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.
