Fiber optic junction boxes without pre-installed jumpers are available for splicing and custom cabling, offering flexibility for FTTH, enterprise, and telecom networks.

Key Features

Fiber optic junction boxes without jumpers are designed to allow direct splicing of incoming and outgoing fibers, rather than relying on pre-terminated pigtails. These boxes typically include:

• Splice trays for organizing and protecting fiber splices.
• Adapter slots for SC, LC, or other connector types, allowing flexible termination.
• Cable management features such as routing guides and storage space for slack fibers.
• Indoor and outdoor suitability, often with IP65-rated enclosures for weather resistance.
• Modular design to accommodate different fiber counts, from small 2-core boxes to larger 48-core or 20-core distribution boxes .

Product Examples

1. GZR Series Rack-Mounted Terminal Box – Offers splicing, distribution, and tray storage without requiring pre-installed jumpers, suitable for network cabinets and optical distribution frames .
2. Extralink ARIA 2-Core Termination Box – Can terminate internal fiber cables with pigtails but also supports splicing-only configurations for wall or stationary installations .
3. 12-Port FTTH Fiber Distribution Box – Supports up to 20-core splicing and 1×8 mini PLC splitter installation, with dual-layer design for separation of splicing and distribution, and does not require pre-terminated jumpers .
4. Custom Fiber Splitter Distribution Boxes – Manufacturers like Hongyou can produce junction boxes according to customer requirements, including versions without jumpers for direct splicing .

Considerations for Procurement

• Fiber Count and Capacity: Choose a box that accommodates your current and future fiber needs.
• Connector Type: Ensure compatibility with SC, LC, or other adapters used in your network.
• Installation Environment: Select indoor or outdoor-rated enclosures based on deployment location.
• Splicing vs Pre-Terminated: Confirm that the box is supplied without jumpers if you plan to perform custom splicing.
• Modularity and Expandability: Modular boxes allow easier upgrades and maintenance.

Where to Source

Fiber optic junction boxes without jumpers can be sourced from industrial suppliers such as DirectIndustry, Yoptic, TopFiberBox, and online marketplaces like Amazon, which offer a range of indoor/outdoor enclosures suitable for FTTH, enterprise, and telecom applications . When ordering, specify that you require jumper-free or splicing-only configurations to ensure the product meets your network design requirements.
