Abstract

Experimental verifications of the feasibility of using chirped fiber grating (CFG) as the dispersion compensation device in a bi-directional hybrid dense-wavelength-division-multiplexing (DWDM) system to reduce the dispersion and cross-phase modulation (XPM) induced crosstalk were proposed and demonstrated. Not only channel capacity was increased, but also good performances of carrier-to-noise ratio (CNR) ? 50 dB, composite second order (CSO) ? 72 dB, composite triple beat (CTB) ? 69 dB and low bit error rate (BER) <;;; 10^(-9) were achieved in our proposed system over a 50-km single-mode fiber (SMF) transport.
