UNIT 2
Fiber Length Measurement
1 - On one end of the fiber cable, loop back two of the
fibers with one of the patch cords.
2 - On the other end of the fiber cable, connect one patch
cord to each of the fibers being used for the test.
Connect the other end of the patch cords to the
receiver and transmitter ports on the VOLT. It does not
matter which patch cord connects to which fiber.
3 - Power on the VOLT into length test mode by flipping
the switch to TEST. In a few seconds, the display will
show the length of the fiber in kilometers. In the
example at right, the link is 1.250 kilometers.
NOTE: If the green indicator LED does not light up, this
means that the battery has insufficient power for a valid
test, and must be replaced before continuing.
Visual Fiber Identification
1 - Connect the VOLT to the fiber you are testing via a
patch cord as shown at right.
2 - Power ON the VOLT into fiber identification mode by
flipping the switch to TEST. This mode emits a flashing
beam of high-intensity red light into the fiber.
3 - Identify the fiber by looking for the flashing red light
emitting from the connector.
