Product Overview
The Qianhong Fiber Optic Splice Closure (FOSC) features a classic dome-shaped structure designed to provide reliable protection and organized fiber splicing for outdoor optical networks. It combines fiber connection, splicing and cable protection in a single enclosure.
The closure supports several installation configurations, including aerial cables, pole-mounted networks, pipeline applications and direct-buried installations. Its flexible structure makes it suitable for different outdoor deployment environments.
Built with strong mechanical properties, effective sealing and resistance to corrosion and changing weather conditions, the enclosure is designed for long-term outdoor use. Its reusable mechanical structure also allows maintenance and re-entry when network modifications or repairs are required.
With a practical internal layout, the closure is designed to simplify installation and improve deployment efficiency. The Qianhong FOSC product range focuses on four important requirements for fiber network construction: reliability, easy installation, flexibility and deployment efficiency.
Key Features of the Dome Fiber Optic Splice Closure
1. Dome-Shaped Protective Structure
The classic dome configuration provides a compact enclosure for organizing and protecting fiber splicing components. It is suitable for a range of outdoor optical cable deployment environments.
2. Strong Mechanical Performance
The enclosure is manufactured from PP+GF material, providing a robust structure suitable for outdoor network installations.
The housing is designed to withstand common mechanical stresses encountered during transportation, installation and long-term deployment.
3. Reliable Sealing Performance
The closure uses a heat-shrink sealing method to help protect internal fiber connections against external environmental conditions.
With an IP68 protection grade, the enclosure is designed for applications requiring a high level of protection against dust and water ingress.
4. Reusable and Maintainable
The mechanical structure allows the closure to be reopened when maintenance, fiber re-splicing or network expansion is required.
This re-entry capability can help reduce unnecessary replacement of the complete enclosure during future network maintenance.
5. Multiple Installation Configurations
The FOSC can be deployed in different network environments, including:
This flexibility allows the same product platform to serve different fiber network layouts.

Fiber Capacity and Cable Entry Design
The GJS03-M1AX-SC-24 model is designed for fiber network applications with a maximum capacity of 48 cores.
It provides 1+4 cable entry ports, allowing different cable routing configurations according to the network layout. The closure accommodates oval cables measuring 62 × 37 mm and round cables with a diameter of 24.5 mm.
The maximum splice tray capacity is 24, providing space for organized fiber splicing and cable management within the enclosure.
IP68 Protection for Outdoor Deployment
Outdoor fiber optic equipment needs to remain protected from environmental exposure throughout its service life.
The Qianhong dome splice closure is rated IP68, providing a high level of enclosure protection against dust and water ingress when correctly installed and sealed.
Combined with the heat-shrink sealing structure, the enclosure is suitable for outdoor applications where moisture, dust and changing weather conditions need to be considered.
Flexible Fiber Network Applications
The dome-type structure allows the Qianhong Fiber Optic Splice Closure to be used across different deployment scenarios.
Wall-Mounted Networks
The closure can be installed on walls where optical cable splicing and protection are required in fixed outdoor or infrastructure installations.
Pole-Mounted Applications
For overhead fiber networks, the closure can be adapted to pole-mounted deployment, providing a protected location for fiber splicing.
Aerial Fiber Networks
Its outdoor-oriented construction makes it suitable for aerial cable applications where the enclosure must remain exposed to environmental conditions.
Pipeline and Direct-Buried Installation
The product can also be used in pipeline and direct-buried network configurations, offering additional deployment flexibility for underground optical cable infrastructure.
Designed for Easier Fiber Network Maintenance
Fiber optic networks may require future expansion, repair or reconfiguration after initial installation. For this reason, maintainability is an important factor when selecting a splice closure.
The reusable mechanical structure of the Qianhong FOSC allows technicians to access the internal components when required. This can simplify maintenance operations and provide greater flexibility when network conditions change.
The organized internal structure also helps make fiber splicing and cable management more straightforward during installation and servicing.
Customization Options
Different fiber network projects may require different cable, adapter or configuration specifications.
The Qianhong splice closure supports customization according to customer requirements. Depending on the project, relevant configuration options can be discussed for applicable cable types, adapters and other product requirements.
This makes the Dome Type Fiber Optic Splice Closure suitable for both standard network deployments and projects with specific installation conditions.
A Reliable Solution for Outdoor Fiber Connections
The Qianhong Fiber Optic Splice Closure combines a dome-shaped enclosure, PP+GF construction, heat-shrink sealing and IP68 protection in a compact fiber management solution.
With support for up to 48 fiber cores, multiple cable entry ports and wall, pole, aerial, pipeline and direct-buried applications, the GJS03-M1AX-SC-24 model provides flexibility for different outdoor optical network configurations.
For fiber optic network contractors, distributors and infrastructure developers, its combination of protection, maintainability, installation flexibility and organized fiber splicing makes it a practical choice for outdoor fiber connection and distribution projects.
