Description:
Fused biconical taper (FBT) technology is tied to two or more fibers, and then melted in a cone machine, pull tensile and real-time monitoring of changes in splitting ratio, melt tensile splitting ratio to meet the requirements end, wherein one end of a fiber optic reserved ( The remaining cut off) as the input terminal and the other end a multitude of road outputs.
fused fibers are very fragile, they are protected by a glass tube made of epoxy and silica powder. Then a stainlesssteel tube covers the inner glass tube and is sealed by silicon. FBT splitter with ABS box is also widely used for different applications.
Features:
Low insertion loss, low PDL
High credibility and stability
Industry standard and custom housing available
Various coupling ratio and connector available
Application:
Optical communication system
CATV System
System and signal monitoring
Fiber to the home (FTTH)
