The QSFP-DD 400G Digital Coherent Optical (DCO) 0dBm Open ZR+ transceiver is a 400 Gbit/s multirate pluggable module for 100/200/300/400GBASE Ethernet optical data communication. ZR+ supports multiple configuration options in terms of modulation scheme, shaping, and baud rates to support different network topologies and allows longest transmission distance (> 120 km). With data rate increases. ble coherent optics in QSFP-DD format. It offers enhanced optical performance compared to 400ZR by utilizing high-gain forward error correction (FEC), flexible 100G–400G line rates, and support for extended reaches through multiple mo ulation types (16QAM, 8QAM, and QPSK). In 400G/16QAM mode. The 400G QSFP-DD ZR+ is designed to 100G/200G long haul and 300G/400G Metro IP over DWDM applications without inline chromatic dispersion compensation. 400G DP-16QAM modulation format. The 400G QSFP-DD. ZR+, Standard Tx output power (-10dBm), C-band tunable, Pull tab, 0°C to 70°C, LC receptacle The emerging OIF 400ZR and Open ZR+ MSA coherent transceivers in QSFP-DD and OSFP form factors generally have low transmit output power (-10 dBm), making them incompatible with ROADM networks. It features standard 19” 1U, 2U, 4U chassis, power supply (AC/DC optional), 1+1 backup, ready to install.
