Dispersion tolerant 200 Gb/s dual-wavelength IM/DD transmission with 33dB link budget for next generation PON

We demonstrate 2x100Gb/s 20km fibre transmission achieving -25dBm sensitivity around 1340nm resulting in 33dB link budget. This is achieved by two EML-SOAs with 13.5dBm output power and negative chirp parameter to overcome chromatic dispersion, enabling the use of unassigned wavelengths in the O-band for 200G-PON.
