Broadband Delivery

• HFC – Hybrid Fiber Coax

• PON – Passive Optical Network

• xDSL – Digital Subscriber Line

Page 3: Broadband Services Primer

HFC• Traditional CATV Network – Comcast,

Time Warner, Charter, Cox, etc.

• Shared BW – VoIP, Data

• RF – Video - Broadcast

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

Page 8: Broadband Services Primer

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

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

• Splitter/Filter

– Eliminate out of Band Noise

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)
