We report the performance of a chirped laser in IMDD-based transmissions and we show that the interplay between laser chirp and fiber dispersion can be very attractive for long distance PONs if adaptive OFDM modulation is used.
We experimentally demonstrate AMOOFDM transmissions at 11.5Gb/s over 513km uncompensated standard single mode fiber (SSMF) and 30Gb/s over 650km dispersion managed fiber (DMF) through intensity modulation and direct detection.
Experimental demonstration of a bit rate as high as 32 Gbit/s is achieved over 20 km SMF for NGPON in a temperature range of 5??C-60??C using AMOOFDM direct modulation of a linear laser.
A bit rate as high as 19Gbit/s transmission was experimentally demonstrated for NG-PON without chromatic dispersion compensation by direct modulation of DFB laser using DMT signal combined with adaptive power-bit loading algorithm.
