A series of 1550-nm DFB laser diodes are designed for long-haul DWDM and metro network systems. The NDL7910 and NDL7911 modules provide reach of up to 360 km, and the NDL7912 provides ultralong reach of up to 600 km. The modules have on-board electroabsorption modulators, designed to replace a CW source/LiNO3 modulator combination. They have a data rate of OC-48, 4-GHz typical spectral linewidth, low modulation noise, and are wavelength-selectable for ITU-T standard.
