Brief Introduction

FBT (Fused Biconic Taper) coupler is to bundle two or more optical fibers together, and then melt drawing on the tapering machine, and monitor the change of the splitting ratio in real time. After the splitting ratio reaches the requirements, the melt drawing is ended, and one fiber is retained at one end (the rest Cut off) as the input terminal, the other end as a multi-output terminal. The mature cone drawing process can only pull below 1 × 4 at a time and package in steel tube or ABS box package. There are have different wavelength windows, such as dual windows or three windows.
