Patent ID: 7187824

Claim:
A module for compensating chromatic dispersion of a line optical fiber ( 1 ) in a plurality of contiguous and non-overlapping spectral bands each covering at least 30 nanometers, characterized in that the module includes a structure ( 9 ) carrying a plurality of submodules ( 4 , 8 ) at least one of which is separable from the structure ( 9 ), which are disposed in series, which are interconnected by one or more connections ( 6 ) identifiable to the naked eye without optical measurement and accessible from the outside without damaging the module, and each of which includes a support to which is fixed at least one optical fiber ( 2 , 7 ) for compensating chromatic dispersion, at least one optical fiber ( 2 ) of said plurality of compensation optical fibers ( 2 , 7 ) having a compensation ratio from 0.9 to 1.1 for the center wavelength of one of said spectral bands, at least two submodules ( 4 , 8 ) having compensation optical fibers ( 2 , 7 ) of different kinds.
