Abstract

A junction box for joining a plurality of cable elements of an underwater cable is provided. The junction box comprises a sleeve having a major axis, the sleeve defining an internal region for accommodating joins between the cable elements. First and second sleeve retainers each comprise a bore for receiving a part of the cable which extends into the internal region. The first and second sleeve retainers are each detachably attached to a respective opposing end of the sleeve by an outer set of fasteners extending into the sleeve. A first sealing member provided at the interface between each said sleeve retainer and the sleeve. The first sealing member is configured to prevent ingress of hydrogen into the internal region from along the interface.

Abstract

A connection member (1) for coupling first and second cable devices mounted to an optical communications cable. The connection member comprises two semi-cylindrical parts (2, 3) being adapted to be coupled together around the communications cable (23, 24), and fibers associated with the cables and further adapted to be coupled to and between the first and second devices. The first and second devices comprise a universal joint (21, 22), a repeater (20), a combined joint-repeater, a filter, a coupler, a branch, a bend limiter(25, 26, 27, 28, 29, 30) or an optoelectronic device.
