prev : Singlemode 1310-1550nm plastic box 1x3 FBT coupler with FC/APC connector, Coupling ratio 33:33:33
Next : Singlemode single window, double window, dual window steel tube 1x2 FBT splitter, optical coupler
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).
