Which formula is used to calculate total cable loss?

Total cable loss refers to the signal loss that occurs over a length of cable due to various factors, including resistance and the quality of materials used in the cable. The appropriate formula for calculating total cable loss is grounded in the relationship between the length of the cable and the intrinsic loss characteristics of the cable itself.

When you multiply the cable footage (the total length of the cable) by the cable loss (the loss per unit of length), you derive the total loss that will affect the signal as it travels through the entire length of the cable. This multiplication accounts for how longer cables will typically result in higher losses due to the cumulative effect.

Thus, the formula for total cable loss — cable footage multiplied by cable loss — is mathematically sound and reflects the physical principles governing the behavior of signals within cables. By using this formula, an installer can accurately predict how much signal strength will be lost over a given distance, which is critical for ensuring proper installation that meets performance standards.
