The Planar Waveguide Circuit splitter (PLC Splitter) divides one or two beams of light evenly into multiple beams or combines multiple beams of light into one or two beams. Its high splitting ratio of 1×64 provides a low-cost, high-stability, and reliable light distribution solution. It is one of the core components in Passive Optical Networks (PON) and is widely used in FTTx deployments, where a single fiber connection. A fiber-optic splitter, also known as a beam splitter, is based on a quartz substrate of an integrated waveguide optical power distribution device, similar to a coaxial cable transmission system. Its basic function lies in the even distribution or combination of optical signals with minimal loss and high reliability.
