FOSCIK2 Inline Type Fiber Optic Splice Closure (FOSC)

Integrating FirstFiber's FOSCIC8 inline splice closure across our optical backbone simplified multi-cable routing and drop branching. Featuring 8 entry ports split into two sizes—4 ports for cables up to 16 mm and 4 ports for cables up to 20 mm—it gives field technicians excellent layout flexibility. The reusable mechanical sealing structure with thermoplastic rubber grommets forms a watertight seal without requiring heat shrink torches. Constructed from high-impact Polycarbonate (PC) and engineered to function across temperatures from -40°C to +65°C, it provides weather-resistant protection in aerial, pipeline, wall-mount, and manhole installations. Internally, its 4 splice trays support up to 96 bunchy fibers (24 per dual-layer tray) or 288 ribbon fibers.

At a reference price starting at just $17 USD, FirstFiber's FOSCIC8 delivers exceptional commercial value for B2B fiber infrastructure builds. Measuring 450 (L) × 220 (W) × 110 (H) mm with a net weight between 2.8 kg and 3.3 kg, the enclosure is easy for field crews to maneuver during aerial hanger and wall deployments. The product arrives as a complete turnkey kit furnished with standard accessories, including M8, M6, and M10 wrenches, 2 aerial hanging hooks, 2 pairs of insertion plates, 8 port plugs, sealing tape, insulation tape, nylon ties, a grounding wire, abrasive cloth, and fiber protective sleeves. Supporting up to 288 ribbon fibers with orderable core configurations ranging from 24 to 96 Cores, it is an extremely cost-effective choice for expanding municipal FTTx lines.

We standardized on the FOSCIC8 for direct-buried, pipeline, and manhole fiber splicing contracts due to its rigid Polycarbonate outer body. Joined by heavy-duty bolts and insertion plates, the housing withstands heavy soil compression and environmental stress without leaking. We opted to equip our units with the optional pressure testing valve and desiccant bag to perform air pressure integrity checks prior to trench backfilling. The central foundation plate firmly anchors cable strength members and buffer tubes, while the 8 port plugs maintain airtight seals on unused cable entries. It is a thoroughly dependable, reusable inline splice closure for long-term outdoor cable management.
