摘要

We proposed and demonstrated a bi-directional dense-wavelength-division-multiplexing (DWDM) CATV system which used chirped fiber grating (CFG) and large effective area fiber (LEAF) as dispersion compensation devices to reduce the dispersion and cross-phase modulation (XPM)-induced crosstalk. By comparing with the system link with a transmission length of 50 km single-mode fiber (SMF) without CFG, good performances of carrier-to-noise ratio (CNR) ≥50 dB, composite second order (CSO) ≥69 dB and composite triple beat (CTB) ≥66 dB were obtained in our proposed system over a 50-km LEAF transport.
