Next : Singlemode double window plastic box 1x2 FBT splitter with SC/APC connector, Coupling ratio 50:50
Optical coupler is also called optical splitter, is one of the most important passive devices in optical fiber link, is with multiple inputs and multiple output end of the optical fiber connected devices. The fiber optic splitter by the light splitting principle can be divided into the fused biconical taper (FBT type) and planar waveguidetype (PLC type).
