What does DWDM stand for?
- DWDM stands for dense wavelength division multiplexing, a technology that enables multiple data channels to be sent over a single fiber-optic cable.
- DWDM takes advantage of the fact that fiber-optic transmissions are light-based. In each pulse of light, data from up to 80 sources can be combined and transmitted on different wavelengths, vastly increasing bandwidth.
DWDM is a common technology in fiber-optic networks today, enabling organizations to significantly increase the bandwidth available from a single fiber cable. But what does DWDM stand for? And what benefits does it provide an organization? Here’s a short primer on “What does DWDM stand for?” that offers some answers.
What does DWDM stand for?
DWDM stands for dense wavelength division multiplexing, a technology used in fiber-optic networks, which use light to transmit data over thin plastic or glass fibers. DWDM combines multiple data signals on a single fiber cable, encoding each signal on a different wavelength of light. After reaching their destination, signals are detected and separated.
What does DWDM stand for in terms of bandwidth?
A single strand of fiber-optic cable can accommodate as many as 80 channels, each on a different wavelength. Each channel can carry 2.5 Gbps, providing a total bandwidth of 200 billion bits per second for a single fiber strand. With fiber-optic cables typically comprising dozens or hundreds of fiber strands, DWDM allows a single fiber cable to carry multiple terabits of data per second.
What does DWDM stand for vs. WDM?
Wavelength division multiplexing (WDM) is a similar technology to DWDM, but provides only two wavelengths on one fiber.
What does DWDM stand for vs. CWDM?
CWDM, or course wavelength division multiplexing, is another multiplexing technology; it supports 18 wavelength channels.
What does DWDM stand for when it comes to scalability?
DWDM provides nearly unlimited scalability for enterprises as they expand their networks.
What does DWDM stand for in cost reductions?
DWDM helps to reduce the cost of networking by cost-effectively providing increased bandwidth and enabling organizations to avoid the capital investment of a dedicated network.
