Description
FBT (fused biconical taper) is the traditional technology in which two fibers are placed closely together, typically twisted around each other and fused together by applying heat while the assembly is being elongated and tapered.
Production Introduction
FBT coupler is fused biconic taper coupler, which is a device applicated in optical fiber systems with one or more input fibers and one or several output fibers.
For the fused optical splitter,It can be divided into different ratios.such as 50/50 if the split is even, or 80/20 if 80% of the signal goes to one side and only 20% to the other.
As a result of its great function,Optical splitter is a very important part in passive opitc networks (PON). FTB Fused fiber splitter (coupler) can do Singlemode (1310/1550nm) and Multimode (850nm).Cable diameter can be 0.9mm,2.0mm,3.0mm.
