Do not look directly into the fiber receptacle. Use a viewing card to help determine whether the fiber
amplifier is generating an output.
The following table describes some typical problems that may be encountered while using the EDFA100S or
EDFA100P and possible solutions to these problems.
Problem Solution

Unit is enabled but there is no output.
1. Check to make sure you are using the correct type of fiber
patch cable for the particular wavelength.
2. Disconnect the fiber patch cable and use a viewing card to
check to see if there is light being output from the FC/APC
