Cassette-Type Coarse Wavelength Division Multiplexer
Pictures and Schematic Diagram
Choose a coarse wavelength division multiplexer to extend the reach of your light-wave signals! At its most basics, the coarse wavelength division multiplexing is a type of optical wavelength management device that is based on proven thin-film filter technology. This selection of fiber optic components provides a reliable means of transport that conveys multiple colors of light at the same time over a single optical fiber.
The increasing popularity of CWDM in multi-wavelength digital transport architectures is due to the fact that the multiplexing unit enables the use of very low cost un-cooled DFB laser transmitters. Besides, CWDM falls into the category of passive optical components, which means it does not rely on any electric power to operate.
