DOTs cable

dots

Application

DOTs optical fiber cable is designed for suspension on overhead lines, on electrical transmission line towers, on electrical contact networks of railways. Also suitable for cabining in sewers, special pipes, in case of increased requirements for resistance to external electromagnetic influences, through ducts, conduits, collectors, tunnels and in buildings.

Cable design

  1. Central strength member – GRP rod.
  2. Optical fibers of different colors.
  3. Polymer tube filled with hydrophobic compound.
  4. Filler.
  5. Glass yarns.
  6. Outer PE sheath.

Inner free space of optical modules, fillers and armors filled by hydrophobic compound.

Specifications

  • Fiber count – up to 576;
  • Static tensile strength – from 3 kN to 15 kN;*
  • Crush resistance – from 0,2 kN/cm to 0,4 kN/cm;*
  • Impact resistance – 20 J;
  • Cable length on a drum – up to 4 km.

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).

In case of special demands for protection from electrocorrosion, outer sheath may be produced of tracking-resistant material.
