Abstract

The all-optical signal regeneration is a demanding research area for long haul optical communication systems. Electronic signal regeneration is limited due to its real-time infeasibility in terms of data rate and accumulated losses; therefore, all-optical signal regeneration is utilized to overcome these issues. The existing all-optical signal regeneration techniques have not been able to facilitate low power consumption, demonstration of real-time low cost commercial based design systems and application for the optical systems. In this research, a new all-optical signal regeneration technique is developed using single- pump Phase Sensitive Amplification, designed Optical Frequency Locked Model and noise mitigation model. The designed technique consumes less power than existing signal regeneration techniques for 10Gb/s optical degraded signal for different amplitude and phase modulation formats transmitted at different transmission distances between 50 km to 250 km. The designed all-optical signal regeneration technique is realized using numerically and verified using Simulink model. A real-time demonstration and commercial design based application is developed using Xilinx KCU105 UltraScale FPGA. The new all-optical signal regeneration technique has achieved a very low Bit Error Rate (BER) of 10-13 at low received power of -16 dBm averagely for different transmission distances between 50 km to 250 km via simulation and experiment. The new all-optical signal regeneration technique consumes low power of -16dBm, compared to existing all-optical signal regeneration techniques that consumes -9dBm. The new all-optical signal regeneration technique consumes 45% less power; with low BER and low received power compared to existing technique. The new all-optical signal regeneration system offers, real time implementation, live monitoring and commercial based design for Differential Phase Shift keying (DPSK) Non-Return-to-Zero (NRZ), DPSK-Return-to-Zero (RZ), Binary PSK (BPSK), Differential BPSK, Quadrature PSK, Orthogonal Frequency Division Multiplexing (OFDM), Quadrature Amplitude Modulation (QAM), Binary Frequency Shift Keying (BFSK), 8-PSK, and On-Off Keying (OOK).
