Abstract
A photoelectric cross-connect system for an optical-communication system minimizes service recovery time when an error is generated. A plurality of nodes are connected by an optical-transmission line wherein each nodes automatically recognizes a data rate of an input signal and communicates over a redundant channel with an adjacent node when there is a certain type of error. An optical-receiving unit receives an optical signal performs O/E conversion. A main optical-transmitting unit recovers clock and data signals according to the converted signal and sets a data rate according to the converted signal for subsequent transmission; a redundant optical-transmitting unit recovers a clock and data according to the converted signal and sets a data rate according to the converted signal for subsequent transmission A switch provides selectively connection state between the optical-receiving unit and the main optical-transmitting unit and between the optical-receiving unit and the redundant optical-transmitting unit.
