DISPERSION TAPERED OPTICAL FIBERS FOR USE IN WDM SOLITON TRANSMISSION SYSTEMS

摘要

A dispersion-tapered fiber for use in a solitontransmission system having lumped amplifiers tosubstantially reduce loss associated with pseudo phasematching and to relax the limitations on minimumallowable channel spacing caused by cross-phasemodulation. The dispersion tapered fiber has adispersion tapered either continuously or in steps, inconformity with the fiber loss curve.
