The difference of Optical cable, twisted pair and coaxial cable

author:kingsignal time:2017/08/17

In the network hardware, there is a class can not be ignored is the network transmission media, and we usually called the network cable. At present the more common network cable twisted pair, fiber optic cable, coaxial cable and coaxial cable and so on.

As the optical fiber optical cable with anti-electromagnetic interference is good, confidentiality, fast, large transmission capacity, etc., so its price is more expensive, rarely used in the home. Currently more common there are two different types of fiber, respectively, single-mode fiber and multi-mode fiber.

 

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 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.

 

2.Twisted pair

 

Twisted pair cable is a flexible communication 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 5 Stranded wire.

 

3. Coaxial cable 

 

coaxial cable is a lot of friends are familiar with a class of transmission media, it is a layer of insulated wire wrapped around the central copper conductor cable, its biggest feature is the anti-interference ability, transmission data stability , And the price is cheap, so it was widely used, such as closed-circuit television lines.

 

However, before the coaxial cable used more, mainly because the coaxial cable composed of bus structure network cost is low, but a single cable damage may lead to the entire network paralysis, maintenance is also difficult, this is its biggest drawbacks. The coaxial cable in Ethernet applications is mainly divided into coarse coaxial cable and thin coaxial cable.

 

The above is a brief description of fiber optic cable, twisted pair, cable distinction, learn more about the contents of the optical cable, please pay attention to kingsignal official website.
