Optical Networking in the Telecommunications Age

By Dustin Morris

Optical switches are switches that allow both optical fiber signals and integrated optical circuits to be moved from circuits to another

Optical switches can be used for applications requiring high speed positioning up to 3600 rpm. Optical switches for connecting storage networks over long distances are coming to mainstream enterprises this spring.

Optical networking switches are used to disconnect and reroute fiber optic communications. Optical switches separate different wavelength signals and direct them to different ports.

Optical switches are much speedier than regular switches, but also far more pricey. With optical networking switches you are paying for the speed.

Optical switches are often used in fiber optic component testing. In the typical optical network there's a huge need to switch the packets as speedy as possible.

Optical switches exist today, but they have to convert optical beams to electrical current, then convert those back into optical signals.

Optical switches are faster than regular ones but also more expensive. Fast optical switches, such as those using electro-optic or magneto-optic effects, may be used to perform logic operations.

Optical networking is critical to the future of telecommunications, and 40 GBs. The high capacity of the fiber optic. Slow optical switches, such as those using moving fibers, may be used for alternate routing of an optical transmission path, such as routing around a fault.
