1490/1550nm Dual Window Single Mode 1x2 FBT Splitter
1490/1550nm 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 ports with a stable and predefined power ratio. It operates efficiently at both 1490nm and 1550nm dual transmission windows, ensuring reliable performance in single-mode fiber networks.
Built on mature FBT technology, the device delivers low insertion loss, high return loss, and excellent environmental stability, enabling consistent optical power distribution with minimal signal distortion. Its compact design and flexible packaging options (steel tube or ABS box) make it suitable for dense and high-reliability deployments.
This splitter is widely used in WDM systems, fiber optic sensing, optical amplifiers, and dispersion compensation applications, where stable signal division and low loss performance are critical.
