Experimental comparison of optical phase conjugation and DCF aided DWDM 2x10.7Gbit/s DWPSK transmission

The performance of DWDM 2×10.7 Gbit/s-DQPSK is assessed comparing mid-link optical phase conjugation (OPC) and DCF for dispersion compensation. We report a 44%-increase in transmission distance resulting from nonlinear phase noise reduction by using mid-link OPC. (2 pages)
