Abstract :
A computerized electromagnetic emission model has been developed to predict near-field radiation from unshielded copper wire that is used for asynchronous digital subscriber line (ADSL) transmission. The flat parallel wire is modeled as a combination of a large number of tiny dipole antennas. The twisted wire is modeled with bifilar helixes. Simulation results are presented for a drop wire configuration at customer premises and a single-section configuration in central offices (COs). Results are compared with FCC-recommended emission criteria
