FBT (Fused Biconical Taper) Splitter, also known as fiber optic coupler, is a device that realizes the distribution or combination of optical power among different optical fibers. It could split the optical power transmitted in one fiber into multiple fibers by a certain coupling ratio, or combine the optical power transmitted in two or more fibers into one fiber.

For example, when a fiber optic light beam is transmitted through the 1x2 20/80 Single Mode FBT Splitter, it will be divided into 2 beams, one of which is 80% of the original source and another is 20%. 

The FBT Splitters are designed for power distribution and tapping in optical fiber amplifier, online monitoring system, PON (passive optical network), OCT medical imaging and CATV solution.
