Full name example
OPGW-Ts-24-11,2mm-25 kA2∙s-1kN
Cable consist of the central steel loose tube with freely laid fibers. The optical fibers in the loose tube are bundled. Each bundle of fibers has a winding colored synthetic thread. The free space is filled with a hydrophobic gel in the optical loose tube. One lay of reinforcing wires is spirally laid on top.
