Abstract

A strain relief assembly is provided for use in management of optical fibers that enter and exit the enclosure walls of optical fiber components, such as optical amplifiers, etc. The strain relief assembly includes a rigid plastic sleeve, and an elastomeric boot. The boot includes a main body portion having retaining shoulders located on opposing sides of a retaining channel, and further includes a cone-shaped tip portion to guide and support the optical fiber as it exits the wall of the enclosure. The retaining shoulders and retaining channel cooperate to lock the boot into a U-shaped opening in a wall of an enclosure. The main body portion of the boot includes an axial opening for receiving the sleeve and the cone-shaped tip portion includes an co-axially extending bore for receiving the optical fiber. The sleeve is a cylindrical rigid tube configured for receiving the optical fiber therethrough. In use, the fiber is fixed in place inside the sleeve with a UV curable resin. To facilitate the use of such UV curable resins, the sleeve is made of optically transparent material and the boot also includes a window to allow UV light to pass through the boot to the sleeve.
