Title: Optical network transmission channel failover switching device

Abstract: An optical network transmission channel failover switching device is proposed, which is designed for use in conjunction with an optical network for providing a transmission channel failover switching function, which is characterized by the provision of a pair of two-to-two (2.times.2) optical switches and an optical transceiver module for providing a backup channel monitoring function that can be used to activate the failover switching action. This feature allows the utilization of the optical network system to have enhanced reliability, serviceability, and security.
