Key Features
400G technology is the next generation of high-speed optical transceivers designed to meet exploding bandwidth demands from AI, cloud, and massive data center traffic. It offers superior efficiency (power per bit) and density compared to aggregating multiple 100G links. The QSFP-DD form factor is a dominant industry choice, utilizing eight electrical lanes operating at 50 Gbps each with PAM4 modulation to aggregate to 400 Gbps.
