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 $\leq$ 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) OCIS codes: (060.1660) Coherent communications; (060.2360) Fiber optics links and subsystems
