Application

OP3 fiber optical cable is designed for direct burial in soil (including frozen deformated soil), laying on bridges and overpasses. Laying in ducts, conduits, collectors and tunnels is also possible

Cable design

1. Optical fibers (or fiber bundles) of different colors.
2. Central polymer tube filled by waterblocking compound.
3. Galvanized steel wire armoring, including hight-strength wires with tensile load no less than 1670 MPa.

1. Inner PE sheath.
2. Galvanized steel wire armoring, including hight-strength wires with tensile load no less than 1670 MPa.
3. Outer PE sheath.

Armouring free space is filled with waterblocking compound.
