Radio permitting information transfer between radio frequency shielded sub-systems

摘要

A radio (300) includes shielded circuitry (318) residing within radio frequency electromagnetic shielding structure (320) that has an aperture (322) formed therein. The shielded circuitry includes an optical transmitter (206) to direct light (information) through the aperture to an optical detector (208) coupled to other circuitry residing outside of the electromagnetic shielding structure. In this way, the optical detector receives light (information) from the optical transmitter via the aperture without degrading the radio frequency shielding of the shielded circuitry.
