How long usb cable can be

There are two ways of doing this. First, you could use an active extension cable, sometimes called a repeater cable. Second, you could use a powered USB hub.

So, which one of these methods is going to be the most effective for your network? Active extension cables are similar to ordinary extension cables with one important difference.

They have electronics inside that boost the signal in your USB cable. This allows you to extend the cable significantly further than its rated length. Because these cables need to be powered, they typically require an external power adapter. A simple USB power supply can get the job done.

USB 2. This assumes that the initial cable is an active cable. The maximum length of USB 3. The initial cable also affects your length in another way. Your extension cables can only be as long as the original cable. However, they can also be used to extend the range of your wired connection. This comes with a caveat.

The USB hub must be powered. Just like active extension cables, USB hubs come with some limitations. First off, the overall maximum length is the same.

With a non-powered initial cable, the overall maximum length of a USB 2. Similarly, USB 3. The same rule also applies for initial cable length. Subsequent cables in the series can be shorter, but not longer than the original. The USB standard only allows you to connect 7 tiers of device. You just cannot move the turntable any closer.

Well, all is not lost. These, in essence, repeat the transmission they receive and send it on to the other device. Please note that the cable on either end of the repeater cannot exceed 5 meters.

So, you can extend the cable out to 10 meters 32 feet, 10 inches. But you need to go even farther, so you just keep adding cables and hubs. Hold on there, there are limits. The absolute maximum number of powered hubs you can use is 5, but it could get a bit kludgy using that many hubs. USB 2. Shop USB 2. Shop USB 3. No attempt is made to boost or regenerate the signal so passive cables are susceptible to the problems of attenuation and noise described above.

However, buying a good quality cable with thicker gauge copper conductors and better shielding will allow you to modestly extend signal transmission beyond the recommended maximum distance. Consider an Active USB Cable Active cables include circuitry, usually at the receiving end, that regenerates the signal and enables data to be transmitted over longer distances.

Active cables can be daisy-chained so long as power is available for each transceiver in the chain. Most USB extenders can transmit data up to feet without signal loss. These extenders are an ideal choice for a wide variety of USB devices, including printers, scanners, hard drives, audio devices, touch screens, and Web cams that require long distances from your laptop or PC.
