changes the LED and display as described in table 4-1 in Section 4
Troubleshooting.
During normal operation, the EDFA displays “1550 EDFA.” When the “select”
button is pressed, the display changes to show system information according to the
menu structure of Fig. 3-1. By repeatedly pressing “select,” the display cycles
through the menu headings “Optical,” “Pump 1,” “Pump 2,” on up to “Pump 4 if
installed,” and “System.”
In EDFA’s where fewer pumps are installed, the menu headings for those lasers
not installed are eliminated. The down button moves the display down in the menu
structure; if the bottom of the menu is reached, the display wraps back to the top.
For instance, if “Pump 1” is shown and the down button is pressed, then the
display shows the pump 1 laser bias current. The up button moves the display up
the menu structure.
