摘要
随着业务的需求发展和外界条件变化等因素的影响,光网络经常性地需要改动,这种带业务的改动在网络维护中称为割接。把光传输网络改造割接分为光缆线路割接、光传输设备割接、业务电路割接三种割接方式,在一次割接中,可能是这3种割接中单独的某一种割接,也可能是两种或者3种割接同时并行。重点阐述分析了各类割接调整的特点和割接关键点的控制,通过对这些关键点的控制,就能保证光传输网络割接的安全平滑进行。
With the development of business and the change of external conditions, the optical network often demands modification, and this modification in network maintenance with business is called cutover. Transmission networks cutover are divided into three forms： optical cable cutover, optical transmission equipment cutover and business circuit cutover. In one cutover, it may be one form, two forms or even three forms together. This article emphatically analyzes their features and their key points. Through the control of these key points, the optical transmission networks cutover could be safely and smoothly conducted.
