contents introduction contents, introduction technology, types of optical fibers & interfaces, fiber switches, customized fiber switches introduction 1 In 1999 piezosystem jena was introduced as one of the first companies in the world to provide fiberoptic switches for multiplexing of optical signals. piezosystem jena developed an unique principal of fiber surface coupling. The major advantage of this principal is the wavelength independence of the switch due to the fact that no optical components inside the switch are necessary. Furthermore the switching procedure is done by piezoelectric elements...

2 technology Piezo electrically driven optical switches Piezoelectric actuators are well suited to move optical fibers. This application is not only for adjusting these components in the laboratory; it can also be used to create special products in the fields of optical communication, optical data storage, spectroscopy, and metrology. Typical designs are: 1 x N switches for multimode fibers for optical measurements (especially spectroscopy) and multi-point sensor systems Custom made solutions (for example 2 by 2 or 2 by 9 configurations) Optical fiber switches using direct piezo electrical movement...

technology contents, introduction technology, types of optical fibers & interfaces, fiber switches, customized fiber switches Multimode switches – the switching principle by direct fiber movement The best way for switching optical fibers is the direct movement of the optical fiber ends 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...

Types of optical fibers 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 [Fig. 4] and table give a rough overview on the different fiber types. index profile index profile NA - numerical aperture when ordering please use the suffix: ST: -10, SMA: -20, FC/PC: -30, FC/APC: -50, E2000: -60 All fibers can be provided with anti-reflection option after request....
