12.1.1 How to Calculate the Maximum Recommended Length
For cables not in Table 19, you can determine the maximum length of cable between
transponders using the cable’s mutual capacitance, which is provided by the cable
manufacturer.
Capacitance
Capacitance is the ability of a system to store an electric charge when a potential difference
exists between its conductors. Capacitance is measured in farads (F). A system that is
charged with 1 coulomb of energy and that has a potential difference of 1 volt between its
conductors has a capacitance of 1 farad.
