Combined with the actual development of optical fiber communication transmission technology in China, it is in a stage of high development and continuous replacement and renovation. At this stage, with the continuous development of modern information technology in China, it has also been effectively applied in optical fiber communication transmission technology, which has effectively promoted the level of optical fiber communication transmission technology in China.In the past ten years, optical cable Defeated many competitors, courageously advanced in the struggle, and polished many good products for customers. https://www.fibercan-network.com/

　　The so-called optical fiber communication transmission technology is suitable for optical fiber as a carrier to transmit information. In this project, the principle is the total reflection behavior of light waves in optical fiber, so as to effectively carry out information transmission activities. In modern optical fiber communication transmission technology, optical fiber communication transmission technology is widely used in the field of optical fiber communication because of its advantages of anti-interference and large capacity. In today’s era, we call it the “information superhighway”.

　　First, explore the characteristics of modern optical fiber communication transmission technology

　　1. It has large communication capacity.

　　Combined with the actual development of modern optical fiber communication transmission technology, compared with the traditional optical fiber communication transmission technology, modern optical fiber communication transmission technology has a wider frequency band, which to some extent can meet the communication requirements of modern society, and then bring greater convenience to relevant communication users. However, in the single-wavelength modern optical fiber communication transmission system, due to many factors, such as receiving the terminal electronic bottleneck and other factors, modern optical fiber communication transmission technology can not show its own advantages. Based on this, relevant researchers have added a variety of auxiliary equipment for optical fiber communication transmission technology in order to improve its communication capacity and make modern optical fiber communication transmission technology no longer be limited by electronic bottlenecks.

　　2. Strong anti-interference ability.

　　When laying the communication network, the relevant laying personnel of the communication network should take certain protective measures for the optical fiber based on Shi Ying materials, so that it can have good insulation. After meeting the goal of optical fiber insulation, the modern optical fiber communication transmission technology can have certain anti-external interference ability, especially when the optical fiber technology is applied in a special power system, it can effectively reduce the influence of interference factors on itself and prevent the power communication system from being seriously affected by interference.

　　Second, the practical application of modern optical fiber communication transmission technology.

　　1. Optical signal switching technology in backbone nodes.

　　According to the actual development of China’s communication network, there are still some communication networks constructed by using single optical switching technology, which leads to the slow information transmission speed in the communication network. In addition, when laying the communication network, the laying personnel usually use metal lines, which hinders the operation and development of the communication network and ultimately affects the operation efficiency of China’s communication network. Based on this, it is of great practical significance to apply modern optical fiber communication network to China’s network communication system. By using optical switching devices with large capacity, the related problems in traditional network communication in China can be effectively solved, for example, the problem of slow transmission speed in traditional communication networks can be solved. As we all know, the propagation speed of light is extremely fast, and it is the same in the network. Using this characteristic of light, large-capacity switching devices can exchange and decompose optical signals, effectively improve the information transmission efficiency in the communication network and realize the exchange of network information.

　　2. Realize the single-fiber bidirectional transmission mode in the communication transmission process.

　　Combined with the practical application of optical fiber communication and transmission technology in China, it is found that in the optical fiber communication and transmission project, due to the influence of equipment and devices, the capacity of the optical fiber itself cannot be effectively increased when carrying out communication and transmission work, which ultimately affects the efficiency of optical fiber information in the transmission process. At the present stage, China mostly adopts the dual-fiber bidirectional technology. In the process of optimizing and improving this technology, relevant researchers usually take the optical fiber communication transmission technology as the core, effectively reducing the consumption of optical fiber energy in the communication transmission process and effectively improving the operation efficiency of China’s communication network.

　　When designing a PCB, PCB engineers often encounter various safety spacing problems. Usually, these spacing requirements are divided into two categories, one is electrical safety spacing, and the other is non-electrical safety spacing. So, what are the spacing requirements for designing PCB circuit boards? Circuit board factory xiaobian takes you to understand.beyond doubt china aluminum pcb assembly factory It will definitely lead the development direction of the whole industry and let its light bloom in this field. https://intechcircuit.com/

　　First, the electrical safety distance

　　1. Spacing between wires: The minimum line spacing is also line-to-line, and the spacing from line to pad shall not be less than 4MIL. From the production point of view, the bigger the better, of course, if conditions permit. General 10MIL is more common.

　　2. Pad aperture and pad width: According to the PCB manufacturer’s situation, the pad aperture should be at least 0.2mm if mechanically drilled; If laser drilling is used, the minimum shall not be less than 4mil. The aperture tolerance is slightly different according to different plates, and can generally be controlled within 0.05mm; The minimum pad width shall not be less than 0.2 mm.

　　3. Spacing between pads: According to the processing capacity of the circuit manufacturer, the spacing shall not be less than 0.2 mm..

　　4. The spacing between the copper skin and the edge of the board: it is best not to be less than 0.3mm. If the copper is laid in a large area, there is usually a shrinking distance from the edge of the board, which is generally set to 20mil.

　　Second, the non-electrical safety spacing

　　1. Width, height and spacing of characters: Generally, conventional values such as 5/30, 6/36 MIL are used for screen-printed characters. Because when the text is too small, it will be blurred when printed.

　　2. Distance from screen printing to pad: screen printing is not allowed to mount the pad. Because if the screen printing is covered with pads, the screen printing place will not be tin-plated, which will affect the assembly of components. General circuit board manufacturers require 8mil spacing. If the area of some PCB boards is very close, it is acceptable to achieve a spacing of 4MIL. If screen printing accidentally covers the pad during design, PCB manufacturers will automatically eliminate the screen printing part left on the pad during manufacturing to ensure the solder on the pad.

　　3. 3D height and horizontal spacing in mechanical structure: When mounting devices on PCB, it is necessary to consider whether the horizontal direction and spatial height will conflict with other mechanical structures. Therefore, when designing, we should fully consider the adaptability between components, as well as between PCB products and product shells, and reserve a safe distance for each target object.
