CAT6 Gauge and Return Loss

Return Loss
I am using two gauges, 23AWG and 24AWG and found that Return losses are better in 24AWG. Is there a reason, as impedance is pretty much the same?

Thanks. We'll let you know when a new response is added.

A 23AWG cable is 0.57mm wide, while a 24AWG cable is only 0.52mm wide. So the SMALLER the number, the LARGER the physical cable will be, with more copper inside it. increasing the diameter of the cable is a way to reduce resistance over the cable and achieve better electron flow.

    Without knowing anything about the signal, there's not much we can say other than that the 24AWG is apparently a better match for whatever the load is.

    If understood correctly, go for  24AWG gauges.

    Perhaps a look at Litz wire may be worth a look when considering high frequency transmissions, as far as I know twisted pair cables do not contain Litz but this wire characteristic confounds the idea that larger diameter is "faster". the theory is that high frequency electrical transmission is carried on the surface of the conductor, not through the core. Admittedly larger diameter conductors have a larger surface area.
