Real-Time 20 and 25 Gbit/s Pre-Equalized C-band Transmission With Electrical Duo-binary Detection

We experimentally demonstrate real-time C-band transmissions with up to 29 dB optical budget after 25 km propagation at 20 Gbit/s and 25 Gbit/s. Our solution uses pre-equalization and electro-optical components dedicaded for 10 Gbit/s transmissions.
