3×3 1310nm PM Fused Coupler F-tone's Fused couplers are used to split optical signals between two fibers, or to combine optical signals from two fibers into one fiber. They are constructed by fusing and tapering two fibers together. F-tone's fused couplers are available in a range of wavelengths, fiber sizes, and splitting ratios. The fiber ends can be terminated with a variety of fiber connectors. Standard configurations are 1×2 and 2×2 couplers. N by M fused couplers, such as 1×3, or 1×4,etc., are also available on request.
