Do you know what is a fiber optic switch?

2022-03-30
The fiber optic switch is a non-contact circuit switch composed of a light-emitting tube, a fiber optic probe, a photodetector, an amplifier and an output indicator light. The fiber optic probe consists of a sending fiber and a receiving fiber, with a certain detection space between them. , use the optical path to switch on or off in the detection space, and realize the circuit switching function through photoelectric conversion. It is used as a circuit switch for various automatic control equipment.

Optical fiber is an abbreviation for optical fiber. An optical fiber is a coated, transparent filament, usually consisting of a core (glass) plus a coating (glass). The diameter of the core material of the optical fiber is between several microns and tens of microns, and the outer diameter of the coating is in the order of 0.1 to 0.2 mm.

Optical fiber switch is a device that can switch optical fiber lines. According to the number of incoming and outgoing lines, it can be divided into 1×2, 2×4 and other switches. When switching, the position of the movable fiber is changed by electromagnetic induction. Switchover times can be as small as milliseconds. It is widely used in optical fiber communication systems to provide switching of backup lines.
