Overview

Our unique Cold Clamp locates fiber optic cable breaks & faults to a physical accuracy of better than 1 meter over long distance.

It causes a temporary optical loss marker at a location near the fault, allowing any mini-OTDR user to find the physical fault with great accuracy.

In practice a fiber OTDR distance measurement is accurate to 0.5% - 2%. Real-world systems also often have cable coils & undeclared topologies that impact distance measurement. So a cable fault can be hundreds of meters away from an expected location, even when using best OTDR fault finding practices.

  • Works brilliantly over long distances on underground faults
  • Reduces network hazard and days of labor as exploratory trenching is eliminated
  • Minimizes community disruption and excavation damage
  • Find a hidden fault or break in fibre cables where there is no visible evidence
  • Minimizes service disruption, since it can be used on a live system
  • Economical repair allows revival of dark or abandoned fiber lines, reclaiming capacity
  • Inexpensive, non-destructive & field proven locator. Telcordia (Bellcore) report available
  • Use your existing training & OTDRs
  • Safety kit & work practices are provided. (a small amount of liquid nitrogen is easier to acquire and manage safely than most people think!)
