No Reflection Termination

Fibrain No Reflection Termination can be used when an extremely low reflection (the smallest possible percentage of returning signal) at the end of a fiber optic link is necessary, e.g. in specialty OTDR, BOTDR, and BOTDA (such as in SHM - Structual Health Monitoring) measurements or in measuring devices calibration. The No Reflection Terminations are characterized by uniform return loss in the whole CWDM wavelength range. They are based on various fiber types (G.652.D, G.657.A2, etc.) and are available as a pigtail for splicing or as a patchcord on special request. Their length and connectors are chosen based on customer’s order.


  • 1250 nm - 1650 nm operating range
  • Available as a pigtail or patchcord with any connector
  • Return loss > 70 dB
  • Each NRT is measured individually
