What is the bandwidth of the general network cable?

The large transmission speed of ordinary household network cable is 100Mbps, which is about 12.5M, and the transmission speed of grade 6 network cable can reach 1000Mbps, which is about 125M m. ..

1 kbps = 1024 bps, 1Mbps= 1024kbps, which means that the bandwidth of 1Mbps is1024/8 =125 KB in download speed. Generally speaking, the theoretical download speed of broadband is equal to the bandwidth divided by 8. Due to the loss of broadband lines, there is usually a gap of about 20% between the actual download speed and the theoretical download speed.

Extended data

When designing the network, we should focus on the theoretical value of bandwidth, that is, the theoretical maximum number of data transmission bits under given conditions. The designed network speed should be equal to the speed allowed by the medium. When users use the network, they should consider the throughput, that is, whether the users are satisfied with the actually obtained bandwidth value.

An important factor that should be considered when building a network is the choice of media, which is related to the amount of files that users need to download. The larger the file, the more time it takes. Generally speaking, to enjoy online video smoothly, you need at least 300Kbps bandwidth. If it is a high-quality movie, the bandwidth requirement is higher. So 10M bandwidth is enough.
