Abstract

This paper describes two methods for characterizing underwater optical elements under both hyper-baric pressure and high optical power. Commercial optical feedthroughs to be tested were inserted in a hyper-baric vessel and a 600 bar pressure was applied as an optical power of several Watts was sent over the optical fibers. An unexpected decrease of the optical losses was evidenced.
