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.
