What is the impact of the uplink and downlink of the fiber on the network speed

Optical fiber broadband converts the data to be transmitted from electrical signals to optical signals for communication. At both ends of the optical fiber, there are "optical modems" for signal conversion.

Optical fiber is the most ideal one of a variety of transmission media in broadband network, which is characterized by large transmission capacity, transmission capacity, low loss, long relay distance, etc. Optical fiber transmission uses wavelength division multiplexing, that is, the data of multiple users in the cell is fused into high-speed signals using PON technology, and then modulated to different wavelengths of optical signals are transmitted in an optical fiber.

The difference between optical fiber broadband and ADSL access mode is that ADSL is electrical signal propagation, and optical fiber broadband is optical signal propagation.

Broadband is a newly installed telecom 8m optical fiber,The downlink can reach up to 1m s,The uplink can be up to 500k s,At the same time, it's a tragedy,I opened the browser to upload in Youku at full speed 500kb upload,Then open Thunder** software,**Speed runs to 1m,Upload plummets,Only 100k is less,Dozens of kb run。 Doesn't it mean that the optical fiber is uplink and downlink and does not affect each other, the optical modem is ZTE ZXHN F612, the router is Netgear 614 V7, and the tomato is brushed, and the computer is a PCI-E 300M wireless network card equipped with a desktop.

1. The uplink speed is the speed at which you upload, such as when you send an email, upload, etc., and the downlink speed is mainly the speed of your upload, such as when you watch a movie, something, etc., usually we say a few m, all refer to the downlink speed. Generally, the uplink of ADSL is only 512K, regardless of whether the downlink is 2m or 4m.

2. The downlink is determined according to the size of the bandwidth, and the uplink is generally about the same. What operators call a few meters of broadband and ** speed are two different concepts. For example, the speed of 1m is 1024k, and the unit here is bytes, that is to say, the speed of 1m is equal to the byte of 1024k.

The operator's broadband of several mbits, the unit is bits, that is, 10m broadband actually refers to 10m bits, which are also 10*1024k bits. One byte is equal to eight bits. To change the operator's broadband to ** speed, you need to divide the broadband by 8.

3. The bandwidth of broadband is not equal, and the speed of household optical fiber generally refers to the speed of the first class. To put it simply, uplink means that you upload data from your computer to the network, for example, if you send an email and have an attachment, the speed of that upload is uplink. The downlink is easy to understand, and if you open a web page from a network ** file or a web page, it is all downlink.

It's all fiber optic now, and the adsl replied upstairs is the previous story, and it's not accurate.

4. According to telecommunications, the downlink rate is one-eighth of the uplink. For example, the 100m household optical fiber of general telecommunications now, the uplink speed is, of course, this m number is not the actual speed, it can be simply divided by 10, which is the actual speed, that is to say, 100m optical fiber, theoretically your ** speed can reach 10m per second, and the upload is only.

The broadband uplink speed is mainly the speed of uploading, that is, the speed of sending data from the computer to the Internet, such as sending emails, uploading**, etc.;

Usually when we say a few meters, we all refer to the downward speed. Regardless of whether the downlink speed is 2m or 4m, the uplink speed of ADSL is only 512K;

Normally, the downlink speed is large and the uplink speed is large.

The money spent is different.,Now it's basically downlinked.,General company fixed IP.,Uplink and downlink are equal.,Conventional household,4M,Downlink 4M,Uplink Now 100M's broadband uplink can reach up to 20M,Normal is 4M.Or 10m

Quite simply, the upside is gold and the downside is scrap metal.
