3m (10ft) NVIDIA/Mellanox Compatible 800G OSFP 8 x 100G PAM4 RHS/Flat Top InfiniBand NDR Passive Copper Twinax Cable

The NVIDIA/Mellanox InfiniBand compatible 800G OSFP (Octal Small Form-factor Pluggable) direct attach cable operates over passive copper, which requires no additional power to ensure quality connectivity. This cable is compliant with OSFP MSA (Multi-Source Agreement), CMIS Rev5.0, and IEEE 802.3ck standards. Featuring a RHS/flat top OSFP design, it is specifically designed for use in DGX H100 systems.
DAC cables are the lowest-cost, lowest-latency, near zero power consuming high-speed links available due to their simplicity of design and minimal components. They are ideal for short-distance interconnections within telecom or data center equipment rooms, offering a power-efficient and cost-effective connectivity solution.
Note: "Finned top" transceivers are now called "Integrated Heat Sink" (IHS) as the cooling fins are integrated into the OSFP connector metal top. Commonly used in air-cooled switches.
"Flat top" transceivers are now called "Riding Heat Sink" (RHS) as the cooling fins ride on top of the network card or system's internal cages. This is used for both air-cooled and liquid-cooled applications for DGX, ConnectX-7, and BlueField-3 DPUS.
