UNDERSEA TELECOMMUNICATIONS CABLE HAVING OPTICAL FIBERS

摘要

The undersea cable has optical fiber embedded in material filling a tube which itself lies inside a helical lay of metal wires having high mechanical strength, the interstices between the wires of the helical lay being filled with a sealing material. The helical lay is surrounded by an extruded sheath made of an electrically insulating and abrasion resistant material, and for the purposes of remotely powering equipment interposed on the cable, the cable includes conductive means either belonging to the helical lay or surrounding it, said conductor means being surrounded by said sheath.
