contents introduction contents, introduction technology, types of optical bers & interfaces, ber switches, customized ber switches introduction 1 In 1999 piezosystem jena was introduced as one of the rst companies in the world to provide beroptic switches for multiplexing of optical signals. piezosystem jena developed an unique principal of ber 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 bers. This application is not only for adjusting these components in the laboratory; it can also be used to create special products in the elds of optical communication, optical data storage, spectroscopy, and metrology. Typical designs are: 1 x N switches for multimode bers for optical measurements (especially spectroscopy) and multi-point sensor systems Custom made solutions (for example 2 by 2 or 2 by 9 congurations) Optical ber switches using direct piezo electrical movement...

technology contents, introduction technology, types of optical bers & interfaces, ber switches, customized ber switches Multimode switches – the switching principle by direct ber movement The best way for switching optical bers is the direct movement of the optical ber 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 inuences of hysteresis and creep on the accuracy of such a switch, the actuator end positions can be xed by special stopping congurations. In the case...

3 types of optical bers & interfaces Types of optical bers Optical bers are mainly classied with respect to the lateral dimensions of the lightguiding region, the so-called ber core. The core diameter together with the refractive index distribution of the core-cladding assembly determines the number of modes the ber carries. The following gure [Fig. 4] and table give a rough overview on the different ber types. index prole index prole index prole index prole part no.for ber (without optical connector) * NA – numerical aperture ** when ordering please use the sufx: ST: -10, SMA: -20, FC/PC:...

The typical insertion loss of an SMA connector is greater than 1 dB. sufx for ordering: –20 FC/APC – The Angle FC (APC) polish, adds an 8 degree angle to the connector endface; equipped with an...
