The 2*2 5/95 FBT Coupler is a fused biconical taper optical coupler designed to divide an input optical signal between a high-power branch and a low-power tap branch. With a nominal 95/5 coupling ratio, it is suitable for optical power monitoring, signal sampling, and customized fiber optic assemblies requiring controlled asymmetric power distribution.

The 95% branch carries most of the input optical power and is intended as the main transmission path. The 5% branch extracts a smaller portion of the signal for monitoring, measurement, feedback, or power-detection functions.
Yes. The coupling ratio, fiber length, loose-tube specification, fiber color, package dimensions, and connector configuration can be customized according to the application. This version uses a connector-free configuration with 0.9 mm loose tubes and a 3 * 50 mm package.
