Comprehensive analysis of the difference between cable and cables
- Sep 07, 2018 -

In the network hardware, there is a kind of can not be ignored is the network transmission media, we are often called cable.

At present, the more common network cable sub-twisted, fiber optic cable, coaxial cable and coarse coaxial cable. 1, Fiber optic cable: Fiber optic cable is a new generation of transmission media, and copper media compared to the fiber, whether in security, reliability or network performance has been greatly improved. In addition, the optical fiber transmission bandwidth greatly exceeds the copper cable, and its support maximum connection distance of more than two kilometers, is the establishment of large-scale network is the inevitable choice.

As the optical fiber and cable has good anti-electromagnetic interference, strong confidentiality, fast speed, large transmission capacity and so on, so its price is also more expensive, rarely used in home occasions. At present, there are two different types of optical fibers, namely single-mode fiber and multimode optical fiber (so-called "mode" refers to a certain angle into the optical fiber of a beam of light). Multimode fiber is generally used in the same office building or in a relatively close range of network connections. Single-mode fiber transmits data with higher quality and longer transmission distances, and is often used to connect office buildings or geographically dispersed networks. If the use of optical fiber and cable as a network transmission media, but also need to increase the optical transceiver and other equipment, so the cost of more investment, in general applications are less used.
