1310/1550nm Dual Window Single Mode 1x2 FBT Splitter
1310/1550nm Dual Window Single Mode 1×2 FBT Splitter is a fused biconical taper (FBT) optical coupler designed to divide a single input optical signal into two output ports with a stable and predefined splitting ratio. Operating at both 1310nm and 1550nm transmission windows, it ensures consistent performance across standard single-mode fiber communication systems.
Built using precision FBT fusion technology, the device offers low insertion loss, high return loss, and excellent environmental stability. It maintains reliable optical power distribution with minimal signal distortion, making it suitable for demanding telecom and data transmission environments.
Compatible with SMF-28e single-mode fiber and available in steel tube or ABS box packaging, this splitter is widely used in WDM networks, fiber optic sensing systems, optical amplifiers, and dispersion compensation modules where stable and efficient signal splitting is required.
