1前言接着上一章提及的RFoG方式,本文拟就RFoG方式的使用作一介绍。当前,CATV业者多在探讨着传送线路的高速化与FTTH化。但问题在于FTTH系统中,RF方式的双向化业务有难点。为此,出现了能在FTTH上开展RF双向业务的RFoG系统。但要求RFoG不仅能继续用于现有的DOCSIS设备,也能顺利地进行往GE-PON系统的转移。面临大竞争时代的CATV业界,RFoG可谓是一项一边控制(全光化)投资成本、一边又能实现网络高速化的良策。现介绍如下以供参考。
1 Preface Following the RFoG approach mentioned in the previous chapter, this article intends to introduce the use of the RFoG approach. At present, CATV operators are mostly discussing the transmission speed and FTTH. However, the problem lies in the FTTH system, RF-way bidirectional business difficulties. For this reason, the RFoG system that can carry out RF two-way business on FTTH appears. However, RFoG is required not only to continue with its existing DOCSIS equipment but also to successfully migrate to GE-PON systems. Facing the big competition in the CATV industry, RFoG can be said to be a good way to control the investment cost and speed up the network. Now introduce as follows for reference.
