Specifications
Absolute maximum ratings are those beyond which damage to the device may occur.
Prolonged operation between the operational specifications and absolute maximum ratings is not intended and may cause permanent device degradation.

Notes:
Average launch power, each lane (min) is informative and not the principal indicator of signal strength.
Even if TDECQ < 1.4dB, OMAouter (min) must exceed this value.
Transmitter reflectance is defined looking into the transmitter.
Receiver sensitivity (OMAouter), each lane (max) is informative and is defined for a transmitter with SECQ of 0.9 dB.
Measured with conformance test signal at TP3 for the BER = 2.4x10-4.

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.
