OAM controll system in an optical network

摘要: In a first node of an optical network, OAM (operations, administration and maintenance) controller produces electrical signal to control cross-connect switch. This is converted optically multiplexed with payload associated path established in the switch, producing multiplex which transmitted. A second network demultiplexes transmitted into signal, latter being used by for updating information. The updated information switch node. demultiplexed
