The invention is directed toward an optical pressure sealing coupling providing pressure sealing feed through a fiber optic probe used as a monitoring device. The invention is primarily adapted for feeding optical signals from one section of a probe under high pressure cryogenic conditions to another section of the probe at ambient pressure. The novelty of the invention is in the combination of optically coupling and sealing the probe against the high pressure differential while maintaining discrete optical send/receive channels through the connection despite vibration. The advantages appear to be a rugged coupling having sensitive optics contained internally and eliminates the requirement of independently sealing the probe itself.
