Piezoelectric driven switches are especially designed for fast switching – measured in milliseconds – low loss and high repeatability. Piezo actuators enable the optical switch to couple optical fibers with an accuracy of a few microns.  The high accuracy of positioning of the piezo-electric actuators guarantees a light transmission of >80%.

Standard switch configurations range from 1-input to 2-outputs, up to 1-input to 9-outputs. Fiber switches can also be used the other way around,from 2-inputs to 1-output, up to 9-inputs to 1-output. Standard fiber diameters range from 50 to 600 micrometers. A variety of connectors are available.

piezosystem jena fiber switches use fiber surface coupling. The major advantage of this design is that it is not necessary to depend on optical components in the switcher. Fiber switches with optical components, like lenses or prisms, will always result in a wavelength-dependent limitation.

The small size of the fiber switch and the easy control make these fiber optic switches ideally suited for use as components of spectrometers or other metrology devices. Switch systems with many more output channels can be achieved by cascading multiple fiber switches.
