Coarse Wavelength Division Multiplexing (CWDM)
Using the CWDM optics, the multi-rate line cards can be integrated into a
Radiance CWDM system, in which a single fiber pair carries data bidirectionally
on multiple wavelengths. In the following examples, each colored line repre-
sents a different wavelength. The network connections are shown in gray with
the magnification circles displaying the wavelengths carried on the lines.
Connections to the end user are shown in dark gray.
