Outdoor fiber optic termination boxes generally have a larger capacity and are made of better materials than indoor boxes, offering greater durability and resistance to UV radiation, and can withstand various harsh outdoor weather conditions. They are commonly installed in locations such as walls, utility poles, aerial cables, manholes, handholes, and conduits.
Yingda can provide various types of fiber optic splice box outdoor, end users can choose according to their project requirements & budget, and actual usage scenarios, focusing on environmental conditions, capacity requirements, and functional characteristics.
Environmental Adaptability
Extreme Climates: For outdoor environments (such as deserts and coastal areas), stainless steel or SMC materials (corrosion-resistant and UV-resistant) should be selected, and the operating temperature range must cover -40℃ to +60℃.
Mechanical Protection: For direct burial or overhead environments, armored structures (such as steel tape/steel wire armor) are preferred, with a compressive strength of ≥2000N and rodent-proof design.
Capacity and Scalability
Small-scale scenarios (homes/surveillance): 4-12 core outdoor fiber optic termination boxes, such as 6-core plastic terminal boxes (lightweight and low-cost).
Medium to large-scale scenarios (campuses/data centers): Metal boxes with 24 cores or more, supporting both fusion splicing and mechanical splicing, with 20% redundant ports reserved.
Functional Features
Sealing: Fiber optic splice box outdoor mostly meet ingress protection IP65 or higher protection rating, anti-theft door lock design, waterproof sealing strip must pass a 2000N tensile test.
Cable Management: Built-in curvature radius control (>30mm), flip-open structure for easy maintenance.
Installation Methods
Wall-mounted/Pole-mounted: Suitable for corridors or utility poles, enclosure depth ≤200mm.
Direct burial/Aerial: Requires matching armored fiber optic cable (such as GYTA53) or ADSS fiber optic cable (for electromagnetic interference resistance).
Conclusion
Based on practical scenarios, Yingda recommend a few outdoor fiber optic termination boxes for your reference as below:
| Scenarios: | Recommended types: | Key parameters: |
| Home FTTH (Fiber to the Home) | Plastic wall-mounted box (6-12 cores) | IP65, SC connector |
| Industrial areas | SMC, Stainless steel armored box (24 cores+) | IP68, -40℃~+80℃ operating temperature range |
| Data center interconnection | Rack-mounted ODF (96 cores+) | LC high-density, hot-swappable |
