What are the heat dissipation methods of the NDR module?

One is with "Finned Top" and the other is "Flat Top"; Generally speaking, the "Flat Top" module is mainly used on the NIC side, because the thickness of the NIC is limited. The "Finned Top" module has a module top design with heat dissipation fins, which can increase heat dissipation capacity and improve module performance and reliability in high-temperature environments. It is usually used in Quantum-2 and Spectrum-4 air-cooled switches.

What are the differences between OSFP-800G-2xSR4H and OSFP-800G-2DR4LH?

OSFP-800G-2xSR4H has a transmission distance of 100m and is typically used for 800G OSFP port switches. It can be connected to the opposite end of an 800G OSFP port switch or a 400G/200G OSFP ConnectX-7 port NIC to meet branching applications such as one-to-two or one-to-four connections. OSFP-800G-2DR4LH has a transmission distance of 500m and is usually used for interconnecting two 800G OSFP port switches.

Can this module be compatible with the NVIDIA QM9700 switch, and can you provide the corresponding test report?

Our product is perfectly compatible with NVIDIA QM9700/9790 devices. It undergoes 100% testing and inspection before shipment, and we can provide the corresponding test documentation.

Description

NVIDIA/Mellanox® MMS4X00-NS Compatible 800G 2xDR4/DR8 InfiniBand NDR Optical Transceiver Module(Twin-port OSFP, 1310nm, 100m, Two MPO-12/APC, DOM, for SMF, Finned Top)

NADDOD OSFP-800G-2xDR4H Optical Transceiver Module is an InfiniBand and Ethernet 800Gb/s 2x400Gb/s Twin-port OSFP, 2xDR4/DR8 single mode, parallel, 8-channel transceiver using two, 4-channel MPO-12/APC optical connectors at 400Gb /s each. The parallel single mode, data center reach 8-channel (2xDR4/DR8) design uses 100G-PAM4 modulation and has a maximum fiberreach of 100-meters using 8 single mode fibers. The Twin-port 2xDR4/DR8 transceiver is a key innovation with two internal transceiver engines enabling 64-ports of 400Gb/s in a 32-OSFP cage. The OSFP-800G-2xDR4H is used in Quantum-2 and Spectrum-4 air-cooled switches to switches, ConnectX-7 and BlueField-3 DPUs.

BER Testing

NADDOD optical modules exhibit a low bit error rate (BER). In LL FEC (272,257) testing, the 800G OSFP DR8 module demonstrates relative consistency with NVIDIA's original BER (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.
