Abstract:
1. A method of substantially maintaining an established error count for data transmitted on a WDM optical communication network, said method comprising: obtaining a previous interval FEC error count associated with data transmitted from a transmitter to a receiver on one of a plurality of channels of said network; comparing said previous interval FEC error count to a reference error count associated with said channel; adjusting one of a plurality of different operational parameters associated with said channel in response to a difference between said previous interval FEC error count and said reference error count, said plurality of different operational parameters including a channel pre-emphasis parameter, at least one operational parameter of said transmitter and at least one operational parameter of said receiver; and repeating said obtaining, comparing and adjusting steps to adjust each of said plurality of said different operational parameters associated with said channel on an automatic basis, whereby each of said different operational parameters is adjusted periodically at a different predetermined time.
