OPK cable

opk

Application

OPK optical fiber cable is designed for suspension between buildings,on supports (towers) of communication lines, for cabining through tunnels, underground, inside buildings, as temporarycable inserts.

Cable design

  1. Optical fibers of different colors.
  2. Polymer tube filled with hydrophobic compound.
  3. Attached straight member – rope, made from galvanized steel wires with tensile strength no less than 1670 MPa.
  4. Outer PE sheath.

Cable size and weight parameters in dependence of fiber count and tensile load are listed in the table.
