  • Optical Splitter Technology and Principles

    Optical Splitter Technology and Principles

    At its core, a fiber optic splitter relies on the principles of light reflection, refraction, and waveguiding to divide signals. They are devices that split an incident light beam into several light beams at certain splitting. Fiber optic splitter, also referred to as optical splitter, fiber splitter or beam splitter, is an integrated waveguide optical power distribution device that can split an incident light beam into two or more light beams, and vice versa, containing multiple input and output ends. The optical network system uses an optical signal coupled to the branch distribution. This capability is crucial in telecommunications, especially in Passive Optical Networks (PONs), where fiber-optic networks must.
