FBT (Fused Biconical Taper) fiber optic splitter for cost-effective signal splitting in single mode networks. Available in 1x2 and 2x2 configurations with steel tube and ABS box packages. 10-year warranty with stable performance across -40°C to +85°C operating range. They operate over the full standard single mode range of wavelengths (1260-1650nm) and are available in 1×2 and 2×2. FBT splitter, called fused biconical taper splitter, uses a high-temperature fusion splicer to fuse two or more fibers into one to split optical signals. It is a traditional technology based on optical fiber, involving the fusion of several fibers from the side of each fiber.
