Abstract
Apparatus for selectably positioning an optical fiber end along a range of positions comprising a bender assembly including at least one piezoelectric bender element and having a first end thereof arranged for association with one or more optical fiber ends and a second end thereof located at a reference position. Suitable application of electrical energy to the piezoelectric bender element causes it to assume a selected position along the range of positions. Various embodiments of bender assemblies and applications thereof in communication are also described.
Claims21
A communications exchange comprising:
- a first plurality of electromagnetic radiation transmitting units each of which provides a beam of information bearing electromagnetic radiation;
- a second plurality of electromagnetic radiation receiving units arranged in radiation receiving relationship with said first plurality, each receiving unit being arranged to receive radiation from said first plurality of electromagnetic radiation transmitters;
- means for causing the radiation from any selectable one of said transmitting units to be received by any selectable one of said receiving units for establishment of communications therebetween, said means for causing comprising at least one device for selectably orienting an end of an information bearing optical fiber.
