Abstract

A new dispersion compensation method for high-speed wavelength-division-multiplexing terrestrial systems with cascaded EDFAs was proposed. Specially designed dispersion-shifted fiber (SDDSF), generating -2 approximately -4 ps/km/nm dispersion around 1.55 micrometers is used to avoid severe four-wave mixing, while CCITT G.652 non-dispersion shifted fiber is used to compensate for the negative dispersion of SDDSF over the entire EDFA bandwidth. The eye opening penalty of dispersion in systems of bitrate as high as 10 Gb/s per channel after 1000 km fiber transmission could still be less than 1 dB. It is a cheaper, more simple and reliable scheme.
