ABSTRACT:
An optic fiber wavelength multiplexer-demultiplexer comprising a dispersing system (1) exhibiting a dispersing plane, at least one input fiber (2) with an output face, at least one output fiber (3) with an input face, and a device (4) for optic matching of the output face of the input fiber with the input face of the output fiber. The dispersing system and the matching means form an optic system with multiple transversal focuses (6) in the dispersing plane.
