Overview |
|
|
The DCM LiteTM product is a fixed
chromatic dispersion compensation module designed
to compensate fiber span chromatic dispersion.
Inserting these modules into fiber links allows
for transmission link distances to be increase past transceiver
dispersion limits.
The DCM LiteTM
modules are available with fiber Bragg grating (FBG)
technology or dispersion compensating fiber (DCF)
technology. Both technologies fit into a 1-RMU
19 or 23 inch rack mountable case. |
