Abstract
A fiber retention device is provided for retention of fibers such as optical fibers, tubing, cables, buffer tubes and other elongate objects. The retention device includes, generally, a mounting retainer and a resilient sleeve. The mounting retainer is formed of a resilient material and defines one or more generally U-shaped support channels. The resilient sleeve is positioned in the U-shaped support channel and defines at least one expandable passageway for receiving a fiber therein. The passageway diameter is less than the fiber diameter in a pre-load orientation or relaxed condition prior to inserting the fiber into the passageway. The support channel selectively includes a plurality of tabs for locating the sleeve therein including tabs on a bottom wall for resisting relative horizontal movement and tabs on a side wall for resisting relative vertical movement of the sleeve within the channel. The sleeve is positively located by the channel, and the fiber is retained and strain relieved by the elastomer sleeve. A mounting flange is provided for coupling a plurality of mounting retainers in a coupled orientation as desired.
