Paper Abstract

We present the designs of a small residual dispersion fiber (SRDF) and a corresponding dispersion-compensating fiber (DCF), where the dispersion slopes of these fibers are so adjusted that a small length of the DCF will approximately compensate the accumulated dispersion in SRDF simultaneously at all wavelengths in the range of 1530 to 1565 nm [gain window (C-band) of erbium-doped fiber amplifiers]. The maximum values of the effective dispersion and the slope of the effective dispersion in the wavelength range of 1530 to 1565 nm are ~0.08 ps/km nm and ~0.01 ps/km nm2, respectively.
