Piezoelectric actuators can be used to move microoptical components, such as optical fibers and microprisms of these components. This application is not only for laboratory adjustment of these components, but also for the creation of special products in the field of optical communication, optical data storage and metrology. On the base of the combination of piezoelectric actuators with different microoptical components piezosystem jena has already developed a broad spectrum of systems for different applications : 1 x N switches for singlemode fibers for optical communication, data storage, optical...

For all applications of optical fibers, switching plays an important role. In optical communication or data storage, the signals coming from one transceiver have to be directed to one of a number of receivers. In optical spectroscopy the information from different probes must be given to the spectrometer head in a time multiplexed way. Finally a switchable high power beam delivery system can switch the light tool between a number of working stations and thus increase system flexibility and cost. There are several key parameters for fiber optic switches that are common for all the applications...

The best way for the switching optical fibers is the direct movement of the optical fibers with respect to each other. Piezoelectric actuators are ideal candidates for this purpose due to their typical movement ranges and actuation speed. In order to exclude the influences of hysteresis and creep on the accuracy of such a switch, the actuator end positions can be fixed by special stopping configurations. In the case of multimode fibers, the required accuracy (10 microns or more depending on the fiber core diameter) can be achieved by different approaches of precision engineering. For singlemode...

Casing and interface for Multiplexer and Multimode switches A variety of casings can be offered for piezosystem jena switches. Depending on customer requirements, plug-in casings are available as well as screw slot casings and special custom size rack mount casings. The casing not only protects the mounted fiber, its also the basis for easy integration of this part into your existing system. > Casing in standard version housing l/w/h part.-no.

Optical fibers are mainly classified with respect to the lateral dimensions of the light-guiding region, the so-called fiber core. The core diameter together with the refractive index distribution of the core- cladding assembly determines the number of modes the fiber carries. The following figure and table give a rough overview on the different fiber types and their main application fields. > SMA Due to its stainless steel structure and low-precision, threaded fiber locking mechanism, this connector is used mainly in applications requiring the coupling of high-power laser beams into large-core,...
