In today's rapidly evolving optical communication landscape, fiber optic splitters play a vital role in Passive Optical Networks (PON), widely used in FTTH (Fiber to the Home), data centers, laboratories, and even university research 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. Fiber optic splitter, also referred to as optical splitter, fiber splitter or PLC splitter, is an integrated waveguide optical power distribution device that can split an incident light beam. A PLC splitter (Planar Lightwave Circuit Splitter) is an essential passive component in fiber optic networks.
