Abstract
The fiber optic interconnection enclosure, such as a fiber optic distribution frame or the like, effectively limits the entry of particles, such as dust and other contaminants, into the enclosure. For example, the fiber optic interconnection enclosure can maintain a greater pressure, i.e., a positive pressure, within the internal cavity defined by the enclosure than outside of the internal cavity so as to effectively limit the entry of particles into the internal cavity, even as the door of the fiber optic interconnection enclosure is repeatedly opened and closed. The fiber optic interconnection enclosure generally includes at least one fan to draw air into the internal cavity through an air inlet port defined by the cabinet and to circulate the air through the internal cavity in order to reduce the number of particles that settle upon or are transferred to the end faces of the optical fibers or other surfaces within the internal cavity. By filtering the air drawn into the internal cavity, at least some of the particles are removed from the air drawn into the internal cavity. In addition, by expelling at least some of the air that has circulated within the internal cavity through a…
