摘要

An optical fibre gland for a submerged repeater comprising an insulating body (1) having a bore (4) accommodating a pressure tube (5). A high pressure end fitting (8) is secured to the tube and the body and a low pressure end fitting (12) is secured only to the tube. The tube and fibres are water and gas blocked and the construction is such as to enable the gland to operate satisfactorily over a wide temperature range.
