In urban Fiber to the Home (FTTH) networks, IP68-rated closures safeguard connections from vibrations caused by heavy traffic or construction activities. Similarly, in rural or remote installations, these closures prevent moisture and contaminants from compromising performance. Their rugged design also ensures resistance to impacts and abrasions, making them indispensable for long-term network stability.
The importance of IP68-rated assemblies extends beyond telecommunications. In industrial automation, they enable reliable data transmission between outdoor sensors and control units. In the automotive and marine sectors, they ensure uninterrupted operation in adverse weather conditions. This versatility highlights the critical role of IP68 waterproofing in protecting horizontal splice closures and other essential components.
Design Features of Horizontal Splice Closures
Advanced Sealing Mechanisms
Horizontal splice closures rely on advanced sealing mechanisms to achieve IP68 waterproofing. These mechanisms include heat-shrink and gel-based systems, which provide robust protection against moisture, dust, and extreme temperatures. Mechanical sealing components, such as high-performance gaskets and clamps, enhance durability and allow for reusability. These features ensure that closures maintain their integrity even in harsh outdoor environments.
Engineering tests validate the effectiveness of these sealing technologies. Pressure tests identify potential leaks, while extreme performance tests evaluate resistance to temperature fluctuations and chemical exposure. Quality assurance procedures, such as permeating dye inspections, detect defects that could compromise sealing performance. These rigorous evaluations ensure that horizontal splice closures meet the highest standards of protection.
The FOSC-H10-M exemplifies these advancements with its mechanical sealing structure, which simplifies mid-span applications by enabling splicing without cutting the cable. This design not only enhances efficiency but also ensures long-term reliability in challenging conditions.

Structural integrity plays a critical role in the design of horizontal splice closures. These closures must withstand environmental hazards, including high winds, impacts, and vibrations. Rigorous testing for impact strength, compression, and vibration endurance ensures that closures remain reliable under mechanical stress. Features like reinforced mounts and streamlined profiles further enhance their durability.
A comparative analysis highlights the advantages of different closure designs. Dome-style closures offer cylindrical shapes with excellent environmental protection, making them ideal for pole-mounted installations. Inline closures, with their linear design, provide easy access to spliced fibers and are well-suited for underground installations where space is limited. The FOSC-H10-M combines these strengths with a compact yet robust design, accommodating up to 288 splicing points while maintaining a small footprint.
By integrating these design features, horizontal splice closures ensure the protection and performance of fiber optic networks in diverse applications.
Materials for IP68 Protection in Horizontal Splice Closures
Corrosion-Resistant Plastics and Metals
The materials used in horizontal splice closures are carefully selected to ensure long-term durability and protection against environmental factors. Corrosion-resistant plastics and metals play a pivotal role in achieving IP68 waterproofing. These materials not only enhance the structural integrity of the closure but also protect it from degradation caused by moisture, salt, and industrial pollutants.
