Lines: 20 >>I really want to know what the guts of a 'thin-net' terminator are. A theoretical or ideal thin-net transmission line has a characteristic impedence of 50 ohms at all frequencies. It also has infinite length. In order to make a real line look ideal, it is terminated at the end with a resistor, preferably carbon film or carbon composition. Any other form such as wire wound types would have varying impedance across the frequency spectrum. Since the characteristic impedance of 'thick' ethernet is the same, the internals are roughly the same.
