广电EPON+FTTB网络ODN光缆纤芯规划设计

The Design Project of ODN Optical Fiber Core in Broadcasting&Television EPON + FTTB Network

FTTx及PON技术是当前电信升级、广电双改及下一代广播电视网络(NGB)双向接入网的主流技术。PON系统的ODN部分投入较大,ODN的建设要有前瞻性,ODN结构及其光缆纤芯规划需充分考虑今后能否满足FTTH的需求。为此提出了广电EPON+FTTB这一典型结构的ODN纤芯规划设计方法,并对PON系统ODN的分光结构进行分析。

FTTx and PON technic is the mainstream technology of 2-ways access network in telecom updating /Broadcasting & Television system bidirectional rebuilding / Next Generation Broadcasting( NGB) at present. The ODN of PON system will cast much,to start it need foresight,the project of ODN structure and optical fiber quantity should give full consideration to future FTTH request. Therefore proposed EPON + FTTB typical structure of ODN fiber core programming design method for Broadcasting & Television,to simple analyses ODN split fiber structure in PON system.
