Product Details

Our Fiber Dome Closure series is celebrated for its unmatched high-capacity and reliability.

It safeguards fiber optic connections across a spectrum of environments to meet the  requirements of contemporary fiber optic networks.

Robust Features for High-Capacity Networking

  • Standards Compliance: Each dome closure adheres strictly to the most recent national standards, ensuring high-quality performance in all operational aspects.
  • Durable Materials: Constructed using advanced high-strength engineering plastics, our closures are lightweight yet robust. It offers superior mechanical strength, anti-aging properties, exceptional corrosion and lightning resistance, and a prolonged lifespan.
  • Multiple Cable Ports: Equipped with 16 circular and 1 oval cable ports, totaling 17 entry points. The oval port facilitates convenient cable loop-through, enhancing the system’s flexibility.
  • Flexible Splice Management: The innovative stacked splice tray design allows for adaptable fiber core management. Coupled with an independent insulation grounding device, the closures ensure safe and effortless handling. This design promotes easy fiber configuration, expansion, and secure cable grounding.
  • PLC Splitter Integration: Our Type 3 splice tray features dedicated slots specifically for 1:8 or 1:16 PLC splitters. Seamlessly accommodating these devices to support high-capacity splitting requirements.
  • Versatile Installation Options: Whether the need is for overhead, pole, wall, or underground installation, our fiber dome closures offer excellent sealing performance, adaptable to various installation scenarios without compromising protection.

Advanced Technical Specifications

  • Optimal Fiber Bend Radius: Maintains a radius of curvature greater than 40mm, crucial for minimizing signal loss and ensuring the integrity of fiber connections.
  • Minimal Optical Loss: Achieves an optical tray additional loss of ≤0.01dB, critical for maintaining signal strength in high-capacity networks.
  • Broad Temperature Adaptability: With a temperature range of -20℃ to +60℃, dome closures withstand extreme environmental conditions.
  • Exceptional Pressure and Shock Resistance: Rated to withstand lateral pressure of ≥2000N/10cm and shock resistance of ≥20N.m, our dome closures endure physical stresses.
  • Superior Protection Level: Boasting an IP68 rating, our closures are completely dust-tight and protected against long-term immersion in water, ensuring the highest level of ingress protection.


Our Fiber Dome Closure solutions can address the needs of FTTA junction boxes and other high-capacity fiber optic applications.

Trust in our closures for state-of-the-art protection and performance that keep pace with the growing demands of advanced fiber optic networks.
