About the speed of the telecom FTTB LAN

The so-called FTTB is just an access mode, which means that the fiber to the building, the network cable to the home, the LAN mode is through the upper switch, so it is the sharing mode, the 2M you said is just your bandwidth is 2M, only it may be low, it cannot be high. That is to say, the theoretical peak is around 256kb when you are ** something.

In addition, I don't know if you are dial-up mode or static IP Internet access, if you are dial-up mode, it may be PON mode, if you are static IP, it may be pure LAN mode, but no matter which mode, the port of the upper-layer switch is divided into VLAN and port rate limiting. As far as technology is concerned, I personally feel that the PON pattern is relatively stable.

The upstairs is too professional, people may not understand, no one has been to the computer room, and no one knows what the port is. ADSL is a cable, a special line connected to the telecommunications room, FTT B is an optical cable, an optical cable, and then through the routing and other equipment to divide a lot, a channel, if too many people go at the same time, it will naturally be slow, so it will be slow during the evening rush hour, which is the disadvantage of optical fiber access. And ADSL, that is, you use a line by yourself, and during peak hours, it will not affect your Internet speed.

Summary: ADSL's advantage is stability, but the bandwidth is insufficient, the 8M line is already a bit difficult, the advantage of optical fiber is that the bandwidth is large, and the optical fiber can reach a 40-episode series that can be completed in a few seconds, I'm afraid that your hard disk can't withstand it.

FTTH is an optical cable into the home, and users can use **, broadband, IPTV and other services through a single optical fiber, but ONU equipment needs to be installed when installing.

FTTB is a fiber optic cable to the corridor or to the building, the ONU equipment is installed in a box somewhere in the building, and the user's installed machine is connected to the user's room through the five types of wires;

The biggest difference between the two is that FTTH can provide users with higher internet speeds.

Hello! Hopefully, the following will be helpful to you.

If both access methods are 8M broadband, then there is no difference in network speed! FTTB is fiber-to-the-building, network cable to the home. FTTH is fiber-to-the-home (you need to use optical modem), FTTH can access higher bandwidth, such as 100M or higher, FTTB cannot handle higher bandwidth due to network cable transmission bandwidth limitations.

The method of installing a wireless router is basically the same, there is no difference.

Connect the LAN port of the cat (FTTB fiber-to-the-building access mode, connected to the home network cable) to the WAN port of the wireless router, refer to the label address on the back of the router or the instructions for use, enter the router setting interface, start from the setup wizard, set up the router according to the prompts, select PPPOE dial-up for the connection mode, fill in the user name and password, and set the wireless network password (recommended letter + number combination) to save and restart.

Anhui Telecom's online business hall is carrying out the activity of "grabbing New Year's goods", and a variety of star machines have the lowest explosive price, dropping by 1,000 yuan! Large-screen smart phone discount**, apply for broadband and have a chance to get iPad mini!

If you still have questions, please keep asking. Have a great day, thank you!

Problem description: FTTB is access to the building, so it means that a building shares this bandwidth, that is, the more people, the less cost-effective, so that means that the higher the building, the more residents, the better? The 4-storey building and the 20-storey building are not the same ?..

Another question is whether the broadband speed is limited now? I just got blocked by wirecom, BT and other software, but I don't want to be filial piety and just change to other broadband and suffer the same thing.

Also, why do I think the popularity of ADSL is not high? People around me want to install 1m2m ADSL but almost no one can install it, it's all the problem of ** Qiaonian line aging and too far, so ADSL is a 512k mix? Is that okay?

Analysis: FTTB usually uses 25 to 30 port switches to convert fiber-to-the-network cable signals That is to say, whether it is a 4-story building and a 20-story building, it is almost the same, but there is only one switch on the 4th floor, and there may be 5 switches on the 20th floor, anyway, it is just 25 people sharing bandwidth Anyway, the more people use it, the slower it is

As for broadband. I'm using ADSL myself, and usually BT can go up to about 200k. Emule's words are hard to say.

In addition, if the ADSL line is too far, it can be installed by changing the number, that is, the line is moved from the remote computer room to the nearby computer room, usually the service is free, depending on the tariff of regional telecommunications But after the migration of the computer room, the ** number should be changed to the number segment of the new computer room, so the number should be changed

ADSL downlink up to 8m, uplink 640k, usually ADSL downlink telecom open 2m, up to 4m, uplink 512k, but it is exclusive Oh At least for the time being, I haven't seen the situation of sealing BT and being slowed down by more people Like Guangzhou, downlink 2m can be upgraded to 3m by signing an agreement, and the company's words can be up to 4m, and it is easy to drop the line if it is higher.

If your line is too far away, and Dou Song can't shorten the line to a nearby computer room, then you can only reduce the ADSL speed in exchange for stability.

FTTX+LAN broadband service is a broadband IP access service officially opened to the outside world by Taiyuan Communications. "FTTX+LAN" uses optical fiber + LAN access mode, that is, Ethernet is directly connected to the user end, and the user can access the broadband IP network at a speed of up to 100 megabytes through the LAN. The access of "FTTX+LAN" requires Category 5 cable integrated wiring, which is more suitable for various group users, such as:

**, enterprises, various data centers, schools, information community guessing groups, commercial office buildings, hotels, etc.

This is a broadband access scheme that uses optical friends to quietly add five types of network cables, realizing gigabit fiber to the center switch of the community (building), the central switch and the corridor switch are connected by 100 Gigabit optical fiber or five types of network cables, and the integrated wiring is used in the corridor, and the user Internet access rate can reach 10mbps, with strong network scalability and small investment scale. In addition, there are multiple access methods such as fiber-to-the-office, fiber-to-the-home, and fiber-to-the-desktop, which can meet the needs of different users. The FTTX+LAN mode uses a star network topology, and users share bandwidth.
