The Impact of Transmitter Chirp Parameter on the Power Penalty and Design of 50 Gbit/s TDM-PON

We study the impact of transmitter chirp parameter (effective α-factor) on the chromatic-dispersion-induced power penalty in 50-Gbit/s TDM-PON. We experimentally show interplay of chirp and dispersion using 50G-class integrated EML-SOA driven in distinct operating points.
