AbstractAbstract –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.
