Dense Wavelength Division Multiplexing (DWDM) Performance and Conformance Testing

Dense wavelength division multiplexing (DWDM) is a technology that uses multiple lasers to transmit many wavelengths of light simultaneously over a single optical fiber. Each signal is modulated by different source data (text, voice, video, etc.) and travels within its own unique color band (wavelength). DWDM enables the existing fiber infrastructure of the telephone companies and other carriers to be dramatically increased. Vendors have...
