IP68 Waterproof 24-Core Fiber Optic Splice Closure (Joint Box)

The 24-Core Fiber Optic Splice Closure (FOSC) is a heavy-duty, IP68-rated enclosure designed to provide ultimate protection for fiber optic cable joints in outdoor environments. Whether for direct burial, manhole mounting, or aerial hangings, this joint box ensures the integrity of your fiber splices against water, dust, vibration, and extreme temperature fluctuations.

Constructed from high-strength engineering plastics (PP+GF or ABS), the closure features a robust mechanical or heat-shrink sealing system that creates a hermetic seal. It comes pre-loaded with splice trays supporting up to 24 fiber cores (expandable depending on configuration), making it an ideal solution for FTTH distribution, long-haul transmission, and local area network branching. Its user-friendly internal structure allows for easy fiber routing, storage, and re-entry for future maintenance.

IP68 Rated Protection: Fully waterproof and dustproof design, capable of withstanding long-term submersion in water and harsh underground conditions.

Durable Construction: Made of high-impact, UV-resistant Polypropylene (PP) or ABS material, ensuring a lifespan of over 20 years in outdoor settings.

Versatile Mounting: Suitable for multiple installation methods: Aerial (pole mount), Wall-mounting, Direct Buried, and Duct/Pipeline mounting.

Flexible Splice Capacity: Standard configuration supports 24 cores. The modular splice tray design often allows expansion (e.g., up to 48 or 96 fibers) by stacking additional trays.

Reliable Sealing: Features a high-quality silicone rubber gasket sealing system (mechanical) or heat-shrink tubing to ensure airtight performance.

Cable Ports: Equipped with multiple entry/exit ports (e.g., 2 inlet / 2 outlet) to accommodate different cable diameters (Φ8mm - Φ20mm).

Underground / Direct Buried: Protecting fiber joints in trenches or soil where moisture and pressure resistance are critical.

Manhole / Handhole Installation: Safe deployment in sewer or utility tunnels where water immersion is a risk.

Aerial Deployment: Hung on telephone poles or messenger wires for signal distribution in rural or urban areas.

FTTH Drop Cabling: Branching optical fibers from the main feeder cable to distribution cables serving specific neighborhoods.

Telecommunication Networks: Used in CATV, ISP backbone, and telecom base station fiber connections.
