A Fiber Splice Closure is used in fiber optic networking systems. Splicing fibers together in a fiber-optic network is a regular practice during setup, and the spliced fibers must be stored safely. These enclosures are known as fiber optic splice closures that offer a haven for the fiber optic spliced portions. It keeps them safe from harm and breakage.

What is a Fiber Optic Closure?
Fiber optic closure is a device used to provide space and protection to the fiber optic cables spliced together. Fiber closure offers protection to the joint and stores the optical fibers either inside the structures or outside the plant. It is known to have excellent mechanical strength and comprises a robust outside shell. This allows the protection of joints from the hostile environment.
What are the types of fiber optic closure?
Fiber optic closures provide a haven to the joints to support better network connectivity. Protecting the network’s connectivity is crucial, irrespective of the nature, size, or configuration. Several types of fiber optic closures are available on the market today. Customers can select any fiber optic closure to safeguard the networks per their requirements.
Here are the types of fiber optic closures:
It is the most common type of fiber optic closure available in the market. It is primarily used in aerial mounts or buried underground. It is comparatively similar to a flat or cylindrical casting. In order to protect fiber optic splices, one or more than one fiber splice trays are included in a horizontal fiber optic closure. It also offers space for fiber splices. These fiber optic closures are available in both dustproof and waterproof versions.
This type of fiber optic closure has a dome structure which allows the fiber closure to be quickly buried in several applications. It is also known as fiber dome closure. The best thing is you can use these closures above ground also. To meet the demands of the present, vertical fiber closures are available in different types and designs. Due to its structure and application, fiber dome closure requires a high-level sealing and usage of waterproof technologies. For proper working, you may also need to keep the insects and dirt out for vertical fiber optic closures.
A hybrid fiber optic closure is known for its adaptability as it provides the best security to the network irrespective of temperature, weather, or location. You can place it on a wall, aerial, or a cell. Its compact size allows for pedestal installation and other below-grade applications. Another benefit of hybrid fiber optic splice closure is its capacity to accommodate a 48-count feeder cable and 12 flat round or flat drop fibers. It is a groundable device, and you may apply pressure if necessary.
Which are crucial factors in Fiber Optic closure?
You must consider these factors in fiber optic closure:
Cable Compatibility of Fiber Optic Closure
Before selecting a closure type, it is essential to ensure that it is compatible with the cable. The design of a fiber optic coupler will vary according to the application. In addition, the fiber optic antenna coupling will have a different design than those used for underground applications.
The Number of Cable Ports Available
The number of ports available for cable termination in a fiber optic coupler refers to the cable entrance capacity. At the same time, network bandwidth and the number of cables determine the number of cable ports. In short, the small-sized cable ports are used for drop cables as they do not require large-sized closures.
Cable System Termination
Before selecting a joint type, ensure that the cable terminations system guarantees sufficient mechanical strength between the joint and the cable. It will provide long-term stability and functioning. The materials used in fiber optic equipment are vulnerable to contraction and thermal expansions. Here, the material used for making the optical fiber coupling will be able to limit or eliminate the effects of the relative motion between the cable components.
What is splice joint closure?
Splice joint closure permanently connects two fiber optic cables together and have a splice that protects the components. The optical cable connection part is the part that protects the connection between two or more optical cables by the optical cable splice sheath, and meets the requirements of transmission characteristics and mechanical properties.
What are the two types of splice closures?
1. According to the shape and structure of the splice closure, it can be divided into two types: dome type splice closures and in-line type splice closures
2. According to the laying method of optical cable, it is divided into overhead splice closures and direct burial splice closures.
3. According to the optical cable connection method, it can be divided into direct connection type splice closuresand split connection typesplice closures.
4. According to the sealing method, it can be divided into heat shrinkable sealing splice closuresand mechanical sealingsplice closures.
In what applications is a splice closure used?
When the optical cable construction project needs emergency repair, when two optical cables need to be spliced together, the splice closure is needed.
