  1. 1. Commsday 2013: How to Efficiently Transition to an All-Fibre Future Robert Conger Director, Product Management October 9, 2013
  2. 2. ADTRAN Company Confidential® Adtran, Inc. 2013 All rights reserved 2 Key Trends in Fixed Broadband Access Cloud Connectivity Residential Broadband Data Center Connectivity Mobile Services Expansion Increased investment and competition Multiple services over a common network: - Residential broadband - Cloud connectivity - Mobile backhaul GPON and Vectored VDSL2 leading the way in telco markets Success-based approach to incremental fibre investment
  3. 3. ADTRAN Company Confidential® Adtran, Inc. 2013 All rights reserved 3 Typical Wireline Access Network Pillar
  4. 4. ADTRAN Company Confidential® Adtran, Inc. 2013 All rights reserved 4 Incremental Fibre Investment ~$350-$450 Per subscriber $1,000-$2,500 Per subscriber $600-$1,250 Per subscriber Aerial or Underground Distribution Cable Drop Cable Copper FTTDP Architecture (200-500+Mbps service) Fibre Distribution PointFTTCab Architecture (50-100Mbps service) Fiber Aggregator Aerial or Underground Distribution Cable Drop Cable Feeder Fiber CopperFibre Cross-Connect Cabinet $ $$ $$$ High Cost Area (last 1km) Common Network Architecture + $250-800 + $600-1,250 Drop Cable FTTP Architecture (1Gbps service) Fibre • General industry trend is towards a success-based fibre build • Build networks on a common FTTx architecture and then make decision on how far to invest with fiber vs. copper based on range of factors (competitive environment, service offering, deployment costs, etc.)
  5. 5. ADTRAN Company Confidential® Adtran, Inc. 2013 All rights reserved 5 FTTx Deployment Costs Understanding Cost Variations for FTTP Cross- box / Pillar Key Factors Driving FTTx Costs: – Greenfield vs. Brownfield – Aerial vs. Underground Utilities – Construction Costs – Subscriber Density – Wiring environments: SFUs vs. MDUs – Customer Sign-up Rates Range of factors influence how far to pull fibre into the network
  6. 6. ADTRAN Company Confidential® Adtran, Inc. 2013 All rights reserved 6 GPON and VDSL2 Market Analysis Strong growth in VDSL2 expected over next 5 years GPON market still very targeted GPON Revenue by Region: Q4 ‘12 Projected VDSL2 Growth by Region Source: Infonetics Q4 2012 Broadband Aggregation Report
  7. 7. ADTRAN Company Confidential® Adtran, Inc. 2013 All rights reserved 7 100 Mbps @ 550m with vectoring Vectoring Gain Vectoring eliminates Far End CrossTalk (FEXT) and allows service providers to deploy 100 Mbps out to >1 km over two pairs of copper VDSL2 with Vectoring Mass-Market 100 Mbps Service Delivery VDSL2 w/ Vectoring: – Latest generation copper access technology for FTTN architectures – Mass deployable technology in 2013 – Delivers 100Mbps out to >1km with 2pr bonding – Enables cost-effective and widespread delivery of 100M services – Small form-factor DSLAMs optimized around vectoring coming to market ~75% of customers within 500m of node, 90+% within 1km Note: Average ETSI market statistics
  8. 8. ADTRAN Company Confidential® Adtran, Inc. 2013 All rights reserved 8 Historical FTTN Deployment Model: Large adjunct cabinets next to existing cross-connect Current FTTN Model: Small footprint electronics that minimize throw-away construction costs 1m Changing the FTTN Deployment Model Minimizing Footprint and Constructions Costs
  9. 9. ADTRAN Company Confidential® Adtran, Inc. 2013 All rights reserved 9 Optimizing FTTDP Deployments Above or Below-Ground w/ Remote Powering Solutions must be optimized for below-ground pits, curbside pedestals, or aerial drop Vectored VDSL2 today and G.Fast in the future Network powering and reverse powering to avoid local powering requirements FTTDP solutions optimized for low- denstiy-environments
  10. 10. ADTRAN Company Confidential® Adtran, Inc. 2013 All rights reserved 10 Deep fibre is making loops shorter…. And shorter… CO/Exchange Remote Terminal or Street Cabinet Small Form-factor sealed DSLAMs Distribution Point under Footpath Incremental FTTx Requirement: Solutions Optimized for Each Deployment Model Incremental FTTx Strategy Solutions Optimized for Each Part of the Network
  11. 11. ADTRAN Company Confidential® Adtran, Inc. 2013 All rights reserved 11 GPON/NGPON GigE FTTH Deployment Business Services Metro Network N x 10Gig Ethernet or OTN Ethernet and Wavelength Services Small Cell Gateway Bonded VDSL2 Solutions Optimized for Multi-Service Delivery: – Platforms built with a range of vectored VDSL2, GPON, GE, 10GE, and wavelength service delivery options – Full network automation with zero touch provisioning – Integrated service assurance and optional redundancy for business and wholesale service delivery – Elimination of multi-box solutions to deliver a mix of residential, enterprise and backhaul services Multi-Service Support Solutions Must Support Full Range of Services
  12. 12. ADTRAN Company Confidential® Adtran, Inc. 2013 All rights reserved 12 Summary Exchange Remote Node Incremental Transition to FTTP VDSL2 GPON How to Efficiently Transition to an All-Fibre Future: – Minimize throw-away construction costs and footprint associated with FTTN and FTTDP electronics – Avoid “one size fits all” approach: utilize a range of solutions optimized for different deployment densities and locations – Avoid multi-box solutions to support a range of enterprise, residential, and backhaul services – Build out the network in a manner that is progressing towards long- term FTTP target architecture: incremental fibre investment, GPON- fed FTTDP ONUs, etc.
