TOD Direct Buried Single Tube Dielectric Armor

  1. Outer sheath
  2. Fiberglass Armor
  3. Hydrophobic gel
  4. Loose tube
  5. Hydrophobic gel
  6. Optical fiber


Optical cable is designed for installation in ground including swamps and shallow non-navigable river, in ducts, in pipes, in blocks, in trays, in tunnels, in headers, on bridges and skyways, between and inside buildings, for suspension on the supports of overhead communication lines towers, contact network and railways auto-blocking, power lines, lighting columns, power facilities, as well as with increased requirements for resistance to external electromagnetic influences.

Full name example

Optical cable TOD-P-12Y (1x12) 10kN

The cable consists of a single tube with freely laid fibers. The free space is filled with a hydrophobic gel in the optical single tubes. The single tube is spirally covered with the dielectric rods armor. The free space is filled with a hydrophobic gel between rods. The armor is covered with HDPE sheath.
