Fiber Optic Splice Closure Supplier

Fiber Optic Splice Closure (also called Fiber Splice Closure or Fiber Optic Joint Closure) is a protective enclosure designed to house and safeguard fiber optic splices in outdoor or harsh environments. It ensures reliable connections by shielding spliced fibers from moisture, dust, mechanical stress, and temperature fluctuations.                             Types of Fiber Optic Splice Closures:
①Horizontal (Inline) Closure
Cylindrical shape, used for straight-line splicing of two cables.
Common in underground or aerial installations.
②Vertical (Dome) Closure
Dome-shaped, suitable for branching multiple cables (e.g., 1-in/4-out configurations).
Often used in FTTH (Fiber to the Home) networks.
③Heat Shrink Closure
Uses heat-shrink tubing for a tight seal around cables (common in older installations).
④Mechanical Seal Closure
Relies on gaskets and clamps for reusability (modern preference).

Fiber Optic Splice Closure Industry knowledge

Ningbo Goshining Communication Technology Co., Ltd. is a comprehensive enterprise dedicated to designing, producing and selling a full range of fiber optic products, committed to providing high quality and first-class service, meeting all customer needs and providing one-stop solutions. Among our extensive product range, fiber splice closures are a vital component in the industry. This protective box is designed to house and protect fiber splices outdoors or in harsh environments. It protects the fused optical fibers from moisture, dust, mechanical stress and temperature fluctuations, ensuring reliable connections.

Fiber splice closures come in a variety of types, each tailored to a specific application. For example, the horizontal pass-through box is cylindrical in shape and is ideal for linear splicing of two cables, often used in underground or overhead installations. On the other hand, the Vertical (dome) fiber optic splice closure is designed for the branching of multiple cables, such as 1-in/4-out configurations, which are often used in FTTH networks. In addition, heat shrink boxes use heat shrink tubing to form a tight seal around the cable, which is common in older installations. Mechanical seal boxes rely on gaskets and clamps to achieve a reusable seal, making them the modern first choice.

Ningbo Goshining Communication Technology Co., Ltd. not only provides these essential fiber splice closures, but also a wide variety of other products, including fiber optic quick connectors, jumpers, PLC splitters, cables, distribution boxes, and terminal boxes. Our commitment to excellence extends to providing customized services to help customers build their own brands. By combining our expertise in fiber optic technology with innovative solutions, we are committed to improving the reliability and efficiency of global communication networks. Fiber optic splice closures play a key role in this process, ensuring that every connection is safe and durable regardless of environmental conditions.
