FEATURES  
DESCRIPTION  
INTEGRATED ELECTROABSORPTION MODULATOR  
NEC's NX8567SASeries is an Electro-Absorption (EA) modu-  
lator and wavelength monitor integrated, 1 550 nm Multiple  
QuantumWell(MQW)structuredDistributedFeed-Back(DFB)  
laser diode module. The module is capable of 2.5 Gb/s ap-  
plications of over 240 km, 360 km, 600 km ultralong-reach and  
availableforDenseWavelengthDivisionMultiplexing(DWDM)  
wavelengths based on ITU-T recommendations, enabling a  
wide range of applications  
WAVELENGTH MONITOR FUNCTION  
(Etalon Þlter, Wavelength monitor PD)  
VERY LOW DISPERSION PENALTY  
NX8567SAS Series - over 240 km (4320 ps/nm)  
NX8567SAM Series - over 360 km (6480 ps/nm)  
NX8567SA Series - over 600 km (10800 ps/nm)  
LOW MODULATION VOLTAGE  
AVAILABLE FOR DWDM WAVELENGHT BASED ON  
ITU-T RECOMMENDATION (50 GHz grid, refer to  
ordering information)
