Can I use 800G OSFP optical modules for 800G QSFP-DD ports?

No, OSFP and QSFP-DD are different size packages, the physical size is not the same, and they are not compatible.

Can modules with the same rate and different packages be interconnected, such as OSFP and QSFP-DD?

OSFP and QSFP-DD are just the physical form factor of the modules, as long as the modules belong to the same type (e.g. both DR4 or FR4), they can be interconnected.

Description

NVIDIA/Mellanox® Compatible 800G 2xFR4/FR8 InfiniBand NDR Optical Transceiver Module(Twin-port OSFP, 1310nm, 2km, Two LC Duplex, DOM, for SMF, Finned Top)

NADDOD OSFP-800G-2xFR4H Optical Transceiver Module is designed for 800GBASE throughput up to 2km over single-mode fiber (SMF) with dual duplex LC connectors. The OSFP-800G-2xFR4H can convert 8-channel 106.25Gb/s electrical data to 8-channel 106.25Gb/s optical signals. Similarly, it optically converts 8-channel 106.25Gb/s optical signals to 8-channel electrical data output on the receiver side. It has been designed to withstand the maximum range of external operating conditions including temperature, humidity and EMI. The OSFP-800G-2xFR4H Optical Transceiver is a high performance, cost effective Module for optical data communication applications supporting 800G InfiniBand and Ethernet.

Switch2 Testing

Connectivity Testing

The optical module establishes a reliable connection between devices and demonstrates robust performance. Throughout the entire testing phase, both device ports consistently maintained optimal operating conditions, with no errors or interruptions observed.
BER

Switch1 Testing
Switch2 Testing

BER Testing

NADDOD optical module exhibits a low bit error rate (BER). During LL FEC (272,257) testing, the 800G OSFP FR8 module demonstrates a relatively consistent BER with NVIDIA's original specifications (maintaining a BER around -8~-10) 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

Can I use only one port of the 800G dual-port NDR 2xFR4 optical module?

Yes, if only one of the ports is used, the rate is 400G.

What are the advantages of Finned Top optical modules?

"Finned top" refers to the design of the top of the module with finned tops, which increases the heat dissipation capacity and improves the performance and reliability of the module in high temperature environments. The fins are usually arranged in a thin sheet-like structure, similar to a heat sink, to increase the surface area for better heat dissipation.

Can this module be connected to 400G modules?

Yes, this OSFP-800G-2xFR4H optical module can be connected to two 400G FR4 optical modules via two single-mode fiber patch cables.
