摘要

随着40Gbit/s路由器的正式商用

中国电信从2009年中开始大规模建设单波速率40Gbit/s的高速率波分系统。40Gbit/s系统较10Gbit/s系统

有着更严格的色散要求

40Gbit/s系统除了要求固定色散补偿模块配置准确外

还在OTU上配置了色散可调模块TDC（Tunable Dispersion Compensator）

进行色散精确调整。由于TDC在全局搜索时

会引起业务的较长时间中断

因此40Gbit/s系统的业务恢复与10Gbit/s系统有较大的区别。本文就40Gbit/s波分系统的调度及OLP保护对业务的影响进行了探讨。

Abstract

40Gbit/s router with the official business

China Telecom started from 2009 in large-scale construction of high-speed single-wave velocity 40Gbit/s rate wave subsystems. 10/40Gbit/s system than the system

the dispersion has a more stringent requirement

40Gbit/s system requirements in addition to the fixed dispersion compensation module is configured for accuracy

is also configured on the dispersion OTU adjustable module TDC

for precise adjustment of dispersion. As the TDC in the global search

it will cause the business a long time interrupted

so 40G and 10G systems business recovery system differs greatly. In this paper

the scheduling and 40G WDM OLP business impact protection are discussed.
