广电网络光分路器的选型

Radio and Television Network Optical Splitter Selection

在广电网络双向化浪潮的推进下,基于EPON(以太无源光纤网络)的新型网络结构被多数广电运营商采用。光纤网络中的无源光分路器是EPON网络中的重要环节。对基于EPON的网络结构中无源光分路器作一简述,并就无源光分路器的选型、分光路数设计结合实际网络状况做一些探讨。

Under the promotion of two-way radio and television network,the new network structure based on EPON(Ethernet Passive Optical Network)is adopted by most radio and television operators.Passive optical splitter in optical distribution network is an important link in EPON network.This paper briefly introduces the passive optical splitter in EPON-based network structure,and discusses the selection of passive optical splitter and the design of optical splitter combined with the actual network conditions.
