Multi-mode plastic box 2×4 FBT 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).
