FBT Splitter: How Much Do You Know?

Date: 2023-02-09 10:24:00

FBT Splitter is responsible to distribute optical signals from central office  to multiple premise locations. This article will provide some knowledge about FBT splitters. 

What is FBT Splitter?
A fused biconical taper (FBT) splitter is based on traditional technology to weld several fibers together from the side of the fiber. Fibers are aligned by heating for a specific location and length. Because the fused fibers are very fragile, they are protected by a glass tube made of epoxy and silica powder. And then a stainless steel tube covers the inner glass tube and is sealed by silicon.


FBT Splitter Types
FBT splitter is available in the market in steel tube, ABS box, and multi-channel box types. The steel tube type is a 1x2 FBT splitter with a different coupling ratio, has 900um loose tube protection, and is provided with a selection of connectors (SC/LC/FC, etc). The ABS box type is a 1x2 FBT splitter module packed in an ABS box with ruggedized fiber jackets of 2mm and up to 3mm with SC/APC fiber connectors terminated. Multi-channel box type like 1x3 FBT splitter has 1x3 single mode single window 3.0mm loose tube fiber coupler that can split the optical signals into 3 parts, and the coupling ratio can be customized.


Features and Benefits
FBT splitter provides high stability, high reliability, low insertion loss, low polarization dependent loss, wide operation wavelength, wide operation temperature, compact size, low cost, easy-to-produce, and customizable splitter ratios.

FBT Splitter is used in an optical communication system, online monitoring system, telecommunication, data centers, FTTx, FTTH, PON, LAN, WAN, CATV, EDFA, local loop, testing equipment, fiber sensors, etc.


To sum up, the FBT  splitter is widely used on fiber in different places on PON systems. Low cost and high reliability and high stability are the main features.  Sun Telecom specializes in providing one-stop total fiber optic solutions for all fiber optic application industries worldwide.
