Dispersion tolerance of 100-Gbit/s PAM4 optical link utilizing high-speed avalanche photodiode receiver

For the purpose of developing a 4λ × 100-Gbit/s PAM4 10-km optical link, the dispersion tolerance through single mode fiber was experimentally investigated with a high-speed avalanche photodiode (APD) receiver. The power penalty was less than 1 dB over the LAN-WDM dispersion range.
