Applicable to the accommodation and compensation of dispersion in fibre optic communication systems. Generally, dispersion compensation and accommodation is used in the 1550 nm region with cables incorporating conventional (dispersion-unshifted) single-mode category B1 fibre as shown in IEC 60793-1 and IEC 60793-2. In this wavelength region, the fibre has a positive dispersion coefficient that averages at about 17 ps/nm-km. There are two subcategories of such fibre. The cutoff wavelength of B1 fibre is low enough for the fibre to be used in either the 1310 nm or the 1550 nm region.
