Optical fiber splitters can distribute optical signals to multiple target locations, achieving multiplexing of optical signals, saving the amount of optical fibers and cabling costs. Optical splitters are a very important component in fiber optic links, widely used in. An Optical Splitter, also known as a beam splitter, is a passive optical device that divides a single input optical signal into two or more output signals. Conversely, it can also combine multiple signals into one. Its primary role is in Passive Optical Networks (PON), which are the foundation of. Fewer fibers are used on the side of the network feeding the splitter. Addresses are reconfigurable by jumpers in this configuration and the Home Run configuration.
