As you probably know, all common USB cables have a certain maximum length for better performance, and if they exceed this range, the overall performance will suffer. But if we want to increase the length of the USB cable, what can we do? At first, USB cables were very short in length, and therefore the issue of size limitation was not raised for them. But with the development of this field, this standard has been used for many more tasks. As a result, some users have to use longer USB cables.
However, for example, cables based on the USB 2.0 standard can have a maximum length of 5 meters, and the maximum length of USB 4 cables is only 0.8 meters. Is. Fortunately, by using some methods without losing the signal strength, we are able to increase the length of the USB cable, which we will discuss below. /strong>
Extension cables also known as USB extenders are considered the most common method for this work. These types of cables use male and female ports, so you can easily connect the current cable to it. In the field of USB extenders, we deal with 3 types of passive, active and optical, which we must choose according to the needs.
Passive extenders have a common copper wire and do not have a special electronic circuit to amplify the signal. . Therefore, these types of cables are not suitable for increasing the cable length beyond the permissible limit. On the other hand, active extenders have electronic circuits to amplify the signal. As a result, they can significantly increase the overall length of the USB cable. Also, some active USB extenders can also be connected in a chain to increase their length. Of course, there are many limitations in this field.
Unlike passive and active extenders, optical extenders with cables They are fiber optic and therefore use light to transmit data. Light transmits data significantly faster than electricity and is less subject to signal degradation. So when you need to extend the length of the USB cable by several meters, optical extenders are very useful. But unfortunately, optical extenders have a high price.
USB to Ethernetconversion>
Ethernet cables, which are known as network cables in Iran, are used for data transmission with High speeds are great over long distances, so you can use this technology to extend the length of your USB cable. By using USB to Ethernet conversion, you can increase the length of the cable up to 100 meters. In this context, you can use single or multiple port conversion. Single-port conversions usually do not need a power source, but for multi-port conversions you need an adapter.
USBhub with a power source strong>
Like active extenders, powered hubs can be used to extend the length of a USB cable. We should note that according to the facilities provided by the USB standard, users can connect up to 5 hubs with energy sources.
