1310/1490nm Dual Window Single Mode 1x2 FBT Splitter
1310/1490nm Dual Window Single Mode 1×2 FBT Splitter is a fused biconical taper (FBT) optical coupler designed to split a single input optical signal into two output channels with a stable and defined splitting ratio. Operating in dual transmission windows of 1310nm and 1490nm, it provides reliable performance for modern single-mode fiber communication systems.
Based on proven FBT manufacturing technology, this splitter features low insertion loss, high return loss, and excellent environmental stability. It ensures consistent optical power distribution with minimal signal degradation, making it suitable for demanding telecom and data network applications.
With SMF-28e fiber compatibility and compact packaging options (steel tube or ABS box), the device is widely used in WDM systems, fiber optic sensing networks, optical amplifiers, and dispersion compensation modules.
