Abstract
An optical network transmission channel failover switching device is proposed, which is designed for use with an optical network for providing the optical network with a transmission channel failover switching function, and which is characterized by the provision of a pair of one-to-two (1.times.2) type of optical switch and a monitoring beam generating module for providing a backup channel monitoring function that can be used to activate the switching action. This feature allows the utilization of the optical network system to have enhanced reliability, serviceability, and security.
