Abstract

See full text

A method for connecting together two twisted pair lines in a LAN so as to avoid common mode current. The invention recognizes that the impedance to ground is different for each wire in the twisted pair line. Moreover, this impedance is different from spool-to-spool for lines having the same purported impedance. A balun is placed at the connection between the lines.
