Abstract
A virtual concatenation method for optical channels in WDM networks. In transmission, the method includes providing for a plurality of frames, each frame including a byte reserved for a concatenation flag; writing the same predefined value in the concatenation byte of n frames (n=1, 2, 3, . . . ); and transmitting the n frames via n respective channels (λ, λ, . . . λ). In reception, it includes receiving the first reference frame at one instant; reading the concatenation byte value of the reference frame; receiving the remaining signal frames after a respective determined time; reading the value of the concatenation byte of the remaining signal frames; and identifying and aligning all the signal frames with the same concatenation byte value compensating the reception times.
