Abstract A high temperature optical link capable of multi-megabits per second data rates at 300°C is presented. The system utilizes wide bandgap optical sources and detectors to achieve extreme temperature operation. Testing was conducted at multiple temperatures between room temperature and 325°C and at multiple light source currents. Light coupling into and out of a UV capable optical fiber was evaluated, and a model was created utilizing the test data of the photodiode dark current and the fiber optic cable insertion loss and attenuation and assess optical communications capability to 325°C and beyond.

Temperature Ranges

Present fiber optic connections need to align two or more optical fibers to accuracies of microns (multimode fiber) and tenths of a micron (single more fiber). For connections in rugged applications, consisting of wide temperature ranges, substantial vibration, or in the presence of contaminants, the alignment of normal physical contact connections becomes even more difficult. New expanded beam connectors make fiber optic connections more durable, and help stabilize the transmission of high speed optical signals between systems, boxes, boards, and devices in these harsh environments.
