Application
DPO optical fiber cable is designed for cabining in special protective plastic pipes, inside buildings and tunnels, as well as for suspension on overhead lines with attachment to an external carrying elements (to cables, wires, etc.). Laying in the ducts, conduits, underground tunnels is also allowed.
Cable design
- Central strength member – GRP rod.
- Optical fibers of different colors.
- Polymer tube filled with hydrophobic compound.
- Filler (if needed).
- Outer PE sheath.
Inner space is filled with hydrophobic compound or/and waterblocking materials.
DPO cable has 6 or more stranding elements.
