多接入方式融合的1550 nm接入网传输模型设计与应用

Design and Application of 1550 Transmission Model Based on Multi Access Mode Integration

以有线电视FTTH网络发展演进为契机,设计一种可以灵活适配现有网络多种接入方式使用的1550nm电视下行传输模型,通过合理分配业务容量配比和增加冗余保护机制,使其在经济性、安全性、资源利用等方面得到了显著提升。

Taking the advantage of the development and evolution of CATV FTTH network,this paper provides a design of the 1550nm TV downlink transmission model which can flexibly adapt to various access modes of the existing network.By reasonably allocating the service capacity ratio and increasing the redundancy protection mechanism,it has significantly improved in the aspects of economy,security and resource utilization.
