Gives Telcordia's preliminary view of proposed generic criteria for dispersion compensators meant for use in Bellcore Client Company (BCC) systems and other telecommunications networks. Generally, dispersion compensation is used to move the zero-dispersion wavelength of a length of dispersion-unshifted single-mode fiber from the 1310 nm region to the 1550 nm region. Dispersion compensation for 1550 nm operation over 1310 nm-optimized cable plant is of increasing importance to many system operators for OC-192 (10 Gb/s) transmission using EDFAs.
