What is a "normalised" cable distance?

To enable a calculation of the expected performance, the "normalised" cable distance is calculated using an algorithm to provide an equivalent performance for 0.40 gauge cable.

Thicker gauge cable (eg 0.64 0.81 etc) has a lower attenuation of the signal frequencies and as such you can get similar results over a greater distance when compared with 0.40 gauge copper. Similarly when the wire gauge is smaller than 0.40 (eg 0.32) then the algorithm increases the equivalent 0.40 (normalized) cable length to take into account the greater attenuation of the signal frequencies of the thinner wire.

The bottom line is that the normalised distance should be used estimate service quality as this provides a consistent, normalised result that can be used for expected attenuation, noise etc.
