What is the WDM fiber network?

light channel WDM optical fiber is divided into several independent channels of different wavelengths to transmit data over a single fiber. It provides enormous bandwidth by multiplying the channels on a single optical fiber, which in turn increase the transmission capacity.

Another cutting-edge technology to enable high-speed data transmission, WDM fiber optic wavelength division multiplexing fiber-optic network multiplied by the speed of data transmission using multiple channels of lightin a single optical fiber. The WDM optical fiber network using the enormous bandwidth multiplexing of different channels over a single fiber, thus multiplying the transmission power of the fiber.

For example, if we are to do some work yourself, do some time, but when so many others, help us with our work to be done at the same time a greater amount of work ahead. Even in a WDM fiber network instead of light signals transmitted through a single channel in a single opticalThe fiber is broken, the light channel into multiple channels for a larger and faster transmission of signals. These channels are all different wavelengths at different frequencies. This network uses non-overlapping frequencies of different wavelengths. Each wavelength supports a specific communication channel and transmits the data, what speed you need. Therefore, using multiple channels in a single optical fiber, broadband fiber can be used, resulting in massData transmission over long distances in less time.

The basic principle of WDM fiber-optic network is a channel of light in different wavelengths discrete split. Each wavelength as an independent channel can transmit data at a rate as 2.5 Gbit / s transmission at 10 Gb / s to 100 Gbit themselves say / s. Each channel to transmit data at 10 Gb / s, when a total of 16 channels into a single optical fiber, we received a total of 160Gbit / s data transfer rate over a single fiber. And if a fiberLWL has to say to 48 optical fibers, each fiber at a speed of 160Gbit / s, 48 fibers would give a speed of 7680Gbit / s over a single fiber optic cable. can independent channels with faster data transfer speeds much higher. In addition to the availability of fiber optics to spread 64 or more channels or wavelengths of light, the speed of communication have been given a new dimension. This technology not only increases the speed of data transmission, but also the volumedata transfer, making it an ideal platform for building Internet backbones.

The best advantage of WDM fiber-optic network, is that although it has increased drastically reduced the capacity of a fiber, the cost of fiber optic cable and equipment usage. Another important factor is that, as the network requires negligible maintenance. WDM optical fiber network does not require fiber to be replaced frequently after installation and then at higher levels simply by updatingChanging terminals. The use of this network has led to a huge explosion in transmission capacity in the whole world is revolutionizing communications out.
