Abstract :
This paper presents, for potential application to network failure restoration, an optical digital cross-connect system (DCS) which uses both a photonic switching network and an electric DCS. It is shown that a system constructed of LiNbO3 8×8 switch matrices and semiconductor traveling-wave optical amplifiers (TWA´s) could be applied to metropolitan area networks. An experimental optical DCS system has been designed and fabricated which incorporates both LiNbO3 switch matrices and TWA´s, and with it, line-failure restoration, a fundamental operation of optical DCS, has been successfully demonstrated
