Notes:

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 from the above table.
Measured with conformance test signal at TP3 (ref. IEEE 802.3 25GBASE-SR) for BER < 5∙10^-5
The test conditions are for measuring stressed receiver sensitivity only – not characteristics of the receiver.

FCC Class A Notice

This device 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 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 in a particular 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:
