Ruggedized Multifunction Fiber-Optic Transceiver Optical Subassembly Navy STTR FY2005 Sol No.: Navy STTR FY2005 Topic No.: N05-T005 Topic Title: Ruggedized Multifunction Fiber-Optic Transceiver Optical Subassembly Proposal No.: N054-005-0338 Firm: Ultra Communications Inc 310 Via Vera Cruz, Suite 105 San Marcos, California 92078 Contact: Charles Kuznia Phone: (760) 420-3486 Abstract: This proposal describes a Phase I effort in an overall program to implement optical time domain reflectometry (OTDR) within multi-Gbps multimode fiber optic transceivers. The end goal is to develop transceivers capable of detecting and isolating fiber faults along the cable plant in a military environment. This Phase I effort will investigate a solution that integrates the OTDR functionality into the transceiver IC so that the overall optical subassembly and module physical envelope are not impacted. This solution requires a mechanism for detecting back-reflected light from the fiber. We will work with our STTR institutional partner, Sandia National Labs, to investigate devices for this detection mechanism. We anticipate a 7 month performance period for the technical portion of this investigation. There will be a mid-term "User's Workshop" to present this concept and gain feedback from major avionic military system integrators. Benefits: This technology will lower the cost of owernship and maintenance of parallel fiber optic communcations systems. Return
