Dense Wavelength Division Multiplexing

The business benefits of dense wavelength division multiplexing.

Dense wavelength division multiplexing (DWDM) is a technology developed for fiber optic communications that enables a single strand of fiber cable to transmit data at a higher bandwidth.

Basic or coarse Wavelength division multiplexing (WDM) was initially developed in the 1970s and was popular with telecommunications companies that used this new technology to expand the capacity of their networks without needing to lay additional fiber cable. By transmitting carrier signals at different wavelengths or colors of laser light, WDM technology could multiply the number of signals being sent simultaneously, thus increasing bandwidth and allowing signal to be sent in both directions on the same cable.

Dense wavelength division multiplexing uses tighter wavelengths to pack even more bandwidth into a single cable fiber. While WDM provides eight channels with eight wavelengths, a DWDM network can accommodate up to 160 wavelengths per cable. With this increased bandwidth, dense wavelength division multiplexing is well-suited for data-intensive applications and systems such as VoIP business phone service, digital video transfer, data replication, data center transfers, Hybrid WANs and critical large web apps.

For organizations seeking an industry-leading dense wavelength division multiplexing provider, Spectrum Enterprise offers data-intensive transport in its Wavelength services.
