Optical fibre dispersion compensation technique for an optical communication system

摘要

An optical communication system for compensating dispersion of an optical fiber serving as a transmission path is provided. In its simplest form of configuration, a dispersion compensating fiber having a sufficient length to compensate the chromatic dispersion of the optical fiber (100a) is divided into portions (200a, 200b) each having a length to maintain a linear characteristic of a relative intensity noise of the dispersion compensating fiber, and the divided portions (200a, 200b) of the dispersion compensating fiber are inserted in the path of the optical fiber while they are optically separated.
