Notes:

  1. The receiver may not operate correctly at this input power level.

  2. All Tx channels on and all Rx channels on with AOP 3dB greater than the tested channel. Injected optical eye must comply with the transmitter eye mask definition.

  3. Measured with conformance test signal at TP3 (ref. IEEE 802.3 100GBASE-SR4) for BER < 5E-5.

  4. The test conditions are for measuring stressed receiver sensitivity only – not characteristics of the receiver.

This product 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 all connectors to protect it during shipping. In normal handling and operation of high-speed cables and optical transceivers, ESD is of concern during insertion into the OSFP 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.

The transceiver can be damaged by exposure to current surges and over voltage events. Take care to restrict exposure to the conditions defined in Absolute Maximum Ratings. Observe normal handling precautions for electrostatic discharge-sensitive devices. The transceiver is shipped with dust caps on both the electrical and the optical port. The cap on the optical port should always be in place when there is no fiber cable connected. The optical connector has a recessed connector surface which is exposed whenever it has no cable nor cap.

Prior to insertion of the fiber cable, clean the cable connector to prevent contamination from it. The dust cap ensures that the optics remain clean and no additional cleaning should be needed. In the event of contamination, standard cleaning tools and methods should be used. Liquids must not be applied.

The transceiver’s memory map is compliant with the QSFP Management interface specification SFF-8636. See also the NVIDIA LinkX® Memory Map Application Note (MLNX-15-5926).

The following label is applied on the transceiver's backshell:

Ask your NVIDIA FAE for a zip file of the certifications for this product.

Each of the devices complies with CFR47 FCC Class A Part 15 of the FCC Rules. Operation is subject to the following two conditions:

  1. This device may not cause harmful interference.

  2. This device must accept any interference received, including interference that may cause undesired operation.

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.
