FOSCIQ4 Inline Type Fiber Optic Splice Closure (FOSC)

Integrating FirstFiber's FOSCIQ4 inline splice closure into our high-density optical backbone expansion solved our cable management requirements. The reusable mechanical sealing structure with thermoplastic rubber grommets allows field crews to reopen and seal the housing cleanly without heat shrink torches. Featuring 4 uniform cable ports accommodating diameters up to 20 mm, it offers ample entry capacity for main trunk cables. The unit holds up to 6 dual-layer splice trays, supporting up to 288 bunchy fibers (48 fibers per dual-layer tray) or an impressive 576 ribbon fibers. Constructed from durable Polycarbonate (PC) and operating across -40°C to +65°C, it provides complete weather-resistant protection in aerial, pipeline, and manhole deployments.

At a reference price starting at just $15 USD, FirstFiber's FOSCIQ4 delivers remarkable enterprise-grade value for high-density optical networks. Measuring 605 (L) × 215 (W) × 120 (H) mm with a net weight between 2.6 kg and 4.6 kg, the slim chassis provides generous tray capacity while remaining easy to position during overhead aerial hanger or wall installations. The product arrives as a complete turnkey kit supplied with standard accessories, including M8, M6, and M10 wrenches, 4 hose clamps, 4 steadies, 8 cable sealing rings, 2 aerial hanging hooks, sealing tape, insulation tape, grounding wire, abrasive cloth, and protective sleeves. Supporting up to 576 ribbon fibers, it is an exceptionally scalable, budget-friendly inline closure.

We standardized on the FOSCIQ4 for direct-buried, pipeline, and manhole fiber splicing contracts due to its rigid Polycarbonate outer body. Secured by heavy-duty bolts and an internal sealing grommet, the chassis withstands soil compression and water immersion without leaking. We opted to equip our units with the optional pressure testing valve and desiccant bag to perform air tightness checks prior to trench backfilling. The 4 cable plugs maintain airtight seals on unused ports, while the central foundation plate firmly anchors cable strength members. It is a thoroughly dependable, reusable inline splice closure for long-term outdoor cable management.
