Many applications in optical measurement systems, or data communication networks, require distribution and modulation of light, guided in optical fibers. The FSM-1by1 series (1 input and 1 output channel) and FSM-1by2 series (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 ranging from 50 µm up to 600 µm. Other fiber parameters can be realized without problems upon request.
The switching principles are based on piezoelectric elements providing a fast switching frequency of up to 500 Hz. The system is very compact, with insertion losses under 0.7dB. All switches from 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 7-12 V DC or 7-9 V AC is necessary.
