DWDMs/WDMs

APA Cables & Networks offers wavelength division multiplexers for expanding the bandwidth of optical communication networks. Wavelength division multiplexers for both singlemode fiber and multimode fiber applications are available. Wavelength multiplexing devices can be provided for coarse wavelength division (20 nm channel spacing), dense wavelength division (100 GHz and 200 GHz channel spacing), and broad wavelength band division (e.g., 1310 nm and 1550 nm). DWDM channels are tuned to the ITU wavelength grid.

In addition to the standard 4, 8, and 16 channel counts, APA Cables & Networks can provide custom fabricated wavelength division multiplexers for any channel count between 2 and 16.

Product Features

WDM components are used at several locations within fiber optic networks.
- At the transmitter end, a WDM is used to combine several wavelengths onto a single mode or multimode fiber for transmission through the communication network.
- At the receiver end, a WDM is used to separate the wavelengths for reading the information transmitted on each channel.
- At points within the network, a WDM is used to add or drop selected wavelengths
