A dense wavelength division multiplexing network, or DWDM network, is a technology for increasing the bandwidth of information sent over fiber optic cable.
Wavelength division multiplexing (WDM) was first used by telecommunications companies to increase the capacity of their networks without needing to run additional cable. WDM technology uses carrier signals sent at different wavelengths, or different colors of laser light, to transmit multiple signals on a single fiber cable, and to enable simultaneous bidirectional communication. While WDM uses eight channels with eight wavelengths, DWDM can pack as many as 160 wavelengths into a single cable by using tighter spacing between wavelengths. Consequently, a DWDM network provides tremendous increases in bandwidth while also enabling greater accuracy over longer runs.
DWDM network solutions are in greater use today as enterprises adopt more data-intensive technologies. From VoIP solutions to videoconferencing and hospitality TV, and from data replication and data center transfers to hybrid WANs and critical large web apps, many enterprise solutions require large volumes of data to be transferred quickly and accurately. By filling this need, DWDM network services have become business-critical IT components.
Spectrum Enterprise offers industry-leading DWDM network technology in Wavelength services for data-intensive transport.
As a leading provider of fiber solutions, Spectrum Enterprise offers a suite of services that help enterprises overcome limitations, integrate critical technologies, and drive competitiveness and innovation to achieve greater business success.
With Wavelengths, Spectrum Enterprise clients get a lit Layer 1 service using a DWDM network with a dedicated “pipe” that allows traffic to pass transparently. Low-latency bandwidth is ensured by the lack of packet/frame routing, and clients can connect geographically diverse locations with dedicated, point-to-point circuits and multi-location networking.
A DWDM network solution from Spectrum Enterprise provides dedicated and secure connectivity between critical locations. Clients can count on the reliability of the Spectrum Enterprise wholly-owned and redundant fiber network, with 230,000 fiber route miles and 191,000 fiber-lit buildings in 32 metro areas and 41 states nationwide. A dedicated Network Operations Center (NOC) provides 24/7/365 monitoring to ensure performance, uptime and availability. With the Spectrum Enterprise DWDM network, cloud applications run more efficiently, large files transfer within seconds, videoconferences have crystal-clear images and audio, and data replication can take place with greater frequency, speed and accuracy.
