Abstract:
1. A method of facilitating provision of a point-to-point cable connection between first and second points separated by an extended span of water including a first region of shallow water and a second region of relatively deep water, the method comprising: providing a plurality of ducts from the first point through the first region of the extended span to an offshore termination point between the first and second points, wherein the plurality of ducts are combined to form a multiple duct conduit, and wherein one of the plurality of ducts is an outer duct that encompasses at least two others of the plurality of ducts, wherein the outer duct includes a water tight seal, wherein a region of trapped air is disposed between the outer duct and the at least two others of the plurality of ducts; installing the plurality of ducts, wherein installing the plurality of ducts includes eliminating the trapped air such that the plurality of ducts sinks in water; placing a first communication cable in one of said plurality of ducts to provide a connection between the first point and said offshore termination point; receiving at said offshore termination point, a second communication cable from the second point; and connecting said first communication cable to said second communication cable at said offshore termination point to create the point-to-point cable connection.
