Horizontal Fiber Optic Splice Closure

This horizontal (in-line) splice closure securely houses spliced fiber optic cables in a tough, weather-resistant casing. It’s commonly used in direct-buried, aerial, or pipeline installations, offering high mechanical strength and protection against harsh environmental conditions.

1. Structure & Design

• Material: High-strength PC/ABS plastic, UV-resistant and corrosion-resistant

• Shape: Rectangular horizontal (in-line) design

• Splice Capacity: Supports 12 to 288 fibers, depending on the model

• Cable Ports: Typically 4 to 6 round ports, accommodating various cable diameters

• Cable Entry/Exit: In-line cable routing—cables enter and exit from opposite sides

• Sealing Method: Mechanical sealing or heat-shrink sealing for waterproofing

• Internal Structure: Includes stackable splice trays, cable fixing devices, and grounding accessories

• Protection Rating: IP68 for waterproof, dustproof, and high impact resistance

2. Applications

• FTTH (Fiber to the Home) distribution points

• Long-distance trunk fiber cable splicing

• Underground, aerial, and duct installations

• Urban and rural broadband infrastructure

• Optical cable joint boxes for telecom, CATV, and data networks

3. Advantages

• Strong Sealing: Reliable IP68 protection against water, dust, and environmental exposure

• Durable Housing: Withstands temperature changes, pressure, and mechanical stress

• Flexible Splice Management: Stackable splice trays for neat fiber routing and expansion

• Multi-Use: Suitable for various cable types including loose tube, micro cable, and ribbon fiber

• Easy Maintenance: Reusable after re-entry; simple to reopen for inspections or upgrades

• Versatile Installation: Can be buried directly, mounted on poles, or installed in ducts

4. FAQs

Q1: How many cables can be connected in one closure?
A1: Most in-line closures have 4 to 6 cable ports, supporting multiple cable entry/exit points. We offer models supporting from 12 up to 288 fiber cores.

Q2: Can I install this closure underground?
A2: Yes, the IP68-rated sealing makes it suitable for direct-buried or manhole installations.

Q3: Does it support both mechanical and fusion splicing?
A3: Yes, our closures are compatible with both fusion and mechanical splicing methods.

Q4: Is the closure reusable if I need to reopen it later?
A4: Absolutely. The mechanical sealing system allows for easy re-entry and resealing without damage.
