CHAPTER 8: OMNIFiber Reference

NOTE

This method is called “Method B” in TIA-526-14A and

“Method A.1” in

TIA-526-7.

1. Connect one end of a black launch cable to the TX (transmit) port of the

fiber adapter that is attached to OMNIScanner.

2. Connect the other end of that black launch cable to the RX (receive) port of

the fiber adapter that is attached to OMNIRemote.

3. Leave the two white fiber connectors dangling and unconnected.

4. Connect one end of another black launch cable to the TX (transmit) port of

the fiber adapter that is attached to the OMNIRemote.

5. Connect the other end of that black launch cable to the RX (receive) port of

the fiber adapter that is attached to the OMNIScanner.

6. Leave the two white fiber connectors dangling and unconnected.

7. Set the Reference.

8. ;Disconnect only the following two ends: OMNIFiber main RX (receive) and

OMNIFiber remote RX (receive). OMNIFiber main TX and OMNIFiber

remote TX stay connected.

9. Connect the white fibers to the appropriate RX ports.
