FS 72 Fibers Dome Splice Closure is a versatile and reliable fibre management solution engineered for splicing, branching, and protecting fibre connections in FTTx, backbone, and access networks. The product comes with one pre-installed 12-fibre splice tray and supports up to 6 trays, enabling a maximum splice capacity of 72 fibres. Equipped with 1 uncut port and 4 branch ports with outer diametres ranging from Φ8 to 18mm, ensuring trunk cable continuity while flexibly supporting multiple branch applications. Ideal for aerial, pole, underground, and wall-mounted deployments, it offers broad application adaptability across various installation environments.
Constructed with a rugged PP+GF housing, the closure delivers exceptional resistance to UV radiation, moisture, corrosion, and mechanical impact. The reinforced inner structure enhances durability and maintains fibre integrity under harsh outdoor conditions. A snap-fit sealing mechanism allows quick cover opening without tools, ensuring simple operation and convenient maintenance in scenarios requiring frequent access. Compliant with industry standards, this closure guarantees long-term reliability and superior performance in demanding scenarios.
