Usb3 Vision Cable Length

Passive cables have a maximum length of 4 5 meters where active and hybrid cables have a maximum length of 20 meters but the two latter are way more expensive and not supported by get cameras.

Usb3 vision cable length.

The usb 3 interface supports a gross bandwidth of 5000 mbit s however the draft of version 3 1 announced a bandwidth of 10000 mbit s. The standard is currently in version 1 0. While icron will brand the cable as the usb 3 0 spectra 3001 15 cei will offer the product as the bit maxx extreme usb 3 0 figure 1. Usb 3 0 is also completely plug and play ready.

In order for usb 3 0 to thrive as a viable camera interface in machine vision applications the cable length limitation must be overcome. According to the usb 2 0 standard the maximum length of a usb 2 0 cable is 5 m. However the biggest limitation to the length of the cable is the quality of the cable. Constantly need cables that can go beyond usb if standard ranges.

Usb3 vision cable length regarding the length of the cable it is of importance that the cable has been fully examined for compatibility with usb3 vision. The 3 0 3 1 specification does not specify a maximum cable length between usb 3 0 3 1 devices superspeed or superspeed but there is a recommended length of 3 meters or about 9 feet and 10 inches. The usb3 vision interface is based on the standard usb 3 0 interface and uses usb 3 0 ports that will soon be standard on most pcs with windows 7 service pack and windows 8 native support expected soon. In the meantime applications such as machine vision pro av medical imaging etc.

Thanks to its real time compatibility and high bandwidth usb 3 0 is poised in the medium term to replace two old slower interfaces on the vision market firewire and usb 2 0. According to usb if compliance specifications each type of usb cable length is limited as shown in table below. Longer cables can be used if they are made of high quality material and where transmission distances are longer hubs or active repeaters can be installed. Cable length of 3 5 m using consumer cables is supported 8 m is possible with good cables.

This white paper examines why the usb 3 0 cable limitation is problematic and explores the different options to extend usb 3 0 considering the pros and cons of the respective extension solutions. There are several other advantages. In the machine vision industry more often than not distance becomes the first obstacle anyone experiences during the camera set up. To address the machine vision market icron has now teamed with components express inc to develop a usb3 vision compliant 15m usb 3 0 active extension cable.

The usb 3 0 interface has recently been renamed usb 3 1 gen 1. Components from different manufacturers will easily communicate with each other.
