  • 1. IPTV Deployment via VDSL2 at the Customer Premises WSTA 2008 Annual Convention Lake Geneva, WI 5/21/2008
  • 2. Broadband Delivery • HFC – Hybrid Fiber Coax • PON – Passive Optical Network • xDSL – Digital Subscriber Line
  • 3. HFC • Traditional CATV Network – Comcast, Time Warner, Charter, Cox, etc. • Shared BW – VoIP, Data • RF – Video - Broadcast ~500 Homes CATV Fiber Node Head Tap O/E RG-11 End RG-8 www.speakeasy.net/speedtest/
  • 4. PON • Verizon FiOS Network (B/G) • Shared BW – Voice and Data • RF Video ONT UPS • Distance Independent FTTH ONT UPS Central Fiber OLU Office 1 x 32 OLT MDU’s MDU/ONT UPS OLU 1 x 32 VDSL2 (Some Cases)
  • 5. xDSL • Traditional POTS/ISDN/ADSL/SDSL Network – AT&T, Verizon, Qwest, etc. • Dedicated BW – Voice (POTS), Data • Distance Limited DSLAM Central Office UTP 25P Fiber SAI UTP 3/4P Remote UPS DSLAM O/E ADSL <18kft
  • 6. VDSL2 • System Upgrade from Traditional POTS/ISDN/ADSL/SDSL Network – AT&T, CenturyTel, Qwest, etc. • Dedicated BW – IPTV, Voice, Data • Distance Limited Remote UTP 25P Fiber UPS Central DSLAM SAI Office UTP 2P/4P O/E VDSL2 <3kft
  • 7. Bandwidth (3kft) • VDSL2 – Dedicated - 30Mbs • HFC DOCSIS 2.0 – Shared – 40Mbs – ~3Mbs* • HFC DOCSIS 3.0 – Shared (2010+) – 160Mbs – ~12Mbs* *Based on 500 HP/node and 30% TR • PON – Shared – 622-2488Mbs – ~20 - 40Mbs **Based on BPON/32 and GPON/64 split
  • 8. IPTV • 3SD/1HD takes ~25Mbs - 4HD ~37Mbs – 3mbs for SD and 7Mbs for HD with 6Mbs data • Efficient Transport of Video • Interactive Guide • Quick Channel Change
  • 9. Radio Frequency Interference (RFI) • RFI introduced into drop from DSLAM to subscriber • RFI is introduced from various sources – Bug Zapper – Dimmer Switch – All electronics and computers – Florescent light ballast – Motors – washing machine, refrigerators, etc. – RF controlled devices – Power Grid • Concentration of RFI in MDU’s • Filtering eliminates random noise from entering subscriber premises – optimizes Home Network Performance
  • 10. • Splitter/Filter – Eliminate out of Band Noise POTS VDSL2 Noise Noise
  • 11. Home Network - HPNAB • Home Network Connects all Components – DVR, Set Top Box, Computers • Home Wiring is the biggest challenge – Phone & Coax wiring in most Homes • Home runs best solution • Coax outlets in convenient locations – RG-6 or better – Minimize connections and splitters • Phone Wiring – At least Cat3 or better – No bridge taps • VDSL2-8a (25kHz-8.5MHz) HPNAB (12-28MHz)
