3×3(4×4) Monolithic Single Mode Coupler

3×3(4×4) Monolithic Single Mode Coupler

Fiber Optic 3x3(4x4) Monolithic Single Mode Coupler is fabricated by fusing and stretching 3 or 4 fibers under heat at the same time. This fusion technology can avoid applying glue on fibers, which enables FBT couplers to have high environmental stability and very low insertion loss.
