Abstract: Recently, coherent optical OFDM (CO-OFDM) has been proposed for optical networks to combat chromatic dispersion. CO-OFDM system has been successfully processed and recovered for transmitted signals without optical chromatic dispersion compensation. However, in optical links, the available optical power is limited due to fiber nonlinearity, and power consumption. As previously reported, we focused on the minimizing the optical power and have proposed CO-OFDM with punctured LDPC codes and variable amplitude block codes to overcome the above-mentioned problems. In this paper, we focus on the implementation of the proposed CO-OFDM and evaluate the influence of laser linewidth and modulation level for coherent optical OFDM with punctured LDPC codes.
