Coherent Systems, CO-OFDM, Spectral Efficiency, Superchannel, Terabit transmission


The development of coherent optical transmission technologies is impacting the design of the future optical networks. The increase in coherent transmission spectral efficiency (SE) in wavelength division multiplexing (WDM) systems is a strong research topic. High order quadrature amplitude modulation (QAM), Nyquist pulse-shaping and forward error correction coding are among digital transmission techniques being tested in optical coherent systems. Also, different optical implementations of orthogonal frequency division multiplexing (OFDM) were proposed for the next generation systems. In this paper, we investigated the performance of a 1.15-Tb/s (23x50-Gb/s DP-QPSK) superchannel with 3.75 b/s/Hz, using no-guard-interval orthogonal frequency division multiplexing (NGI-CO-OFDM), over pure silica core fiber (PSCF) and using erbium doped fiber amplifiers (EDFAs) only. A maximum reach of 4520 km was obtained. This result demonstrates reliability of these systems on fibers with regular effective area, unlike majority of related works that used large effective area fibers to demonstrate long haul performance.
