Be sure to clearly state the intended use of the Fiber optic box when you purchase it.

(1) The optical cable structure used. This could be the layered, central tube, or skeleton types.

(2) Environment used: overhead, direct burial or pipeline, etc.

(3) Type of optical fiber: single core, ribbon, etc.

(4) The network structure refers to whether the branch should be on-site or offline. In the future.

In the early days of communication, fiber optic joint boxes were used. Dome closure fiber optic is made using plastic molds. It does not have the same complexity as horizontal fiber optic splice close, and it meets the standards for sealing performance. The demand for dome closure fiber optical is higher than the horizontal fiber optic splice closing. The market has now found that there is a greater demand for horizontal fiber optical splice closure than dome closure fiber optic.

Horizontal fiber optic splice is convenient because it allows for easy installation, maintenance, and expansion. You should always ensure that the product quality is maintained, regardless of whether you are using dome or horizontal fiber optic splice.

Water ingress into the fiber optical joint box is a common phenomenon and is the main reason for the loss of optical cable insulation to the ground. We organized technical personnel and operators with relevant experience to review and summarize the phenomenon. These are the main reasons that the fiber optic joint boxes enter the water and cause damage to the optical cable insulation:

Construction workers who work quickly, minimize construction steps and don’t pay attention to details are the main causes of water ingress.

If the hands are clogged with optical cable grease, or sand, and the sealing strip is dirty, the waterproof module, sealing groove of fiber optic joint enclosure boxes, and outer skin of optical cable are covered with strips. This creates a gap between the surfaces. The sealing tape must remain in close contact with the contaminated surface. The gap will remain even after the fiber optical joint enclosure box screw has been tightened. Water can penetrate the fiber optic joints enclosure box from places that are not visible to the human eye.

It is important to use a clamp or cut a hole in glue-wrapped areas. The clamp or hole should not be too big. If it is too small it will make it difficult for the sealant to adhere to the optical cable. Water seepage can occur when the sealant is squeezed, deformed and moved around.

For different fiber optic joint boxes, the operation points for sealing the box are the same. Follow the manufacturer’s instructions to seal the fiber optic joint enclosure boxes. Next, perform the waterproof insulation test. The experimental results show that the Corning Fiber optic joint enclosure box does not achieve waterproofing. Although technicians from the company were invited to inspect the site, the results were not satisfactory. Some manufacturers have poor product operating instructions.

According to the instruction manual for the fiber optic joint enclosure boxes, “if the adhesive tape is degenerated, please don’t use it.” It is common to find that adhesive tapes with low viscosity, hard collloid, part yellowing, and poor ductility are used in engineering. This reduces the waterproof performance of the Fiber optical joint box.

The outer sheath of an optical cable can be damaged during transportation or construction, and water enters. As a result, the insulation of the cable to ground falls below the required standard.

Water inflow is also affected by the structural characteristics of the fiber optical joint box. Dome closure fiber optics are especially useful for rainproof performance on overhead poles.

Water ingress can also be caused by the location of fiber optic joint boxes. The installation location of the fiber optical joint box in the pipeline is located below the perennial water level. This means that water can easily enter the fiber optic box all year.

Construction on cloudy or rainy days

Another reason ground insulation index is affected by damping occurs during construction on cloudy or rainy days.

The monitoring cable in the fiber optical joint box is a cable connecting the metal sheath to the core of the optical fiber. It also includes a cable with a monitoring connection drawn from the fiberoptic joint enclosure box. The optical cable may be damaged by the quality of the cable and its production. Ground insulation performance

A number of preventive measures have been developed in light of the above-mentioned reasons. These include: Do not use expired sealing tapes, control the quality and safety of optical cable transport and laying so that it does not cause damage to its outer protective layer; select the appropriate fiber optic joint box for the laying method.

To avoid fiber optic joint boxes being submerged in water, the location should be above the water line throughout the year. It is important to increase the level of responsibility and operational efficiency of construction workers and to improve manufacturing operations.

We have created the “Operation Instructions for Fiber Optic Joint Box” to help manufacturers improve their operation and standardize the operation of optical cable joints. These are the specific steps:

To check if the surface of the fiber optical joint enclosure box has not suffered any defects, use a clean, intact box.

Count attachments

Check the fiber optic junction enclosure box for any missing or damaged components. You should dispose of any excess accessories in the fiber optic junction enclosure box. Corning fiber optic jointsenclosure box contains fiber optic cable sealant and plug shell. It also includes optical cable sealant, fiber optic connector box sealant and plug sealing clip.

3Mfiber optic joints enclosure box contains fiber optic cable sealant, plug rings, reinforcing core parts, and optical fiber fixing base plates. Ruikan fiber optical joint enclosure boxes has fiber optic optic joint box sealing ring. Fiber optic cable clamp, hose label paper, universal adhesive tape, optical tray universal adhesive tape, and optical cable heat shrink tube.

Clean fiber optic joint body and optical cable

To clean the contact surface, gluing surfaces and optical cable gluing surfaces of the two boxes of fiber optic joint enclosure boxes, use toilet paper or alcohol cotton. Clean the fiber optic box enclosure box that has been damaged or infiltrating with water with warm water. After drying, clean it with water and then dry with alcohol cotton. Clean alcohol cotton can be used to clean rubber with oil and fingerprints. You should not remove the protective sheet from the sealant before the fiber optic joint enclosure is sealed.

You must remove the aluminum skin from the direct-buried optical cables. The components that attach the optical cable should be 1 cm behind the section. To fix the 3Mfiber fiber optic joint enclosure box’s strength core, two plug rings must be used. The fiber optic cable should also be roughened using #80 coarse sandpaper.

The bottom plate should be securely fixed to the lower cover of fiber optic joint enclosure boxes. Screws should be tightened. The bottom plate is used to fix the optical fiber tray.

Make plugs

Use the provided scale to measure and cut the parts of the Corning fiber optic joint enclosure boxes. You must ensure that the cutting surface is smooth and free from burrs. Waterproof rubber is used to cover the contact area between the optical cable & the fiber optic joint box. Cover the optical fiber cable with glue and secure the plug. For the 3Mfiber optical joint enclosure box wrap the optical cable sealant between the two plug rings. The limit of the sealant is just beyond that of the plug ring. Ruikan fiber optical joint enclosure box doesn’t need to be plugged.

Place the reinforcement core in the reinforcement core fixing hole. Adjust the position of your cable head, and then tighten the screw. Adjust the position of the plug for Corning fiber optic joint enclosure boxes, then tighten the screws. For 3Mfiber optic joints enclosure boxes, insert the optical cable, reinforcing core installation pieces, and the optical cable into the card slot.

Inject the spliced optical fibres into each slot in the optical tray. Then, coil the excess optical fibres into an optical tray with a radius of at least 3.75 cm. Make sure the optical fibre is not too high above the edges. Close the optical fiber tray’s upper cover. Use a magic tape to attach the optical fibre tray to the optical tray fixing bottom plate.

Corning has a fiber optic box sealing rubber. The rubber should be placed in the limit groove of the Fiber optic joint box. Fill the contact surface between the plug, the lower and upper sealing rubbers of the Fiber optic joint box. To seal the fiber optic junction enclosure box, apply waterproof glue. Final, make sure that the sealing rubber is placed in the sealing groove. The 3M fiber optic box joint enclosure box must be sealed with the sealing glue. Seal the fiber optic joint box by using sealant between the plugs. Check that the sealant’s position is within the sealing groove. The fiber optic junction enclosure box can then be secured by wrapping it around the limit groove. Check that the position of your sealing ring is within the sealing groove before sealing your fiber optic joint enclosure box.

Corning fiber optic joints enclosure boxes can be sealed with more than 40 screws. You should tighten the seal symmetrically, from the middle to the sides. The force should not exceed 10 kg. A special 10kg force limiter is available for 3Mfiberoptic joint enclosure box or fiber optic joint enclosure boxes. The sealing should be tightened from the middle to both ends. This ensures that the heat shrinkable sleeves of the optical cables heat evenly and prevents them from cracking from local heating.

The Fiber optic joint box termite control is done in the field. This means that the construction conditions are often poor and that the drug is applied in large quantities. It is important to choose a drug that is simple to use, inexpensive, stable, and has long-lasting chemical properties.

Termites can be controlled by a variety of methods, including biological, chemical, and physical control. Depending on the current situation, termites can be controlled using the drug method.

Drug control refers to the use of a range of toxic chemicals through a specific method to release drugs into the habitat of termites. It is simple and straightforward. The drugs used can be poisonous. Some of them are extremely toxic and can easily pollute the environment and cause damage to people and animals. Effective protection measures are required.

The optical cable line is hidden in the wilderness. It must travel through villages, towns, rivers, and water sources. It must pass through towns, villages, rivers, water sources, etc. The environment is at risk from the improper use of drugs. It is important to use drugs with low levels of toxicity. Groundwater is difficult to dilute and remove. Medications with a long life expectancy and minimal environmental pollution.

It is humid in mountainous areas, which means it rains a lot throughout the year. The termite-control drugs used to protect optical cable lines are found in nature. They can be easily diluted by groundwater and taken out of the system. Oily and insoluble, diffuse Inappropriate drug. This is what we have discovered. The “851 (arsenic/copper mixture) was used to stop termites from constructing Hang-Fu Gui-Cheng optical cable trunk lines. It is a water-soluble solvent and it was quickly diluted by groundwater. This caused the fiber breakage accident.

The author was involved in long-term maintenance and came across a chemical agent that can seal the Fiber optical joint box and prevent termites infestation.The chemical agent is made of a variety chemical products (acrylammonium and triethanolammonium), according to a specific proportion. It can prevent the odor from the fiber optic joint box of the optical cables from overflowing. After sealing, it can be opened easily and maintained in future. This method is less expensive, requires no special tools to construct, is easy to use, and can be used on the ground.
Termites can cause damage to Fiber optic joints boxes by eating the waterproof sealant. This will affect the Fiber optic box’s waterproof performance and put at risk the safety and reliability for optical cable communication. All of the existing control measures can be resorted to using some type of treatment or device that can seal the Fiber optic box and create a barrier to the outside environment. This will prevent termites from getting into the fiber.

On-site Construction

Based on the dimensions of the Fiber optical joint box, dig a well that can hold the Fiber optic box. Then, place the Fiber optic box in the well.
The volume of the pit is used to determine the amount of configuration. After a brief chemical reaction, the chemical agent will become a solid. The Fiber optic joint box will then be solidified to create a complete unit. The environment outside acts as a barrier.

This chemical agent sealing control method can be used to prevent termites from entering the fiber optic joint enclosure boxes of optical cables.

How can you reduce failure of Fiber optic joint boxes?

The Fiber optic box is susceptible to damage by the elements when it is left out in the open. This makes maintenance more difficult. In the future, we will continue to investigate the causes of any other defects in fiber optic joint enclosure boxes. We can resolve the problems on the ground and reduce the failure rate for the fiber optic joint enclosed box by using the total quality management method. This will improve the efficiency of operation and ensure reliable operation of the optical fibre communication system.

Some optical cable reinforcements weren’t fixed before the rectification. This resulted in optical fibers being pulled from the fiber optic joint box. The optical fibers were then easily pulled and broken, which caused the optical cable transmission channel not to work. The bottom plate has opening screws that hold the reinforcing bar of the optical cables. This greatly increases the firmness of these reinforcing blocks.

The loose tube didn’t reserve the required length before rectification. This led to the cable core being exposed, which can be easily broken. The loose tube is now resized to the correct length. Additionally, the cable core is protected better by environmental and mechanical protection.

The factory’s construction staff made it easy to remove the card slot from the disk plate and attach adhesive tape instead. It was impossible to protect the fragile cable core connector point. Place the heat-shrinkable sleeves in the card slot of your disk board in a sequence after the rectification. Be sure to secure the connection points as best you can.

In order to increase the sense of responsibility among maintenance and operation personnel, inspect the line regularly, pay particular attention to the Fiber optic joint box condition, and report any defect. This item is part of the operation regulations.

Construction personnel must strictly follow the process throughout the construction work. They also accept inspections according to quality requirements after work is complete. This is done to improve construction quality and to ensure stability and reliability of optical fiber lines. Maintain the optical fiber splicebox, which is part of the operation and maintenance rules.

The fiber optic joint box is an essential part of fiber optic communication lines. It serves two main functions: it connects and disconnects the optical fibers of the Fiber optical joint box. Additionally, to ensure the Fiber optical joint box’s grounding function, the Fiber optical joint box’s internal grounding device must be connected to the grounding. The metal components of Fiber optic joints box must also be connected to the grounding. This is done to protect the Fiber optical joint box from environmental influences. Fiber optic joint boxes can be used in the same way as fiber optic cables. Their own quality is crucial for communication transmission.

Fiber optic joint boxes are primarily outdoors so their environment can be either buried, overhead, or pipeline.

The box body of the fiber optical joint enclosure box should have a thicker material and be able to withstand pressure. It is recommended that the box’s impact resistance reach 32N. This is because most direct burial methods are underground and it is not sufficient to meet 16N. The strength of the box body will not be sufficient if it is too thin.

The internal structure of the tray is acceptable. The optical fiber coil tray should be made of a loose-leaf rotating design. This is more convenient for construction and maintenance.

The splice tray frame must be large enough to allow for the maximum curvature radius of the optical fibre to be less than 40mm.

A sealing ring should be installed between the lower and upper covers of the fiber optic junction enclosure box. The fiber optic box enclosure is susceptible to micro-cracks. After water enters the fiber, it will eventually break. Most fiber optic box enclosure boxes are underground so you must prepare the box. seal. Seal the lower and upper covers of the fiber optical joint enclosure box by placing the sealing ring in the groove. Then tighten the screws to seal the box.

It is recommended that you seal the optical cables and fiber optic joint enclosure boxes by first grounding the jacket. The outer sheath should then be ground with gauze perpendicularly to the axial direction. This will allow the optical cables and sealing tape to be combined better. Seal better.

Fiber optic joint boxes are used most often in humid and high-lighting areas. Fiber optic joint boxes have very high insulation and lightning protection grounding requirements. The Fiber optic joint boxes should be used in combination with lower and upper insulating spacers. This will provide insulation between the metal components and the core of the fiber optical cable strength (the fixing bolt). 

The Fiber optic joint box must have a minimum “withstanding voltage strength” that does not allow for any breakdown or arcing phenomena within one minute of applying a DC voltage of at least 15KV. To ensure a reliable electrical connection between your internal grounding device (and the grounding portion of the optical cable), it is recommended that you install a reliable and professional lightning protection grounding device. The connection resistance must be less than 0.01O.

Double-holding steel ferrules are recommended for attaching the optical cables. This will ensure that the cable is securely fixed.

Today, fiber optic joint box products are often mixed on the market. Many inferior products have gotten into our communication network, some of them causing communication disruptions and failures. Many manufacturers are reckless and cut costs blindly in order to make high profits. This is regardless of the quality of their products. Guangdong Telecom compiled statistics about the problems with the Fiber optic joint boxes used online and discovered many.

(1) The fiber optic joint enclosure box material is too thin, and the strength is insufficient.

(2) Fiber optic joint enclosure boxes are not well sealed, and water can enter.

(3) Low product quality stability

(4) If the pallet position is too soft or brittle, it can be easily broken.

(5) The hose’s upper position is too small. This makes it easy to crush the fiber core.

(6) The chassis’ volume is too small for the required hoses. This poses a safety hazard.

(7) The steel hoop used to fix the optical cable is very thin.

There are specific problems:

(1) The splice tray chassis’ width is too small, which makes it difficult to conduct fiber coiling.

(2) The sharp edge of the metal disk on the splicing disc chassis can cause serious damage to the fiber core.

(3) Poor quality accessories (core heat shrinkable tubes) can cause unstable core attenuation.

(4) It is hard to adapt the design of the steel hoop to fix the optical cable to different sizes.

(5) Dome-shrinkable, sealed optical fiber optic. The distance between the optical cable fixing seat and the reinforcing core fix device is quite short. This makes it easy to break the optical core.

(6) The melting temperature of the nozzle in the fiber optic joint box is low. The heat shrinkable sleeves have not begun to shrink and the nozzle has melted.

(7) The fiber optic junction enclosure box does not contain a core strengthening device. This means that the optical cable cannot ever be fixed. The rotation of the optical fiber cable can cause the bundle tube to become twisted when the cable is being reeled or installed in the fiber optic joint box.

The barrel does not have a fixing device. Only the rod hoop and two expansion screws are attached. It is difficult to use and cannot adapt to all operating environments.

A fiber optic joint box provides optical continuity, sealing and mechanical strength between adjacent optical cable. It is used to connect optical cables in various laying methods, such as overhead, pipeline, direct burial, and branching. It is an essential component in the construction and maintenance of optical cable lines. It directly impacts the optical cable’s quality and its service life.

The fiber optic joint box can be divided in two types, dome closure fiber optic or horizontal fiber optic splice closure depending on the structure and shape. There are three types of optical cable laying methods: overhead, pipeline, and direct buried. There are two types of sealing: heat shrinkable and mechanical.
You can also divide it according to the optical cable in/out scale into one in, two out and two out and one in, two in, two out and one out and one in, three out and three out and even one-in and eight out.

There are two main types of Fiber optic joint boxes in communications. They are the dome closure fiber optic and horizontal fiber optic closure. These are used for underground direct-buried straight and branched optical cables, as well as field overhead and pipeline manholes. Figures 1 through 2 show horizontal fiber optic splice closure. Figures 3 and 4, on the other hand, are dome closure fiber optic.

The performance and quality of the fiber optic joint box, the parameters that are difficult to meet the standard, are mainly reflected in the shell material, sealing performance, adaptability to climate environment (high, low temperature, temperature cycle test), resistance to mechanical damage (vibration resistance, tensile strength, Compression resistance, impact resistance, bending resistance, torsion resistance) and lightning protection grounding device.

You can choose between a plastic or metal shell for the shell of the fiber optic joint boxes. The market has few metal casings, so most commonly used are PC plastic (resin), ABS+PC (resin), and other plastic casings. It is waterproof, water-resistant, heat resistant, flame retardant, and impact resistant.

Fiber optic joint boxes are capable of almost achieving optical fiber coiling with no additional attenuation. The radius of curvature for both types is >=37.5mm.

The horizontal fiber optic splice closure is structurally composed of two shells with large sealing areas and irregular sealing (as illustrated in Figure 2). Sealing ring, small, regular seal (seal groove in round shape),
The dome-sealing dome closure fiber optic’s horizontal fiber optic splice is therefore easy to accomplish. The dome closure fiber optic uses heat shrinkable sleeves, which have good sealing performance. However, the horizontal fiber optic splice closes with waterproof insulating glue. This firmness is reflected in the tensile strength out.

Many Fiber optic joints boxes are exposed to extreme and changing climatic conditions. This causes air leakage and decreases in sealing performance over time. Many Fiber optic joint boxes showed air leakage during the temperature cycle (-40 to 65). This indicates that the Fiber optic joint boxes’ thermal stability is low and that their sealing performance is affected by changes in temperature or climate.

The pass rate of horizontal fiber optic splice closure is generally lower than that of dome closure fiber optic cables connectors.
At room temperature, the horizontal fiber optic splice does not leak any air. Air leakage is possible after the temperature cycle test. The box’s air pressure drops. The sealant can no longer be sealed because it is too soft.

Resistant to mechanical damage

Some Fiber optic joint boxes casings suffered cracking and damage during transport and vibration testing. Part of the fiber optic box was damaged and deformed during the tensile testing. Figure 6 illustrates the problem of poor product quality during the tensile testing during arrival inspections of company products. Individual Fiber optic joint box cases were cracked during the impact test.

The laboratory dielectric strength test is done, and Fiber optic joint boxes can usually meet the high voltage shock resistance (>15kV) of the lab. There are rare cases of lightning damage in actual use.

ODN is an integral part of PON (Passive Optical Network). Splitter is used in FTTH (Fiber To the Home) to split light. A large number of user-optical fibers are pulled out close to the user. These products are very similar to ODF wire products. There are differences. The number of users accessing the network is high, it is complicated, expensive, and difficult to maintain. This means that wiring products play a growing role in FTTH. Only good wiring solutions can guarantee the access network. Stable, reliable and long-lasting operation.

A Fiber optic joint box is required to connect and schedule optical cables and optical fibres in an ODN network. This includes the nodes of trunk optical cable and distribution optical cable as well as the nodes for drop optical cable and distribution optical cable. The Fiber optic joint boxes can also be used to splice and terminate optical fibers. Storage, scheduling and storage functions. Both the dome closure fiber optic or joint closure box are suitable for various applications, including overhead, pipeline and direct burial of outside facilities.

Network reliability is guaranteed by the quality of the fiber optic joint boxes. A reliable and stable network will provide high-quality services to users, increase user satisfaction, and improve user loyalty. High-quality Fiber optic joint boxes are required for all-optical city construction in coastal areas that have as many typhoons, rainy and hot.

Reliable brands and high-quality Fiber optical joint box products should be first choices in ODN network construction. This will not only reduce enterprises’ operation costs but also increase their brand influence and user loyalty.

Construction of all-optical metropolises dominated by FTTH has led to a significant increase in the number of optical cables and has also challenged the design of optical cable networks. The fiber optic joint box model of one-in-multiple out can improve the flexibility and cost effectiveness of networking. It can also reduce the need for investment and maintenance costs.

Fiber optic joint boxes often fail due to poor quality equipment. This can be caused by insufficient construction personnel not following the instructions for installation, or installing the locking parts. Or because the installation process is complex and the key links are not well understood. It is important to choose high-quality, easy-to-install Fiber optical joint box equipment. However, it is also important to increase the quality of construction workers to prevent network failures due to human factors.
