Fiber Joint Closure Splice Tray Configuration

This fiber splice closure is equipped with 6 splice trays, each supporting 12/24/48 fiber splices, allowing a total capacity of 288 fiber cores. The internal structure provides sufficient space for fiber winding and storage, supporting both straight-through and branching cable applications commonly required in inline fiber joint closure deployments.

Key Features

Supports up to 288 fiber splices
Inline / horizontal fiber joint closure design
IP68-rated mechanical sealing for outdoor and underground use
Spacious internal layout for fiber winding and storage
Sealing structure maintains performance after re-entry and reuse
Designed for straight-through and branch cable configurations
Improves installation efficiency and reduces field operation time

YFY’s production capacity for fiber joint closure ranges from 25,000 to 30,000 units per month, supported by dedicated molding, assembly, and inspection lines. In-house production management ensures stable output, consistent quality, and reliable lead times for both standard supply and OEM/ODM manufacturing programs.

Each fiber joint closure undergoes structured inspection and validation to ensure long-term field performance.

Testing includes:

Salt spray corrosion testing
UV resistance testing
Free-fall and impact testing
Torsion and mechanical strength testing

This inspection process ensures the durability, sealing reliability, and mechanical stability required for telecom infrastructure deployment.

An inline fiber joint closure is typically used in straight-through cable routes where fibers continue along the same direction, making it suitable for linear network layouts.

A dome-type fiber joint closure is more commonly applied at branching points where multiple cables are distributed from a central location.

Selecting the appropriate fiber joint closure depends on network topology, cable routing, and installation environment.

Yes. This fiber joint closure is designed with a mechanical sealing structure and IP68 protection, making it suitable for underground and direct burial installations when installed according to recommended practices.

As a fiber splice closure, it provides reliable protection against water ingress, moisture, and environmental stress commonly encountered in underground deployments.

Yes. This inline fiber joint closure is designed to support both bunchy and ribbon fibers, depending on the splice tray configuration used.

During project evaluation, a fiber joint closure manufacturer can recommend suitable splice trays and internal layouts to ensure proper fiber management and installation efficiency for different fiber types.
