ABSTRACT:
A strain relief boot for attachment to an optical fiber or fiber containing cable has a mounting section and a tapered section extending therefrom with a smooth bore extending to the exit end of the tapered section. The exit or distal end of the tapered section has formed therein a curved funnel shaped portion, the curve of which is faired into the bore. The radius of curvature of the funnel is greater than the critical bend radius of the fiber or fiber cable and protects the fiber or cable exiting the boot from bending too sharply. The tapered section has a plurality of transverse slots which increase flexibility of the tapered section, but which limit the bend radius thereof under side loading to a value greater than the critical bend radius of the fiber or fiber cable. The mounting section is formed with a ridge or ridges for effectively attaching the boot to a connector.
