A fiber splitter is a device intended to split an input optical signal into two or more output signals. They are sometimes referred to as optical splitters or beam splitters. Utilizing technologies such as planar lightwave circuit (PLC) technology and fused biconical tapering, this division is completed. The numbers 1x2, 1x4, 1x8, and 1x16, which indicate the number of input ports and the number of output ports, respectively, are the most popular varieties of fiber splitters.
