What is the difference between 74% NVP and 75% NVP?

NVP stands for Nominal Velocity of Propagation. It’s a measure used in telecommunications to describe the speed at which an electrical signal travels through a cable relative to the speed of light in a vacuum.
NVP is expressed as a percentage, indicating how fast the signal moves compared to the speed of light.
For example, an NVP of 75% means the signal travels at 75% of the speed of light. This metric is crucial for ensuring accurate signal timing and performance in network installations.
In layman's terms the difference in length at 90 meters between 74% and 75% Nominal Velocity of Propagation (NVP) can be calculated using the formula:
Length=NVPMeasured Length
So, the difference in length at 90 meters between 74% and 75% NVP is approximately 1.62 meters.
