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. Although they all belong to the optical distribution and management system, their. Splitter Distribution Box integrates fiber termination, splicing, distribution, and especially PLC optical splitter installation. a laser beam) into two (or sometimes more) beams, which may or may not have the same optical power (radiant flux). Additionally, beamsplitters can be used in reverse to combine two different beams into a single one.
