Application
DPC fiber optic cable is designed for direct burial in soil, laying in ducts, conduits, collectors, tunnels, bridges and overpasses, buildings. It is also allowed to lay cable in the ground, exposed to low temperature deformations, if cable resistance to tensile forces is at least 20 kN.
Cable design
- Central strength member – GRP rod.
- Optical fibers of different colors.
- Filler.
- PBT tube filled by waterblocking compound.
- Inner PE sheath.
- Galvanized steel wire armoring, including hight-strength wires with tensile load no less than 1670 MPa.
- Outer PE sheath.
Armouring free space is filled with waterblocking compound.
