Single Mode FBT Splitter

Package Type One: Bare Fiber or 0.9mm Loose Tube
Package Type Two: 2mm Loose Tube

At its most basic, the FBT splitter, short for fused biconical taper splitter, is a passive device that divides an input optical signal into unequal portions, and then send out the divided signals to separate users. FBT technology has become mature after developing for about 20 years. The FBT splitter is now much cheaper to manufacture, and has been widely used in FTTx systems, MANs, WANs, CATV, and active devices.

Single mode FBT splitter from our company has wide bandwidth, suitable for incoming signals with wavelengths ranging from 1,260nm to 1,650nm. This range of fiber optic splitter has a small physical size, available in different packages.

Currently available single mode FBT splitters are 1×2, 2×2, 1×3, and 1×4 types. The product can be tailored to your specific requirements.

Benefits
1. This type of FBT splitter is built to the Telcordia GR-1209-CORE and Telcordia GR-1221-CORE standards. It is interchangeable with many other optical fiber splitters made to the same standards.
2. Low insertion loss
3. High reliability
4. Meet the IEC and RoHS requirements
