The Launch/Jumper Cable
The launch/jumper cables are 2 m fiber cables and need to be of good
quality and in excellent condition. Always clean and inspect the launch
cables before use.
Note
The launch cable used to set the
reference value should be the
same type of fiber as the cables
to be tested and certified, 50/
125, 62.5/125 or single-mode.
The fiber cables included with your OMNIFIBER kit are duplex launch
cables. One fiber has white connector boots and the other fiber has
black boots. These colors are consistently used for all graphics through-
out this user guide to avoid confusion.
Fibers can be marked with other color schemes or cable markings to
differentiate them. Pay close attention to the colors to avoid improper
fiber connections.
The Reference Methods
For testing of networks with different connector styles, please consult
the Fluke Networks web site (http://www.flukenetworks.com/support).
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 opera-
tion. Four reference values will be stored, two from OMNISCANNER to
OMNIREMOTE (TX - RX), the others from OMNIREMOTE to OMNISCANNER (TX
- RX).
