FBG-DCM ( Fiber Bragg Gratings DCM ) is a compact chromatic dispersion compensator that features both low insertion loss and the lowest latency on the market.
The channelized nature of the fiber Bragg gratings used in the DCML prevents interchannel and intrachannel nonlinear impairments such as self-phase modulation and four-wave mixing crosstalk. These features enable the DCML to handle high optical input power, giving it the flexibility to be used as a pre-compensator before the fiber link or as a post-compensator at the receiver end.
The FBG-DCM provides full C-band coverage on either a 50 or 100GHz grid, addressing up to 9 channels with a single device on the 50GHz grid. All of this performance is packed inside a passive environmentally rugged package that operates reliably even outside the plant.
