Full name example
OPGW-Ts-А-48-10,9mm 28 kA2∙s-67kN
Cable consist of the aluminum plated 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.
