The Fiber Optic Splice Closure (FOSC), also known as a fiber optic splicing closure, is designed to protect optical fiber splices from moisture, dust, mechanical impact, and environmental conditions during outdoor FTTX network deployment.
Fiber splice closures are widely used in aerial, underground, duct, wall-mounted, and pole-mounted installations, providing reliable protection for straight-through, branching, and mid-span fiber cable connections.
According to installation requirements, fiber splice closures are generally divided into two types:
Fiber optic splice closure, FOSC-2D.5 (64)
The Jera FOSC-2D.5 Dome Fiber Optic Splice Closure is designed to protect fiber optic cable joints in both straight-through and branch splicing applications. It provides reliable fiber management while maintaining excellent sealing performance under harsh outdoor environments.
This enclosure is suitable for:
-
Aerial fiber optic cable installation
-
Underground deployment
-
Pole-mounted installation
-
Wall-mounted installation
-
Duct installation
-
FTTH and FTTX access networks
Manufactured from high-quality UV-resistant engineering thermoplastic, the closure provides long-term protection against UV radiation, corrosion, moisture, and dust while ensuring stable network performance.

Fiber Management Design
The FOSC-2D splice closure is designed for efficient fiber organization and long-term protection.
Outdoor fiber optic cables enter the enclosure through sealed cable ports, where fibers are spliced and neatly arranged inside removable splice trays. Each tray securely holds splice protection sleeves while minimizing the risk of accidental fiber damage during installation or maintenance.
The splice trays also support the installation of:
-
One 1:8 blockless PLC splitter
-
Two 1:4 blockless PLC splitters
This integrated splitter design simplifies fiber management and maximizes the available storage space inside the closure.
