Experimental demonstration of soliton propagation in long fibers: loss compensated by Raman gain

Abstract

With sufficient Raman gain to compensate exactly for net fiber energy loss, we have demonstrated distortionless propagation of 10-psec FWHM fundamental (N = 1) soliton pulses (lambda = 1.56 microm) over a 10-km length of single-mode fiber. The implications of this experiment for development of an all-optical, high-bit-rate, long-distance telecommunications system are discussed briefly.
