<p>A sealing assembly for an optical fibre feed through inhibits passage of water or gases via a fibre"s protective sheath while preserving mechanical protection of the fibre. A length (A-A") of the fibre (4) is exposed by removal of the corresponding sheath portion. Both the exposed surface of the fibre (4) and the ends (6", 6) of the sheath (5) are sealed into a common bore (2) in a ferrule (1). Demountable end members (9, 10) may be provided, to extend the bore (2) into which the sheath ends (6", 6) are sealed. The sealing assembly finds particular application in optical fibre feed through at submarine cable repeater housing bulkheads. </p> |
