Thorlabs' Terminating Fiber Light Trap Connectors are designed to be used with ports that do not have an output fiber connected to them. Terminating connectors reduce back reflections into the input fiber by up to 50 dB by coupling emitted light into HPSC25 fiber and then diffusing the light within the terminator. In contrast, typical back reflections from an unused port can be as poor as 20 dB. Our terminators are for use with light from 400- 2100 nm, and have FC/PC or FC/APC 2.0 mm narrow key connectors. For other connector styles, please contact Technical Support.

The image on the right shows an FTPC1 fiber optic terminator being used to convert a 2 x 2 SM fiber coupler into a 1 x 2 coupler. Here, the FTFC1 is connected to the coupler using an ADAFC1 mating sleeve. Thorlabs offers a range of 2 x 2 SM, 1 x 2 PM, and 1 x 2 MM fiber optic couplers.
