The Use Of Different Data Cables To Protect The Value And Use Of The Field
- Oct 27, 2017 -

If we are just outside the words of the people, I do not know how much we understand the Data Cable, the two years we have the speed of the fly to improve the general, because there is a Data Cable, we have been secured, because there is a Data Cable, That we can at home, there are network Data Cable. Do you know what's the difference between the three products?

1. fiber optic Data Cable

Fiber optic Data Cable is a new generation of transmission media, compared with the copper medium, whether it is in the security, reliability or network performance has been greatly improved. In addition, the fiber transmission bandwidth is much higher than the copper Data Cable, and its support for the maximum connection distance of more than two kilometers, is the formation of a larger network of the inevitable choice. As the fiber optic Data Cable with anti-electromagnetic interference is good, confidentiality, fast, high transmission capacity, etc., so its price is more expensive, rarely used in the home. At present, there are two different types of fiber, respectively, single-mode fiber and multi-mode fiber (the so-called "mold" refers to a certain angle into the fiber a beam of light). Multimode fibers are typically used for network connections within the same office building or in areas of relatively close proximity. The single-mode fiber transfer data is of higher quality, longer transmission distance, and is often used to connect between buildings or geographically dispersed networks. If you use fiber optic Data Cable as a network transmission medium, you need to increase the optical transceiver and other devices, so the cost of investment in the general application of less used.

Twisted pair

Twisted pair Data Cable is a flexible communication Data Cable that contains a pair of insulated copper wires, which are characterized by inexpensive, so are widely used, such as our common telephone lines. According to the maximum transmission rate, twisted pair can be divided into three categories, five categories and five categories. 3 types of twisted pair rate of 10mb / s, 5 categories up to 100mb / s, while the super 5 class is up to 155mb / s or more, can be suitable for future multimedia data transmission needs, it is recommended to use Category 5 or even over 5 Stranded wire. Twisted pair can also be divided into shielded twisted pair (stp) and unshielded twisted pair (utp). stp twisted pair although the rate is low (only 4mb / s), but the anti-interference than utp twisted pair strong, so the price should be much more expensive, and now this twisted pair of dollars a few dollars, More than ten dollars to buy one meter. In contrast, utp twisted pair price is generally about one meter a meter, relatively low. In addition, the commonly used 10m and 100m unshielded twisted pair popular call is 10base-t and 100base-t, we can often see in the market. And twisted pair supporting the use of rj45 crystal head, for the production of twisted pair and network card rj45 interface between the joints, its quality is directly related to the stability of the entire network can not be ignored.

3. Coaxial Data Cable

Coaxial Data Cable is a lot of friends are more familiar with a class of transmission media, it is a layer of insulated wire wrapped around the central copper conductor Data Cable, its biggest feature is the anti-interference ability, transmission data is stable, and the price is cheap , So was widely used, such as closed-circuit television lines. However, before the coaxial Data Cable used more, mainly because the coaxial Data Cable composed of bus structure network cost is low, but a single Data Cable damage may lead to the entire network paralysis, maintenance is also difficult, this is its biggest drawbacks. Coaxial Data Cables in Ethernet applications are mainly divided into coarse coaxial Data Cable (10base5) and thin coaxial Data Cable (10base2) two. Coarse Data Cable is now almost used, thin coaxial Data Cable and some markets. Fine coaxial Data Cable market price of a few dollars a meter, not too expensive In addition, the coaxial Data Cable is used and bnc head connected to the market to sell coaxial Data Cable lines are generally and bnc head connected to the finished product, we can directly use.
