Cable quality test:
Green is good quality cable, Yellow is Poor quality cable, Red is water poured
cable, the attenuation value will be displayed when cable over 10 meters.
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 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.
