PON+EoC solution Docsis： Data-Over-Cable Service Interface Specifications CMTS：Cable Modem Termination Systems CM： Cable Modem EoC：Ethernet over Coax（only used in china） CLT: Coax Line Terminal EoC Master CNU: Coax Network Unit EoC Slave 国际国内市场推广策略 国内：EPON+EoC技术已经被广大认可。推广策略： 1）针对EPON，EoC分开集采的广电，包装成EPON产品支持所有EoC技术。 2）针对EPON+EoC整体集采的广电，推进EPON+EoC整体方案。在推进过程中，强调统一网管，VLAN规划，淡化EoC调制技术。 国际：目前在CMTS仍然占有20%的宽带接入的市场份额，而xPON+EoC作为中国广电倡导的方案，仅在国内cable接入市场有一定份额。因此，在国际的推广过程中，CMTS是绝对无法回避的障碍。推广主要从CMTS发展历史引入，指出CMTS网络架构，带宽等各方面的问题。然后引出PON+EoC解决方案。 Agenda DOCSIS Trend ZTE PON+EOC Solution EPON+EOC Trial Network CATV network DOCSIS system CMTS Problems 64QAM is usually used in DownStream ,So 38Mbps (DownStream) 16QAM is usually used in UpStream, So 10Mbps (UpStream) CMTS UpStream P2P, waste 4~6 trunk fiber cables CMTS system occupy much more space than PON One NMS to manage all equipments is impossible, such as optical receiver/transmitter, electronic amplifier CMTS only for home subscribers, not for commercial users ZTE PON Solution for TWC Agenda DOCSIS Trend ZTE PON+EOC Solution EPON+EOC Trial Network PON+EOC Total Solution: Fiber Part PON+EOC Total Solution: Cable part PON+EOC Solution: Data transfer Profile of EOC Specification of interface Work Frequency ：2~30MHz (low frequency, less attenuation) Bandwidth: 28MHZ MAC mode: TDMA MAC Rate：57Mbps, （Q1/2010: 120Mbps ） MAX Attenuation: 70dB Maximum User：64 EoC Jumper 全系列的终端 Unified NMS Agenda DOCSIS Trend ZTE PON+EOC Solution EPON+EOC Trial Network EPON+EOC Trial Network (EPON Part) EPON+EOC Trial Network (EOC Part1) EPON+EOC Trial Network (EOC Part2) EPON+EOC Trial Network (EOC 2-WAY AMP) * Central office Sub-headend room FN BLOCK splitter splitter 发射机 秘密▲ Central office Sub-headend room Fiber Point room BLOCK OLT in sub-headend room ONU in fiber point room splitter splitter Ethernet cable Optical fiber CATV cable CATV Internet internet ONU EMS VOD service platform OLT PON+LAN solution PON+
