  • Optical Fibre Switch
    Publication number: 20080131048
    Abstract: An optical fibre switch (10) includes an optical fibre conduit (12). A transducer (16) is carried on the conduit (12), the transducer (16) converting input energy of one form into mechanical energy so that the application of an external stimulus causes a change in condition of the transducer (16) which imparts that change in condition to the conduit (12). An input energy applying arrangement (20) is arranged on the transducer (16) for applying the external stimulus.
