The RuggedRouter provides a method to account for this delay. The table below
gives some examples of the delay that can be expected for a given dielectric type.
Please note that cable characteristics varies from one manufacturer to the other.
Dielectric Type Time Delay in ns/m (ns/ft)
Solid Polyethylene 4.62 (1.54)
Foam Polyethylene (FE) 3.81 (1.27)
Foam Polystyrene (FS) 3.36 (1.12)
Air Space Polyethylene (ASP) 3.45-3.63 (1.15-1.21)
Solid Teflon (ST) 4.38 (1.46)
Air Space Teflon (AST) 3.39-3.60 (1.13-1.20)
