Singlemode single window, double window, dual window steel tube 1x2 FBT splitter, optical coupler

Singlemode single window, double window, dual window steel tube 1×2 FBT splitter, optical coupler

Optical coupler, also referred to as optical splitter, is an essential passive component in optical fiber links, connecting multiple input and output fiber optic ends. Based on the light splitting principle, optical fiber splitters are divided into two types: fused biconical taper (FBT) and planar waveguide (PLC).
