DAC cable

das

Application

DAC fiber optic cable is designed for direct burial in soil (including frozen deformated soil), through rivers crossings, navigable rivers and deep-water lakes and reservoirs, bayous, ducts, conduits, collectors, tunnels, bridges and overpasses, buildings.

Cable design

  1. Central strength member – GRP rod.
  2. Optical fibers of different colors.
  3. Filler.
  4. PBT tube filled by hydrophobic compound.
  5. Waterblocking aluminum tape with polymer coating.
  6. Inner PE sheath.
  7. Galvanized steel wire armoring, including hight-strength wires with tensile load no less than 1670 MPa.
  8. Outer PE sheath

Armouring  free space is filled with waterblocking compound.
