME OF THE NEWER TECHNOLOGIES A Wireless LAN (WLAN) is a grouping of network components connected by electromagnetic (radio) waves instead of wires. Mobile- you can move around reliable - fewer wires and connectors means fewer problems ease of install - fewer cables to install, one cable per access point location affordability - installation and product life cost are lower scalability - easily configured and rearranged to meet many settings and # of users SECURITY – INFORMATION IS IN THE AIR AND HACKERS ARE FREE TO ACCESS IT. SPEEDS - SLOW AND SHARED
802.11a 54 Mbps at the 5Ghz frequency – SAME AS CORDLESS PHONES 8 separate non overlapping channels 802.11b 11 Mbps at the 2.4 Ghz frequency 3 non-overlapping channels 11a and 11b are not compatible, separate networks 802.11g – NEWEST TECHNOLOGY Extension of 11b STANDARD 54 Mbps at the 2.4 GHz frequency Backward compatible with 11b meaning device with a 11b card will interface with an 11g access point at 11 Mbps or lower 802.11n Standard end of 05 early 06 Product mid 06 100 Mbps or faster Spread spectrum Frequency hopping
QOS - DEFINE NEEDED WITHIN THE DATA HARDWARE INFRASTRUCTURE COSTLY UPGRADE ADVANTAGES LOWER COSTS PER CALL - IP TELEPHONY / BUILDING TO BUILDING LOWER INFRSTRUCTURE COSTS ONE CABLE INFRASTRUCTURE MOVES ADDS AND CHANGES ARE VERY SIMPLE – THE PHONES HAVE IP ADDRESS UNIFIED MESSAGING CONNECTS WORKERS TO VOICE MAIL, EMAIL, FAX WHENEVER THEY NEED THEM FROM ANY DEVICE, CELL PHONE, PDA, LAPTOP DISADVANTAGES: VERY DIFFICULT IMPLEMENTATION NETWORK OUTAGES VIRUS PROBLEMS OTHER TECHNOLOGIES WILL NOT RUN WITH VOIP Gbe AND 10Gbe
WHITEBOARDS DIFFERENT CONNECTOR TYPES PER MANUFACTURER DIFFERENT MOUNTING ARRANGMENTS THAT EFFECT THE LOCATION ON THE PRESENTATION WALL DISTANCE LEARNING REQUIRES HIGH SPEED WAN CONNECTIVITY HIGH TECH VIDEO AND SOUND SYSTEMS PROJECTORS TODAYS PROJECTORS CAN BE NETWORKED FOR CATV AND VIDEO PRESENTATION. THEY ALSO HAVE THE CAPABILITY OF REMOTE MONIORING AND EMAIL NOTIFICATION.
MEDIA RETRIEVAL SYSTEM – VIDEO HEADEND SYSTEM WITH THE CAPABILITY OF TRANSMITTING CD/DVD OR BROADCAST VIDEO OVER THE UTP INFRASTRUCTURE. LARGE A/V ROOM FULL OF EQUIPMENT. IN A SCHOOL ENVIRONMENT THE PRINCIPAL CAN MAKE MORNING MESSAGES OVER THE TV OR PROJECTOR, VCR AND DVD’s ARE NOT REQUIRED IN ANY CLASSROOMS SECURITY TODAYS CAMERAS ARE RUN OVER THE UTP INFRASTRUCTURE GIVING THEM THE CAPABILITY OF UTULIZING POWER OVER ETHERNET NETWORK CONNECTIVITY GIVES THE SECURITY STAFF ACCESS TO THE MEDIA RETRIEVAL SYSTEM AND DVR”s. RECORDING IS DONE ON THE HARD DRIVE, IS EASIER AND QUICKER TO ACCESS THAN A VHS TAPE SPECIALTY SYSTEMS - EXPLAIN
THE ABILITY TO RUN POWER OVER 2 OF THE PAIRS OF THE UTP CABLE Midspan – a separate device injects power onto the unused pair UP TO 48 VOLTS
10 YEARS AGO THROWING IN A CAT5 UTP CABLE WOULD BE SUFFICIENT TO HANDLE THE TRANSMISSION SPEEDS AND TECHNOLOGIES OF THE DAY. THE DESIGNER NEEDS TO BE AWARE OF WHAT TECHNOLOGIES ARE TO BE RUN ON THE CABLE INFRASTRUCTURE BECAUSE CERTAIN TECHNOLOGIES ARE NOT COMPATIBLE AND IF THEY DO NOT HAVE THE APPROPRIATE CABLE AND OR ELECTRONICS THE SYSTEM WILL NOT FUNCTION AS DESIRED VARYING DISTANCES WITHIN THE BACKBONE AND CAMPUS ENVIRONMENTS 3 WINDOWS OF TRANSMISSION THEY BOTH UTULIZE ALL 4 PAIRS OF THE UTP CABLE UTULIZES THE 2 UNUSED PAIRS YOU CAN’T RUN GBE OR HIGHER IN THE HORIZONTAL VOIP CANT RUN GBE OR HIGHER EFFECTS BACKBONE DESIGN (NO COPPER BACKBONE)
