1310/1490/1550nm Three Window Single Mode 1x2 FBT Splitter
1310/1490/1550nm Three 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 controlled power ratio. Supporting three transmission windows at 1310nm, 1490nm, and 1550nm, it ensures broad compatibility with modern single-mode fiber communication systems.
Manufactured using precision FBT fusion technology, this device delivers low insertion loss, high return loss, and excellent environmental stability, ensuring consistent optical performance even under demanding network conditions. Its compact structure and flexible packaging options (steel tube or ABS box) make it suitable for dense and high-reliability deployments.
This splitter is widely applied in WDM systems, FTTH networks, fiber optic sensing, optical amplifiers, and dispersion compensation applications, where multi-wavelength signal distribution and stable optical performance are required.
