Minimum assembly bending radius (close to the connector) is 10x the cable’s outer diameter. The repeated bend (far from the connector) is also 10x the cable’s outer diameter. The single bend (far from the connector) is 5x the cable’s outer diameter.
**’Combined’ end is the ‘head’ where the cables join together, inserted into the switch. ‘Single’ end is the ‘tail’ which plugs into the HCA/NIC in a server.
L = Assembly Space. Minimum value depends on the backshell (connector housing) dimensions = the space for the cable assembly behind the rack door.

Ask your NVIDIA FAE for a zip file of the certifications for this product.
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense.
Handling Precautions and Electrostatic Discharge (ESD)
The cable is compatible with ESD levels in typical data center operating environments and certified in accordance with the standards listed in the Regulatory Compliance Section. The product is shipped with protective caps on its connectors to protect it until the time of installation. In normal handling and operation of high-speed cables and optical transceivers, ESD is of concern during insertion into the QSFP cage of the server/switch. Hence, standard ESD handling precautions must be observed. These include use of grounded wrist/shoe straps and ESD floor wherever a cable/transceiver is extracted/inserted. Electrostatic discharges to the exterior of the host equipment chassis after installation are subject to system level ESD requirements.
Cable Management Guidelines
It is important to follow the instructions and information detailed NVIDIA Cable Management Guidelines and FAQ Application Note to insure proper and optimal installation of this cable and avoid physical damage.
