Experimental investigation of the impact of NZDF zero-dispersion wavelength on broadband transmission in Raman-enhanced systems

Two nonzero dispersion fibers with different zero-dispersion wavelengths (ZDW) were evaluated for C+L-band, Raman-enhanced systems. With an optimized ZDW, 80/spl times/42.7 Gb/s transmission over 800-km can be achieved without forward-error-correction or per-channel post dispersion optimization.
