    Abstract: An apparatus configured to function as a pluggable single-wavelength bidirectional transceiver in a switching network. The apparatus includes: a 2×1 fusion coupler; an input/output optical fiber, a detector optical subassembly (OSA) fiber and a laser OSA fiber all connected to the 2×1 fusion coupler; and a transceiver that includes a transceiver electronic circuit printed wiring board (PWB) and laser and detector OSAs electrically coupled to the transceiver electronic circuit PWB. The laser OSA includes a laser that is situated to transmit light to the laser OSA fiber, while the detector OSA includes a photodetector that is situated to receive light from the detector OSA fiber. The transceiver electronic circuit PWB also includes a multiplicity of transceiver input/output metal contacts arranged at one pluggable end of the PWB.

    Abstract: An airplane fuel level optical sensor using one side-emitting plastic optical fiber (SPOF) and two fluorescent plastic optical fibers (FPOFs) to detect the airplane fuel level without using any electrically conductive component or element placed inside the fuel tank. This dual-FPOF sensor is capable of achieving high resolution and high accuracy with a one-time calibration in the actual airplane's fuel tank environment. One embodiment of the dual-FPOF sensor uses one SPOF and two FPOFs to detect fuel level change based on the optical signal output from the two FPOFs. The sensor design uses large-diameter (core and cladding), lightweight, low-cost and high-durability plastic optical fiber, which is very desirable for airplane installation.

    Abstract: Systems and methods that use an optical impedance sensor that eliminates electricity for measuring fuel quantity in fuel tanks. The optical impedance sensor comprises two optical fibers spaced apart inside a meniscus tube, one to transmit light along its length and the other to receive light along its length. The meniscus tube minimizes the sloshing of fuel level. The fuel level in the tank modulates the optical impedance between the two optical fibers, resulting in changes in the total light received by an optical detector. Depending on fuel tank height, the optical impedance sensor may comprise different embodiments in which the detection apparatus shapes the light to be unidirectional (emitted and collected only on one side of the fiber) or omnidirectional (all directions).

    Abstract: An epoxy-free, high-durability and low-cost plastic optical fiber splice design and fabrication process which meets commercial airplane environmental requirements. The splice design: (1) does not require the use of epoxy to join the end faces of two plastic optical fibers together; (2) incorporates double-crimp rings to provide highly durable pull force for the plastic optical fibers that are joined together; (3) resolves any vibration problem at the plastic optical fiber end faces using a miniature stop inside a splice alignment sleeve; and (4) incorporates a splice alignment sleeve that can be mass produced using precision molding or three-dimensional printing processes.
