Q58: What are the indexes of products of 6 categories that we can't neglect?A58: Many key indexes of products have been neglected when the users choose the products. But it is very critical for the quality of the construction. Besides, it is also very helpful to improve the qualities of the cables wholly. 1. Which kind of value it is, the Typical Value or the Guaranteed Value? Generally speaking, the Typical Value is an affirmatory value which means it will be achieved even if the products are not good enough. In fact, the actual testing value must go over the lowest level but won't be lower than it. Judging from the definitions of the Typical Value and the Average Value, the actual testing value sometimes goes over the Typical Value and sometimes goes under it. But what the users are always concerned about is what the lowest value is on earth. Generally speaking, the Guaranteed Value is lower than the Typical Value at about 3-5dB. Therefore, it is wrong to compare the Guaranteed Value of products A with the Typical Value of product B. What the users should compare with is the Guaranteed Value of the two kinds of products, because the Guaranteed Value means that the actual performance of the two kinds of products will be much better than the lowest level. It is impossible that the actual performance is lower than the Guaranteed Value, so only the Guaranteed Value can make the users feel reassuring. A manufacturer who holds the credit standing should show the Guaranteed Value to the users, because it is a kind of promise. 2. Are both the Long Channel and the Short Channel suitable for the actual use? Most of us feel that the index of the Long Channel is better than the Short Channel, but actually the case is not like this. About some parameters, the Short Channel is not good as the Long Channel, because the indexes that many manufacturers give are based on the channel with the length of 100m. However, it cannot reflect the needs of users really. In fact, in most cases the lengths of the channels are between 30m and 40m. When the users buy the products, the two points below should be considered: 1. Does the manufacturer provide the users with the corresponding parameters? 2. Are both the Long Channel and the Short Channel suitable for the actual use? Only the products of six categories meet all the demands so that they can give the users the guarantee. Additionally, all the series of Addison products meet the demands that the newest test stipulates of the six categories Cabling System no matter what kind of channel is, the Long Channel or the Short Channel.. 3. The indexes of the performance are based on how many times are the products tested? Ten or thousands of times? If the indexes of the performance are just based on more than ten times of testing results (or even some manufacturers stipulate the indexes of the performance only by a certain test), such testing results can't represent the actual performance at all. Only the indexes of the six categories measure up the testing results for thousands of times so that the quality can be guaranteed. 4. Is it a whole frequency strip or a single frequency? Besides all the problems above, all the indexes should point to the lowest value of the whole frequency strip. If a manufacturer just provides the indexes of performance on a certain frequency, the users should consider whether it is safe to be used. Usually, these indexes the manufacturer provide with are the best in a given frequency. At least, the indexes in other frequencies are not as good as those in that given frequency. |
