WAVELENGTH DIVISION MULTIPLEXER FOR OTPCIAL TELECOMMUNICATION

摘要

A photosynthesis splitter that can be used for optical communication is disclosed. A photosynthesis splitter is a device required to simultaneously transmit or receive two optical signals of different wavelengths through a single optical fiber.;The photosynthetic spectrometer, which requires precision, has a complicated structure because it uses a plurality of lenses, and assembly is not easy with respect to alignment of the optical axis.;Such structural complexity and assembly and alignment problems can be greatly improved and efficiency can be improved by reducing the number of lenses, the number of parts, and attaching a filter to the lens holder.;Such an optical splitter may be used for transmission or reception equipment for optical communication.
