Description NADDOD QDD-400G-ZR Pro is a C-band optical frequency-tunable coherent optical transceiver that combines 7nm coherent DSP ASIC functionality with best-in-class ultra-narrow-linewidth tunable lasers, high-speed modulators, and high-responsivity coherent receivers to deliver high performance at 100G DP-QPSK, 200G DP-QPSK, 300G DP-8QAM, and 400G DP-16QAM modulation formats. With an EDFA and VOA inside the TX optical path, the output optical power is tunable from –10 to 1 dBm; in 400G Grey Light mode (193.7 THz), the output power is 4 dBm.
The 400G QSFP-DD ZR+ Pro is designed for 100G/200G long-haul and 300G/400G metro IP over DWDM applications without inline chromatic dispersion compensation. It is suitable for 400G Ethernet data center solutions over distances of up to 120 km, supporting DCI edge and regional interconnections. It can be deployed in a variety of network topologies, including point-to-point, star, and ring networks.
