Application

DOL optical fiber cable is designed for laying in ducts, conduits, collectors, tunnels, on bridges and overpasses, buildings,in case of danger of damage by rodents. Direct burial in soil is allowed in case of increased requirements for protection against water penetration.

Cable design

1. Central strength member – GRP rod.
2. Optical fibers of different colors.
3. Plastic tube filled with hydrophobic compound.
4. Filler.
5. Waterblocking tape.
6. Corrugated steel tape with polymer coating.
7. Outer PE sheath.
