Abstract: A ferrule for an optical fiber connector having open fiber clamping grooves. The ferrule has a body having a plurality of open grooves for clamping the terminating end sections of optical fibers. At least a section of the longitudinal opening of the groove is provided with opposing lips to provide a clamping effect. The width of the longitudinal opening defined between the lips along at least a section of the grooves is narrower than the diameter of the optical fibers to create a tight fit. The grooves and the width of the longitudinal groove openings are shaped and sized to retain the fibers without any clearance to allow for movement of the fiber relative to the groove. Similar grooves may be provided in the ferrule body for alignment guide pins. The grooves are precision formed by high throughput processes, such as stamping and extrusion.

Abstract: There is disclosed a fiber optic coupler for use in single strand fiber systems comprising a device to allow optical access to a single fiber by means of a second fiber which has been attached to it by fusing the glass cladding of the two fibers as by application of heat by a laser. The resulting access coupler provides for coupling both into and out of a single strand of fiber optic waveguide. That is to say, an input optical signal to one single fiber strand can be read out at more than one point on the single fiber or more than one input can be read out at a single point. The coupler is sufficiently low loss to make control systems utilizing single fiber lines rather than bundles a realistic possibility.

Abstract: Axial tension is applied to an optical fiber that had been scored at the intended cleave location, wherein the axial tension is applied in a time-varying manner to maintain the stress intensity factor for crack on the fiber within an acceptable level to produce a stable crack growth at a reasonable rate to cleave the fiber without requiring polishing of the end surface. Careful control of the applied tension force with time acts to control the velocity of the propagating crack by maintaining substantially constant stress intensity factor. The applied axial tension force is reduced with time and/or crack growth (as crack propagates). As a result, the strain energy in the fiber material is released by formation of a single plane with an optical quality surface without requiring polishing. A substantially flat optical surface of enhanced optical quality is formed at the cleaved end of the optical fiber.

Abstract: A system for remote measurement of structural forces includes a plurality of microbend transducers mounted along the length of the structure for microbending an optical fiber in response to structural forces, such as stress acting upon an oil or gas pipeline or the like. An optical time domain reflectometer (OTDR) has a light source for launching a pulsed optical signal for passage through the fiber and a photodetector for sensing as a function of time the intensity of backscattered light reflected back through the fiber, wherein this sensed time function is correlated directly with discrete longitudinal positions along the length of the fiber and the structure. When one or more of the microband transducers is activated to induce a microbend in the fiber in response to localized forces acting upon the structure, a portion of the backscattered light is lost at the microbend. This attenuation in backscattered light intensity is sensed quantitatively and positionally identified by the photodetector. Specific preferred constructions for microbend transducers and system arrangements particularly adapted for detecting structural strain in an oil or gas pipeline are disclosed.

Abstract: Apparatus is provided comprising a laser source, collimating optics for collimating light provided by the laser source, focusing optics for focusing the collimated light provided by the collimating optics, and a detector array disposed at the focal plane of the focusing optics. Two surface acoustic wave transducers are disposed adjacent to one another and adjacent to an optical path between the collimating and focusing optics. The surface acoustic wave transducers are individually connected to antennas which are oriented substantially parallel to one another. The surface acoustic wave transducers launch surface acoustic waves which interact with the laser light and cause the light to be deflected in proportion to the amplitude and frequency of signals applied to the surface acoustic wave transducers by the antennas. The beams deflected by the two surface acoustic waves result in an interference pattern created at the detector array. A microcomputer is provided and coupled to the detector array for comparing the amplitude of the main sidelobes of the interference pattern which is indicative of the direction of arrival of energy received by the two antennas.
