Usb 2 0 Cable Length Limit

The reason for these length limitations is that the electrical design of the usb model does not allow for cable lengths that are longer than 5 meters at the maximum.

Usb 2 0 cable length limit.

In other words you cannot just connect a bunch of extension cables together like taking a 6 foot cord and extending it with 4 other 6 foot extension cords and run them 30 feet to another room. Due to its design usb cable has a normal maximum length of about 5 meters 16 4 feet but you can get longer distances by using an active usb extension cable from monoprice. As you may already know the usb specification limits the length of a cable between high speed devices to 5 meters about 16 feet and for low speed devices the limit is 3 meters about 9 feet. 5 meters is also the maximum length for dvi a analog cables.

For maximum signal quality dvi cables will work up to 5 meters. Usb 2 0 provides for a maximum cable length of 5 meters 16 ft 5 in for devices running at high speed 480 mbit s. 5 meters is around 16 feet 5 inches and 3 meters is around 9 feet 10 inches. Among other improvements usb 3 0 adds the new transfer rate referred to as superspeed usb ss that can transfer data at up to 5 gbit s 625 mb s which is about 10 times faster than the usb 2 0 standard.

This is a bus powered extension cable that can be used to increase the length of a device without any signal loss or potential performance problems. For copper cabling with awg 26 wires the maximum practical length is 3 meters 9 ft 10. In the meantime applications such as machine vision pro av medical imaging etc. The usb 3 0 standard does not directly specify a maximum cable length requiring only that all cables meet an electrical specification.

The primary reason for this limit is the maximum allowed round trip delay. The 5 meter limit extends to dvi i integrated since it is capable of analog as well as digital. The length rules stipulate the length of the cable at 5 meters or 16 feet for usb 2 0 devices and 3 meters or 9 8 feet for usb 1 0 devices. Usb 2 0 3 0 3 1 cable maximum length limits according to usb if compliance specifications each type of usb cable length is limited as shown in table below.

Usb 3 0 is the third major version of the universal serial bus usb standard for interfacing computers and electronic devices. Any distance from 6 to 15 meters will result in lower signal quality but is available for dvi d digital cables. Constantly need cables that can go beyond usb if standard ranges.
