We report C-band 100 Gb/s transmission (4 × 28 Gb/s) up to 6.5 km of standard single mode fiber exploiting an InP monolithically integrated WDM transmitter made by an array of four directly modulated DFB lasers on a 100 GHz spaced grid having a 3-dB bandwidth in excess of 20 GHz. To overcome the conventional chirp related chromatic dispersion limitation, we use the compact integrated transmitter in combination with a simplified DSP-free coherent detection scheme suitable for low cost, low power applications.
