How to Choose the Ideal Fiber Optic Splice Closure?

Nowadays, the high-speed development of the communication network, whether it is installed at home fiber optic broadband or cell phone used 5G signal, all rely on the powerful optical communication technology. In order to accurately and safely enter the world's thousands of corners of the optical signal, the continuous progress of communications equipment is particularly important. Today for you to briefly introduce the transmission of optical signals can not be separated from a tool - fiber optic splice closure, as one of the most important equipment in the communication equipment, fiber optic splice closure status is important, because it can directly affect the quality and service life of the fiber optic cable route.

1.The Importance of Fiber Optic Splice Closure

Fiber optic splice closure is a fiber optic cable line project construction must be used in the equipment, it is two or more fiber optic cables are connected together, and the fiber optic splice part to provide complete protection. Once the box is damaged, or due to all kinds of weather causes water leakage and other circumstances, the internal fiber optic cable will inevitably be damaged. For example, once the water leakage, in the cold weather is very easy to produce the internal freezing situation, which will directly affect the use of optical fiber.

From the majority of applications, communication line failure, in fact, most of the quality of the fiber optic splice closure can not be separated from the situation, such as the inability to resist the bad weather, the box thermal expansion and contraction, poor sealing and other reasons. Therefore, this is why the fiber optic splice closure needs to be very hard quality, note that the "hard" here does not mean hard, but means that it needs to have a variety of durable qualities, such as its ability to withstand extremely high or low temperature environment, the impact resistance to reach the level of IK10 +, to meet the IP68 protection level (the highest level of connector waterproof rating standard). Connector waterproof grade standard of the highest level), at the same time need to have strong sealing, insulation, good resistance to alkali and salt corrosion and aging resistance, and tenacious resistance to the performance of the field environment. Currently on the market most of the box for the engineering plastic material, performance to meet the service life of not less than 20 years.

2.Composition of Fiber Optic Splice Closure

The sealing method of fiber optic splice closure is mainly mechanical, heat shrinkable, breathable and gel, etc. The sealing strength directly affects the safety performance of internal fiber optic cable use. Fiber optic splice closure can be buried, aerial, pipeline, into the well wall, hold the rod use, so the splice box is widely used in our life. The structure of fiber optic cable splice closure consists of 4 parts: shell, internal components, seals and fiber tray. Shell to provide protection, the internal components to provide support, fiber optic disk for the fiber "deployment" to provide the perfect place. Internal fiber optic layout is also very important, requiring strong flexible wiring, so that the fiber can be transferred between the various disks to meet the conditions of optical signal transmission. If the optical fiber splicing is not standardized, the fiber optic layout is very chaotic, and even the emergence of winding messy situation, for the transmission of optical signals impede self-evident.

3.Fiber Optic Splice Closure Style

The type of fiber optic splice closure is divided into cap type, horizontal (Hafu type), page and other styles, these styles have been constantly reformed and improved, the design of the cable in and out of the mouth is also a lot of, it is very convenient to use.

Here is a special introduction to the flip page style, open it as easy as opening a book, it adopts the buckle type encapsulation, no tools can be repeated to open the box can be shortened by 80% of the box encapsulation time, which will greatly reduce the construction and placement of the time to enhance the efficiency of the construction workers. In addition, the shell can be installed on the valve, which can be used to inflate and measure air pressure according to the actual situation. At the same time, the interior of the fiber optic splice closure is required to have appropriate space, which can be used to place the fiber optic connector and storage of the remaining fiber, so that the optical fiber to avoid damage due to the internal environment and affect the use.

Next, let's look at some inline type fiber splice closures, are a kind of multi-purpose optical cable connection product, which can connect and divide optical fiber. The box can be applied to a variety of optical cable (loose sleeve, skeleton, ribbon, etc.) and can be installed in a variety of environments (overhead, wall, pipe-line, manhole, underground), and for a variety of connecting methods (distribution, bridge, branch, etc.). In addition, we have a range of patented boxes with cable sealing terminations, which use gel-sealing technology instead of plain rubber seal.
