10 Leading FBT Coupler Manufacturers in the world 2025

Introduction to FBT Coupler

Fused Biconical Taper (FBT) couplers are essential passive optical components in optical communication systems. They operate based on the principle of fusing and tapering multiple optical fibers together. When the fibers are heated and stretched, the evanescent fields of the light in the fibers interact, allowing the light to be split or combined between the fibers.

FBT couplers are widely used in various applications such as local area networks (LANs), fiber - to - the - home (FTTH) networks, and optical test equipment. They offer several advantages, including low insertion loss, high directivity, and good environmental stability. Their simple structure and relatively low cost make them a popular choice for many optical communication scenarios.
