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.
