Emerging Fiber Optic Data Communication Technologies

With the explosive growth of Internet users, the demand for data communication network bandwidth has increased significantly.By the end of 2000, there were already 29 million Internet domains and still increasing. Digital library, distance learning, e-commerce, video on demand and peer-to-peer sharing all are spawned by those web sites.

The majority of the backbone level connections for the Internet are backed by AT&T, Worldcom and Sprint with a standard speed of 2.5Gbps.

The network infrastructure has serious difficulty in keeping up with the bandwidth requirement and that’s why 10Gbps, 40Gbps and even 100Gbps are being set up and developed by the fiber optic equipment manufacturers. Find more about multi modality imaging via visiting online official websites.

Future Internet applications will create even more demand on the bandwidth and switching capabilities of the network systems. With the inception of Web 2.0, more bandwidth-hungry software which extensively uses graphics, video and images are used.

The Internet backbone has to keep up with this demand. Actually many carriers have already upgraded their network to 10Gbps and 40Gbps. (although, 100Gbps stays under development at this moment).

On the technology side, ATM (Asynchronous Transfer Mode) over SONET have been adopted as the main transport mechanism for broadband traffic. If you want to get more info about Leica microscope, you can click at  http://www.technospex.com/products/uraman-module/.

However, the speed of each fiber cannot be increased indefinitely, once the bandwidth required is greater than can be supported by a single fiber, multiplexing technology is incorporated into the system such as TDM and WDM.

There are lots of promising technologies for fiber optic data communications. But we have to investigate the abilities and limitations of each technology. These technologies comprise All-Optical Network, WDM and Wavelength Routing technologies.
