A Brief Overview Of Fiber Optic Splice Closure

Introduction:
The Fiber Optic Splice Closure, also called the fiber optic cable connector box and the barrel, is the place where the end of the optical cable is connected, and then accesses the optical switch through the optical fiber jumper to prevent the aging of materials caused by heat, cold, light, oxygen and microorganisms in nature. And with excellent mechanical strength, the sturdy cable connector housing and main structural components can withstand * harsh environmental changes, while at the same time playing a flame retardant, waterproof, shock, impact, cable tension, distortion and other protection.
According to the structure, the connection box can be divided into two types of optical cable connection boxes: a hat type (vertical type) and a horizontal type (have type). Moreover, when there are certain technical requirements for the design of the optical cable connection box, what technical requirements are there?
The cable connection box can be installed in the overhead, buried, wall and pipe wall of the well; the box seal and the cable inlet and outlet holes are sealed quickly and easily, and can be repeatedly opened and used; the connection box has a good fiber routing design to ensure the radius of curvature of the fiber. The fiber storage space is large; the welding splice tray is selected, suitable for cable or integrated bundled fiber, and can be equipped in any capacity within * capacity; the splice disk has large storage space, the flip angle is greater than 90°, and the maintenance and expansion are convenient; the internal cable is fixed structure. The cable is fixed safer and secure; the grounding device and the valve can be installed.

In order to improve the withstand voltage performance of the connection box, it is necessary to use a better insulating material to increase the surface finish and reduce the curvature between the insulator and the pole and pole and between the pole and the ground.

This condition can be increased by at least 100% or more in the case where all other parameters are the same. The connection box is an important part of the optical cable communication line. The main function is to complete the connection of the optical fiber, and to ensure the grounding function of the connection box, the internal grounding device and the grounding part of the optical cable should be in electrical communication, and the metal components of the connecting box and the grounding device and the optical cable reinforcing core are insulated from each other. To prevent the effects of helium from the joint box from the environment.
Because the application environment of the joint box is basically outdoors, their application environment may be buried, overhead or pipeline. Therefore, high requirements are placed on the design of the fixing and grounding device of the connection box and the insulating material used.

Possible Dangers Of Fiber Optic Splice Closure

Green Telecom is a company specializing in the production of communication equipment, including Fiber Optic Splice Closure, Fiber Closure, Inline Closure , etc.

Damage caused by the cable discussion box:

The discussion of optical fiber strengthens the hot melt temperature of the materials and supplements received by the cherished pieces at 120 ° C, the thermal softening temperature is 90 ° C, and can be temporarily used at -40 ° C ~ +60 ° C temperature. Its primary function is to realize the continuation of the fiber optic cable, and to discuss the grounding effect of the fiber optic cable. The internal grounding assembly and the grounding part of the optical cable should be in electrical communication, and the metal components and grounding assembly of the optical cable discussion box and the optical cable reinforcing core are included. Between each other, in order to avoid the impact of the situation on the cable discussion box. In the case of indecent, because the use of optical cable discussion boxes is based on the outside, their use is mostly buried, crowded or pipelined. In order to guard against the impact of lightning strikes or other identities, it is required that the “voltage withstand strength” of the cable discussion box must meet the requirement of 15 volts DC voltage in the scale, no breakdown within 1 minute, and no arcing sign. Therefore, high requirements are placed on the planning and application of the flow and grounding assembly of the optical cable discussion box. The quality of the lightning protection facilities indirectly determines the probability that the cable junction box will be hindered. After the construction is laid, the test is for the inspection and release process, and it is used as a check before the continuation; the test in the continuation is to check whether the low consumption is reached; after the continuation, the test of the unit cable segment is completed. It is in the process of checking whether it is the preparation of the total attenuation of the transmission and the corresponding requirements of the total baseband, as a preparation for the total adjustment of the adjacent optical transceiver. Single mode fiber is characterized by a dispersion coefficient to characterize the dispersion. In addition, the new architecture introduces the principle of multi-fiber business terminals (MST) and meeting splices, and the cable discussion box further reduces initial support costs. Finally, when the technicians are protecting, repairing, and opening business, the two basic areas that are being collected by the FTTP—the interface between the feeder segment and the distribution equipment—the interface between the equipment and the outdoor fiber optic cable of the outdoor equipment— Using the adjacent device will make the access easy and low.

5. When the cable connector box bottom box is installed with the suspect module and the power socket at the same time, the spacing and the receiving protective facilities should meet the plan requirements.

6. The flow method of the optical cable discussion box base should be determined according to the detailed premise of the on-site construction. It can be installed by shrinking screws, nails and other essentials. The flow requirements of the bottom box of the doubt module are determined by the premise of the construction site.

7. Install the fiber optic cable discussion box on the wall, and its position should be more than 300 mm in the air. When the local board is being accepted in the air in the room. The cable terminal box should be 300 mm outside the local board.

8. The flow screw needs to be tightened, and no loose signs should occur. The installation of the base, the suspect module and the panel should be firm and stable, and there should be no signs of looseness. The panel should be connected to a certain extent, so that the panel is neat and tidy.

Insulation Adjustment Strategy of Fiber Optic Splice Closure

Fiber optic splice boxes, also known as Fiber Optic Splice Closure and lens barrels, are suitable for straight-through and branch connections for overhead, pipe, direct burial and other laying methods for various structural cables. In optical communication networks, due to the limited length of the cable and the need for the cable to branch on the transmission line, the fiber optic cable connector is created, and the fiber connector closure provides conditions for connection and branching. Cable and protect the connector.

At present, the application of the optical fiber connector box is very extensive, but the insulation problem of the fiber connector box has always been a major problem, and the dielectric properties and plasticity of the material itself have been combined to make a suitable choice. Therefore, the structure and material of the insulation as well as the surface condition also have a great influence on the withstand voltage strength performance of the fiber splice case.

If you want to improve the pressure resistance of the fiber splice box, you must use a better insulating material, such as Teflon, to increase the surface finish and reduce the curvature between the insulator and the rod and rod and between the rod and the ground. . Insulating gaskets commonly used in fiber optic splice closures typically consist of two upper and lower spacers. The upper washer is a recessed washer and the lower washer is a male washer. Since the fixing bolts are connected to the reinforcing core of the communication cable, the upper and lower insulating spacers are combined to form an insulation between the metal member of the optical fiber joint box and the cable reinforcing core (ie, the fixing bolt). In the compressive strength test, a DC voltage of 15 kV is applied between the fixing bolt and the metal member. Most materials used for insulating gaskets are high molecular polymers. The main feature of this method is to improve the combination of the upper and lower washers.

Fiber Helps To Close The Fiber Optic Connectors Work

Simply put, the fiber optic splice closure connects a cable to the different lengths of the same type of cable. This is sometimes called online blocking or tracking joints. The additional function is provided by a branch (or branch) connector that divides the cable into two ongoing sections – the main cable and the side or branch. There is also the end of the route closure, where the cable is broken down into separate components for the customer or telephone connection.

Before installing the fiber optic splice closure, you must know some precautions. First you have to know your stitching closed application. Is it installed in the air, or is it buried? Know your stitching count and stitching type – how many fiber connectors need to be closed? Are they a splice, a mechanical joint, or a combination of both? You can use additional sealed ports to purchase some of the closures that can be opened to accommodate new fibers that may be added in the future.

Make sure that the cover and the application match the correct type of splice tray. For example, if you are using ribbon fiber, make sure that the closure can accommodate the design of the ribbon tray. Many newer covers can be sealed without the need for sealed tape or C-type cement. This makes it easy to seal the closure and re-enter the work that requires future work.

Multiple Seals are made of a diastolic material using a compression washer that provides a tight seal when the two halves of the seal are connected together. I recommend using a cruciform star pattern when tightening the bolts to ensure that the pressure is applied evenly to the compression seal. Cable entry and exit around the grommets can be ordered with various apertures to accommodate different cable diameters.

Some of the fiber optic splice closures have an accessory that allows the installer to fill the sealed seal with compressed air to determine if there is a leak. Seams can be used for soap solutions, and if air leaks, bubbles are displayed.
