Fiber optic splice closures utilize various sealing methods, including mechanical, heat-shrinkable, breathable, and gel types, to ensure the safety of internal optical cables. The sealing strength is crucial for performance. . The Apex X-1 is a sealed splice closure designed for protecting optical fiber splices in both above- or below-grade applications in a butt configuration. The Apex X-1 is capable of up to 144* single fusion, 432 mass fusion with standard ribbon, or 864 mass fusion with “rollable ribbon” fiber types. Preparing cables for splice closures involves several steps that should be followed in the exact sequence specified by the manufacturer to ensure the cables are properly secured with adequate strain relief and the closure will seal. The cable jacket (or sheath) and strength members of the cable. FOSC, or Fiber Optic Splice Closure, is a specialized protective enclosure specifically engineered to safeguard fiber optic splices – the critical junction points where individual optical fibers are permanently joined together.
