NEC's 1550 nm  
InGaAsP MQW DFB  
LASER DIODE IN COAXIAL PACKAGE  
for 622 Mb/s APPLICATION  
NX8504BE-CC  
NX8504CE-CC  
FEATURES  
DESCRIPTION  
• PEAK EMISSION WAVELENGTH:  
λP = 1550 nm  
NEC's NX8504BE-CC and NX8504CE-CC are 1550 nm Dis-  
tributed Feed-Back (DFB) laser diode coaxial modules with  
optical isolator.  
• OPTICAL OUTPUT POWER:  
Pf = 2.0 mW  
These modules are ideal as a light source for Synchronous  
DigitalHierarchy(SDH)system, STM-4, long-haulL-4.2, L-4.3  
ITU-T recommendations.  
• INTERNAL OPTICAL ISOLATOR  
• InGaAs MONITOR PIN-PD  
• WIDE OPERATING TEMPERATURE RANGE:  
TC = -10 to +85°C  
• WITH SC-UPC CONNECTOR  
• BASED ON TELCORDIA RELIABILITY  
ELECTRO-OPTICAL CHARACTERISTICS (TC = -10 to +85°C, unless otherwise specified)
