A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The term laser originated as an acronym for light amplification by stimulated emission of radiation.
Fiber Optical Couplers. Fiber optical couplers are used to both split and combine optical signals in optical fibers. As passive optical components, they are often used in data transmission. The broad range of products includes SM, PM, MM, and POF couplers as well as planar splitters. The planar waveguide splitters are a good alternative to multi-channel splitters... Description. Planar waveguide splitters are a good alternative to multi-channel splitters.
