Fiber Splice Closure Applications
FTTx Network Deployment: Protecting splices at distribution points, closures, and terminal ends in fiber-to-the-home/building/curb networks.
Long-Haul & Metro Telecom: Sealing and organizing splices in underground ducts and aerial cables along backbone and metropolitan ring networks.
CATV & Broadband Expansion: Securing optical node and distribution splices for hybrid fiber-coaxial (HFC) network upgrades and expansions.
Industrial & Railroad Communications: Providing ruggedized protection for fiber links in harsh industrial settings and alongside transportation corridors.
SHENGWEI Fiber Closure Advantages
Material Science Expertise: We use engineering-grade polycarbonate or ABS materials, UV stabilized for long-term outdoor performance.
Rigorous Sealing Validation: Every closure design undergoes pressure, water immersion, and thermal cycling tests to guarantee IP68 performance.
Design for Deployment Efficiency: Our closures feature intuitive cable entry ports, modular splice tray stacking, and clear labeling to minimize field labor time.
Global Project Compliance: Products are designed to meet key international standards (GR-487, ITU-T, Telcordia) for telecom-grade reliability.
FAQ
A: Gel-sealed closures use a compound for superior waterproofing and are ideal for permanently sealed environments. Mechanical seals use rubber gaskets for easier re-entry and are perfect for locations requiring frequent maintenance. We provide both types.
A: Our standard dome closures range from 2 to 12 ports and can accommodate from 12 to 144+ splices, depending on the model and splice tray configuration. We offer scalable solutions for various capacity needs.
A: Yes, absolutely. Our splice trays and closures are designed to be fiber-type agnostic. They can securely house and protect splices for both single-mode and multimode fibers, as well as various cable diameters.
