2 m Launch Cable
Coupler
Two Jumper Reference Method in Loopback Mode
The OMNIFIBER Main can be used without the remote to make measure-
ments on a single fiber. In this state the TX fiber is looped back to the
RX port of the same OMNIFIBER adapter.
Note
During the Autotest, the loss and length of the white fiber will be
subtracted from the length of the fiber under test. Since the loss in a
short jumper cable is negligible, the loss measurement of the fiber
under test will be accurate. The length measurement will be off by
the length of the jumper cable (about 2 meters). This primarily
affects the length accuracy of very short cables.
1. Connect the launch
cable to the OMNIFIBER.
The black fiber
attached to the TX
(transmit) port and the
white fiber to the RX
(receive) port.
2. Use a connector
adapter to mate the
connections on the
other end.
3. Press (Setup) to open the SETUP screen and then select Set
Reference to set the reference.
4. Disconnect the white connector from both the RX port and the
connector adapter. Do not disturb the black fiber attached to
OMNIFiber’s TX port.
5. Leave the two white ends dangling.
6. Attach the cable to be tested to the connector adapter and the
OMNIFiber’s open RX port .
