Is broadband a network cable? What's the difference between broadband, network cable and optical fiber?

As we all know, you need to use two things when surfing the Internet, one is network cable and the other is broadband. For a computer boy, it is difficult to distinguish these two things, and it is easy to regard them as a whole, which leads to many jokes. So, is broadband a network cable? Here's a detailed introduction: Is broadband a network cable? What's the difference between broadband and network cable and optical fiber? I hope I can give you some help and inspiration!

Is broadband a network cable?

Is broadband a network cable? In fact, they are different because broadband is a dynamic definition and there is no strict division. Network cable is a communication transmission line and an indispensable transmission cable in LAN connection, which can be divided into twisted pair, coaxial cable and optical cable. Therefore, before using it, you must understand it clearly, so as not to make a joke, which is not worth the loss.

What's the difference between broadband, network cable and optical fiber?

First, the network cable

First of all, introduce the network cable. Network cable is an essential communication connection device in LAN connection, which is divided into twisted pair, coaxial cable and optical cable. Among them, twisted pair is a data transmission line composed of many insulated intersecting lines. For example, the common telephone line in our life is twisted pair, which needs a crystal connector to connect it.

Second, optical fiber.

Secondly, introduce optical fiber. In fact, optical fiber is what we often say. It is a kind of fiber synthesized by light on glass or plastic, which uses the radiation function of plastic to conduct light energy. Generally speaking, the optical fiber will be wrapped in a plastic sheath so that it can be bent without breaking. When a pulse is detected by a light emitting diode or a laser beam, a transmitting device at one end of an optical fiber is transmitted to a receiving device at the other end.

Third, broadband.

Finally, we will introduce broadband, which is a dynamic concept. There is no fixed standard. When spreading various media on the Internet, as a necessary communication technology, it can meet people's sensory needs.

What types of broadband are there?

1、DSL

DSL technology is a broadband access technology based on telephone line.

2. Cable modem

Cable modem cable modem, we call it a cat.

3、ISDN

It can provide voice, data, images, text and other services on telephone lines, so it is also called "single-wire communication". It is not only advanced in technology, but also has many services, but it is more expensive.

Summary: The knowledge about whether broadband is a network cable, and what is the difference between broadband, network cable and optical fiber is introduced here. In fact, network cable and broadband are not the same concept, and their functions and uses are different. Therefore, when using them, you should read them carefully and not be careless.
