OXC DEVICE IN OPTICAL COMMUNICATION NETWORK AND PROCESSING METHOD THEREFOR

摘要

PURPOSE: An OXC(Optical Cross Connect) device in an optical communication network and a processing method therefor are provided to reduce time delay according to a transmission speed automatic conversion in an opaque OXC. CONSTITUTION: An MCU(Main Control Unit) of a node B records a transmission rate in a dual port memory. A corresponding SCU(Supervisor Channel Unit) reads the transmission rate recorded in the dual port memory, and transmits the read transmission rate as an optical signal through an optical transmitter. A certain optical receiver of a node C receives the transmitted optical signal, converts the received optical signal into an electric signal, and transmits the electric signal to a corresponding SCU of the node C. The SCU of the node C records the electric signal in a dual port memory. An MCU of the node C reads transmission rate information recorded in the dual port memory, and stabilizes optical receivers and optical transmitters, using read transmission rate information.
