ROADM智能光网络的本地配置方案

Local Configuration Scheme for ROADM Intelligent Optical Network

随着运营商业务的高速发展及5G移动网的灵活承载需求,在本地网市县中继波分引入可重构光分插复用(Reconfigurable Optical Add-Drop Multiplexer,ROADM)技术,满足业务的高效恢复及业务的灵活调度是目前本地网市县中继波分组网的重点和难点。本文简要介绍了ROADM三种设备形态,分析了自动交换光网络(Automatic Switched Optical Network,ASON)技术,结合本地网网络结构特点,建设CD-ROADM网络引入ASON功能的必要性。

With the rapid development of operator services and the flexible carrying demand of 5G mobile networks,the introduction of Reconfigurable Optical Add Drop Multiplexer(ROADM)technology in local network city and county relay wave division is currently the focus and difficulty of local network city and county relay wave grouping networks to meet the efficient recovery of services and flexible scheduling of services.This article briefly introduces the three forms of ROADM devices,analyzes the Automatic Switched Optical Network(ASON)technology,and combines the characteristics of the local network structure to demonstrate the necessity of introducing ASON functionality into the construction of CD-ROM networks.
