摘要： The present invention has an object to obtain an optical signal quality supervisory device that supervises the quality of an optical signal simply, efficiently and with high accuracy without inviting an increase in cost, an increase in circuit scale and increase in power consumption. The bit rate of the optical supervisory channel is made lower than the bit rate of the optical main channel that is transmitted over an optical communication system, but the reception electric band width of a receiver that receives the optical supervisory channel is made equal to or wider than the reception electric band width of a receiver that receives the optical main channel. Also, the optical supervisory channel is made up of an SOH (section over head) frame to detect an error of the BIP (bit interleaved parity) byte of SOH, thereby supervising the quality of the optical communication system, in particular, the light wave network.

摘要： An optical signal quality monitor for simply monitoring the quality of an optical signal with high efficiency and accuracy without inviting increase in manufacturing cost, circuit scale, and power consumption. The bit rate of a monitoring signal light beam is lower than that of a main signal light beam transmitted in an optical communication system. The reception electric bandwidth of a receiver for receiving the monitoring signal light beam is equal to or wider than that of a receiver for receiving the main signal light beam. The monitoring signal light beam includes an SOH (Section Over Head) frame. Any error in the BIP (Bit Interleaved Parity) bytes of the SOH is detected. Thus, the quality of an optical communication system, especially a light-wave network is monitored.
