Outdoor fiber optic termination boxes generally have a larger capacity and are made of premium materials than indoor ones, offering excellent durability and environmental resistance against UV radiation. These boxes are engineered with a high protection level to withstand harsh outdoor network environments. They are commonly installed in locations such as walls, utility poles, aerial cables, manholes, handholes, and conduits. As a professional outdoor fiber optic termination box manufacturer, Yingda provides various types of fiber optic splice box outdoor to fit your project budgets and different application scenarios.
Environmental Adaptability & Durability Factors
Extreme Climates: Choosing materials with strong environmental resistance ensures the fiber termination box durability spans over 20 years in outdoor fields. 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), which serve as an ideal fiber optic termination box outdoor solution for residential FTTH.
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 & Protection Levels
Sealing: To build a secure outdoor network, a fiber optic splice box outdoor must meet an ingress protection level 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 for Outdoor Networks
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).
