3. Operation
1. Determine the head end of cable to be identified, and pick out the one (or two, depending
on the testing mode adopted) from the target optical cables to connect the testing equipment;
2. Connect the optical fiber to open testing equipment at the head end of the target cable. It
shall be noted that the optical interface is of FC/APC for the testing equipment, and please
use the transfer jumper for connection if the optical connector is not of FC/APC for the
target cable termination. Our standard configuration includes the jumper from FC/APC to
FC/UPC;
3. The optical fiber connector shall be of PC at the end of target cable in order to enhance
the strength of reflection signal, and reflector may be connected at the end if necessary;
4. The light power value received shall be greater than -55dBm at the testing equipment,
otherwise please check whether the connection is correct or whether the line loss is too
large;
5. Unfasten at least 1m of the original binding fiber bundle at the identified cable, and
number each cable with tape;
6. Use the headset of the testing equipment at the head end of target cable to listen to the
voice by tapping the cable, and adjust the sound volume to the appropriate value through the
adjusting knob on the headset;
7. Use the metal rod of screwdriver to tap each cable with the same strength at the cable to
be identified, and use the headset of the testing equipment at the head end of target cable to
listen to and record the voices of tapping different cables. It shall be noted at this step that:
in order to prevent the vibration from transmitting to other cables when tapping one, a
sponge or soft cloth shall be used at the binding to separate the cable tapped with other
cables. The same effect may be achieved if one person holds the cable with his hands and
another taps the cable;
8. The above step shall be repeated by reducing the tapping strength if the voices by tapping
different cables are almost the same. In most cases, the cable shall only be tapped slightly
with finger;
9. Analyze which one is the target cable. There shall be an optical cable of which the voice
