CHROMATIC DISPERSION-COMPENSATING OPTICAL FIBRE IN THE S-BAND USING A HIGHER ORDER MODE

摘要

The invention relates to an chromatic dispersion-compensating optical fibre in the S-band, for use in compensating for the chromatic dispersion of either a standard SMF optical fibre or of an NZ-DSF optical fibre, carrying an optical signal in the spectral band in use, which is the S-band extending from 1460 nm to 1530 nm. The chromatic dispersion-compensating optical fibre in the S-band has a wavelength corresponding to the global chromatic dispersion minimum, which is situated outside the spectral band in use, that is to say outside the S-band.
