Zoom

• Quickly Repair Broken or Damaged Fiber
• Available with FC/PC, FC/APC, or LC/PC Connector
• Scissor Cut on the Spliceable End
• Wavelength Range: 1260 - 1620 nmi
• Includes 60 mm Splice Protector Sleeves

Our splice-on fiber connectors offer the quickest pre-polished terminated pigtail in order to prepare the end splice; there is no polishing or epoxy necessary. To splice, simply strip the jacket off of the spliceable end, cleave, and splice together with the prepared end of the broken or damaged fiber. The image in the Overview Tab above shows our splice-ready fibers mounted in a fiber splicer. Splice sleeves are also included to protect the splice joint of the fixed fiber. Each package comes with six splice-ready fiber connectors and six splice sleeves. Extra splice protector sleeves are available below.

Thorlabs’ Splice Protector Sleeves are designed to protect splices in fibers with an outer diameter up to 900 µm. These fusion splice protector sleeves are an economic solution that offers reliable and solid protection for splice joints. An outer shrink tube holds the tube through which the fiber is threaded as well as the strength member, a solid steed rod that provides rigid support for the splice joint. This design not only provides a replacement for the original fiber cable jacket, but also provides excellent rigidity around the splice joint, preventing the spliced area from bending or flexing.

To use, thread the fiber through the inner fiber tube of the sleeve. Position the sleeve so that the splice joint is in the middle. The sleeve must then be heated causing the outer shrink tube to contract to Ø3.2 mm. Proper heating is required to ensure an accurate fit and function of the splice protector sleeve. The image to the left illustrates the effects of proper and improper heating on these sleeves. The top image shows normal heating; here the shrink tube is uniform across the splice, providing permanent and rigid protection. The middle image shows excessive heating; here the shrink tube shows evidence of blemishes and melts in the tubing. The bottom image shows insufficient heating; here the shrink tube is not uniform across the splice, resulting in loose or poor protection for the splice joint. A fiber splicer can be used to ensure proper heating of the sleeve (refer to the operation manual of your splicer for correct heating settings). The image to the right shows a properly heated splice protector sleeve in a fiber splicer (see Splice Sleeve Guide tab for more information).

The clear outer tube of the splice protector sleeves allows the color of the optical fiber itself to be seen. These sleeves come in two standard sizes of 40 mm and 60 mm. They cannot be cut due to the steel rod that provides support for the splice joint. Custom lengths are available; please contact Tech Support for more information.
