Description
Single mode,1x2 Fused Coupler
Optical Fused Coupler is to bundle two or more fibers together,then melt and stretch on the tapering machine,and monitor the change of the spectral ratio in real time. After the spectral ratio meets the requirements,the end of the melting and stretch is finished,one end of which keeps a fiber (cut off the rest) as the input end,and the other end is used as the multiple output end.
