Features
Fast Installation and Easy Re-entry
The snap-fit sealing mechanism allows tool-less opening and closing, significantly reducing installation time compared to heat-shrink or adhesive systems.
Mechanical seal maintains integrity through multiple re-entry cycles
Ideal for networks requiring frequent maintenance or phased deployment
Clear internal layout and logical cable routing paths minimize confusion
Optional air valve enables flash testing for seal verification
High-Density Fiber Management with Stackable Trays
The internal structure accommodates up to four stackable splice trays, each with 36-fiber capacity, arranged in a flip-up configuration that allows easy access to individual trays without disturbing other layers.
Integrated fiber routing guides maintain minimum bend radius requirements (typically 30mm)
Color-coded fiber management zones and clear labeling areas
Excess fiber storage areas provide secure loops for slack management
Flip-up tray configuration allows easy access to individual trays
Flexible Cable Port Design
The closure features one oval port designed for through-cable applications and four round ports for branch connections, accommodating cable outer diameters from Φ8mm to Φ18mm.
- Supports various cable types including loose tube, SZ stranded, and central tube designs
- Ports incorporate rubber grommets and mechanical compression seals
- Seals adapt to different cable diameters while maintaining IP68 integrity
- 2-in-4-out arrangement enables efficient network topology designs
IP68-Rated Protection for Harsh Outdoor Environments
The closure housing is injection-molded from PP+GF composite material, providing exceptional mechanical strength while maintaining light weight for easy handling during installation.
- Multi-layer gaskets with precision compression create a watertight and dustproof barrier
- Withstands submersion up to 1.5 meters
- UV-stabilized materials resist degradation from prolonged sunlight exposure
- Chemical-resistant formulations protect against acids, alkalis, and salt spray

FAQ
Q: Frequently Asked Questions
A: Can the fiber count or tray configuration be customized?
Yes, absolutely. While our standard 144F model comes with four 36-fiber trays, we can customize splice capacity from 24 fibers up to 288 fibers or higher. Tray configurations can be modified for different fiber counts per tray (12F, 24F, 36F, or 48F), and we can adjust the internal structure to accommodate ribbon fiber cassettes or specialized splitter modules. Contact our engineering team with your requirements for detailed design proposals.
Q: What cable diameters and types are supported?
A: The standard configuration supports cable outer diameters from Φ8mm to Φ18mm, compatible with loose tube, SZ stranded, and central tube cable constructions. For custom applications, we can modify port sizes to accommodate cables from Φ5mm to Φ25mm. The mechanical sealing system works with both armored and non-armored cables. If your project requires unique cable types such as ADSS, micro-duct cables, or hybrid fiber/copper cables, we can adapt the port design accordingly.
Q: Does the closure support repeated opening without losing IP68 performance?
A: Yes, the mechanical sealing system is specifically engineered for multiple re-entry cycles while maintaining IP68 integrity. Unlike heat-shrink closures that require consumable sleeves for each opening, our mechanical seal uses precision-molded gaskets and compression rings that remain effective through dozens of open/close cycles. This makes it ideal for networks that require frequent maintenance, phased fiber activation, or troubleshooting access. We recommend periodic inspection of gaskets after 20+ re-entries, and replacement gaskets are available as service parts.
Q: Can you supply mounting kits and accessories for our specific installation scenario?
A: Yes, we offer both standard and custom mounting solutions. Standard accessories include pole mounting straps for 60–200mm diameter poles, wall mounting brackets with adjustable angles, aerial suspension kits for messenger wire installation, and underground vault positioning hardware. For unique scenarios, we can engineer custom mounting systems-for example, specialized brackets for non-circular poles, corrosion-resistant stainless steel hardware for marine environments, or vibration-dampening mounts for installations near railway tracks or highways.
Q: What is the typical lead time for ODM/OEM projects?
A: Lead times vary based on customization complexity. For simple modifications such as logo printing or cable port adjustments using existing tooling, samples can be ready in 7–10 business days with production runs of 4–6 weeks. More complex projects requiring new mechanical designs, custom tooling, or material certifications typically require 3–4 weeks for engineering and samples, followed by 6–8 weeks for production tooling and initial manufacturing. We work closely with customers to establish realistic timelines that align with project deployment schedules, and can accommodate expedited programs when needed.
