Polarization division multiplexing coherent optical of DM transmission systems

Abstract EN

High-capacity and long-haul transmission technologies are indispensable to develop cost-effective optical transport networks.

Optical communication is rapidly advancing toward 1-Tera bit per second (Tb/s) and beyond transport.

As the available bandwidth of Standard Single-Mode Fiber (SSMF) is limited, high Spectral Efficiency (SE) becomes an important issue.

Coherent Optical Orthogonal Frequency-Division Multiplexing (CO-OFDM) has become one of the promising candidates due to its high SE and resilience to linear channel impairments such as Chromatic Dispersion (CD).

In this paper, based on Optisystem 11.0 software simulation platform, the performance of a 1.6 Tb/s (16 x 100 Gb/s) PDM-CO-OFDM transmission system is investigated invest by using QPSK modulation format and applying Polarization Interleaving Scheme (PIS) over 1440 km with 2 b/s/Hz spectral efficiency.
