Fiber Optic Splice Closure, also known as fiber optic cable connection box, is mainly used for the link and combination between optical cables. The appearance of the box is relatively high, very hard, corrosion resistant, long life and easy to use. With Fiber Optic Splice Closure, the direct connection of the cable is much easier and safer to construct.
The exterior of Fiber Optic Splice Closure is made of high-strength accessories, so that no matter how hot the summer sun is, the weather is cold in winter, the material will not age, if it is hit, it will not break, and the stretching performance is better, it will not be damaged. After elongation, the material becomes thinner and then ruptures. Conversely, the higher the temperature, the better the tensile properties and the higher the strength resistance compared to other items.
Fiber Optic Splice Closure is also waterproof. If the drip can be worn, this will greatly reduce the life of the Fiber Optic Splice Closure. Because the material is better, this problem can be eliminated. In addition, the Fiber Optic Splice Closure also has a shock-proof function, which increases the safety of use, and does not collapse, squeeze, twist and deform, so the Fiber Optic Splice Closure can be intact under so many difficulties.
What is the role of the optical cable connection box in optical cable communication:
With the development of the times and the improvement of people's consumption level, our requirements for communication are increasing.
As a cornerstone of the optical cable communication system, the optical cable connection box has played its role, and therefore, the optical cable connection box is well known and recognized by more consumers.
So, what role does the fiber optic cable connection box play in the fiber optic cable communication system? Let's take a look!
The fiber optic cable connector provides a protective connection between the fiber optic cable and the pigtail. The optical cable metal member is insulated from the cable end housing, and the grounding can be conveniently led out to provide the space for the cable terminal to be placed and the space for storing the remaining fiber, which is convenient for installation operation, and has sufficient impact strength to fix the box body, which is convenient for different use occasions. Installation, you can choose a variety of installation methods such as wall mounting or direct placement in the channel.
The optical cable connection box is widely used in local telephone, agricultural telephone network system, data and image transmission system, CATV cable TV series, for the direct connection and branch connection of indoor optical cable, and functions as a tail fiber storage and protection joint. Cold rolled steel plate

Optical cable connection is an important part of the construction of optical cable lines. The quality of optical cable connection directly affects the construction quality and affects the quality of optical communication. Improving the quality of optical cable connection is very important in line construction, so this article will address several issues that should be noted in the connection of optical cable.
1. Pay attention to the depth of the feed when the cable is stripped. The key to the stripping of the outer sheath of the cable is to master the depth of the sheath cutter, otherwise it is easy to break the fiber. In actual operation, the sheath cutter should be rotated while observing the incision. If the white polyester belt can be seen, the feed should be stopped and the cutter removed. This step is a skilled process and requires multiple exercises to master the depth of the infeed.
2. Fixation of the optical cable and stripping of the core bundle tube. After the cable is stripped, fix the cable in the cable connector box, open and strip the core tube, and prepare for the fiber fusion.
At this point you should note:
a) The core bundle tube cannot be twisted. Before fixing the optical cable, you must pay attention to the position of the core tube. When the reinforcing member passes through the fixing screw, the underside of the reinforcing member must be a filling beam tube. It cannot be a core tube. The core tube must be in the reinforcing member and enter the fiber. The same side of the receiving tray cannot be twisted on the reinforcing member. If the reinforcing member is pressed on the core bundle tube, the deformation of the core bundle tube will cause excessive loss, and the optical fiber in the core bundle tube will also be broken due to long-term stress, leaving a hidden danger to the project.
b) The length of the reinforcement should be appropriate. Once the position of the core tube is determined, the cable can be secured. The cable must be fixed so that the position of the fiber in the connector box does not become loose, and the fiber loss or fiber breakage problem may be avoided due to the movement of the cable position. The fixing of the cable is divided into the fixing of the reinforcing member and the fixing of the rest of the cable. The fixing of the reinforcing member should pay attention to its length, which is too long and cannot be placed in the joint box; it is too short, and it is not suitable for fixing the optical cable. Generally, when cutting the reinforcing member, the distance between the clamping plate of the fixing cable and the fixing reinforcing member screw should be equivalent to the remaining length. The rest of the cable is fixed after the reinforcement is fixed, and the clamp is screwed tightly and fixed tightly at the cable entrance of the connector box.
c) The length of the stripping of the core bundle tube should be appropriate. After the cable is fixed, the core tube can be stripped. If the stripping length is too long, it will reach the groove of the fiber heat-shrinkable tube, and the fiber will be damaged when the fiber is used. When the stripping length is too short, when the core tube is fixed, the fixing clip will be stuck on the fiber, which will easily damage the fiber. . Therefore, it is generally preferred to peel it off after two fixed bayonet mounts. In this length, the core bundle tube does not cause damage to the optical fiber and can be well fixed. However, when the clip is fixed, the clip cannot be over-tightened, otherwise the fiber of the core bundle tube will be lost due to the force, and the fiber will be broken after a long time, leaving a hidden danger to the project.

Green Telecom is a company specializing in the production of communication equipment such as Fiber Optic Splice Closure.

For cable connectors, the following should be defined:
1) The zigzag radius of the cable joint should not be less than 15 times the outer diameter of the cable, and should not be less than 20 times during the construction process.
2) When the cable is in the traction mode, the traction should not exceed 80% of the allowable tension of the cable. The main traction should be applied to the reinforcing core of the cable. The maximum traction at this time does not exceed 100% of the allowable power.
3) The A and B terminals need to be placed in the bias cable using fiber optic cables.
4) When setting up the cable connector, the cable must be discharged from the top of the cable and connected to the arc. The cable arming process should be unchanged, and it is strictly forbidden to buckle back the ring, surge and other signs.
5) When the machine is laid, the speed limit of the tractor is 0~20m / min, stepless speed regulation. The traction tension can be adjusted. When the traction exceeds the set value, it should be able to actively alarm and stop the traction.
6) When using cable joints, the speed should be symmetrical, the same conventional control is 10m / min, and the traction length should not be too long. If the cable is too long, it can be divided frequently.
7) In order to ensure the quality and safety of the cable joints, the construction process must be carefully constructed and approved by personnel. Must have good and good connection skills (something), and it is strictly forbidden to do work in an unconnected environment.
Cable connector physical characteristics
Cable connector and wire diameter / mm outer diameter / mm cross-sectional area / mm2 mass / (kg / km) unit strength / (N / mm) minimum total tensile force / (N / mm) elastic modulus / (102Kg / m) Linear Shrinkage Factor / °C 7 / 3.0 9.0 49.5 400 1200 54500 1.7~2.0 1.2×105 7 / 2.6 7.8 37.2 300 1200 41000 1.7~2.0 1.2×105 7 / 2.2 6.6 26.6 210 1200 29300 1.7~2.0 1.2×105 Project Planning principle
1) The project plan must implement the country's fundamental support goals and communication skills economic policies, and exercise funds on a fair basis. The situation is very cherished.
2) The project plan must ensure communication quality, advanced skills, economic fairness, safety and practicality, and can meet the requirements of construction, production and operation.
3) The plan should carry out multi-program comparisons, the growing demand for near-term and long-term communication, and the rational use of existing collection methods and equipment to ensure the project's target economic and social benefits, and to reduce project costs and protection in a timely manner. 4) Products accepted in the plan must meet national scale and industry standards. Products that pass the test through experiments and judgments shall not be used in the project. Continuation of fiber optic cables 1) The continuation of fiber optic cables should normally accept openable sealed cable discussion boxes. 2) As usual, the fiber should continue to be welded. 3) The continuation of the fiber must be reinforced by reinforcement. 4) The cable metal reinforcement core can be electrically connected.
5) The discussion box must have a superior waterproof sealing function, and its mechanical strength and corrosion resistance should be sufficient for engineering design.
6) The fiber continues to be evenly consumed at a rate of 0.05 dB per point, with the most expensive consumption typically being 0.08 Db.
Cable becomes a skill requirement
1) The installation location of the cable junction box should be safe and reliable, away from heat sources.
2) A discussion about the death of fiber in the junction box should be accepted to discuss and cherish the facilities that flow. The radius of curvature of the remaining fibers when coiled in the box should be a certain value.
3) The adjacent equipment of the single-core cable or the tail cable of the cable junction box should be inserted into the adjacent socket of the optical distribution (ODF) as required. Adjacent devices that are temporarily used should use the upper end to prevent dust from eroding the photosensitive surface of adjacent devices, resulting in adjacent device consumption.

Fiber optic splice closureis a device for providing space to fuse fiber and to provide protection for spliced fiber splice points and fiber optic cables.It can protect the fiber optic connector, while providing fast and easy without re-entry. Seal with fiber connector tray. The fiber is fused and placed in the fiber optic connector tray for protection. The closure itself is then provided for further protection. Historically, the use of closed parts in fiber-optic networks is a large over-designed structure, its installation and re-entry costs are high and complex. They are usually installed and serviced by elite teams within the telephone company that are separated from the copper service personnel. As the fiber moves further, the division of duties and expertise becomes impractical and expensive.

The fiber optic splice closure is a device used to provide space for the spliced fiber. It also provides protection for fused fiber connectors and fiber optic cables. There are two types of closures: vertical and horizontal. A wide variety of fiber optic connector closure designs are designed for different applications such as antennas, ducted cables and buried. In general, they are usually used in outdoor environments, even underwater use.

The biggest challenge for any closed system is to easily separate several fibers from the large fiber number of ribbon cables and expose the rest without affecting any bending radius. The ribbon is the most difficult type of cable to be handled because it is so stiff and small that the twist may damage the external fibers.

With the development of fiber optic networks, the flexibility of the unit is another major requirement. Due to the large differences in the fiber architecture, it is necessary to equip the unit to handle some wiring to ensure a smooth transition when splicing and change are required. The number and diameter of the cables may be different in each installation, and the joint may be mechanical or fused to the fiber in a discrete or ribbon configuration. Closed design goals should be adapted to many options while maintaining the same basic components and installation practices.

Fiber closureis normally used for outdoor cables; they provide space for splicing together with outdoor fiber optic cables. The fiber optic connector closure and the internal fiber tray will protect the splice part of the spliced fiber and outdoor cable. Typically, the fiber optic connector closure is dome and horizontal. Dome optical fiber connector closed type cable is generally divided into two types, one is heat shrink type, the other is a mechanical seal type. The type of heat shrinkage means that the heat shrink tubing is achieved by a seal between the cable and the cable. Mechanical seal type, between the cable and cable through the deformation of the sealing ring cable will be discharged from the pipeline, the mechanical way for the compression seal ring, filled in the cable between the cable and the tube.

For fiber closure in the fiber optic cable, can be for the local weather and terrain and other natural conditions. Through the analysis of the closure of the fiber dome in these years, it is found that the following problems should be paid attention to in the construction and maintenance of the optical fiber joint closure.

The fiber closure is usually closed with a reinforced core, and the connection of the metal plate is better than that of the bolt, and the horizontal opening of the bolt is better than the vertical slotted structure, which is the choice of the fiber connector Attention to the problem. Aerial fiber optic splice closure of metal parts, should it can be to every 2 km of grounding, grounding metal parts directly to ground or through proper surge protection grounding, such steel strand has protective effect of overhead ground wire.

For the cable grounding of the telecommunication office, the metal part of the cable in the fiber closure shall be connected, and the core, moisture barrier and armored layer shall be connected and maintained. At the end of the unit (station) armor layer, strengthen the core should be grounded, moisture-proof layer through the arrester grounding. For fiber optic cable without copper wire, according to the provisions of YDJ14-91, in the fiber optic cable moisture-proof layer, armor layer and strengthen the core should be broken, not ground, ground insulation, cable cable to avoid the accumulation of lightning current. Practice has proved that this method is simple and effective, usually, the fiber optic cable in the metal parts of the insulation value is higher, lightning current is not easy to enter the fiber optic cable, in order to avoid joint protection cable damage.

GreenTel provides various shapes Fiber Optic Splice Closure. All the closures we offered are with a great sealing performance. High quality plastic material also ensures the durability whether the closure is in air, in pipeline or buried underground.

In order to prevent the Fiber Optic Splice Closurefrom entering the water, preventing exposure to aging and prolonging the service life, it is necessary to do maintenance work so that the incidence of problems can be effectively reduced.

There are a few things to keep in mind when maintaining the cable connector box: After each rain, the cable connector box is burned down, and the repair work will be very large. In fact, the cable connector box is easy to enter the water because the space inside the cable connector box is too small, there is no extra space to place the waterproof bend, and the 35mm power supply line is fixed with a plastic expansion tube, so that the waterproof measures are not in place, and the rain will follow. The cable is left in the connector box, and the terminal block is wetted. Because the gap between the terminals is small and the insulation effect is not good, it is easy to short-circuit.

In addition, the design of the cable connector box itself has surrounding heat dissipation holes and wiring holes, and the design originally used for the heat dissipation wiring becomes a defect at this time, and the cable connector box becomes easier to enter the water in rainy days. In this case, it is necessary to regularly check the maintenance cable junction box, press the wires in the cable connector box in time, and replace the damaged or aged wires in time. If there is not enough space, install the connection box in time to prevent too much internal wiring. The space is too small.
