Abstract
Dense wavelength division multiplexing within a 1310 nm band is accomplished over a single mode fiber. Carrier wavelengths are selected from within two windows, a low subband and/or a high subband, on either side of a guardband. The guardband includes the zero dispersion wavelength .lambda..sub.0 of a single-mode fiber in the optical communication link and separates low subband and high subband within the 1310 nm band. Dispersion compensation is provided for carrier signals in each dense WDM channel in the low and high subbands.
