摘要
随着数字与光通信技术的进步,原有的xDSL在满足人们综合业务接入的需求方面已日渐乏力,PON技术应运而生。在多种PON技术中,GPON以其独特的封装格式、灵活的上下行速率、优良的OAM功能及全业务数据的支持,成为该领域的研究热点。文中就GPON系统实现综合业务接入的方案作了探讨。在此基础上,给出了一种可行的三网融合方法。
As the development of digital and optical communications, the original xDSL could not meet the need of Multi-service access, so the PON technique emerges as the times require. In various PON techniques, GPON has become the study hotspot in the area with its unique encapsulation format, flexible upstream and downstream speed, excellent OAM function and multi-service data access. This paper discusses the scheme for implementation of multi-service access based on GPON system, and hopes that this could serve as a referrence in the filed of network triple play.
