摘　　要：为解决终端通信接入网重复建设及多种业务综合承载的问题,针对电力业务的安全隔离要求,结合电力系统终端通信接入网的建设现状,基于无源光网络(Passive Optical Network,PON)技术对承载电力综合业务的通信网技术方案展开了研究。通过将PON通信的设备接入技术与同步数字体系(Synchronous Digital Hierarchy,SDH)时隙通道原理进行结合,利用PON系统上下行通道时隙与业务逻辑通道建立一一对应的多业务PON时隙隔离链接,实现逻辑标识的时隙复用和时隙抢占的业务时隙隔离。方案整体上实现了业务在PON体系下的时隙隔离,为多种电力业务综合承载提供了一种可行的解决方法。To solve the problem of terminal communication access network redundant construction and multi business integrated bearing, considering the power system terminal communication access network construction situation and the safety isolation requirements of the electric power business, this paper studies the technical scheme of power communication network to carry multi business based on PON technology. Combing the PON communications equipment access technology with SDH time slot channel principle, using PON up and down channel time slot and business logic channel, this paper establishes one-to-one multi business PON time slot isolation links to implement the time slot multiplexing of logical identifier and time slot business time slot isolation of time slot contention. The scheme implements business time slot isolation in the PON system, and provides a feasible solution for mutli-carrying electric power business.
