7 Using the Light Source
You can use the OX1 as a light source to perform measurements with a
power meter. By default, the modulation is set to CW (continuous), but you
can select another value, depending on the type of tests you want to
perform.
³ For loss measurement, you should choose a continuous pattern.
³ For fiber identification, you should choose any modulation value other
than continuous. This will allow the person at the other end of the link
to identify the fiber under test, which is particularly useful when
working with cables containing many fibers.
When the light source is on (off by default), it emits light constantly until
you turn it off, but you can set a timer allowing light emission only for a
certain period of time (up to 999 minutes). The first time you work with the
source, the timer is disabled. The default value is set to 30 minutes when it
is enabled. As soon as the timer reaches zero, the light emission stops
automatically. If you enable this feature and decide not to edit the number
of minutes during which you want the source to emit light, it will stop after
30 minutes. The application displays clearly the countdown on screen. The
state of the timer (on or off) and the value you have entered are kept in
memory when you close the page.
Note: At any time, you can switch from local measurements (that are not part of
a TestFlow job) to measurements within a TestFlow job. All the
measurements are kept in memory. You can also open, in turn, the power
checker and the source page.
IMPORTANT
³ When you exit the source page, the light source continues to
emit light. The light emission stops automatically when you
open the power checker or the Fiber Xplorer page.
³ If you have not set a timer to automatically turn off the source,
do not forget to turn it off when the test is complete.
Otherwise, the source will emit constantly and could drain the
battery of the unit.
