About Optical Switches
Optical switches are optoelectric devices, consisting of a light source and a detector that produces a switched output or completes a circuit. Optical switches are useful in computer networking because they do not rely on a particular data speed or protocol to process signals. Optical switches can also be used to separate and direct signals at different wavelengths. Electro-optical switches convert the incoming photons to electrons to do the switching action within the switch. Fiber optical switches do not perform this conversion. Instead, a fiber optical switch maintains the signal as light from input through to output.
Optical switches can also be used to switch audio and video inputs. An optical audio switch is used to manage and prioritize audio inputs coming from a variety of interconnected components, such as a DVD player, high-definition television, or computer. A digital optical switch can also manage the inputs of a variety of digital or analog devices, processing both video and audio signals. Optical audio switches and digital audio switches are available from a variety of manufacturers.
