Surface And Internal Structure Of Optical Cable Terminal Box

The optical cable terminal box is an auxiliary equipment for terminal wiring in optical fiber transmission communication networks. The optical cable terminal box, abbreviated as OTB, is a box used to protect the optical cable and tail fiber fusion splicing at the terminal of the optical cable laying. It is used for the direct connection box branch connection of indoor optical cables and the fixation of optical cable terminals, playing the role of tail fiber storage and protection joints.
The material of the optical cable terminal box body is made of cold-rolled steel plate, which is a high-quality cold-rolled steel plate with a thickness of 1.0mm and has undergone oil removal, rust removal, phosphating, and passivation treatment.
Terminal box surface structure: screw lock, which not only saves costs, but also facilitates installation and maintenance.
Outgoing device: can be used for various connectors such as SC, ST, LC, FC, etc.
Inlet rubber screen: protects the fiber optic cable and prevents scratches.
Supporting rubber particles: used to support walls and play a balancing role.
Internal structure:
Fiber optic cable fixing bracket: used to fix fiber optic cables for easy installation and maintenance. Used to fix the fiber reinforcement core, reduce the tension of the fiber, and extend the service life of the fiber.
Melt fiber disc: The function of air melt fiber, protection, and specification of tail fibers.
Instructions for use:
1. Unscrew the screws on top and open the cover.
2. Reserve the optical cable to be fused, fix the steel wire inside the cable to the front bracket, and secure the cable to the cable inlet
3. Peel off the reserved optical cable and fuse it with the tail fiber using a fiber heat shrink tube, and fix it in the fusion disc.
4. Cover the upper cover and tighten the screws.
The fiber optic terminal box brings us the work efficiency of fusion splicing of optical fibers, fusion splicing of optical fibers and tail fibers, and handover of optical connectors, providing a basic guarantee for our online life. People's lives are increasingly inclined towards online shopping and information inquiry, and the network has become an indispensable part of our lives. The provision of the network comes from the support of various work equipment, and the fiber optic terminal box is one of them. In order to ensure our normal network life, we need to have zero problems with the fiber optic terminal box.
Firstly, the fiber optic cable terminal box itself has not been tested, and the optical path is either blocked or not chaotic, or the optical attenuation is too large; Secondly, front-end equipment malfunctions, such as cameras not having video or power on, etc;
Then check for faults in the backend equipment of the fiber optic cable terminal box, such as no video from the supervisor, audio from the phone, incorrect keyboard control protocol, and inability to control itself;
Finally, there is a fault in the connection line, such as the video header not being soldered properly, the control line being connected incorrectly, or the connecting lines being crossed or reversed.
The fixing device can be set outside or inside the casing, and a better solution is to connect it with the shell, so that external forces can be transmitted to the suspension parts of the casing, which is conducive to protecting the connection part from loosening or loosening. The fixing device should also consider the convenience of operation and be suitable for fixing components of self-supporting cable ropes.
Terminal box is suitable for the communication industry. It is a connecting device between small core optical cables and terminals, with the functions of fixing and fusing optical cables, and always connecting optical cables. The shell process adopts electrostatic spraying, which not only beautifies the appearance but also facilitates use. Internally equipped with fiber optic cable fixing devices, fusion splices, and cable loops. The fusion splicer adopts a stacked structure, with flexible configuration and a large capacity of up to 96 cores. When using a ribbon cable, it can reach 144 cores. It has the insulation function of optical cable technology components and terminal box shell, and is convenient for grounding.
The current terminal box technology is more flexible and can change specifications and sizes according to user needs. Process design mainly refers to the product forming scheme. Content is the main basis for design changes. Change material properties to cold treatment and material structure to heat treatment. The sheet metal shell adopts a unique EBD safety corner protector to avoid the risk of scratches. The product design is humanized, with high safety performance, high precision, and small deviation; Enable consumers to achieve 100% satisfaction.
The internet has gradually integrated into our lives, even in every corner. We also need to gradually understand some device knowledge related to the internet, among which terminal box installation is one of them.
Ground potential counterattack causes damage to fiber optic terminal boxes through the following forms: when lightning current leaks into the ground, the ground potential of the grounding grid will be raised to tens or hundreds of thousands of volts within a few microseconds. Power supply is the primary consideration for ensuring the reliability of video fiber optic terminal boxes. Due to the complex installation environment of fiber optic terminal boxes on site, some users usually suspect that the product has a fault first when debugging is not possible. In fact, the technology of fiber optic terminal box products is very mature, and they undergo repeated testing and copying before leaving the factory. Therefore, the possibility of problems with the product itself is relatively small. Therefore, when there are problems on site, the first thing to consider is installation issues.
You can investigate from the following aspects: firstly, the fiber itself has not been tested, the optical path is blocked or not chaotic, or the optical attenuation is too large; Secondly, front-end equipment malfunctions, such as cameras not having video or power on, etc; Then check for backend device malfunctions, such as no video from the supervisor, audio from the phone, incorrect keyboard control protocol, and inability to control itself; Connection line faults, such as incomplete soldering of video heads, incorrect connection of control lines, or incorrect or reversed connection of connecting lines. The fixing device can be set outside or inside the casing, and a better solution is to connect it with the shell, so that external forces can be transmitted to the suspension parts of the casing, which is conducive to protecting the connection part from loosening or loosening. The fixing device should also consider the convenience of operation and be suitable for fixing components of self-supporting cable ropes.
