Fiber Optic Switch
Definition - What does Fiber Optic Switch mean?
In computer networking and communications, a fiber optic switch refers to any piece of circuit switching equipment placed between fibers; hence, it refers not only to a networking switch used in fiber optic networking but also to a small device attached between lines in order to make light signals follow one path or another, like a selector switch.
Techopedia explains Fiber Optic Switch
Other types of fiber optic switches are literally switches, as in a light switch, which uses fiber optic cables to deliver signals instead of traditional copper wires. This is because some environments are corrosive or have so much electromagnetic interference that traditional copper or any kind of metal wiring is not suitable for transmitting signals.
