1.Connect the first launch cable to the fiber adapter that is attached to OMNIScanner. The black fiber attaches to the TX (transmitter) port and the white fiber to the RX (receiver) port.
2.Connect the second launch cable to the fiber adapter that is attached to OMNIRemote. The black fiber attaches to the TX (transmitter) port and the white fiber to the RX (receiver) port.
3.Use two connector adapters to mate the black TX connector to the white RX connector through a third jumper cable.
4.Use two connector adapters to mate the other black TX connector to the white RX connector through a third jumper cable.
5.Set the Reference.
6.Remove the third jumper cable, located in the center, and the connector adapters without disturbing the OMNIFiber connections.
8.3.4METHOD A: TWO JUMPER REFERENCE METHOD IN LOOPBACK MODE
The OMNIFiber main can be used without the remote to make measurements 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 attaches 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.
