Below depicts a 100m 3-pair STP cable, where my focus is the pair 1 on the top:
If I know the output impedance of the source Rs, and if I want to calculate the LP filter effect of the cable on the V1 signal; how can I calculate the total capacitance C1 for the Pair 1.
How can I calculate the total capacitance of the pair from the data-sheet like this one? Which parameters should be taken into account?
(Consider the signal frequency V1 is low like 100Hz(sinusoidal), I guess we can neglect the transmission line effects)
