Data handling capacity of a real transmission line in a noiseless system

A computation technique is described for determining the maximum error-free data rate for a transmission line whose attenuation and phase shift have been measured at discrete frequencies. Results are calculated using the manufacturer's measurements of commercially available twisted pair lines of American Wire Gauges (AWGs) 19, 22, 24, and 26, for lengths up to about 5 km and assuming an unloaded uniform line. The results highlight the importance of the phase data and show the deficiencies in both quantity and accuracy of the experimental data available.<
