Advanced Test:
Test cable pair status, length, attenuation, reflectivity, impedance, skew and
another parameter.
Attenuation reflectivity:
After linking up, if reflectivity value is 0, it is the best quality
communication.
Impedance:
After linking 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.
