光端机的技术在不断更新,单一功能的光端机在行业中也会逐渐被淘汰。如今,已不能简单的用模拟与数字去区分光端机,而是需要从实际应用去辨别对待。如从承载的业务类型上可分为视频光端机、数据/音频光端机、以太网光端机、多业务光端机等;从视频类型上又分为标清视频光端机、高清视频光端机和标清高清混合视频光端机;从拓扑上分为点对点光端机、链型光端机、环形光端机等;从网管的角度又分为网管型光端
Optical technology continues to update, single-function Optical in the industry will gradually be eliminated. Now, can not simply use analog and digital to distinguish optical terminal, but need to be treated differently from the actual application. For example, it can be divided into video optical transceiver, data / audio optical transceiver, Ethernet optical transceiver, multi-service optical transceiver etc. from the type of service carried; it is divided into SD video optical transceiver, HD video optical transceiver and SD HD mixed video optical transceiver from the video type; Split into point-to-point Guangduan Ji, chain-type Guangduan Ji, ring Guangduan Ji, etc .; from the network management point of view is divided into network-managed Optical
