Note
1. GND is the symbol for signal and supply (power) common for the module. All are common within the module
and all module voltages are referenced to this potential unless otherwise noted. Connect these directly to the
host board signal-common ground plane.
2. An alarm condition is present when Pin 4 changes from the normal condition of LVTTL high to a condition
LVTTL low. The alarm condition can be for Output Power, Pump Laser Bias, Case Temperature and/or Power
Supply Voltage. Read specific alarm condition through I2C interface.
3. Pulled up in the module to a voltage between 3.15 V and 3.45 V.
4. Voltages applied to this pin do not impact operation or performance of the module.
5. Connected in series with a capacitor (0.1uF) and resistor (51Ω) to GND in the module.

Digital Diagnostic Monitoring (DDM) Functions
As defined by the SFF-8636, Edgecore’s Packet-Optical EDFA modules provide digital diagnostic monitoring
(DDM) functions and alarm/warning flags via a 2-wire serial interface, which allows real-time access to the
operating parameters including temperature, supply voltage, pump bias current, optical input power, optical
output power, and gain report.
