Running a Fiber Autotest
Some Autotests do not have a fixed loss limit. The Optical Link Budget
(OLB) is calculated based on the wavelength, the length of the cable,
and the number of connectors and splices.
OMNISCANNER will automatically display the CONNECTIONS screen if
you are running an equation based Autotest (TIA 568B, ISO 11801, or
1000 Base F).
1. With the Connections: field highlighted,
press ENTER. Use the é or ê arrow key to
adjust the number of connections in your link.
To determine the total number of connections,
simply count all of the connections (connector
pairs) on one fiber. OMNISCANNER will assume
that both fibers of a duplex link have the same
number of connections.
2. To change the number of Splices, use the ê to highlight the field
and press ENTER. Use the é or ê arrow key to adjust the number of
splices in your link. To determine the total number of splices, simply
count all of the splices on one fiber. OMNISCANNER will assume that both
fibers of a duplex link have the same amount of splices.
3. After editing the fields, press to run the Autotest.
OMNISCANNER starts the Autotest after the number of connections and
splices has been entered.
Note
If you are running a Two Way test, you will be
prompted to swap the fibers. (See Chapter 4 -
Setup: Fiber Test Options for further informa-
tion.)
4. Swap the Launch Cable’s connectors as
indicated in the graphic. Do not disconnect the
Launch Cables from the OMNIFIBER!
