Horizontal Optical Cable Splice Closure

Product Overview

The Horizontal Fiber Optic Cable Closure, also known as a fiber optic splice closure, is a dedicated splice protection device for outdoor fiber optic communication lines, designed specifically for straight-through and branch splicing. The box body is molded as a single piece from high-strength modified polymer plastic, offering flame-retardant, impact-resistant, tension/torsion-resistant, and UV-aging-resistant properties. Combined with a non-vulcanized self-adhesive rubber mechanical sealing structure, it achieves an IP68 protection rating, blocking out rainwater, temperature fluctuations, and microbial erosion to fully protect fiber splice points. Internally, an integrated cable fixing plate and steel-core reinforcement fixing structure saves internal space and increases fiber storage capacity. It is equipped with 4 cable ports (2 inlets and 2 outlets), compatible with Φ10 to 18mm cables, and can hold up to 3 trays of 24-fiber splice trays for a maximum capacity of 72 fibers. It supports the two mainstream installation methods of aerial and duct deployment, making it suitable for various outdoor cable deployment projects.

Key Advantages

IP68 High-Grade Mechanical Sealing for All-Weather Waterproofing and Moisture Resistance

The unit uses mechanical compression sealing combined with non-vulcanized self-adhesive rubber, with cable ports sealed via nut compression, achieving an IP68 protection rating. It can withstand long-term exposure to rain immersion, underground moisture, and alternating high and low temperatures in harsh outdoor environments, slowing component aging.

Integrated Reinforcement Core Fixing for Higher Internal Space Utilization

The cable fixing plate and steel-core reinforcement fixing device are integrated into a single design, reducing the space occupied by redundant internal components and reserving a larger fiber coiling area. This keeps slack fiber storage neat and organized, avoids bending loss, and results in tidier cable routing.

Wide-Compatibility Cable Ports with Flexible Sealing Assembly/Disassembly

Features 4 cable channels (2 inlets and 2 outlets), compatible with the full Φ10 to 18mm cable range. The compression-nut sealing structure offers strong adaptability—adding or removing cables does not require replacing the entire sealing accessory set—resulting in broad installation compatibility.

Complete Accessories for Multiple Scenarios with Flexible Installation Methods

Comes standard with wall-mounting hardware, with optional aerial mounting hardware and an inflation valve available. It supports both aerial and duct deployment scenarios, with complete accessories to meet the installation needs of different line construction projects.
