Abstract
An optical network backup channel switching control device is proposed, which is designed for use in conjunction with an optical network for providing a backup channel switching control function, and which is characterized by the capability of generating a main-channel monitoring beam and a backup-channel monitoring beam both on the local side and the remote side, where the main-channel monitoring beam is detected on the opposite side to determine whether the main channel is in good condition, and if a failure occurs to the main channel, the backup-channel monitoring beam is detected to determine whether the backup channel is in good condition. If the backup channel is in good condition, a switching action is then performed to switch the connection to the backup channel. This feature allows the optical network to have a higher level of reliability in operation.
