Common Types of Fibre Optic Splice Closure Used by 5G Companies

5G Technology has indeed brought a huge revolution in the networking industry. Nowadays, optical fibres are the foundation for the for forthcoming 5G networks. It has become an absolute necessity for everyone. Also, to provide lightning-fast internet, optical fibre is considered to be extremely reliable and now it’s almost impossible to live a life without high-speed internet. 5G Providers offers extraordinary speeds, enhanced capacity, and unlimited connectivity which allows customers to have an amazing experience and stay connected with the virtual world 24/7. However, protection of fibre optic cables is done through fibre optic splice closure which is used by Telecom and numerous other 5G Companies.

What is Fibre Optic Splice Closure?

Fibre Optic Splice Closure or Fibre Optic Closure are devices used to protect fibre optic cables from the harsh realities of Mother Nature. These optical fibre cabling can be exposed to unpredictable climates such as heavy rain, blizzard, or even sandstorms. Therefore, telco companies use special protective devices known as Fibre Optic Splice Closure to prevent damage to their precious Fibre Optic Cables due to environmental calamities.

Types of Fibre Optic Splice Closures:

There are mainly two different types of fibre optic splice closures. Each type has its advantages and serves its intended purpose.

Vertical Design

During 5G Installation, the vertical design has a domed shape and is mostly used in underground buried applications. However, it can also be used above the ground but it is best suited for underground applications due to its domed structure. The vertically designed fibre optic closures may have varying capacities and configurations. Moreover, the number of inlet and outlet ports may also vary depending on the number of cables available to fulfil their capacity. Since it is buried, so the technology used by Telecom service providers should be water-resistant, dust-resistant, and should be made with high-quality tensile material so insects cannot damage it and dirt cannot penetrate through it.

Horizontal Design

The horizontal design of fibre optic closure is the most commonly used design by 5G Providers, presumably because of its great flexibility and versatility. This kind of box is usually cylindrical or flat in shape. It can be used in both ways, aerially or buried whichever suits best according to the situation. A horizontal design can have varying capacities depending on the number of cables they can handle. Higher-capacity closures can fit much more. The common numbers for tray capacities usually incorporate 12 and 24 fibres. When a horizontal design is used, Telecom service providers ensure that the horizontal boxes are waterproof, and dust resistant to avoid any future disruptions and damages.


Fibre Optic Closure Benefits:

The protection of fibre optic cables is very vital, even a second’s delay can be extremely disastrous so proper 5G Installation should be done by keeping in mind all the protective measures. Renowned 5G Providers must need to meet strict demands to ensure a high level of protection. There are numerous benefits of fibre optic closure some of which are listed below:

  • Durability: These high-quality fibre optic splice closures last for many years without deteriorating.
  • High Tensile Resistance: They are made up of extremely strong high tensile material which can easily protect enormous amounts of external pressure and keep the inside contents safe.
  • Waterproof: They are water-resistant to prevent moisture from entering the optical fibre cables.


Factors to Consider When Choosing Fibre Optic Closure

When you are choosing the fibre optic closure, you will need to keep in mind some important things such as the environment, configuration, and characteristic of closure. The following factors will assist you in choosing the right fibre optic closure.

Cable Management

A major concern when working with optical fibre cabling in such small quarters to ensure the bending radius stays low. If we ignore this and apply greater stress to the cables so the performance degrades over time.

Placement and Hardware

When placing a fibre optic closure, we may require some additional hardware for it. For instance, when working underground, we need to make sure the technology used is water-resistant and dust-proof. These extra tools and hardware help to resist environmental calamities such as wind, moisture, dirt, insects, etc. All these environmental conditions can severely damage the cables, so we need to make sure we have the proper hardware to prevent the damages.

Cable Compatibility

It is extremely vital to check the compatibility of optical fibre cable beforehand because different designs have a different type of optical fibre cables. For instance, a fibre optic closure which is underground will have a different design as compared to the aerial one.


Nowadays the modern optical fibre splice closures are much more flexible and versatile as compare to the older ones. Easy installation and ease of accessibility have made peoples life much easier.

Entrance Capacity

An entrance capacity in a fibre optic closure is the number of cable ports it has. The number of ports is directly related to the number of cables a closure can handle, which automatically relies on the capacity of the network. The bigger the network, the more cables it requires. Moreover, the size of the ports is reduced by suppliers to reduce the physical size of high-capacity closures.


Before selecting an optical fibre splice closure, you should keep in mind the following points. Mostly, it is quite hard to find an optical fibre spice closure with everything you require but with these points in your mind, you can easily find an optimum optical fibre splice closure which will fulfil all your requirements without any difficulty.
