Performance analysis of a dispersion managed soliton transmission system

This paper reports the design, implementation and the performance analysis of a lossless and dispersion managed soliton transmission system for long haul fiber optic communication. The soliton pulses are so stable that their shape and velocity are preserved while travelling long distances along a medium. This means that soliton pulses do not spread in optical fibre after propagating thousands of kilometres. Thus solitons are useful for data communication over several kilometres of distance. In an optical fibre, solitons pulses are generated by counter balancing the effect of the dispersion with the Self-Phase Modulation (SPM). A soliton has to retain its power between specified levels to preserve its dispersion resilient nature in an optical link. To achieve the lossless and dispersion managed soliton, dispersion compensated fiber and periodic amplification is used. Eye diagram, dispersion map and optical spectrum are used for the performance analysis.
