There are relevant specifications and standards for cable length when it comes to USB 2.0 and USB 3.0 standards:
USB 2.0 Standard:
In the USB 2.0 specification, it is recommended to use a maximum cable length of 5 meters without employing passive extenders or cables.
The specification states that if a longer cable length is required, active extenders or USB 2.0 signal boosters should be used.
USB 3.0 Standard:
In the USB 3.0 specification, the recommended maximum cable length is 3 meters without using passive extenders or cables.
The specification indicates that if a longer cable length is needed, active extenders or USB 3.0 signal boosters should be used.
It's important to note that these specifications and standards are developed based on considerations of safety and performance. Using cables longer than the recommended length could lead to issues such as signal distortion, reduced transmission speed, and device malfunctions. Therefore, when selecting cables, it's advisable to adhere to these specifications and standards as much as possible to ensure the proper functioning of the devices.
