Multichannel Fiber Optic Package Interface for Avionics Navy SBIR FY2009.1 Sol No.: Navy SBIR FY2009.1 Topic No.: N091-039 Topic Title: Multichannel Fiber Optic Package Interface for Avionics Proposal No.: N091-039-0236 Firm: Applied Optical Systems, Inc. 1700 Capital Avenue, Suite 50 Plano, Texas 75074-8039 Contact: Richard Laughlin Phone: (903) 561-6011 Web Site: http://www.appliedopticalsystems.com/ Abstract: Applied Optical Systems (AOS) has a design concept for a family of "DENSE-HIGH TEMP FIBER INTERFACE" fiber feed-throughs, compatible with the Small Form Factor SFF Opto-Electronic packages. The feed-throughs are both un-connectorized and connectorized. These feed-through will provide a 250 micron pitch while attaining a > 10^-9 Hermitic seal and withstand temperatures greater than 225C. In addition they will withstand the rigorous shock and vibration encountered in the Avionics environment. This family includes 3 specific feed-throughs: 1.) A 12 Fiber Single-Mode (SM) or Multi-Mode (MM) feed through is offered with < 0.5 dB insertion & -55 dB back reflection. 2.) Connectorized 12-fiber SM feed through < 0.5 dB insertion loss and -55 dB back reflection. Dim, 10 mm dia. x 4 mm thick or linear array, 1.5 mm pitch, 16 mm x 6 mm x 4 mm package. The linear package may be attached at the front on combined with the electrical connections at the back of the SFF package for a pluggable module that includes the fiber connections. 3.) Connectorized 12-fiber MM fiber feed through insertion loss < 0.5 dB; a back reflection < -20 dB. package dim. 5 mm dia. x 3 mm. Benefits: The application of fiber optic sensing through interferometer technology has enabled the petroleum industry to control and monitor well completion and reservoir management with accuracy. Single mode fiber optic utilizing Bragg grating technology at various intervals along the drill column takes advantage of the change in index of refraction between the core/clad wave guide. The reflection of a laser provides accurate measurements of temperature, pressure, and life aging characteristic along the entire column of fiber optic link. The availability of fiber optic connectors that can sustain operation at 300 C has long been the "missing link" to successful and cost effective deployment of this technology. Development of successful high temperature fiber connectors as a dual use technology could become a market enabler, for existing well/reservoir completion technology, but also an enabler for oil shale recovery. AOS estimates that the market for cost effective high temperature fiber optic connectors/systems for the energy industry along could exceed $13M with the next five (5) years, pending successfully commercialization of a high temperature fiber connector.
