Carefully connect optical fiber cables to the XFP’s IN and OUT ports. To
ensure good signal quality, make sure that the optical fibre connector is
fully inserted into the optical connector port.
Note: Do not replace an XFP while the test is running to avoid distorting results.
First stop the test, replace the XFP, and then restart the test.
Note: Only use EXFO supported XFPs. Using non-supported XFPs can affect the
performance and accuracy of the optical port.
