Abstract
A pressure compensated, fiber optic coupler for use underwater includes a water impermeable housing have first and second apertures to receive the respective optical fibers. One fiber is permanently held by the seal to the first aperture. The other fiber is inserted through the second aperture which is sealed by a conformable seal which is biased closed when no fiber is inserted through it. An incompressible, refraction of index matched fluid fills the interior of the housing to provide pressure compensation. The conformable seal is conveniently constructed of flexible neoprene and the housing is preferably titanium.
