PROBLEM TO BE SOLVED: To provide a method, system, and apparatus for optical communication.SOLUTION: One apparatus includes a plurality of ingress ports coupled to N units of 1×n splitters in which each 1×n splitter includes a plurality of cross connect ingress branches and a drop branch; a plurality of egress ports coupled to N units of n×1 combiners in which n×1 combiner includes a plurality of cross connect egress branches and an add branch; an M×M' fiber shuffle providing cross connect between the ingress branches and the egress branches so that each branch from an ingress 1×n splitter is linked to a branch of each n×1 combiner; and a wavelength blocker array comprising N×n wavelength blocker units where n≥N wavelength blocker units, each wavelength blocker unit coupled to a fiber of the M×M' fiber shuffle. |
