NEXT Loss (Near End Crosstalk) | Velocity of Propagation (VoP) |
FEXT Loss (Far End Crosstalk) | TCL and TCTL (optional) |
Crosstalk Power Sums | Transfer Impedance (optional) |
Structural Return Loss (SRL) | Screening Attenuation (optional) |
Return Loss (RL) | Capacitance and Resistance |
Propagation Delay and Delay Skew | Capacitance Unbalance |
Impedance (Input and Characteristic) | Resistance Unbalance |
