A SYSTEM AND A METHOD FOR VIRTUAL CONCATENATION SYNCHRONIZATION IN OPTICAL TRANSPORT NETWORK

摘要

A system and method for virtual concatenation synchronization in optical transport network are disclosed in this invention, which is related to optical communication field. The said system comprises a synchronization module, a virtual concatenation delay compensation module, an asynchronous demapping module, a smoothed service obtaining module and a service data recovery module. The said method comprises: using OPUk fixed point floating in synchronization; recovering service data by combining virtual concatenation compensation and asynchronous demapping. The said technical scheme provided in this invention can suppress jitter caused by synchronization and virtual concatenation delay compensation and solve the problem of clock jitter target deterioration caused by fixed bit rate data transported by OTN virtual concatenation.
