Abstract :
Chromatic dispersion compensation is demonstrated in a 2.5-Gb/s system experiment using an elliptical-core dual-mode fiber operated in the LP/sub 11/ mode near cutoff. With a measured dispersion of -548 ps/nm-km for the LP/sub 11/ mode and a novel double-pass configuration, complete compensation of the dispersion in 50 km of conventional single-mode fiber at 1530 nm is achieved with 0.72 km of dual-mode fiber. System degradation due to remnant LP/sub 01/ mode power in the dual-mode fiber is investigated and found to be small for relative LP/sub 01/ power levels less than -20 dB.<>
