PRELIMINARY DATA SHEET  
NEC's 1480 nm InGaAsP MQW FP  
PUMP LASER DIODE MODULE  
NX7461LE-CC  
FOR EDFA APPLICATION (150 mW MIN)  
FEATURES  
• InGaAsP MQW-FP LASER DIODE  
• HIGH OUTPUT POWER:  
Pf = 150 mW MIN @ IF = 600 mA CW  
• INTERNAL OPTICAL ISOLATOR, THERMOELECTRIC  
COOLER AND InGaAs MONITOR PHOTO DIODE  
• SINGLE MODE FIBER PIGTAIL  
• HERMETICALLY SEALED 14-PIN BUTTERFLY PACKAGE  
DESCRIPTION  
NEC’s NX7461LE-CC is a 1480 nm pumping laser diode  
module with optical isolator for an EDFA (Er Doped optical  
Fiber Amplifier) that can expand the transmission span  
and compensate optical losses. This device is a Multiple  
Quantum Well (MQW) structured Fabry-Perot (FP) laser  
diode that features high output power, high efficiency, and  
stable fundamental mode.
