Attenuation reflectivity:
After link up, if reflectivity value is 0, it is the best quality communication.
Impedance:
After link up, if the impedance value is 100
Ω
, it is the best quality communication, the
range is generally in 85-135
Ω
.
Skew:
After 1000M link up, when skew value is 0ns, it is the best quality communication, if over 50ns,
will cause a Bit Error Rate in the transmission.

Cable sequence diagram:
It shows a straight-through and cross-over cable diagram, the cable sequence display for reference.
