Advanced Test: Test cable pair status, length, attenuation, reflectivity, impedance, skew and other
parameters.
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 100Ω, it is the best quality communication, the
range is generally in 85-135Ω.
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.
