In this look at transmission line theory, we will assume an RG-58 type of coaxial cable which has a characteristic impedance of 50 Ω. Where we let C stand for the capacitance per unit length, 30 pF ...

Optical time domain reflectometry (OTDR) has long been instrumental in analysing the integrity of optical fibre networks by detecting backscattered light from imperfections and disturbances along the ...
