What about China Telecom s 4M broadband?

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

Integration of 159 yuan**, the network hall handles free 4m liters 8m, and gives 160 yuan per month to share the phone bill (three mobile phones and one fixed phone sharing fee), handle it now, save the broadband fee to send the mobile phone, send itv (free **).

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

Hello: Telecom four-megabit broadband is very good, the theoretical speed can reach 512kb per second, if you want to handle broadband, you can go to the telecom network hall, now the network hall also has preferential activities, win a romantic trip to France, telecom broadband new users, you can get 2 free cinema movie vouchers (used in Guangdong Province). Draw a buffet coupon for two, and ** trip to Provence, France.!

The theoretical speed of 4M telecom broadband is 512kb per second.

The speed is a little slow. Here are a few things you can check:

1.If there is a router, it is recommended to perform a stand-alone test to see if the network speed is normal, if it is, it is a router problem.

2.It is possible that the computer is poisoned and the computer is running slowly, and the computer can be checked and killed.

3.Whether any network interfaces are loose.

4.None of the above can solve your problem, and it is recommended to call 10000 for repair.

The quality of telecommunications is not said.

Then Netcom can also be used. Actually, I don't eat much, as long as I don't play games.

Dear Telecom users, Hello!

According to your description, the most obvious difference is that the transmission medium is different, one is the first line virtual dial transmission is an analog signal, the other is the optical fiber transmission is an optical signal, which is more stable than the first line broadband.

The second difference is that the bandwidth that can be achieved is not the same, optical fiber, as long as you pay for it, you can apply for the bandwidth of G, and it is impossible to achieve such bandwidth with ** line.

The third difference is that the cost is of course not the same.

The equipment used in the two is naturally completely different, ordinary broadband is mainly ** line and moden, broadband is either optical cable machine + protocol converter, or optical modem.

Hope it helps.

If you need to buy a machine, you can go to Anhui Telecom Tianyi store (hundreds of mobile phones are low on the whole network.

As long as your ADSL works stably, theoretically there will be no difference, relatively speaking, the maximum speed of the light brazing will be higher and more stable, but because it is limited to 4m, there is not much difference, and the cost is only more than 150 higher than the current one, which is a bit unreasonable.

The fiber precipice is fast!

For example, in the next 3G game, fiber will take a few minutes, and broadband may take hours.

Optical fiber and broadband both transmit signals, the difference is that optical fiber is a digital optical signal, and broadband is an electrical signal.

Optical fiber is the abbreviation of optical fiber. Optical fiber communication is a communication mode that uses light waves as the carrier frequency and optical fibers as the transmission medium.

Advantages of Fiber Optics:

1. Large transmission frequency bandwidth and communication capacity.

The optical carrier frequency is 5x1014 MHz, and the bandwidth of the fiber is several gigahertz or even higher.

2 Low signal loss.

At present, the practical optical fibers are made of quartz (SiO2) material with high purity, and the attenuation can be reduced to near the theoretical limit when the optical wavelength is around 1550nm. As a result, its relay distance can be very far.

3. Immune to electromagnetic interference.

Because the optical fiber is a non-metallic dielectric material, it is not subject to interference from electromagnetic waves.

4. Thin wire diameter and light weight.

Since the diameter of the optical fiber is very small, only left and right, the diameter of the fiber optic cable is thinner than that of the cable, and the weight is also lighter.

5.The network latency is within 10 ms for optical migration access, and within 50 ms for ** line access. 、

Taken together, fiber optic Internet access can be faster, with lower loss, longer use, and lower network latency than broadband.
