FBT Couplers

FBT (Fused Biconical Taper) Couplers are fundamental, all-fiber passive components that split, combine, or distribute optical signals between input and output ports. Utilizing a precise fusion and tapering process, they offer reliable performance with customizable splitting ratios, low insertion loss, and high directivity. As a core technology within the broader category of Fiber Optic Splitters, they are widely deployed in passive optical networks (PON), fiber optic sensors, and signal monitoring/tapping points. Their simple, robust, and cost-effective design makes them essential for enabling efficient optical power management and signal routing in various network architectures.
