Abstract:
A method for performance monitoring and equalization of an optical link between two line terminating equipment (LTE/REGEN) sites of an optical network and being provided with at least one intermediate sites equipped with an optical add/drop multiplexers (OADM), comprising:selecting a direction of transmission and accordingly defining one of said LTE/REGEN sites as a source analogous end (AE) and the other as a destination AE; converting said optical link into a two-ended analogous system of J analogous channels (AC), each AC(j) originating at said source AE and terminating at said destination AE; and adjusting the input power of each AC(j) to obtain a substantially equal performance parameter for all ACs, where J>2, j is the identifier of an AC, and j&egr;[1,J].
