Abstract
We propose and demonstrate a bidirectional dense wave- length division multiplexing cable television system that uses large effec- tive area fibers (LEAFs) as transmission fibers and chirped fiber grating (CFG) as a dispersion compensation device to reduce the dispersion and cross-phase modulation (XPM)-induced crosstalk. By comparing the system link with the transmission length of a 50-km single-mode fiber (SMF) without CFG, good performances of carrier-to-noise ratio (CNR) >50 dB, a composite second order (CSO) >69 dB, and a composite triple beat (CTB) >66 dB are obtained in our proposed system over a 50-km LEAF transport. © 2003 Society of Photo-Optical Instrumentation Engineers.
