Product Highlights

Enhancing Mid-Range Data Transmission Stability in AI-Driven InfiniBand Networking

Powered by Broadcom 7nm DSP chip, NADDOD 800G OSFP 2×DR4/DR8 offers superior process maturity, hardware reliability, and multi-ecosystem compatibility. Advanced DSP equalization compensates for optical link impairments, ensuring stable mid-range transmission and reducing operational complexity. In the RS-FEC(272,257+1) test, NADDOD 800G OSFP DR8 achieve pre-FEC BER of -8~-11, and near-zero post-FEC BER, ideal for real-time AI training and large-scale cluster computing.

Exploring More Diverse and Cost-Effective Solutions for AI Clusters

800G OSFP DR8 provides a cost-optimized, scenario-based connectivity solution for data centers. Utilizing low-cost DACs for efficient short-distance intra-rack connections reduces the need for intermediary devices and costs. For inter-rack transmissions, a module and patch cable approach ensures stable, high-speed data transmission. The flexible deployment solution balances performance and costs across varying transmission distances, effectively lowering the total cost of ownership (TCO) and deployment complexity. It offers a high-performance, cost-effective interconnect solution suitable for all scales of architecture, accelerating the efficient deployment and optimization of AI clusters.

BER Testing

NADDOD optical modules exhibit a low bit error rate (BER). In RS-FEC(272,257+1) test, the 800G OSFP DR8 module demonstrates relative consistency with NVIDIA's original BER (maintaining a BER around -8～-11) before error correction, while achieving near-zero BER after error correction. Maintaining a low BER helps to avoid link instability caused by high error rates, ensuring the stability of cluster performance and large-scale model training. This contributes to simplifying customer operations and maintenance while reducing costs.

Questions & Answers

Ask a Question

Q:

Can I connect this module to 400G modules?

A:

Yes, this OSFP-800G-2xDR4 optical module can be connected to two 400G DR4 optical modules via two 12-core single-mode fiber patch cables.

Q:

what are the differences of heat dissipation methods about OSFP-800G-2xDR4H, OSFP-800G-2DR4LH, OSFP-800G-2DR4FH?

A:

OSFP-800G-2xDR4H、OSFP-800G-2DR4LH are finned top modules, which have the module top design with heat dissipation fins, increasing heat dissipation capacity and improving module performance and reliability in high-temperature environments. These modules are usually used in Quantum-2 and Spectrum-4 air-cooled switches. OSFP-800G-2DR4FH is a flat top module, which is mainly used on the NIC side, because the thickness of the NIC is limited.
