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.
