Dense wavelength-division multiplexers
These DWDMs are designed for use in optical communications networks that achieve higher system capacity by encoding information on several optical carrier wavelengths. Available in 4-, 8-, and 16-channel configurations, these passive devices can be used at the transmitter end to launch several optical carrier wavelengths into the same singlemode optical fiber for transmission throughout the network. At the receiver end, the DWDMs are used to separate the optical carrier wavelengths and launch each one into a different fiber for transmission to local nodes.
