发明名称 System och förfarande för synkronisering i en SDH- eller SONET-demultiplexer
摘要 Transmitters (101) transmitting at a rate of 2.5 Gbit/second are connected to a converter (103) of incoming optical signals into corresponding electrical signals, which is coupled to a phase matching circuit (105) connected to a multiplexer (107) and a modulator unit (115) modulates the synchronization signal from a generator (113) or superimposes it on the 10 Gbit signal from the multiplexer. The obtained data signal is transmitted on an optical line (117) to a receiver, is converted into electrical format in a converter (119) and is fed to a synchronization recovery circuit, while a central processor (135) derives a signal indicating whether regenerating clocks (121,123) are synchronized. DETAILED DESCRIPTION - AN INDEPENDENT CLAIM is included for a synchronous multiplexed transmission system.
