FOSCID6 Inline Type Fiber Optic Splice Closure (FOSC)

Integrating FirstFiber's FOSCID6 inline splice closure across our network backbone resolved several multi-cable routing challenges. Featuring 6 entry ports—2 ports up to 13 mm, 2 ports up to 16 mm, and 2 ports up to 20 mm—it gives technicians excellent flexibility when branching main trunk cables into smaller distribution feeds. The reusable mechanical sealing structure with thermoplastic rubber grommets ensures an airtight seal without requiring heat shrink torches. Constructed from durable Polycarbonate (PC) and operating across severe temperatures from -40°C to +65°C, it maintains watertight protection in aerial, wall-mount, direct-buried, and manhole installations. Internally, its 4 splice trays accommodate up to 96 bunchy fibers (24 per dual-layer tray) or 144 ribbon fibers.

At a reference baseline price starting at just $18 USD, FirstFiber's FOSCID6 offers exceptional commercial value for B2B fiber optic deployments. Measuring 396 (L) × 200 (W) × 126 (H) mm with a net weight ranging from 2.5 kg to 2.7 kg, the inline chassis is compact and lightweight, making overhead aerial hanger or wall installations straightforward for field crews. The kit arrives completely furnished with standard hardware, including 2 aerial hanging hooks, 2 pairs of insertion plates, M8 and M10 wrenches, sealing tape, insulation tape, nylon ties, a grounding wire, abrasive cloth, and fiber protective sleeves. Supporting up to 144 ribbon fibers with orderable core o

We standardized on the FOSCID6 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 chassis withstands 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 secures cable strength members, while the 6 port plugs maintain airtight seals on unused cable entries. It is a thoroughly dependable, reusable inline splice closure for long-term outdoor cable management.
