  • fiber optic cable locating

    what frequency or method to locate fiber optic cables ? do you locate trace wire with fibre optic cable ?

    Re: fiber optic cable locating

    Some fiber optic cable can be located and some can not. If the cable has a metallic sheath, then it can carry a signal and therefore be located. If there is no metal within the fiber optic cable then there is no way to apply a signal to it. In theory, these un-locatable fiber optic cables should have a tracer wire buried with it, but in reality most do not.

    Locating a cable with a metal sheath is just like locating a power or telephone line. The induction clamp is useful if you don’t want to disconnect the line. Dropping the box in induction mode is also useful if you don’t have access to the pedestal.

      if fiber optic cable has no access to attach clamp to induce signal the cable does not give off signal frequency is this correct and does trace wire give of signal by itsself or does signal have to be induced to trace wire also with clamp ?

        It is possible that some signal has bled onto the line from power lines, radio signals, or other sources. If this is the case you will be able to locate the line with a passive search. When doing a passive search, one only uses the receiver and not a transmitter. If you have a RIDGID SeekTech locator, set it on the Omni-Seek mode (looks like an infinity symbol on the menu) and sweep the area. This will search all passive bands at one time and if there is any signal on the line you will find it in Omni-Seek mode.

        If you are not able to locate the line using a passive search then you will need to place a signal onto the line with a transmitter. If you don’t have access to direct connect to the line or use the clamp, you will need to use induction mode. For more information on how to use induction mode please see the training section on the RIDGID website.
