Optical splitters enable a signal on an optical fiber to be distributed among two or more fibers. Since fiber splitters contain no electronics nor require power, they are an integral component and widely used in most fiber-optic networks. A fiber optic splitter is a passive optical component that divides a single incoming optical signal into two or more outgoing signals, or combines multiple incoming signals into one. Unlike active devices (which require power), splitters operate without electricity, relying solely on the physics of. Optical cables, also known as fiber optic cables, consist of thin strands of glass or plastic fibers surrounded by a protective casing.
