OMNISCANNER
The fiber cables included with your OMNIFiber kit are duplex launch cables
with ST-style connectors. One fiber has white connector boots and the other fiber
has black boots.
8.3 The Reference Methods
OMNIFiber has ST-style connector port adapters. The following diagrams show
how to establish references with duplex launch cables for testing of ST-terminated
networks. For testing of networks terminated with different connector styles, please
call Black Box Technical Support at 724-746-5500.
It is very important that the transmitter (TX port) connections are not
disturbed after the reference value is established
NOTE
When a connector is removed and then reattached, it is unlikely to go
back into the exact same position. As a result, measurements will
change when connections are made or broken.
OMNIFiber measures two fibers of a duplex link in one Autotest operation.
Four reference values will be stored, two from OMNIScanner to OMNIRemote
(TX - RX), the others from OMNIRemote to OMNIScanner (TX - RX).

This method is used when the link includes:
• the loss of one connection at the near end cross connect
• the loss of one connection at the far end cross connect/outlet
• the loss of the cable plant
TIA/EIA-568A, ISO 11801, and IEEE 802.3 (100BASE-X, 1000BASE-X) specify
this method.
