Abstract
We study an electronic compensator (EC) as a receiver for a 100-Gb/s
polarization division multiplexing coherent optical orthogonal frequency division
multiplexing (PDM-CO-OFDM) system without optical dispersion compensation. EC,
including electrical dispersion compensation (EDC), least squares channel estimation
and compensation (LSCEC), and phase compensation (PC), is used to compensate for
chromatic dispersion (CD), phase noise, polarization mode dispersion (PMD), and
channel impairments, respectively. Simulations show that EC is highly effective in
compensating for those impairments and that the performance is close to the
theoretical limitation of optical signal-to-noise rate (OSNR), CD, and PMD. Its
robustness against those transmission impairments and fiber nonlinearity are also
systematically studied.
