Calculating Optical Cable Length Based on Twist Factor
Approaching it from a geometrical standpoint the helical length equation, $L = sqrt {H^2+pi^2D^2} $. Where L is the length of wire needing to be cut, H is the desired end length, D is the diameter from each wire core center. Example: If a cable drawn on the map is 3,000 feet long and there are 2 slack loops where each. This Applications Engineering Note (AE Note) addresses estimating cable length or event distance using an optical time domain reflectometer (OTDR). This AE Note does not provide operating instructions for any particular OTDR. I'm considered factors such as AWG, insulation thickness, and how many twists per inch (ranges from 1. In this paper, a family of equations has been developed to describe the behaviour of twisted pair cables as functions of cable dimensions, basic material parameters and frequency of operation. These equations allow the prediction of secondary parameters without the need to extrapolate from. There are a number of ways to tackle the problem of determining the power requirements for a particular fiber optic link.
