Abstract:
1. A method for processing overheads in an optical communication system, comprising: in a signal receiving direction, conducting an optical/electrical conversion, a serial/parallel conversion for the received optical signal, separating parallel overheads from the optical signal, extracting overheads necessary for overhead processing from the separated parallel overheads, conducting a parallel/serial conversion for the extracted overheads to generate a serial overhead frame, and outputting the serial overhead frame; and receiving the outputted serial overhead frame, conducting a serial/parallel conversion for the serial overheads in the received frame, and reverting parallel overheads for overheads processing by inserting fixed reserved overheads into the overheads which are obtained by conducting the serial/parallel conversion for the serial overheads in the received frame; in a signal transmitting direction, generating parallel overheads to be transmitted, extracting overheads necessary for overheads processing from the generated overheads, conducting a parallel/serial conversion for the extracted overheads to generate a serial overhead frame, and outputting the serial overhead frame; and receiving the serial overhead frame outputted, conducting a serial/parallel conversion for the serial overheads in the received frame, reverting the parallel overheads by inserting fixed reserved overheads into the overheads which are obtained by conducting the serial/parallel conversion for the serial overheads in the received frame, combining the reverted overheads with payload data of the system, conducting a parallel/serial conversion, an electrical/optical conversion, generating and transmitting obtained optical signals.
