Deploying FirstFiber's FOSCYM9 across our aerial FTTx distribution network simplified multi-directional drop cable routing. Designed with 9 entry ports—comprising 1 main 38 mm oval port and 8 separate 13 mm branch ports—it gives field crews unmatched flexibility for branching multiple drop cables from a single junction. The heat-shrinkable sealing structure is purpose-built for uncut cables, making mid-span loop entry fast and completely watertight. Internally, the 6 splice trays handle up to 144 bunchy fibers or 432 ribbon fibers with ease. The included hanging hoops made pole-mounting quick and secure for our installation teams.

At a reference baseline starting at $26 USD, the FOSCYM9 delivers heavy-duty protection that easily matches higher-priced enclosures. Built with a high-impact polycarbonate body and thermoplastic rubber sealing, the unit is rated for severe outdoor conditions from -40°C to +65°C. We installed several units in flooded manholes and direct buried trench runs without a single moisture breach. The compact 470 × 210 mm chassis weighs only 2.6 to 3.4 kg, yet accommodates up to 24 bunchy fiber splices per dual-layer tray. It is a cost-effective, utility-grade closure for high-density cable management.

We standardized on the FOSCYM9 for regional trunk splicing due to its complete accessory package and organized internal layout. Each closure ships with a dedicated fiber holding tray for buffer tube storage, heat-shrink sleeves, a grounding wire, labeling paper, and aluminum-foil protection paper. We also added the optional pressure testing valve to verify airtight seals prior to underground burial. The heat-shrink protective tubes form an airtight seal around all 8 branch lines. It is a reliable, well-engineered dome closure that drastically reduces maintenance headaches across utility network deployments.
