Abstract


The existing optical signal regeneration techniques are based on Optical- Electrical (O-E) conversion that has limited data rate, high electrical losses, and high Bit Error Rate Error (BER). In comparison, signal regeneration in the optical domain has the significant potential for signal renaissance without O-E conversion along with high data rate and low BER. However, all-optical signal regeneration is not technological mature enough. In this paper, the design and analysis of signal regeneration in the all-optical domain are demonstrated for the high-speed degraded optical signal. The signal regeneration in the optical domain for 40Gb/s DPSK-NRZ degraded signal is demonstrated based on 2-R regeneration for long haul degraded fiber link. The 2-R regeneration is achieved using Highly Nonlinear Fiber (HNLF). In result, for 50 km degraded optical link, the BER of 2.7*10-86 is attained. Similarly, for 100 km degraded fiber link, BER of 2.17*10-38 is attained using designed all-optical 2R- regeneration technique. The developed technique is tested via optisystem photonics simulations. In addition, for degraded links, the Q-factor of the degraded link is also significantly improved. It has been also demonstrated that the achieved BER and Q-factor is improvised using proposed techniques in comparison with an existing technique. The designed all-optical system will be helpful for existing signal regeneration to provide noiseless long haul optical signal transmission.
