Polarization Maintaining (PM) Fused Couplers
Phoenix polarization maintaining fused couplers are made by fusing and tapering two fibers together. The optical signal directed through the input fiber will be split into two at the fusion point. Phoenix can offer a variety of split ratios (with tap ratios from 1% to 50%). The couplers are available in 1x2 and 2x2 configurations.
