Abstract:
In this paper, we demonstrate the superchannel polarization division multiplexed coherent optical orthogonal frequency-division Multiplexing (PDM-CO-OFDM) system employing midway optical phase conjugation (OPC). The system is designed to show the optimum number of sub-carriers, amplifier spacing and the maximum achievement reach at data rate 1Tb/s (10x100 Gb/s). The system is simulated with 10-WDM superchannel at 50 GHz channel spacing. From the simulation results, PDM-CO-OFDM, with midway OPC and the optimum system parameters, we can achieve the maximum reachable distance of 24,000 km at BER 4x10-3.
