Application
OPC optical fiber cable is designed for direct burial in soil, in the ducts, conduits, collectors, tunnels, bridges and overpasses, buildings. It is allowed tolay cable in the ground, exposed to low temperature deformations, if cable resistance to tensile forces is at least 20 kN.
Cable design
- Optical fibers (or fiber bundles) of different colors.
- Central polymer tube filled by waterblocking compound.
- Galvanized steel wire armoring, including high-strength wires with tensile load no less than 1670 MPa.
- Outer PE sheath.
Armouring free space is filled with waterblocking compound.
Specifications
- Fiber count – up to 64;
- Static tensile strength – from 4,0 kN to 50,0 kN;*
- Crush resistance – from 0,4 kN/cm to 1,5 kN/cm;*
- Impact resistance – 30 J;
- Allowed bending radius – from 140 mm to 280 mm;
- Cable diameter – from 7,0 mm to 14,0 mm;
- Cable weight – from 90 kg/km to 450 kg/km;
- Outer PE sheath insulation resistance (circuit “armor – land (water)”) – 4000 MOm*km;
- Cable length on a drum – up to 25 km.
Diameter, weight and bending radius are reference values.
At the demand of the customer, for cables used in buildings, ducts, conduits and tunnels, outer sheath may be made of flame retardant polymer composition not containing halogen (LSZH).
