A termination is provided for a differential transmission line such as unshielded twisted pair (UTP) to isolate a connected device from electromagnetic interference present on the UTP in the form of differential mode and common mode noise. An example of an electromagnetic interference isolator comprises a common mode and a differential mode termination (24, 25), a common mode choke (26) which exhibits substantially constant impedance over a wide bandwidth and a centre tapped isolation transformer (27).
