Horizontal Fiber Optic Splice Closure

Horizontal fiber optic splice closure is extensively employed in CATV, telecommunications, and fiber optic networks. These horizontal fiber optic splice enclosures are known for their rapid and dependable sealing capabilities, making them ideal for a range of applications, including duct installation, direct burial, and aerial fiber optic cable setups. Crafted from high-strength ABS or PC industrial plastics, our horizontal fiber splice enclosures effectively shield against environmental factors such as heat and oxygen, offering resistance to water, fire, and shocks.

Horizontal Fiber Optic Splice Closure

Horizontal fiber optic splice closure is a passive component that can provide very good protection for the optical fiber splice point. It can be installed overhead, and both pipe installation and underground installation are feasible. Horizontal fiber optic splice closure is also called the dome fiber optic splice closure. The optical fiber input and output are on both sides of the fiber optic splice closure. Horizontal fiber optic splice closure is suitable for backbone network applications. All horizontal fiber optic splice closures have good sealing performance. High-quality PC+ABS material is very durable whether it is overhead, pipeline, or underground.
