In the network hardware, there is a class can not be ignored is the network transmission medium, we often referred to the network cable. Currently more common Subdivisional twisted pair cable, Fiber Optic Cable, coaxial cable and coaxial cable and other crude.
1. fiber optic cable: fiber optic cable is a new generation of transmission medium, the medium compared with copper, fiber, whether in security, reliability or network performance has greatly improved. In addition, the optical fiber transmission bandwidth well beyond copper cable, and maximum connection distance it supports up to two kilometers, is the formation of large-scale network of inevitable choice. Since the optical fiber cable has good resistance to electromagnetic interference, confidentiality, speed, large transmission capacity, etc., so its price is also more expensive, rarely used in household applications. Currently, there are two common types of optical fiber, which are single-mode fiber and multimode fiber (so-called "model" refers to a certain angle of the beam of light into the fiber). Multimode fiber is commonly used for network connections to the same building or a relatively close distance of the region. Single-mode fiber and a higher quality of data transmitted, the transmission distance is longer, is typically used to connect between the office network or wider geographically dispersed. If you use a fiber optic cable as the network transmission medium, the need to increase the light end of the transceiver and other equipment, so the cost of investment in larger applications in general less used.
2. Twisted Pair: Twisted Pair is a flexible communications cable contains a pair of insulated copper wire, which is characterized by cheap, they were widely used, such as our common telephone lines. Depending on the maximum transmission rate, twisted pair can be divided into three categories, Category 5 and 5e categories. Rate category 3 twisted pair is 10mb / s, 5 classes of up to 100mb / s, while the ultra-5 class and up to 155mb / s or more, and can be adapted to the needs of future multimedia data transmission, it is recommended to use Category 5 or Category 5 double stranding. Twisted pair shielded twisted-pair can be divided into (stp) and unshielded twisted pair (utp). Although the rate is low stp twisted pair (only 4mb / s), but strong anti-interference ratio utp twisted pair, so the price should be a lot more expensive, and now a few dollars cheaper UTP such a meter, expensive thing possible more than a dozen yuan to buy one meter. In contrast, utp twisted pair price is generally about one meter a dollar, relatively low. In addition, the commonly used 10m and 100m unshielded twisted pair is the popular name for 10base-t and 100base-t, we often see in the market. And supporting the use of twisted-pair also rj45 crystal head for the joint production of twisted pair LAN rj45 interfaces between its quality is directly related to the stability of the entire network can not be ignored.
3. Coax: Coaxial cable is more familiar to many of my friends for a class of transmission medium, which is composed of layers of insulated wire wrapped around the central copper conductor cable, its greatest feature is a good anti-jamming capability, the transmission data stable, and the price is cheap, so once widely used, such as cable TV lines. However, before the coaxial cable used more, mainly because of lower bus structure of the network coaxial cable costs, but damage to a single cable may cause paralysis of the entire network, it is difficult to maintain, which is its biggest drawbacks. Coaxial Ethernet applications are divided into thick coaxial cable (10base5) and thin coaxial cable (10base2) two kinds. Now a thick coaxial cable used much, and thin coaxial cable is also some markets. Thin coaxial cable is generally the market price of a few dollars one meter, not too expensive. In addition, the coaxial cable is used and connected to the bnc head, sold on the market are generally coaxial cable and bnc connector has been well finished, we can be directly used.
