This article examines first the reasons Fiber optic splicing closes, then identifies the benefits of fiber optic connectors in Fiber optic closure. How to use. This is a valid reference.

The construction and maintenance optical cable lines are dependent on the quality of optical cable connections. The transmission and use quality communication lines are directly affected by the quality of the optical cable connection. It also affects equipment reliability after repairs to optical cable junction boxes.

Fiber optic connector is a more reliable tool than traditional optical fiber-fusion splicing. It has the advantages of cold splicing and speed, as well as reliability.

The fiber optic splicing closing is an essential component of an optical cable line. It protects the optical fiber connection and transmits information.

Fiber optic splicing closure can be affected by subjective and objective variables. This could result in an interruption of optical fiber connections, poor communication quality or inability to connect, which severely affects social operations.

Fiber optic splicing is a normal operation. To ensure that emergency repairs are done quickly and efficiently, optical fiber splicing is an important topic.

The main causes of failure in Fiber optic splicing closure

Splicing Closure1

Two main causes of failure in the fiber optic splicing enclosure are: These are: lightning strikes, strong winds and floods. The fiber optic connection can be disconnected when the Fiber optic splicing enclosure’s interior is damaged by natural forces.

First, subjectively, it is not possible to verify that the Fiber optic splicing closing has the correct materials and workmanship. Fiber optic splicing enclosures are made from inferior materials or recycled plastic. Low temperature environments can cause cracking of the Fiber optic splicing container. The Fiber optic splicing container’s fixing clips cannot be fixed effectively. Also, the Fiber optic splicing chamber sealant cannot stop termites biting.

Second, poor quality construction workers can lead to inadvertent installation of fiber optic splicing shieldant and insufficient tightness of bolts and nuts. This leads to poor sealing that is susceptible to frequent failures. .

Two fiber optic connectors in Fiber optic splicing close have many benefits

Quick installation, high reliability, and stability

It is essential to perform good optical fiber splicing in order to ensure that the Fiber optic closure is used properly and that emergency repairs are done as soon as possible. Fiber optic connector is a novel type of connection under cold splicing technology. It has many advantages.

Installation is quick and easy. There are no complicated procedures to follow during installation. Following the instructions can quickly crimp the optical fiber after it has been cut and stripped. The repair and installation can be done in under 2 minutes.

The clamping element of an optical cable splicer is made from elastic metal material. It will not deteriorate and the temperature will have little effect. Furthermore, the anti-loose mechanism greatly enhances the device’s anti-vibration, anti-drop and anti-vibration performance. The distance between the two sections is nearly zero, which ensures that the connection remains stable.

Strong versatility suitable for many coated optical fibers

The fiber optic connector’s versatility is another great benefit. The fiber optic connector offers a more user-friendly alternative to traditional fusion splicing methods. The splicing process is fast and cold. The “cam” locking device, which is free of adhesive, is used for the splicing process. It is extremely simple to connect.

The fiber optic connector is versatile enough to be used for connecting single-mode and multi-mode fibers. It is also compatible with a wide range of coated fibers and has a remarkable connection effect. Fiber optic splicing closure emergencies repair can significantly reduce problems like poor connection effect or long repair times caused by different fiber types.

The insertion loss of the non-buried optical fibre structure is low and adopted

The fiber optic connector uses a non-embedded optical fibre structure and matching paste. After clamping and installation, the optical fibre connection’s insertion loss problem can be avoided. The optical fiber connector has only one docking point. This is less than the loss of the existing optical cable quick connector.

The axial belt positioning mechanism within the internal structure ensures that the optical fiber is not moved forward during clamping.

The data shows that the average loss for a fiber optic connector is 0.15dB. However, even if the connection is made randomly (without precise alignment), it can easily fall below 0.5dB. It can be used for 250/250 m or 250/900m splicing occasions.

The insertion loss of the non-buried optical fibre structure is low and adopted

It is easy to install and maintain the fiber optic connector. Construction personnel can use standard construction tools to install the fiber optic connector according to the instructions. Maintenance costs and time are also low.

However, it is also relatively inexpensive to manufacture and sell. It will not require high maintenance costs.

The fiber optic splicing application will undoubtedly become the standard in the market due to its simplicity and ease of repair.

Emergency repair of fiber optic splicing closure by 3fiber optic connector

Implement fault breakpoint test positioning

Fiber Optic Connector1

It is important to first test the fiber optic connector to determine the fault point. Then, use technical means to locate the fault point and carry out emergency repair construction. Transmission monitoring personnel perform fault breakpoint testing using the test system and immediately repair personnel once the breakpoint has been identified.

If the fault location is not clear or cannot be determined, it is worth turning on the Fiber optic splicing box closest to the fault to run two-way tests. Long fiber optical cables and emergency microcables are useful for emergency repairs. If the fault point is clear and the cables from the older cables are sufficiently long, then the optical cable section can be removed and the new joints used to fix the breakpoints.

Follow these steps to troubleshoot

Once the fault breakpoint has been determined, the fiber optic in the Fiber optic closing is connected according the repair and connection steps. To ensure that optical fiber communication is restored as quickly as possible, it is important to follow the principle of “first pass first, then fix”. To protect and lock the fibers, insert the fibers into the splice.

First, remove the optical cable sheath. Next, open the bottom optical fibre positioning groove with fiber stripping tools. Finally, insert the optical fiber into the groove. Close the upper cover and lock the optical fiber clamping slider. Install the fiber optic connector in the Fiber optical splicing enclosure’s card slot and secure it with the Fiber optic closure.

Follow-up maintenance and repair confirmation troubleshoot

The emergency repair confirmation work should be completed after the emergency repair construction has been completed. To confirm network recovery, the on-site emergency personnel must contact the transmission monitoring personnel. The emergency repair will be completed if the network is back to normal. Check the continuity of the network and determine if there are multiple fault breakspoints.

Also, check the Fiber optic splicing box to see if there are any problems like poor sealing or damage to the outside. Again, the splicing enclosure failed.

Cold splicing is a faster and more reliable connection method for fiber optic connectors than fusion splicing. It also has lower repair times and economic costs. As an emergency repair splicing accessory, optical cable splices are recommended to improve the efficiency and effectiveness of fiber optic splicing closure.

Follow the “Installation Instructions” for specific applications. Perform fault breakpoint testing and location, rush construction operation, fault repair confirmation, and follow up maintenance to ensure safety and reliability of your optical cable lines.
