The more inconspicuous the consumables, the easier it is to fake
The network cable is the most inconspicuous of many network consumables. Although network faults are common, but few have heard of any problems with the network cable, so there are few eye-catching network brands in the market. Recently, some readers have called to ask questions about why the price gap between the market and the Internet is so huge. After the reporter’s unannounced visit to the market, I found that the current network cable market is mixed, and the fake goods in the market are rampant. So what is the status of the cable market? How to correctly distinguish the authentic network cable? We focus on the identity war of true and false network cable.
The network cable market is chaotic
Recently, readers and friends called to ask, "How many kinds of amps are there in the market? How much should a real price be in a box?" When I started receiving this consultation call, the reporter did not intend to, and thought that the market would be free to turn around. Can answer the reader's question. However, when the reporter visited the consumables market in Block B and the basement of Bainaohui, it was discovered that the various complicated network cables in the market were more confusing, not to mention the price, and even the name was extremely easy to confuse.
Just visit a counter that sells wire. Just ask if there is an Amp network cable. The other party must answer “Yesâ€. If you continue to ask the other party how much it costs, the seller will usually ask you, “From more than 100 to expensive. Yes, what do you want?"
A brand will come out a few prices?! Sellers often vowed to explain, "Not a brand, you see this cheap is the Amp Star, that is Amp Unicom ...", slightly turned around the market It is possible to collect various counterfeit brands such as Amp Beat, Ampson, Amp Star, Amp Unicom, etc. The price is between 190 yuan and 350 yuan per box.
In fact, although the above brands are numerous, they basically only belong to a confused name. In the process of unannounced visits, when the reporter asked about the place of origin, the sellers reported that they were produced in Ningbo, Zhejiang or Guangzhou, and explained that this belongs to Domestic brands.
The price of the real AMP cable is very expensive. The market price of each box should be up and down at 700 yuan. The quality of the Amp network cable is excellent, and the price is high. It is the most counterfeit product on the market. In the current market, IBM and Dingzhi are also brands that are prone to counterfeiting and counterfeiting in many network cables. At present, the price of high-quality domestic network cable is not cheap. For example, the current price of TCL cable has been as high as 540 yuan, but compared with international brands, counterfeit and counterfeit products of domestic brands are much less. From this point of view, buying fakes of domestic brands The probability is basically zero.
Everything is first
Why is the network of counterfeit Ampo so many? Xiao Liu, an engineer who has been engaged in network cabling for many years, gave a detailed account of the sale and purchase. "Profit determines everything, and the brand of Amp is sold too well. For example, we sometimes give customers wiring, customers are not at all. Understand the engineering requirements and design, but he will specify the brand of the network cable, face box and other products, and even go to buy it in order to reduce the cost, but such a customer, he can not buy the real Amp, now the demand market of the fake Amp Very big, because there are too many people who don't understand the quality of the cable to blindly pursue the brand."
Xiao Liu further explained, "I have been engaged in network cabling for 10 years. There are very few quality problems in the network cable. I have never heard of such things as folding or data transmission. The poor quality of the network cable will lead to signal loss. And the most direct impact on the transmission performance of the local area network, some companies and Internet cafes did not pay attention to this problem at the time of installation. Later, when the transmission traffic continues to increase, there will be a slow network speed, intermittent phenomenon, serious It can also cause network outages."
During the unannounced visit, the reporter also found that when the counter seller recommended the cable products, he always asked "What do you use?" When the reporter said that he wanted to connect to the laptop, the other party would not emphasize the product quality. If the company indicates that the company's network cabling or transmission distance is more than 40 meters, the seller often recommends a network cable with a price of more than 300 yuan, and repeatedly emphasizes that only such products can ensure the stability of the network.
At present, the characteristics of counterfeit products are generally low, but the number of meters per box is insufficient, the standard is 305 meters per box, and the messy counterfeit brands can generally use up to 200 meters. In addition to the length, the cable diameter is also one of the key points of shrinking. The standard cable has a wire diameter of 0.5. Many low-cost cables on the market have a diameter of 0.45 or even 0.4. In contrast, the video can be clearly visualized. The difference between the thickness of the two lines.
According to engineer Xiao Liu, in fact, the chaos in the network cable market is mainly caused by two reasons. The first reason is that the brand and test of the cable market is not as prominent as other product markets, and the consumption problem is not concentrated, so it is not easy to attract everyone's attention. The second reason is that because the network cable market has huge profits, although the products are inconspicuous, the net profit of the network cable market is often higher than that of large digital and even notebook computers. On the one hand, it has high profits, on the other hand, it lacks industry standards, and the chaos in the network cable market is hard to avoid.
Distinguish high-quality network cable
Although the network cable market is mixed, there are still some simple ways to judge the quality of the network cable. Generally speaking, the real brand manufacturer will mark its own anti-counterfeiting mark on the outer skin, which can be judged by distinguishing the thermal sensitivity of the cable mark and part of the laser mark. This method is suitable for respectively high quality and inferior network cable, for no The identified network cable is not recommended for purchase.
In addition, the outer rubber of the high-quality network cable has flame retardancy, and the fake mesh cable does not have, so the combustion is a very good test method. Just like buying a pure wool sweater, the cable is ignited. After burning, the high-quality cable will only have a sparking star in the outer skin, and the cable will not be open fire but only cracked. If the flame jumps brightly after a large fire, the product can be considered as a defective fake.
High-quality twisted pairs need to use copper wire as the core, which feels heavy and bends freely. Inferior network cable In order to reduce the product, usually other metal elements are added to the copper core, the resulting line is relatively hard, and it is easy to disconnect during installation and use. Since the copper core is relatively soft, it can be bent arbitrarily. Therefore, after the network cable is firmly gripped, the high-quality network cable will slowly spring up to restore the shape, and the inferior network cable is often difficult to bend. Judging whether the network cable is mixed with iron, a small piece of copper core can be peeled off, and then adsorbed by a magnetic screwdriver. The adsorbed product is inferior in quality, which easily causes cable resistance mismatch, which shortens the transmission distance and reduces the transmission speed. Among them, the regular Category 5 twisted pair will be marked with a printed sample on the line. The font is clear for laser printing and will not be smeared with oil. The line should be printed with the words “24AWG, CAT5†to indicate the standard and diameter of the copper core. Diameter, and CAT5 is the meaning of Category 5 line.
Postscript: The network cable is the basis of the network background. If the copper wire of the network cable is of high purity, the communication quality signal will be better, and the transmission distance is far. For example, the genuine Amp Super Category 5 line can support up to 120 meters in the maximum single-segment length, and ensure that the transmission speed reaches 1000Mbps. It is very likely that the fake network cable will have a signal attenuation that cannot be used normally at 20 meters. Its electromagnetic noise and no Balance is also much better than genuine. Therefore, here we must remind the consumers that when buying the network cable, don't be confused by the price and type of the famous network cable, and don't blindly pursue the brand and be smashed by the fake goods, because of the price of the network cable products of various brands sold in the market. Different, the quality is also uneven, consumers should not only buy cheaper products, but buy products with unqualified products. When purchasing the network cable, use patience and caution to discern carefully, and finally purchase quality products with reliable quality.
