Note: Minimum insertion loss for up to 1m cable length is 6dB @ 12.89GHz.
The head-end of the MCP7F60 cable is QSFP-DD. Hence the memory map of its EEPROM is formatted in compliance with CMIS 4.0 [1]. The key parameters are listed below. The EEPROMs of the QSFP ‘tails’ are SFF-8636 [4] compliant. The memory map of the QSFPs is found in the QSFP56 Memory Map – SFF-8636 compliant - I2C Address A0h table further down .

Regulatory Compliance and Classification
The MCP7H60 is qualified in accordance with the following standards:
Safety: CB, UL, CE
EMC: CE, FCC, ICES, RCM, VCCI
Ask your NVIDIA field engineer or the support team for a zip file of the certifications for this product.
FCC Class A Notice
Each of the devices complies with CFR47 FCC Class A Part 15 of the FCC Rules. Operation is subject to the following two conditions:
This device may not cause harmful interference.
This device must accept any interference received, including interference that may cause undesired
Note: 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 in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur during installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
Consult the dealer or an experienced radio/television technician for help.
Modifications: Any modifications made to this device that are not approved by NVIDIA may void the authority granted to the user by the FCC to operate this equipment.
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.
