DPK cable

dpk

Application

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

Inner free space of optical modules, fillers and armors filled by hydrophobic compound.

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