* See attached specification sheet for recommended maximum temperature exposure times.

  • Number, type and temperature rating of fiber optic elements is dependent on customer request.
  • While insulation is rated to 1-hour exposure of 500°F, the fiber optic element in the cable will dictate the maximum operating temperature for the cable.
  • Fiber in metal tube (FIMT): stainless steel OD of 0.046 in. (1.17 mm). Extra fiber length (EFL) is specified by customer request and subject to manufacturing capabilities.
  • Attenuation increase in the fiber optic under loaded conditions may vary.
  • The armor wires are high tensile, Galvanized Extra Improved Plow Steel (GEIPS), and coated with an anticorrosion compound for protection during shipping and storing. Wires are preformed.
  • Conductor resistance is measured at 68 °F. Voids in the copper strand are filled with a water-blocking agent to reduce water and gas migration.
  • All values shown are nominal or typical values.
