A communication Cable Assembly is a Wire Harness used to transmit signals. A communication cable consists of a plurality of mutually insulated wires or conductors to form a cable core, with a communication line with a sealing sheath on the outside. Some are also equipped with an outer sheath outside the sheath. There are various laying methods such as overhead, direct burial, pipeline and underwater. According to the structure, it is divided into symmetrical, coaxial and integrated cables; according to functions, it is divided into field and permanent cables (underground and submarine cables). The communication cable has a wider transmission frequency band, a larger communication capacity, and less external interference, but it is not easy to repair. It can transmit phone calls, telegrams, data and images, etc.
Communication cable assembly can be classified mainly by cable types and applications

In June, the fans’ four-year match with the World Cup will finally be honored. It will take less than 20 days to reach the World Cup. Because of work and life reasons, they will not be able to visit friends in Russia. I guess that every time you When the World Cup will have such a feeling of regret, then the choice of friends at home and watch the game, how to get the closest visual perception of the scene it? Let's take a look at each of you today. What qualities a TV should have is best suited for watching sports events. 
In addition to simple rough dimensions, what else should we pay attention to? With a wide range of TV attributes, what are the real additions to the competition?
MEMC: motion picture compensation technology, we believe that everyone has encountered this situation, television in the presentation of high-speed motion picture, there will be smears, pictures, jitter and other situations, some of the display technology known friends may also know that this It is a physical defect of liquid crystal display technology, and it is also a drawback caused by the difference between the output signal and the input signal refresh rate. It is an almost inevitable problem. We can only use software algorithms to try to weaken it to the extent that the naked eye can not be differentiated.
The so-called MEMC, is a kind of motion picture quality compensation technology used in LCD TVs. The principle is to use a dynamic video system, insert a frame of motion compensation between the traditional two-frame image, the ordinary flat-panel TV 50/60Hz will be the screen refresh rate gain, thus eliminating the screen smear and other drawbacks to bring the discomfort Feelings, this function is very necessary for watching sports events. At the same time, it is also a significant boost for action movies. 
OLED: Extremely transparent picture In 2018, the entire television industry finally returned to the right path - back to the era of "picture quality is king". As a strong competitor for the next-generation display technology, with the continuous expansion of the global OLED camp, OLED TVs have fully erupted in this year's market, demonstrating unprecedented vitality. 
Smart TV/box information can focus on smart TV information network sofa butler (http://), China's influential TV box and smart TV website, providing information, communication, TV boxes, smart TVs, smart TV software, etc. Answering questions.
According to the type of cable, communication cables are classified as follows:
1. Single-conductor: refers to the most primitive communication cable, a single-conductor loop, with the earth as the regression line.
2. Symmetrical cable: a loop composed of two identical conductors under ideal conditions.
3. Coaxial cable: The inner and outer conductors on the same axis form a loop, the outer conductor surrounds the inner conductor, and the two are insulated at the same time.
Then they are classified according to the application as follows:
1. Long-distance cable: The transmission distance is long, and it is generally multiplexed. Most of them are directly buried in the ground. In a few cases, they are installed overhead or installed in pipelines.
2. Cables in the city: the wires in the cable are "paired and paired", and the number of pairs is large. Generally installed in the pipeline, a small number of urban cables are attached to the building or installed overhead.
3. Office cable: mainly refers to the communication cable used in the telecommunications office, generally installed on the distribution frame, and some are installed in the wiring trough; the office cable is used between the transmission equipment and the switching equipment in the telecommunications office, and other Inside of intra-office equipment. In order to prevent fire inside the telecommunication bureau, it is sometimes necessary to add a flame retardant sheath to the bureau cable.
What TV is best suited to watching the Focus Cup?
What kind of TV is best for watching football? Now the 55-inch TV seems to the author, at best, it is a starting size. Because of the gradual rise of LCD panels and the highly mature technology yield, the product prices are gradually dropping. Now, 65 inches is the true trend size. TV is the home appliance with the highest service life in the home.
Big enough is king, 55-inch TV is a bit out of date!
Combining the market research in recent years, the average size of TVs selected by consumers in China is increasing at a rate of 2-3 inches per year. Some people say that 55-inch TV products are the main tone in 2017, but the time will come in 2018. Did you say that? Large screen TV brings unparalleled visual impact
The most important thing is that the TV is even more capable of giving us a stronger sense of presence. This is the same with the purpose of curved TVs that many manufacturers have advertised. However, the simple and rough size increase gives us a sense of visual shock. The most direct. 55 inches is still the mainstream of the market, but of course we need to do is not followers of the mainstream market, but also to do the trend of leading the tide! Starting from a 65-inch product is a more appropriate choice. MEMC can effectively eliminate smears
This year is the sports year. Many manufacturers are developing product research and development for the events. Some televisions even come with sports models. Simply put, when users watch World Cup matches, the TV can automatically recognize and switch sports modes. For example, Hisense Automatic Sports Mode technology automatically optimizes the brightness of the sports signal to present a realistic lighting environment that is close to the event. This makes the game more realistic and its presence is naturally stronger. Hisense U7 comes with sports mode
The second major feature of the automatic sports mode technology is the intelligent recognition and enhancement of high-frequency colors such as red, green, and blue on the court, real reproduction of the color details of the stadium, and more user-friendly eyeballs. Finally, the automatic sports mode technology can also accurately extract and optimize the trajectory of the football, ensuring that each goal line is clearly visible. High-end OLED TVs are also suitable for viewing
Compared with LCD TVs, OLEDs are more suitable for watching sports events. The correspondingly high speed of electroluminescence allows OLEDs to have a natural display capability superior to that of liquid crystals. This kind of self-luminous material TV can bring deeper understanding. The black field performance is due to the advantage of independent light emission of each pixel of the OLED. Of course, the OLED TV also has a higher contrast ratio and the screen is more transparent. Sony A8F OLED TV
OLED products in the category of "come in people's hearts" brand is of course a joint venture brand headed by Sony, OLED TV is still positioned high-end crowd, the price is still relatively expensive, to Sony's new 65A8F this year, the price of 25,999 yuan is also true Many people are discouraged, but if you buy it, you will be surprised by the OLED display. This type of product is very suitable for consumers who have high requirements for visual effects.
