A fiber optic splitter, is a passive device use in telecommunication networks. Unlike active devices (which require power), splitters operate without electricity, relying solely on the physics of. 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. The optical network system uses an optical signal coupled to the branch distribution. This type of device plays an important role in passive. A “splitter” is a power splitter. Rarely, there can be two inputs to provide potential redundancy of route.
