Why is my 4M fiber upload speed only 60k s? 20

It's normal. The upward and downward transmission of home optical fiber is asymmetrical, because in the operator's computer room, the home optical fiber is still connected to the equipment of ordinary broadband-ADSL. Ordinary broadband upload bandwidth only, no matter how much ** is, the upload is.

Broadband below 10m, there is almost no difference between optical fiber and copper wire: optical and electrical are 300,000 kilometers per second, but the attenuation of light is reduced, and optical fiber is only about 3% higher than copper wire, but it is much more expensive and extremely cost-effective.

If the copper wire is expanded to more than 10m, it is more difficult, and the distance that can be transmitted is very short, so it makes sense to use optical fiber.

The table is entangled, and it is enough for one person to have a home. Not to mention your home, many companies are pulling ordinary broadband, and twenty or thirty people still use that upload bandwidth.

If you want to upload bandwidth exceeded, then use optical fiber dedicated line, I won't explain the principle, its performance is the same up and down network speed, ** is dozens of times that of ordinary broadband, 4m, Unicom is about 2400 yuan or so.

1. Whether you use the wireless network, the bandwidth may be occupied.

The actual bandwidth of MB is only more than 500KB, understand, it may also be caused by server-side congestion, but it is unlikely.

400m fiber.

Theoretically, the speed is 47mb s is 400m fiber. The upload speed of 400M fiber is the same as the ** speed, both are 50MB. However, due to problems such as node lines, it is impossible to reach 50MB, but it will not be much worse.

400m fiber refers to the speed of the network.

Speed: Speed refers to byte s. When the software is in the software, it is common to see the words such as the speed display as 128kbps (kb s), 103kbs and other broadband rate sizes, which refers to (byte seconds), that is, bps.

Optical fiber: The use of optical fiber to connect the network has the characteristics of fast transmission speed and reduced attenuation. "10M" refers to 10240kbit s (i.e. 10M) converted to **speed: mb s

In the real world. The theoretical value is up to mb s. Excluding network loss and line attenuation, the real ** speed may be less than mb s, but as long as it is about 1mb s, it is normal.

400M fiber refers to a network speed of 400Mbps, and the actual ** file shows the unit is "B". "b" and "bps.""is an eightfold relationship, i.e. 400mbps 8 = 50mb

It's almost 380m, but there are some things when you pass Thunderbolt and so on, if you have resources in your local LAN, the speed will increase a lot, that is to say, if you are the LAN seed reason, the real speed may be about 5m!

I don't know if this theory applies to fiber optics.

By analogy, it should be 500 megabytes of bandwidth.

Broadband bandwidth = **speed * 8 The fastest **speed measured bandwidth is inaccurate, generally with a web page directly **about 200 megabytes of files, the record will be ** completed when the speed is multiplied by 8

More than 50m, and your company has no speed limit, and your speed depends mainly on your ** site, your site is not speed limit, you will get off fast, if the other party has a speed limit of 1m, your 100m fiber is useless!

, so the fastest bandwidth is 381M

The theoretical value, excluding the line attenuation and loss, is generally normal.

It depends on how many computers you have connected. If you're a single computer, then the speed of 10m fiber is 10m seconds.

The theoretical values are normal between them.

1. The uplink and downlink bandwidth of the optical fiber are the same (if the operator does not have restrictions).

The uplink and downlink bandwidth of megafiber broadband is 8 Mbit/s.

1mbps=1024kbps

12mbps=12288kbps

Through unit conversion, the result is obtained: the uplink and downlink bandwidth of 8 megabyte fiber broadband is 12288kbps.

3. The actual network is affected by various factors such as distance and interface. In fact, the network bandwidth is lower than the theoretical value.

4. At present, some local operators limit the uplink rate of ordinary household users, resulting in the uplink rate being much lower than the uplink rate, and the uplink and downlink asymmetry is mainly due to commercial considerations

First, it is to save costs (large throughput and more equipment).

The second is to distinguish home users from government and enterprise private line broadband users (the monthly cost is 1,000 yuan, which is far more expensive than home users).

Equipped with broadband, Internet room! Guangdong Telecom's online business hall is equipped with telecom broadband, faster, easier and more economical! 4M pure telecom broadband, no fixed line and mobile phone, one household and one line, no peak pressure on network speed, please click for details.

Your situation is normal. The up and down speeds are not equivalent.

Telecom home broadband uploads are rate-limited.

400m fiber refers to the speed of the network.

is 400Mbps, and the actual unit displayed in the Fiber Load file is "B". "b" and "bps.""is an eightfold relationship, i.e. 400mbps 8 = 50mb

400m fiber refers to the network speed of 400Mbps, and the actual ** file display unit is "B". "b" and "bps.""is an eightfold relationship, i.e. 400mbps 8 = 50mb

If it helps you, hope.

First of all, if you are 20m fiber broadband theoretical speed should be reached, the actual use is affected by factors such as the line, it is normal to reach 2m s, but the speed is only 400k s, which is obviously abnormal.

There is also a situation that after installing a wireless router, if it is a single computer to access the Internet, the network speed is basically the same, if it is multiple computers to access the Internet at the same time, your network speed will be slower. Telecom will limit the speed of the Internet. You can set a fixed IP, so that the speed will be better.

Internet speed generally refers to the length of time it takes to request and return data when a computer or mobile phone is surfing the Internet, uploading and ** data. To improve the (computer) network speed, it depends on the ISP (network service provider) access network situation, generally divided into three kinds, ADSL access, FTTB-LAN access, FTTH access, generally without changing the network access mode, improve the network bandwidth, and will not directly improve the network speed, in other words, the same 4 trillion network bandwidth, ADSL access network speed in China is basically divided into 50m s, 100m s, the other less.

20M broadband is 2560KB s 1024KB=, therefore, the theoretical speed of 20M broadband is, that is, theoretically, 1 second can be about the content of about 1 second.

Reason: 2. Hardware limitations, such as networks, routers and other accessories can only support a maximum of 4M network.

Repair method: 1. It is recommended that the user use a special broadband speed test software to check the network speed, if the bandwidth cannot be reached by the user, it means that it is a broadband problem, and you can directly call the operator's customer service to report for repair.
