Why Choose This Product?

• 800Gb/s XDR bandwidth – Provides the bandwidth class required for next-generation AI and HPC fabrics.
• 4×200G-PAM4 optical design – Uses four high-speed optical lanes to deliver the specified 800Gb/s aggregate rate.
• 500m single-mode reach – Gives data-center architects greater flexibility for switch-to-server and fabric connectivity.
• OSFP DR4 form factor – Fits high-density 800G optical networking architectures designed around OSFP interfaces.
• MPO-12/APC connectivity – Provides a standardized multi-fiber interface for supported 4-channel optical links.
• XDR-specific positioning – Designed for 800G XDR rather than being positioned as a 400G NDR optic.
• AI infrastructure ready – Appropriate for supported high-bandwidth GPU and accelerator networking environments.
• NVIDIA ecosystem alignment – Designed as part of NVIDIA's 800G XDR optical portfolio for supported infrastructure.
