In-Line Optical Quality Measurements for Gigabit Multimode Optical Networks

Luna Innovations proposes a multi-measurment system, allowing for 24 hour in-line network quality characterization. The system builds on Luna"s Optical Backscatter Reflectometer (OBR), which delivers unprecedented inspection and diagnostics capabilities for the fiber optics industry. The goal of the proposed development effort is to both broaden the capabilities of the OBR, and to make the current system more reliable for multimode fiber inspection. The proposed solution combines optical frequency domain reflectometry (OFDR) and superheterodyne detection to provide measurements of defect location, optical loss, power, and laser quality in a single, in-line, inspection system. The solution provides 24 hour monitoring of system health, while limiting the cost, complexity, and time required to make multiple system quality measurements. In Phase I, Luna will investigate the feasibility of superheterodyne detection using modified OFDR-capable hardware. Luna will also research and develop a reliable mode conditioner, allowing for repeatable and compliant loss measurements in multimode fiber. Finally, Luna with work with NAVSEA to determine an aggressive commercialization strategy and the fastest route to fleet integration.
