What is the difference between telecom fiber and broadband? How to measure the speed of telecom fiber broadband?

Home broadband generally uses ordinary network cables and optical fibers. Each broadband requires a "fiber modem" or "ordinary modem" to receive the broadband signal of the main line. What is the difference between telecom optical fiber and broadband? For us, it has always been difficult to distinguish them clearly. Today, we will share and introduce them in detail one by one, hoping to make it clear!

What is the difference between telecom fiber and broadband?

Telecommunications optical fiber is to convert the data to be transmitted from electrical signals to optical signals for communication. "Optical modems" are installed at both ends of the optical fiber for signal conversion. Telecommunications optical fiber is the most ideal transmission medium among various transmission media in broadband networks. Its characteristics are large transmission capacity, good transmission quality, low loss, long relay distance, etc. Optical fiber transmission uses wavelength division multiplexing, that is, the data of multiple users in the community are modulated into optical signals of different wavelengths and transmitted in one optical fiber.

The difference between telecommunication fiber optic and ordinary broadband access methods is that ordinary broadband uses electrical signal transmission, while fiber optic broadband uses optical signal transmission.

How to test the broadband speed of telecom fiber optic?

1. Before testing the speed, if you are using a router, please disconnect the router and directly connect the computer's network cable to the fiber optic modem.

2. Go directly to the official website of China Telecom and click on broadband fiber in the middle of the webpage.

3. Click in, scroll to the bottom of the webpage, and click on broadband speed test.

4. Click Smart Speed ​​​​Up in the pop-up window.

5. Click Self-service speed test.

6. After entering the speed test interface, click to start speed test and wait for the system to automatically test the speed. After the speed test is completed, the broadband speed will be displayed. Please close all programs on the computer during the speed test to avoid affecting the accuracy of the speed test.

What do I need to buy to get broadband?

1. Home broadband generally uses ordinary network cables and optical fibers. Broadband application requires real-name registration, and registering identity information is the first step.

2. Secondly, each broadband requires a "fiber optic cat" or "ordinary cat" to receive the broadband signal of the main line. When applying for it, the business hall will ask you to purchase a designated "cat".

3. If you need to access the Internet or use wireless network on your mobile phone, you need to buy a wireless router and connect it to the "cat". Then you can create a virtual WiFi signal for your mobile devices to use.

How to set up China Telecom broadband DNS

Steps for setting up the DNS for Telecom Broadband:

1. Right-click on My Network Places and click Properties.

2. Find the local connection in the network connection. Generally, a computer will only have one local connection. Right-click the local connection and left-click Properties.

3. In the pop-up Local Area Connection Properties window, double-click Internet Protocol;

4. Add numbers on the page that appears, add the DNS server address and click OK. Because the DNS server address is different in each region, you can consult the local telecommunications business hall or telecommunications customer service for the specific server address.

How to solve the problem of abnormal account of China Telecom broadband?

1. Check the network cable interface, power supply and network equipment to ensure that the network cable interface is firm and not loose, and the power supply and network equipment are stable.

2. When restarting the router or broadband modem, it is recommended to turn off the power and wait for 3 to 5 minutes before turning it on again. It is also recommended to set the redial time interval after the router is disconnected to 5 minutes to prevent the router from dialing too fast.

3. When dialing a number using a computer, the time interval between two dialings should be at least 5 minutes.

4. Prevent multiple computers in the LAN from dialing with one account.
