高密度四路光发射机设计及在C—DOCSIS网络中的应用

Design of High Density Four-channel Optical Transmitter and Its Application in C-DOCSIS Network

C—DOCSIS＋RFoG作为广电双向接入网络技术，把C—DOCSIS局端从野外型光点设备升级为室内型分前端设备，从而使RFoG头端也需升级为室内型设备。从设计高密度四路光发射机出发，构建室内型C—DOCSIS＋RFoG分前端，网络光点处设置RFoG光站，实现高密度、低成本的新型C—DOCSIS接入网系统。

As a radio and television two-way access network technology, C-DOCSIS ＋ RFoG upgrades C-DOCSIS terminal from the wild type spot equipment into the indoor sub-front-end equipment, so that the RFoG head end also need to be upgraded to the indoor equipment. In this paper, from the design of high-density four-channel optical transmitter, the indoor C-DOCSIS ＋ RFoG sub-front end is built, and the RFoG optical station is set at the network optical spot in order to achieve the new C-DOCSIS access network system with high density and low cost.
