Loopback Autotest using OMNI

Fiber

Main

This configuration is used to test single fibers, reels and short cables when

both ends of the fiber under test are accessible from the same location.

Note: The loopback Autotest assumes that the 2-Jumper Method was used

to make the reference measurement.

To run a Loopback Autotest proceed as follows:

1. Do not disconnect the

black launch cable, which is

attached to the TX port of the

OMNI

Fiber

(it is circled in the

graphic).

2. Do not disconnect the

coupler from the black

launch cable (it is circled in

the graphic).

3. Disconnect the white launch cable from the RX port of the OMNI

Fiber

and the connector sleeve. Leave the two white connectors dangling.

4. Attach the cable to be tested to the RX port on the OMNI

Fiber

and the

connector sleeve.
