Abstract:

A method for optical layer management of an optical channel in an optical network includes inserting specific data patterns into a frame of an optical signal in the optical channel such that when a framing header is extracted from the optical signal, the specific data patterns are readily identifiable, the specific data patterns being indicative of respective line statuses of the optical channel. Additionally, a method for optical layer management of an optical channel in an optical network includes extracting a frame header from an optical signal in the optical channel and analyzing the optical signal for the presence of previously inserted specific data patterns, the specific data patterns being indicative of respective line statuses of the optical channel.
