| 1X2 Coupler |
The Optical Fiber Splitters and Couplers are an optical fiber device capable of branching an optical power on a single optical fiber into two in a designated ratio or combining the optical powers on two optical fibers into one. WFT’s Optical Fiber Coupler range is fabricated by the fuse-taper method allowing a variety of fiber coupler components to be realized. |
