Abstract

A CWDM multi-service transmission system used in metro-networks is proposed and demonstrated. In the system, two wavelengths, with channel spacing of about 5 nm and 6 nm in old band and C band, respectively, are multiplexed by using fiber tapered couplers, instead of using thin film filter couplers. The two multiplexed bands are doubly multiplexed in a fiber. The system is designed to transmit different kinds of signals including E1, IP, E3/T3 and etc in metro networks. So the system can be used to transmit four different kinds of network service in one fiber link. The designs of the whole system and the related subsystems are described in details, and the corresponding tested results are also given.
