Over 60GHz InP CDM and ICR Enabling 800Gbps LR/ER/ZR/ZR+ Transmission Links With 120Gbaud/DP-16QAM Modulation

By using >60GHz 3dB bandwidth InP coherent driver modulator (CDM) and intradyne coherent receiver (ICR), we have demonstrated a record ≤13.6dB link budget for 800LR/ER, an rOSNR of 27dB for 600-km 800ZR+, and an 800ZR link accommodating optical line protection with a >20dB fiber loss budget. © 2021 The Author(s)
