Buy Quality Fiber Optic Splice Closures from Leading China Manufacturer

Fiber Optic Splice Closure (FOSC) is an essential protective housing used for the continuity, branching, and management of optical cables. As a premier solution from the Ningbo Yuanyi factory, these closures are engineered to provide a rugged, hermetically sealed environment that shields delicate fiber fusion splices from water, dust, and mechanical stress, ensuring long-term signal stability in the most demanding outdoor conditions.

1. Key Designs & Configurations

Drawing on years of manufacturing expertise, Ningbo Yuanyi offers two primary configurations to suit various deployment needs:

Dome (Vertical) Type: Featuring a cylindrical shape with all cable ports located at the base. This design is highly preferred for underground, manhole, or pole-mounting applications due to its superior sealing and vertical space efficiency.

Horizontal (In-line) Type: Characterized by a flat, rectangular profile with cable entries at both ends. It is ideal for aerial installations or shallow duct environments, offering easy access for maintenance and expansion.

2. Core Technical Features

High-Strength Engineering: Every closure is molded from premium, UV-resistant, and anti-corrosive plastics (such as PP or ABS). This ensures the device can withstand extreme temperatures, high pressure, and physical impact, reflecting Ningbo Yuanyi’s commitment to industrial-grade quality.

Advanced Sealing Systems: Available in both Mechanical Seal and Heat-Shrink Seal versions. The mechanical seal design allows for repeated reopening and re-entry without the need for specialized tools or replacement kits, significantly reducing maintenance costs.

Precision Fiber Management: The interior features multi-layer, flip-style splice trays. These trays ensure a minimum bending radius of 30mm for all stored fibers, preventing macro-bending losses and organizing fibers for easy identification.

Scalable Capacity: Depending on the model, these closures can support fiber counts ranging from 12 to 288+ cores, making them suitable for both local access networks and long-haul backbone lines.
