Usb 2 0 cable length limit.

It is recommended that manufacturers distinguish usb 3 0. 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 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. Constantly need cables that can go beyond usb if standard ranges.

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. 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. Any distance from 6 to 15 meters will result in lower signal quality but is available for dvi d digital cables.

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. The 5 meter limit extends to dvi i integrated since it is capable of analog as well as digital. 5 meters is around 16 feet 5 inches and 3 meters is around 9 feet 10 inches. 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.

In the meantime applications such as machine vision pro av medical imaging etc. The 2 0 specification limits the length of a cable between usb 2 0 devices full speed or hi speed to 5 meters or about 16 feet and 5 inches. For copper cabling with awg 26 wires the maximum practical length is 3 meters 9 ft 10. 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.

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. 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. For maximum signal quality dvi cables will work up to 5 meters.
