<p>The present invention discloses an overhead signal processing method and signal process device based on this method of optical communication system, at receiving direction includes: Carrying out optical / electricity series /parallel conversion on received optical signal, extracting overhead data needed by system overhead process; Serial transmitting the extractive overhead data; Carrying out series /parallel conversion on the received overhead data, adding in fixed obligate overhead byte, renewing the parallel overhead data, carrying out overhead process; At transmitting direction includes: Generating parallel overhead data, extracting the overhead data needed by system overhead; Serial transmitting extractive overhead data; Carrying out series /parallel conversion on the received serial overhead data, renewing parallel overhead data, and combining with transaction data, carrying out parallel/ series, electricity / optical conversion, generating transmission optical signal. The method and device of the present invention employ serial buses to transmit overhead data, reduce the bus number on the system motherboard, decrease the complexity degree of system design</p> |
