2.1 Features
The EM316EDFA board can run in standalone mode without any input from a management
module. The EM316EDFA analog input power determines the output power because the module
runs at a fixed gain.
EM316EDFA status is reported through SNMP through a network management module as well as
by LEDs on the front panel.
The green “SD” LED on the front panel indicates input greater than the thresholds corresponding to
the EDFA module type, as indicated in the table below.
EM316EDFA-BR -8 dBm
EM316EDFA-LPR -30 dBm
A green LED at front panel (Optical Output) indicates output power greater than -10 dBm.
The module temperature is measured from 0
o C to 70 o C and reported to management. To protect
against excessive heat, the laser shuts down when measured temperature reaches 70 o C.
