Polarization Division Multiplexing Coherent Optical OF DM Transmission Systems


Abstract –High-capacity and long-haul transmission technologies are indispensableto develop cost-effective optical transport networks. Optical communication is rapidlyadvancing toward 1-Tera bit per second (Tb/s) and beyond transport. As the availablebandwidth of Standard Single-Mode Fiber (SSMF) is limited, high Spectral Efficiency(SE) becomes an important issue. Coherent Optical Orthogonal Frequency-DivisionMultiplexing (CO-OFDM) has become one of the promising candidates due to its highSE and resilience to linear channel impairments such as Chromatic Dispersion (CD).In this paper, based on Optisystem 11.0 software simulation platform, the performanceof a 1.6 Tb/s (16 x 100 Gb/s) PDM-CO-OFDM transmission system is investigatedinvest by using QPSK modulation format and applying Polarization InterleavingScheme (PIS) over 1440 km with 2 b/s/Hz spectral efficiency.
