NVIDIA Optical Transceivers: QSFP-DD/OSFP Solutions and Compatibility Overview
November 6, 2025
In the era of artificial intelligence and high-performance computing, data center networks require unprecedented bandwidth and low-latency connectivity. NVIDIA's optical transceiver solutions are at the forefront of this technological revolution, enabling 800G data transmission through advanced form factors like QSFP-DD and OSFP.
Both QSFP-DD (Quad Small Form-factor Pluggable Double Density) and OSFP (Octal Small Form-factor Pluggable) represent the cutting edge of optical transceiver technology, designed to support 800G Ethernet and beyond. While they share the common goal of high-density, high-speed connectivity, each offers distinct advantages for different deployment scenarios.
- QSFP-DD: Backward compatible with existing QSFP28 and QSFP+ infrastructure, supporting data rates from 400G to 800G
- OSFP: Optimized for higher power budgets and future 1.6T capabilities, with enhanced thermal performance
- 800G readiness: Both form factors support the latest 800G optical standards
NVIDIA's optical modules deliver exceptional performance characteristics that make them ideal for AI workloads, cloud computing, and high-frequency trading applications. The 800G-capable transceivers support various reach options from short-reach multimode to long-haul single-mode applications.
| Parameter | QSFP-DD 800G | OSFP 800G |
|---|---|---|
| Data Rate | 800 Gbps | 800 Gbps |
| Power Consumption | <14W | <16W |
| Max Reach | 10km | 10km |
| Backward Compatibility | QSFP28, QSFP+ | OSFP-only |
NVIDIA optical transceivers with QSFP-DD/OSFP support are transforming data center interconnects. These solutions provide the foundation for scalable AI infrastructure, enabling seamless communication between GPUs, switches, and storage systems.
The 800G capability is particularly crucial for distributed AI training workloads, where massive datasets need to be transferred between computational nodes with minimal latency. NVIDIA's comprehensive testing ensures full compatibility across their networking product portfolio.
As network demands continue to grow, both QSFP-DD and OSFP form factors are evolving to support even higher data rates. The industry is already looking toward 1.6T solutions, with NVIDIA positioned to lead this transition through continued innovation in optical technology.
For organizations planning their network infrastructure roadmap, understanding the compatibility and performance characteristics of these optical modules is essential for making informed investment decisions.
