Advanced Test:
test cable pair status, length, attenuation, reflectivity, impedance, skew and
other parameter.
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.
