Why don t you use an optical fiber connection between your router and your computer, but a normal ne

Hello everyone, I'm Daming, optical fiber is not directly connected to the computer and router, this question is still quite interesting, so I will talk about it in detail, why optical fiber can not be directly connected to the computer? <>

Reasons why optical fiber cannot be directly connected to computers and routersRegarding this question, I would like to start by talking about what is optical fiber? What is a Router? The optical fiber is the signal source of the broadband fiber, that is, the thin line that is connected to the signal source port of the optical modem, and it is this line that provides the broadband optical fiber signal to the optical modem.

The function of the router is to share the Internet, when the optical fiber signal is connected to the optical modem, and then the LAN port of the optical modem is directly connected to the WAN port of the router with a network cable, the router can be shared after setting, and finally connected to the computer network card by the router, it is such a working program.

What the questioner said is to directly connect the signal of the optical modem to the router and the computer, which is obviously not right, and the existence of the optical modem cannot be ignored! The computer is connected to the Internet through a router or a direct optical modem LAN port. <>

SummaryThis Q&A explains why the fiber optic signal can not be directly connected to the computer and router, my point of view is that as long as you understand the basic principles of broadband Internet access, everything will be solved, note: the computer is not absolutely not directly connected to the optical fiber, the premise is that it needs to be equipped with a "fiber optic network card", but the price of the optical fiber network card is relatively much higher, if it is for home use, Daming recommends that you still use an ordinary network card to meet everyone's daily Internet speed.

The above is the content shared today,I hope it will be helpful to you,If you like it, don't forget to like and follow,Daming will continue to create works on computer maintenance and applications,If you have different views on such issues,You can discuss it together in the comment area,Open the "app"Search for "Computer Technician Daming", a large number of original computer knowledge, for your reference, this issue of Q&A is here, let's see you next time!

Since fiber optics are so fast, why don't you use ordinary network cables instead of fiber optics between the router and the computer?

Because the networking cost is too high, the later maintenance is too complicated. The reason why optical fiber networking is difficult to popularize is mainly because the cost of composition is too high, home networking needs to use optical fiber, routers are replaced with routers with optical interfaces, and computers also need to purchase gigabit or 10 gigabit network cards that support optical fiber interfaces. The router that supports the optical port is about 2500, and the gigabit network card that supports the optical port on the computer is about 500 yuan.

The first problem is that the ** of pure optical routers and computer optical cards is still high.

The second problem is actually to a large extent the current integrated wiring, whether it is an individual or a decoration company is very familiar with optical fiber networking.

The third problem is the daily maintenance problem, that is, the optical fiber is still relatively fragile.

Because fiber optic connections are too expensive, there is no need for ordinary residents to use them, and it is good to use ordinary network cables.

Broadband is required for a dial-up connection to access the Internet.

1) Open the Network & Sharing Center — set up a new connection and network;

2) Connect to the Internet — Next;

(3) Broadband (PPPoE)(R) — Enter the username and password, click Connect to connect normally.

How to set up Internet access for direct connection to the computer? The cat needs to be set up to go directly to the Internet, and it is not possible to access the Internet if it is restricted, and it is necessary to enter the broadband password given by the operator to access the Internet.

Here's how:

Mori Shen shed 2Go to the home page of the terminal and enter your password to log in.

3.Once you're logged in, select "Network" on the home page, and then go to the network settings page.

4.Click on the broadband settings in "Broadband Configuration". You can see that the initial settings bar is grayed out and cannot be set.

5.Right-click in the blank space, select Review Element, and then click Open Console.

Search for "mode" to find the corresponding ****, and the corresponding ** line to find the networking mode modifier frm mode: Modify "disabled" to "abled" so that the networking mode can be modified.

7.Mode: Modify to bridge mode, save and exit.

8.In the bottom right corner of the desktop, tap the network icon and open the network settings.

9.Select Dial.

10.Click Set up a new connection, then select Connect to the Internet, and finally click Next.

11.Select Set up a new connection.

12.Select Broadband (PPPoE)(R) and continue.

13.Fill in the broadband and password provided by the carrier, and check "Allow others to use this connection" according to your personal needs. Finally click on Connect.

14.When the connection is successful, the newly created broadband connection is displayed. This rule.
