光网络发展面临的挑战与对策

Challenges and countermeasures for the development of optical network

近年来,以FTTH和5G为代表的固定和移动宽带业务的迅猛发展,给国内运营商光网络带来新的发展机遇的同时,也对网络架构和容量提出了更高的要求。为了应对日益增长的网络流量压力,新的光网络技术正在不断地被研究。对ROADM网络发展和挑战、光网络开放和分解以及5G承载等问题进行探讨。

In recent years, along with the rapid developments of the FTTH fixed broadband and 5 G mobile broadband services, both development chances and capacity challenges have been brought to the carrier’s optical networks of China. To cope with the rapidly growing network traffic, new optical network technology has been continuously developed. Here we discuss the developments and challenges of ROADM, open and disaggregation of optical network and 5 G bearing networks.
