The growing usage and application of high-speed communication networks together with high population density, demand the installation of high-fiber count optical fiber cable networks. However, the currently available optical fiber splice closures are deemed bulky and their installation complex and time consuming. The mini closure is acid and alkaline resistant. Furthermore, its airtight, waterproof design makes it ideal for applications in a damp environment. Since the casing material is recyclable, environmental pollution is minimized. The ease of installation is evident, a screwdriver is all you need from start to finish. In addition, for loose tube applications no heat shrinking work is required.
