800G QSFP-DD Optical Transceivers

800G QSFP-DD optical transceiver modules deliver next-generation high-density connectivity in the industry's most widely deployed form factor, purpose-built for AI/ML clusters, GPU interconnects, and hyperscale spine-leaf architectures. Supporting eight 100G electrical lanes with PAM4 modulation, each module delivers 800Gbps aggregate throughput per port at typical power consumption of under 15W - making them ideal for high-density 800G switching and AI fabric deployments where power budgets are critical.

Our 800G QSFP-DD transceiver portfolio covers the full range of data center reach requirements. The 800GBASE-SR8 module supports intra-rack and inter-rack links up to 100 meters over OM4 multi-mode fiber. The 800GBASE-DR8 module extends parallel single-mode connectivity up to 500 meters over OS2 fiber for campus and inter-building deployments. For longer-reach applications, the 800GBASE-2×FR4 module uses CWDM4-based dual-wavelength transmission to reach up to 2km over duplex OS2 single-mode fiber - ideal for data center interconnect and cross-building links.

Designed as a drop-in bandwidth upgrade, the QSFP-DD form factor delivers 800G throughput within the same footprint as legacy QSFP28 and QSFP56 deployments -minimizing infrastructure changes while doubling or quadrupling existing port capacity.

All 800G QSFP-DD modules are compliant with 800GAUI-8 electrical interface specifications and QSFP-DD MSA standards, ensuring broad compatibility with leading switch platforms, AI accelerators, and network interface cards from major vendors including Cisco, Arista, NVIDIA, and Broadcom-based systems.
