Which formula calculates total loss in a cable system?

The formula that accurately calculates total loss in a cable system is the sum of insertion loss and total cable loss. Insertion loss refers to the reduction in signal strength that occurs when a signal is introduced into a transmission line, typically from connectors or splices. Total cable loss accounts for the degradation of the signal due to the attenuation properties of the cable over its length as well as any other passive components that contribute to signal loss.

Incorporating both factors provides a comprehensive view of the total loss incurred in a cable system, reflecting both the inherent characteristics of the cable and the losses incurred during signal insertion. This understanding is crucial for maintaining optimal signal integrity in broadband systems and ensuring that the final output meets required specifications.
