The Horizontal Fiber Optic Closure is a high-performance sealed protective device specially designed for outdoor environments. It achieves dust-proof, water-proof and full environmental factor isolation through IP68-level protection, ensuring the long-term stable operation of optical fiber fusion joints in extreme climates and complex terrains. Made of high-quality UV-resistant polycarbonate (PC) material, it features excellent impact resistance, corrosion resistance and wide temperature range adaptability (-40 °C to +85°C), effectively resisting ultraviolet aging and chemical erosion
Straight-through layout: Innovative three-in and three-out port design, supporting flexible wiring route planning, perfectly adapted to the diverse installation scenarios of FTTH (Fiber to the Home) networks. It has passed the RoHS 2.0 international environmental protection certification. The materials throughout the entire life cycle comply with the EU's hazardous substance limit standards, practicing the concept of green network construction

Key Features & Benefits
Convenient installation and maintenance
Adopting a tool-free and rapid installation design, it simplifies the on-site construction process and significantly shortens the deployment time. Supports tool-free maintenance operations, allowing for quick fiber optic management adjustments without the need for professional tools, significantly reducing the difficulty and time cost of operation and maintenance.
Full environmental protection capability
It has passed the IP68-level protection certification, providing complete dust-proof and deep water-proof protection (able to be immersed in water for a long time), ensuring stable performance in extreme weather conditions, high humidity environments and harsh outdoor scenarios, and providing a reliable protective barrier for optical fiber fusion joints.
Ultra-high density optical fiber management
The innovative compact structure design supports up to 576 cores of optical fiber splicing in a single box, breaking through the capacity limitations of traditional joint boxes and enabling high-density optical fiber deployment in limited Spaces. It is particularly suitable for optical fiber resource-intensive scenarios such as data centers, urban access networks, and large-scale FTTH projects.
Industry application scenarios and solutions
The core connection component for multi-scenario adaptation
The optical channel direct connection type optical fiber joint box is a multi-functional connection hub for modern telecommunication networks, specially designed for FTTH (Fiber to the Home), FTTB (Fiber to the Building) and FTTX (Fiber to X) networks. As a key interface between the distribution network and user terminals, it provides reliable support for optical fiber access in all scenarios.
