200Gb/s Bi-Directional TDM-PON with 29-dB Power Budget

We demonstrate the first 200-Gb/s (100-GBaud PAM-4) TDM-PON using directly modulated lasers and direct detection. We achieve >29-dB link power budget by combining distributed Raman amplification over 21-km fiber and an SOA-based pre-amplifier.
