Introduction to Fiber Optic Splice Closure

Fiber optic splicing is important for fiber connections. Fiber Optic Splice Closure is a fiber management product typically used with outdoor fiber optical cables. It provides space and protection for the fiber optic cable splicing and joint. Fiber splice closure is used for aerial, strand-mount FTTH “tap” locations where drop cables are spliced to distribution cables.

What is a Fiber Optic Splice Closure?

fiber optic splice closureIn fact, except underground application, fiber optic splice closure is also used for aerial, strand-mount FTTH “tap” locations where drop cables are spliced to distribution cables. It is usually used with outdoor fiber optic cables which provides space for the outdoor fiber optic cables to be spliced together. The fiber optic splice closures and the fiber trays inside will protect the spliced fiber and the joint parts of the outdoor fiber cables.

Fiber optic splice enclosures are used to protect stripped fiber optic cable and fiber optic splices from the environment, and they are available for indoor as well as outdoor mounting. Outdoor fiber optic enclosures are usually weatherproof with watertight seals. In a typical wall-mounted splice enclosure, fiber optic cable is supported by cable ties, and the cable strength member is securely fastened to the enclosure’s support. Metallic strength members must be grounded securely. The cable jacket(sheath) stops at the splice enclosure’s cable ties. Optical fiber tubes, individual tight-buffered fibers, or pigtails are supported by the tube brackets and continue to the splicing trays.

Key Features of Fiber Optic Splice Closures

Fiber splice closures are made from special industrial grade, high tension plastic with a reliable moisture barrier. They are also optimized to resist aging of the material due to factors in the natural environment such as ultraviolet light.

  • The box adds aging-resistant in imported high tensile construction plastic out-faster is made up of stainless steel
  •  Overlap structure in splicing tray is easy to install
  •  Suitable for ordinary fiber and ribbon fiber
  •  Perfect leak proof
  •  Perfect and reliable sealing operations
  •  Fiber-bending radium guaranteed more than 40mm
  •  Full accessories for convenient operations
  •  Fiber optic splice closure can be used repeatedly
  •  For aerial, and direct buried applications

Generally, the fiber optic splice closures are horizontal types and dome type (also called vertical type). Horizontal types are used more often than vertical type (dome type) closures.

Horizontal Types

Horizontal types splice closure looks like a flat or cylindrical box which provides space and protection for fiber optic cable splicing and joint. They can be mounted aerial, buried, or for underground applications. Most horizontal fiber optic splice closure can fit hundreds of fiber connection. They are designed to be waterproof and dustproof. They can be used in temperature ranging from -40°C to 85°C, can accommodate 70 to 106 kpa pressure and the case is usually made of high tensile construction plastic.

Vertical Types

Vertical type of fiber optic splice closure looks like a dome. This is why they are also called dome type. They meed the same specification as the horizontal types. They are usually designed for buried applications.

Conclusion

Fiber-Mart supplies two types of fiber splice closures which are the horizontal (inline) type and the vertical (dome) type. Both are made of excellent engineering plastics to be waterproof and dustproof. And with various ports types, they can fit different fiber optic core numbers. Fiber splice tray, fiber distribution box, and fiber optic enclosure are also offered in conjunction with the splice closures, promoting a safe and well-managed environment for fiber optic splices. Custom service is available according to your requirement.
