The far-infrared transmission spectra for high-conductivity Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8} films with the radiation polarized in the {ital ab} plane have been measured for temperatures above and below {ital T}{sub {ital c}}. The normal-state properties show a Drude-like response. The transmission spectrum can be used to derive both the dc conductivity (90 {mu}{Omega} cm at {ital T}{sub {ital c}}) and the relaxation rate (165 cm{sup {minus}1} at {ital T}{sub {ital c}}). If an energy gap at 3.5{ital kT}{sub {ital c}} or higher is assumed then the film is in the clean limit. In the superconducting state the transmission drops at low frequency but remains finite.
