摘要
介绍EPON和EOC技术的工作原理和主要特点,对基于EPON+LAN技术和EPON+EOC技术的广电双网改造方案进行论述,通过一个商住小区双网改造的设计实例,阐述EPON+EOC在双网改造中的设计思路。从中可以看出,EPON+EOC在双网改造中大大节省了网络建设投资,是住宅小区或者商业区改造方案的最佳选择,是广电行业实施"三网融合"的合适的网络改造方案。
This paper firstly introduces the work principle and main characteristics of EPON and EOC technology,and discusses the CATV network bidirectional reconstruction of the existing HFC network based on EPON＋EOC or EPON＋LAN.Through a bidirectional reconstruction design examples in commercial district,expounds the design ideas based on EPON＋EOC in CATV network bidirectional reconstruction.It can be seen that the EPON＋EOC technology can extremely save the investment in the network construction,which is the best choice for residence community and commercial district.It is the suitable network reconstruction solution for integrating telecom,broadcasting and Internet networks in China broadcasting industry.
