Experimental Demonstration of Fiber Nonlinearity Mitigation Using Digital Phase Conjugation
04 March 2012
We demonstrate fiber nonlinearity mitigation using mid-link digital phase conjugation in 40-Gb/s CO-OFDM-16QAM transmission over 100-km ultra-large-area-fiber spans, achieving a reach of 10,400 km, and reach and power-tolerance improvements of 53% and 4 dB, respectively. OCIS codes: (060.1660) Coherent communications; (060.5060) Phase modulation; (060.2330) Fiber optics communications
