The theoretical download speed of 10M fiber broadband is 1280KB/s, but the actual download speed is much lower than the theoretical value, and the actual speed is much lower than the theoretical speed. It is caused by the influence of multiple factors such as line attenuation and signal attenuation.

The calculation formula of the download speed of the bandwidth: Theoretical download speed (unit KB/s) = bandwidth (unit M) × 1024÷8.

So the theoretical download speed of 10M broadband: 10×1024÷8=1280KB/s.

Network bandwidth refers to the maximum bit data that can pass through in unit time (1 second). Just like the lanes of a highway, the greater the bandwidth, the more lanes. Network bandwidth is an important indicator to measure network usage. It is not only an important basis for the government or unit to formulate network communication development strategies, but also one of the main factors for Internet users and units to choose Internet access service providers.
