FBT Splitter (Fused Biconical Taper) 1X3 – 1XN LC/UPC SM & MM

Description:

Bwnfiber FBT Splitters (Fused Biconical Taper) are available in a wide range of configurations, including 1×2, 1×3, 1×4, 1×5, 1×6, 1×8, 1×12, 1×16, 1×18, 1×20, and 1×24, catering to both single mode and multimode fiber applications. We offer pre-connectorized options with various connector types such as SC, FC, ST, LC, and E2000, ensuring compatibility with your specific needs.

The 1×3 Singlemode Single Window 3.0mm Loose Tube Fiber coupler is designed to split optical signals into three parts, and the coupling ratio can be customized according to your requirements, providing flexibility in signal distribution.

FBT Splitters play a crucial role in GPON FTTx networks and can be installed in the Central Office or distribution points, whether indoor or outdoor. They offer exceptional stability for multiport optical signal splitting with low insertion loss. FBT couplers are specifically designed for power splitting and tapping applications in telecommunication equipment, CATV networks, and test equipment.

We also offer no-connector FBT options, allowing for easy installation in fiber splice closures or fiber distribution boxes, saving space. These FBT Splitters are ideal for GPON, FTTH/FTTx applications.

 Features:

• Low insertion loss
• Low polarization dependent loss
• High Return Loss
• Optional Split Ratio 20/80, 40/60…(50/50 as default.)
