Product Description

1X2 (2X2) Single Mode Dual Window Fiber FBT Coupler

Description

FBT Coupler is a splitter which based on fused biconical taper technology. It is widely accepted and used in passive optical networks (PON) solution. FBT coupler is a traditional technology that two fibers are typically twisted and fused together while the assembly is being elongated and tapered.
Lightwit Photonics provides a wide breadth of FBT Coupler splitters, including Singlemode Standard Coupler, Dual Window Coupler, Three Window Coupler, Wide Band Coupler, PM Fused Coupler and All Band Coupler with low insertion loss and high performance. These Fused couplers are available with coupling ration ranging from 1:99 to 50:50. Most important, customized specs are also available.
