Chirp control in directly modulated 25G PAM4 transmitters for optical access networks
Dalla Santa, Marco
Townsend, Paul D.
Narrowband filtering chirp control is demonstrated for a 25Gb/s PAM4 signal in directly modulated transmitters for next generation optical access systems, allowing 50km transmission without chromatic dispersion compensation with blue-shift filtering offering the best performance.
