No Connectors MxN Single Mode Steel Tube FBT Couplers Splitters
Optic Coupler Brief Introduces:
The FBT optical splitter bundles two or more fibers together, and
then melts and stretches them on a taper, and monitors the change
of the split ratio in real-time. After the split ratio reaches the
requirement, the melt stretch is completed, and one end of the
fiber is retained. (the rest is cut off) as the input, and the
other end is used as the multi-output.
Fused fibers are very fragile, they are protected by a glass tube
made of epoxy and silica powder. Then a stainless steel tube covers
the inner glass tube and is sealed by silicon.
