  • Patent number: 9846280
    Abstract: A two-dimensional (2D) optical fiber array component takes the form of a (relatively inexpensive) fiber guide block that is mated with a precision output element. The guide block and output element are both formed to include a 2D array of through-holes that exhibit a predetermined pitch. The holes formed in the guide block are relatively larger than those in precision output element. A loading tool is used to hold a 1×N array of fibers in a fixed position that exhibits the desired pitch. The loaded tool (holding the pre-aligned 1×N array of fibers) is then inserted through the aligned combination of the guide block and output element, and the fiber array is bonded to the guide block. The tool is then removed, re-loaded, and the process continued until all of the 1×N fiber arrays are in place. By virtue of using a precision tool to load the fibers, the guide block does not have to be formed to exhibit precise through-hole dimensions, allowing for a relatively inexpensive guide block to be used.

    Abstract: An optical cable terminal fixture of the invention capable of increasing a fixing force of an optical cable and also simplifying swage operation, a terminal fixing structure of the optical cable, and an optical module. An optical cable terminal fixture includes a body having an outer sheath fixing part for fixing an outer sheath and a cable insertion path into which optical fibers are inserted, and a wind part having a wind claw on a lateral portion of the body around which a tensile strength wire is wound. Accordingly, by swaging the wind claw on which the tensile strength wire is wound to the outer sheath fixing part, a tensile force applied to an optical cable can be distributed to become resistant to tension.

  • Patent number: 9068875
    Abstract: An optical liquid level transducer is provided that eliminates the need for moving parts, linearization, temperature compensation, material incompatibility with fuel, light output and sensing fluctuations due to temperature changes, and so on. As described, the liquid level is digitally sensed by analyzing axial images of the probe section and outputting changes in liquid level accordingly. The optical liquid level transducer employs an absolute measurement technique with no moving parts such that when power is turned off and restored to the fuel sender, liquid level is automatically determined even if the fuel level in the tank were to change during the “power-off” condition. The optical liquid level transducer is independent of liquid type, temperature and other environmental factors, and does not require special materials that may be incompatible with fuel.

  • Patent number: 9022671
    Abstract: A fiber optic connector fiber stub remover and method for automated fiber stub removal. The device has a top plate with a platen opening, and a platen with a well that carries a polishing film over the well. An air pocket is formed between the polishing film and the well. The platen is positioned with a top surface of the polishing film accessible via the platen opening. A fixture holds connector ends of fiber optic cables with fiber stubs extending therefrom, and a weight biases the fiber stubs into contact with the polishing film. A motor is controlled by a motor control unit to control a ramp up time and final speed of movement of the platen over a timespan. Each connector ends moves independently relative to the polishing film. The air pocket provides shock absorption of the polishing film so that an ideal pressure is exerted on each fiber stub during stub removal.
