The fiber optic splicing enclosure is an essential part of optical cable networks and plays a vital role in maintaining stability and reliability. Fiber optic splicing boxes will be used extensively in urban construction.

This paper discusses the current problems in Fiber optic fencing enclosure for urban construction. The demand for Fiber optic fencing enclosure equipment is studied in enterprise operations. Finally, the paper proposes Fiber optic splicing to be used in network construction in order to increase the reliability of the network. This enclosure improves the efficiency of network operators by increasing stability and maintainability and reducing their investment.

The network will see an explosion in optical cable networks. Not only are there access optical cables to be used, but also support facilities such as fiber optic splicing enclosures and optical cable junction boxes.

Fiber optic splicing, an indispensable and essential part of optical cable communications line, has a large inventory but also has a great construction demand in construction of urban network.

The investment in fiber optic splicing enclosure is very small, but it has an impact on both the quality of the optical distribution network and the length of the optical cable.

This article will discuss the effects of Fiber optic Splicing Enclosure on Operators and provide application suggestions based upon the experience with optical cable network maintenance and construction.

How many Fiber optic splicing containers are there?

Fiber optic splicing is a device that ensures continuity between optical cables. It also provides sealing, mechanical and optical strength. It is used to branch and straight-through optical cables from various structures, including overhead, pipeline and direct burial. It is an important component of the construction of optical cables lines. It directly affects both the quality and service life of optical cables.

According to the form and structure of fiber optic splicing enclosure, it can be divided into two types: horizontal and cap. There are three options for optical cable laying: overhead, pipeline and direct-buried. The heat-shrinkable sealing type or mechanical sealing type can also be used. Depending on the size of the optical cable out, it can be broken down into one and two out (two in and two outside), one and three out (one in and three out), and even one and eight out (one in and eight out).

What are the main purposes of Fiber optic Splicing Enclosure?

ODN is an important component of PON. Splitter is used to split light in FTTH (FiberToTheHome). A lot of user optical fibres are drawn near the user. These are similar to ODF-type wiring products. There are some differences. For example, there is a large number of user access networks, the structure is complicated, the cost is high, and it is hard to upgrade or maintain. Therefore, wiring products play an increasing role in FTTH. Only quality wiring solutions can ensure that the access network is always available. It is long-term, stable, and reliable.

A Fiber optic splicing enclosure is required for situations where optical cables and fibers are to be connected and scheduled in an ODN network. This includes the nodes from the trunk optical cable and distribution optical cable as well as the drop optical cable’s nodes. It can also be used to terminate and fusion splice the optical fibers. The storage, scheduling, and storage functions. Both cap-type and straight-line splices boxes are available for use in various applications, such as overhead, pipeline and direct burial of facilities external to the facility.

What are the common flaws in Fiber optic splicing?

The actual use of Fiber optic splicing containers can still cause serious problems that affect network quality and user experience. These problems are:

(1) Fiber optic closure deformation and rupture. Some Fiber optic splicing closures may have box bodies that rupture. These are usually caused by deformation, ageing, or damage to the body after a certain period.

(2) Fiber optic splicing is difficult because the closure box does not have enough accuracy. When the optical cable is connected to the box, it is often discovered that the bolts can’t be fastened properly. This causes the sealing performance to not meet the required standards.

(3) Fiber optic closure leaks Some Fiber optic splicing closings can experience network failures due to rainy season or typhoon days. It is discovered that the box body has been infiltrated by water. This can cause the fiber core and performance to be damaged or erode.

This is because some manufacturers made a mistake in order to cut costs or used inferior materials. The index requirements for mechanical strength and corrosion resistance were not met by the Fiber optic splicing close. Or they used low-quality sealing materials. The fiber optic splicing closing’s sealing performance deteriorates too quickly.

The other side is that some construction personnel aren’t qualified, or they don’t follow the required installation procedures during construction. Or, installation errors happen due to complicated Fiber optic closures. Fiber optic closures are more prone to fail. .

What is Fiber optic splicing and enclosure important?

Fiber optic splicing close accounts for less than 1 percent of ODN network construction costs. But, failures directly attributed to the Fiber optical splicing enclosure account 8% of ODN network network failures. As high as 25% of network failures are directly or indirectly caused by poorly protected connection points. The resultant failure can impact business development, decrease user experience, increase maintenance costs, and further highlight the importance of Fiber optic Splicing Enclosures throughout the entire ODN network.

While major operators are now aware of the importance optical cable splice box, it is still a price-oriented approach to central procurement of Fiber optic Splicing Enclosures. This will reduce the cost and complexity of network construction. invest.

But, it is important to consider the fixed investment (CAPEX) and the maintenance cost (OPEX) when operating a network.

CAPAX believes that low-end Fiberoptic closures are usually 1/51/10 as expensive as high-end Fiberoptic closures. A low-end Fiberoptic splicing closure is more cost-effective and has greater operational benefits.

OPEX considers high-end Fiber optical splicing closures to be reliable, low in failure probability, lower replacement costs and have obvious operational advantages.

The cumulative total investment of high end Fiber optic splicing covers is higher than low-end Fiber optical splicing closes when you add together the data from ODN network maintenance and investment in Fiber optic enclosures procurement. After this point, the total investment in low end Fiber optic splicing closings started to exceed that for high-end Fiberoptic closures. Enterprises must ensure that the entire optical network is stable, operable, scalable, and maintainable. Efficiency is the primary goal of their operations.

Fiber optic splicing enclosures in networks have a theoretical useful life of between 10 and 20 years. The high-end Fiber optical splicing closure can be used to reduce the investment required for enterprise operation.

The technological development of the broadband access network has been called x DSL-LANFTTH. The network bandwidth is increasing, the optical cable gets closer to the user, and so is the optical cable’s size.

As urban networks are constructed more efficiently, optical cables used to access them will increase in size.

In the beginning, it was enough to install a small, logarithmic, optical cable within a community. It was also sufficient to install one or more small, logarithmic, optical cables in every building.

Fiber optic splicing will be used as a standard for ODN construction, particularly resident networks. The all-optical city adopts the Fiber optic splicing closing (one in, four out) as its networking mode.

Multiple Fiber optic splicing containers are needed to branch the optical cables many times.

Only one fiber optic splicing closure will be required if one-inmultiple-out is used (eg one-in-8-out) for centralized branching.

A Fiber optic splicing box with one input and multiple outputs can be used to build FTTH-based optical networks. This enclosure has one input and multiple outputs, which allows for more flexibility, meets large-scale deployment requirements, and reduces joint points. Reduce maintenance costs, and lower failure points.

The one-in-8-out mode has a 15% reduction in investment. The reason for this is the large number of optical cables connections that can be saved. This saves the labor cost of optical connection.

Fiber optic splicing boxes that must be built within the community’s red line will need to be installed in wells provided by the developer.

Developers provide the boreholes and the pipeline resources for the community in the red line. The boreholes dug by developers during the construction of the community pipe are typically small because of cost considerations. The holes that can be used for the Fiber optic splicing close can be found among them. There are less wells.

Based on the above analysis and comparison, Fiber optic splicing enclosed with one input, multiple outputs, is a type optical cable network equipment which can meet large-scale deployments of FTTH. It is also an important foundation for realizing an all-optical city.

How to choose Fiber optic Splicing Enclosure?

Select Fiber optic splicing enclosure for reliable quality

Reliability of the network is determined by the quality and safety of the fiber optic splicing box. Users can only get high-quality services from a reliable network that is stable. This will improve user perception and stickiness. To facilitate the construction of all-optical towns, such as in coastal areas or countries with frequent typhoons, rain and humid heat, high-quality Fiber optical splicing enclosures will be required.

High-quality Fiber optic splicing products and reliable brands should be the first choice when building ODN networks. This can reduce enterprises’ operating costs and also improve the brand image of the enterprise and increase users loyalty and stickiness.

Actively Adopt One-In-Multiple-Out Fiber Optic Splicing Enclosure

All-optical cities dominated FTTH have seen a large increase in optical cables. This has also impacted the construction method of optical cable network. Fiber optic splicing enclosures that have one input and multiple outputs can be used to increase flexibility in networking, lower investment, operate and maintain network deployment costs, and better serve different situations.

Enhance the quality and professionalism of construction personnel

Fiber optic splicing system failures can be caused by poor equipment quality and insufficient construction personnel. The result is that the Fiber optic enclosure is not installed according to the instructions. You may have difficulty installing locking parts or the key links. To avoid human-caused network failures, it is essential to select high-quality, easy to install Fiber optic splicing equipment.


As a small but crucial part, the fiber optic splicing container deserves our attention. They should prioritize customer needs, work with their employees to improve quality, and capitalize on the changing times to make the company more successful. To reduce costs and improve efficiency in operating businesses, they must build quality networks with the user experience as their starting point.
