Optical power
Option 10 runs the AIB test unit and allows you to measure
the optical output of the adapter. This test requires that
the fiber be removed and an optical power meter be
attached. See “ESCON Optical Power Measurement Test”
on page 5-57 for additional information.
Light reception
Option 11 runs the AIB test unit and also tests whether the
attached fiber is transmitting light. This test can be used to
determine if the remote end of the fiber is connected. For
an example of using this function, see “Testing the
Adapters” on page 5-49.
