Description NADDOD Ciena 180-3530-900 Compatible QSFP-DD 400G ZR is a C-band, frequency-tunable coherent optical transceiver. It integrates a 7 nm coherent DSP ASIC with best-in-class ultra-narrow linewidth tunable lasers, high-speed modulators, and high-responsivity coherent receivers to deliver high performance using 400G DP-16QAM modulation. The module is designed for 400G DWDM data center interconnect (DCI) applications, supporting up to 40 km unamplified transmission without inline chromatic dispersion compensation.
The QSFP-DD 400G ZR is widely deployed in hyperscale data centers to enable high-performance edge interconnection. It supports multiple network topologies, including point-to-point, star, and ring architectures.
