Phase Sensing Technology Based Optical Signal Regeneration for 40 Gb/s Optical System

In this paper, phase sensing technology based optical signal regeneration system is designed and developed for 40 Gb/s optical system. The designed technique has achieved the low bit error rate (BER) and high Q-factor for the long haul optical system of 200 km. In comparison to the existing systems, the proposed technique have achieved the low BER and high Q-factor for long noisy fiber link. In this work, the HNLF configuration based that varies the phase sensing during the optical signal regeneration for high-speed 40 Gb/s degraded optical system is developed. The designed phase sensing based optical signal regeneration system has achieved the BER of 10−21 with high Q-factor. The designed system can be used in the existing regeneration system to provide the noiseless communication for long haul optical systems.
