This fiber-coupled Beam Splitter 1 ⇾ 2 is a compact opto-mechanical unit that splits a fiber-coupled source into 2 output fiber cables with a fixed splitting ratio and a high efficiency. The input port is fiber-coupled to a PM fiber cable. Requests for custom fiber pigtails, different wa 37362 zed light in, through slow axis, Port 2: 50%, ro gh slow axis, Port 1: 100%, Linear polarized light out. Newport's F-PBC Series Polarization Beam Combiner/Splitters can be used to combine light from two PM input fibers into a single SMF-28 output fiber, or to separate the orthogonal polarization components of an input signal between two output fibers.
