Publication number: 20100027954Abstract: This disclosure describes a fiber optic enclosure in which a cable entry port is sealed using a wedge that compresses a gasket that surrounds a fiber optic cable. As described herein, a fiber optic enclosure may include one or more entry ports through which fiber optic cables pass. As one of the fiber optic cables passes through one of the entry ports, the fiber optic cable passes through a gasket located in a receptacle behind the cable entry port. A wedge compresses the gasket, thereby compressing the gasket. When the gasket is compressed, the gasket exerts radial pressure on the fiber optic cable. In this way, the gasket forms a seal around the fiber optic cable.Type: ApplicationFiled: June 30, 2009Publication date: February 4, 2010Applicant: ADC TELECOMMUNICATIONS, INC.Inventors: Erik Gronvall, Dustin Tichy, Paula Rudenick
