An optical connection closure has at least one connector port located within an external wall of the closure for receiving a connectorized optical fiber of a distribution cable on the inside of the closure and a pre-connectorized fiber optic drop cable on the outside of the closure. Each element is divided into sub-rows of sub-elements. Varying sputtering powers of the ferromagnetic metallic and non-magnetic oxide targets leads to various volume fractions of ferromagnetic metallic and non-magnetic oxide phases. The electromagnetic radiation damages the organisms and cells that cause disorders such as skin and nail infections and renders them substantially incapable of reproducing.
