What is plc optical splitter
Feb 21, 2023| What is PLC Optical Splitter?
Optical fiber splitter is a device used to realize the splitting and combining of light wave energy. It distributes the optical energy transmitted in one optical fiber to two or more optical fibers according to a predetermined ratio, or synthesizes the optical energy transmitted in multiple optical fibers into one optical fiber.
According to the principle, the optical splitter can be divided into two types: the fusion tapered type and the planar waveguide type. The fusion tapered type product is made by welding two or more optical fibers on the side; the planar waveguide type is a micro-optical element type product. Photolithography technology forms optical waveguides on dielectric or semiconductor substrates to realize branch distribution functions. The two types of light splitting principles are similar. They achieve different sizes of branches by changing the evanescent field mutual coupling (coupling degree, coupling length) between fibers and changing the fiber radius. Conversely, multiple optical signals can be combined into one signal. called a synthesizer. Fused taper fiber coupler has become the mainstream manufacturing technology in the market because of its simple manufacturing method, low price, easy connection with external optical fiber, and the advantages of being resistant to mechanical vibration and temperature changes.
