DENSE WDM IN THE 1310NM BAND

摘要

Dense wavelength division multiplexing within a 1310nm band is accomplished over a single mode fiber. Carrier wavelengths are selected from within two windows, a low subband (140) and/or a high subband (160), on either side of a guardband (120). The guardband includes the zero dispersion wavelength of a single mode fiber in the optical communication link and separates low subband and high subband within the 1310nm band. Dispersion compensation is provided for carrier signals in each dense WDM channel in the low and high subbands.
