摘要

The performances of dense 10 Gb s~(-1) time-division multiplexing (TDM) and wavelength-division multiplexing (WDM) signals (Δλ = 0.2 nm) are analyzed comparatively for transmission in single-mode fibers (SMFs) and in non-zero dispersion-shifted fibers (NZDSFs). In the ultrahigh capacity and ultralong haul communications, the TDM format is superior to WDM when dispersion is precisely compensated (including third-order dispersion compensation). As far as the dispersion compensation is concerned, fiber Bragg gratings (FBGs) are more advantageous than dispersion compensation fibers (DCFs) in SMFs. But in NZDSFs, when the distance is shorter than 2000 km, the difference between adopting FBGs and DCFs is not distinct, and with the distance further increasing, DCFs retain their superiority even though the group dispersion ripples of FBGs are ignored.
