High Reflection Termination

Fibrain High Reflection Patchcords are characterized by uniform high return loss in the whole CWDM wavelength range. Their function is to reflect as much light as possible, which is required in some polarization mode dispersion measurement schemes. They are polarization independent passive components. Each patchcord is delivered with a test report. The patchcords are based on various fiber types (G.652.D, G.657.A2, multimode, special fibers, etc.) and their length and connectors are chosen based on customer’s order. Detailed selection of the manufacturing components ensures the highest quality of the connectors.


  • 1250 nm - 1650 nm operating range
  • Available as a patchcord with any connector
  • Return loss < 1 dB
  • Each HRT is measured individually
