43-Gbit/s operation of 1.55-/spl mu/m electro-absorption modulator integrated DFB laser modules for 2-km transmission

We successfully demonstrated 43-Gbit/s operation of 1.55-μm electro-absorption modulator integrated DFB laser module for 2-km transmission for the first time. A clearly opened eye, 0.6 dB power penalty, and +2.1 dBm output power were obtained respectively. (2 pages)
