Standard DCMs support any wideband signal at any wavelength inside the C-band independently of the ITU-T grid used. A wide range of compensating distances is available to adjust the dispersion compensation to the specific link requirements.
FBG DCMs use Fiber Bragg Grating (FBG) technology to provide reduced insertion loss for specific wavelength configurations. Greater reach and lower cost is achieved than with standard dispersion compensating fiber modules.
