Regarding fiber optic Internet access, what equipment is required for fiber optic Internet access

Under normal circumstances, it can be about 10 times faster! Of course, it also depends on the speed limit of ** line and fiber Internet access by the telecommunications bureau in your area!

The initial installation fee is ......I only have Unicom here to install fiber! And there are more than 100 households in the community to sign up, and there is no initial installation fee! Others, such as telecommunications and Netcom, are not safe at all!

A simple definition of optical fiber.

Fiber optics are a medium that transmits information from one end to the other. It is a piece of glass or plastic fiber that acts as a transmission medium for the passage of information. _

Usually the terms "optical fiber" and "fiber optic cable" are confused. Most optical fibers must be covered by several layers of protective structure before use, and the covered cable is called a fiber optic cable

Characteristics of optical fibers.

Since optical fiber is a transmission medium, it can transmit data such as calls or computer data like ordinary copper cables, but the difference is that optical fiber transmits optical signals instead of telecommunication signals. As a result, fiber optics have a lot of unique advantages.

For example: broadband bandwidth. Low loss. Shielding from electromagnetic radiation. Lightweight. Security. Privacy.

Introduction to optical fiber + Ethernet optical fiber access business.

At present, there are three main ways of broadband access: Ethernet access, ADSL access and cablemodem access. Among them, ADSL and Cablemodem are both using the current copper wire resources, so the resource advantage of Internet access in the old residential areas and buildings is realized. However, in the broadband access of new residential areas, buildings, units and Internet cafes, the Ethernet access mode is significantly superior to other Internet access due to its high bandwidth and stable performance and future development applications.

At present, China Unicom Xiaogan Branch provides Internet broadband access for Internet cafes, residential areas and office buildings, which is based on high broadband optical fiber and stable incoming, and realizes user Internet broadband access through the best access method of broadband access in the world --- Ethernet broadband access. This broadband access method is collectively referred to as "optical fiber + Ethernet broadband access".

Fiber + Ethernet fiber access features.

1) Users do not need to spend a lot of money to buy broadband access terminal products, but only need a very cheap network card (market price of 50-100 yuan) to install Internet broadband.

2) Internet broadband is not limited by transmission lines, and the bandwidth can range from 64k to 1000 megabytes or even higher, which is difficult to achieve by other broadband access methods.

3) Internet access is not divided into upload and ** rate, but adopts exactly the same communication rate, which is completely parallel. The biggest advantage of using parallel rates is to play online games and other applications that require fast upload and ** speed.

4) The use of "optical fiber + Ethernet broadband access is flexible and diverse, and you can use ** server sharing access, switch direct access, etc.

5)"Optical fiber + Ethernet broadband access" line is stable, for users, the maintenance workload is small, and the operation is simple.

6) Advanced technology, easy to upgrade, no need for the second investment.

It's too expensive, unless it's the entire access of the cell.

Fiber optic Internet access requires equipment: splitbox, media converter, router, computer.

How to connect the WAN port of the router to the router: Connect the WAN port of the router to the LAN port of the media converter with a network cable, and when the WAN port light of the router flashes, the connection is normal.

How to configure a wireless router:

3. Set the Internet access mode: Enter the WAN port in the advanced settings to set up the annual search. If the broadband service needs to be dialed, please select PPPoe dialing, PPPOE dialing needs to enter the broadband rock password, and the connection mode is automatically connected according to the date calendar;

4. Set the WiFi name and password: Enter the wireless security in the wireless settings, and select WPA2-PSK mode for the security mode. Select AES for WPA encryption rule.

Set up a wireless network key. The router will automatically restart after setting, please enter a new wifi password to connect.

1. The optical fiber itself cannot access the Internet, so it is necessary to use the equipment of the optical fiber operator's computer room, and the user side uses optical modem. Only when an operator activates broadband services can an optical modem access the Internet through optical fibers.

2. For broadband processing, you can go to Unicom or Telecom business hall to handle broadband business with your ID card and other relevant valid documents. Different places, go to the local operator's business hall to understand the difference between single-installed broadband and broadband, and choose the way that suits you. After handling the business, go home and wait for the installer to come to install.

3. It is best to use the modem provided by the operator, as the modem you buy may not be compatible with the operator's equipment in the computer room and cannot be used.

4. When installing broadband, pay attention to the length of the network cable should not be too long, and the longest should not exceed 100 meters.

5. Each room in the home needs to be connected to the Internet, and it is necessary to deploy network cables in each room to concentrate on the location of the home optical fiber, and connect the branch network cables to each room through the router.

**It's 10 trillion in about 800 a month, and the speed can be much faster, but the speed of opening the web page is average.

There is no need for home use, ** is too high, ADSL is already able to meet.

A lot of foreigners still use 56k dial-up Internet now.

You can choose Netcom or Telecom. Fiber optic cables need to be routed directly to your home.

That is, in front of your station, the signal used is an optical signal, and the medium of transmission is not cable, but optical fiber.

Optical fiber is a medium in which quartz glass is made of 125 microns (about the same thickness as a hair) and a core (about 10 microns) is used to transmit optical signals. The core of the optical fiber is doped with germanium, and the refractive index is higher than that of the glass outside the core, so the optical signal can be fully reflected inside the core and can be transmitted over long distances.

In addition, fiber optics have a large enough bandwidth and are the ultimate choice for broadband networks.

Equipment needs: optical fiber is generally a pair, there must be photoelectric conversion equipment, as well as a router, generally when installing optical fiber to access the Internet, a fixed IP number will be given, and then set through the entry of the route (note: different routers, the method of setting is not the same), after the router is set, it can be directly connected to the switch, or a stand-alone connection.

To explain it to you in the most earthy analogy, OK

Your friend said that the use of fiber optics in Hong Kong, indeed, Hong Kong has the fastest penetration of fiber optics, and they use FTTH, which means fiber to the home!

Slow internet speed in China? adsl

It depends on how many MBs

The higher the number, the faster it is!

Whether the use of fiber is fast or not depends on the egress bandwidth set in the data center.

Optical fiber transmission capacity is large and fast, this is for sure.

However, if the speed limit of telecom ISP and other operators is only 1MB, then even if you use optical fiber, it can only reach 128kbp s in theory, so you should know that whether optical fiber is fast or not does not depend on the type of line!

Tell you a technical knowledge.

Actually, ADSL is also from optical fiber, and this is not me talking nonsense.

Let me tell you. If you think about it, ADSL is now popular all over the country, and it is popular in cities and villages, and ADSL uses optical fiber transmission on the uplink module.

I don't know if you understand?

The province to the city is optical fiber, the city to the county (district) is the optical fiber, and the county to the town is the optical fiber.

Therefore, the long-distance transmission of the first network, the broadband network are all optical fiber lines, just to the local, the installation of the first copper wire, generally more than 6km away, can not open ADSL when the line transfer box is directly used, in the use of modules, optical fiber, and then become a copper wire to connect a few kilometers of broadband or ** users!

If you want optical fiber, you need an optical module converter, a router, and then a power adapter (that is, an ordinary network cable RJ-45 interface).

The speed depends on how much bandwidth the telecom company gives you, ** can also be consulted.
