CS-HLDC High Level Dispersion Compensator

The ClearSpectrum™-HLDC is a static chromatic dispersion compensation module for coherent communication ultra long-haul networks. This 1U half-rack module is specially designed to compensate a large amount of dispersion while maintaining a very low insertion loss. TeraXion’s well-established technology in Fiber Bragg Grating (FBG) translates into a reliable and compact solution based on a cascade of several Telcordia qualified gratings. This RoHS compliant solution offers a wide 50 GHz operation bandwidth regardless of the level of dispersion making it perfectly suited for substantial dispersion compensation of 40 and 100 Gb/s coherent detection links.


  • 150 000 ps/nm in a 1U half-rack
  • Ultra-low insertion loss & latency
  • No fast SOP change
  • RoHS compliant
