Abstract

A novel optical fiber module attachment is provided. The module attachment has a crimp assembly and a fiber crimp tube disposed therein. The tube is crimped or otherwise fixedly attached to the core of the fiber optic cable. The fiber crimp tube has a shoulder that is fixedly captured within the crimp assembly, such that the core of the fiber optic cable does not exhibit movement relative to the connector. In accordance to another aspect of the invention, the module attachment is a fiber crimp tube having at least one shoulder thereon. The fiber crimp tube is crimped or otherwise attached to the fiber optic cable. The shoulder is fixedly received in receiving ports on an optical device. A heat shrink tube is optionally provided to connect an end of the tubular body to the cable to minimize the bend radius. The fiber crimp tube may also have an inner compression sleeve disposed between the fiber crimp tube and the core of the cable. The fiber crimp tube may also be covered by a water resistant material to protect the cable. Additionally, the fiber crimp tube may comprise two portions connected by a living hinge. The two portions may be attached to the fiber optic cable by a heat shrink sleeve an O-ring or a crimp tube.
