摘要:
The present invention provides an optical transponder with an add/drop operation function of optical channels, which combines operating functions of adding and dropping type optical transponders in accordance with mounting of a digital wrapper to simultaneously process two optical channels. The optical transponder receives an optical signal, converts the optical signal into electrical signal, adds maintenance information, monitoring information, and error correction information to each of the converted signals, and detects the maintenance information, monitoring information, and errors contained in each of the signals. Furthermore The optical transponder corrects the detected errors, and transmits the signals having the maintenance information, monitoring information, and error correction information and the signals of which errors are corrected.
