FSM−11/FSM−12 

Many applications in optical measurement systems or data communication networks require distribution and modulation of light, guided in optical fibers. The series FSM-11 (1 input and 1 output channel) and FSM-12 (1 input and 2 output channels) multimode optical fiber switches were developed mainly for applications in the field of spectroscopy.
These systems work with multimode fibers with a core diameter from 50µm up to 600µm. Other fiber parameter can be realized without problems on request.

The switching principles are based on piezoelectric elements providing a fast switching frequency up to 500Hz. The system is very compact, insertion losses are < 0.6dB. All switches of piezosystem jena work without any optical components. Hence there is no dependency on any wavelength.

All switches can be used from UV up to the IR region. Standard switch configuration comes with one meter fiber length on input and output connectors. Bulkhead connectors are also available. The switch can be controlled by TTL signal. An external power supply of 5V DC is necessary.
