APPLICATION
Optical pump source for erbium-doped fiber
amplifier(EDAF)
ABSOLUTE MAXIMUM RATINGS (Tld=25°C)
Parameter Symbol Conditions Rating Unit
Laser diode Forword current If CW 800 mA
Reverse voltage Vrl - 2 V
Photodiode Reverse voltage Vrd - 20 V
for monitoring Forward current Ifd - 2 mA
Cooler Voltage Vpem - 4.5 V
(Note) Current Ipem - 1.8 A

Storage temperature Tstg - -40~+70
Note. Evan if the thermo-electric cooler (TEC) is operated within the rated conditions, uncontrolled current
loading or operation without heatsink may easily damage the module by exceeding the storage. Ther mistor
resistance should be properly monitored by the feedback circuit during TEC operation to avoid the
catastrophic damage.
