For more information about the conditions used for the stressed receiver tests, and other
information, see the IEEE 802.3aq standard.
The following table (from IEEE 802.3aq) describes the maximum channel insertion loss. The
channel insertion loss includes both attenuation and connector loss (1.5 dB); therefore the
maximum fiber attenuation is 0.2 to 0.4 dB.
