ABSTRACT:
A splice protection sleeve including rigid strength members and a melt-flow plastic adhesive inner tube member contained within a heat shrinkable outer tube member. The strength members are positioned on either side of the inner tube. In use, multiple optical fibers are inserted into the inner tube and fusion spliced. Upon the application of heat to the fusion splice protection sleeve, the heat shrinkable outer tube contracts around the strength members and inner tube and the inner tube melts filing vacant areas within the outer tube. Upon cooling, the melt-flow adhesive binds the strength members, multiple optical fibers and outer tube of the fusion splice protection sleeve. Because the melt-flow adhesive inner tube containing the optical fibers is sandwiched between the strength members, upon heating and cooling of the fusion splice protection sleeve, the outer tube substantially maintains its original cross-sectional geometry, applying evenly distributed forces to the multiple optical fibers.
