Research on Synchronous Testing Method of OTN
摘要
Abstract
With the large-scale deployment of Optical Transport Network/Packet-enhanced Optical Transport Network (OTN/POTN)technology,the problem of bearing frequency and time synchronization signal in OTN/POTN occurs.This paper pro-poses a test method based on 1588+SyncE synchronous network.Through the configuration of additional Optical Supervisory Channel (OSC)board and clock interface board in source OTN/POTN equipment,and the point by point method was used for the synchronous signal to be tested in a local loopback mode.This scheme solves the problem of measurement error due to re-mote testing,while removing the restriction of test source and test reference point,and can be tested at any node of the OTN/POTN system according to actual needs,reduce the cost of testing.关键词
