Chromatic dispersion limitations due to semiconductor laser chirping in conventional and dispersion-shifted single-mode fiber systems.

The effect of dynamic linewidth broadening due to frequency chirping in directly modulated single-mode lasers, combined with dispersive single-mode fibers, has been investigated using computer simulation. It has been found that dispersion-shifted fibers have a potential advantage over conventional single-mode fibers for dual-window multigigabit-per-second bidirectional and wavelength-division-multiplexed transmission systems.
