ExtremeUSB technology based extenders for USB 3.0 are fiber based and certified with USB3 Vision cameras, thus offering systems integrators a reliable solution when vision applications need to be extended beyond 3 meters.

Extending USB 3.0 Over Fiber For Machine Vision Applications

Contributed by | Icron Technologies Corporation

USB (Universal Serial Bus) is undisputedly the most successful computer connection interface to date, with over ten billion USB devices already in the market and counting every day. But for machine vision applications, USB 2.0 has been only a minor player due to relatively low throughput rate (480 Mbps) and distance reach (5 meters) when compared to rival camera interfaces like FireWire, GigE Vision, and Camera Link.

A New Standard

Considerable excitement was generated when the AIA (Automated Imaging Association) announced it would be developing a new camera specification called USB3 Vision based on USB 3.0. Hot off the press (January 23, 2013), USB3 Vision cameras support  up to 5 Gbps of data throughput producing quality resolution, vibrant colours, and high frame rates comparable to Camera Link at a fraction of the total solution cost. USB3 Vision is well poised to become a dominant standard.

The only flaw with this good news story is USB’s weakness: distance limitation. Not all copper cables are capable of supporting USB 3.0’s higher bandwidth at any appreciable distance. And while great strides were made in improving throughput from USB 2.0’s 480 Mbps to USB 3.0’s 5 Gbps, distance took a step backward from 5 meters to 3 meters.

Bridging the Distance with Fiber

Fiber Optic cabling is the obvious choice over copper, especially with newer transmission standards such as OM3 multimode fiber. Fiber offers plenty of benefits:  the cable has a small diameter which allows for easy and convenient installation and great future-proofing by supporting increasing bandwidths. And while still carrying a premium over copper cables, fiber costs have come down over the past few years.

All the stars seem to be aligned with USB 3.0 and fiber to work together to resolve the distance gap. But it is never quite that easy.  Simply firing USB 3.0 data across fiber isn’t going to magically get high-definition vision cameras running at 100 meters from your control center.  That’s where ExtremeUSB® extension technology comes into play to complete the solution.

ExtremeUSB

ExtremeUSB® has long been the extension standard for USB 1.1 and 2.0, and is now bridging the gap for USB3 Vision. ExtremeUSB is a patented extension solution from Icron Technologies Corporation supporting plug and play functionality (no software drivers required) and compatibility with all operating systems including Windows, Mac OS, and Linux.

Icron’s USB 3.0 Spectra™ 3022 system meets the USB3 Vision specification and is able to extend USB3 Vision applications up to 100 meters over OM3 multimode fiber. Moreover, it is the first commercially available fiber extender to be certified by machine vision camera leaders like IDS, Lumenera, NET, Point Grey, and Ximea.

Additional Advantage with Fiber

Fiber not only facilitates throughput and distance, it also offers electrical isolation, which is a requirement for many critically sensitive medical and military applications, and can be manufactured to be flexible enough for tight locations or moving parts. 

Summary

USB 3.0 has arrived to the machine vision world as USB3 Vision and will start to increase its market share at the expense of other standards. Fiber is a very willing partner for cabling due to its ability to handle high traffic rates and noted easy installation attributes.  ExtremeUSB technology based extenders for USB 3.0 are fiber based and certified with USB3 Vision cameras, thus offering systems integrators a reliable solution when vision applications need to be extended beyond 3 meters.

PureLink - HCE III TX/RX: 4K HDR over HDBaseT Extension System w/ Control and Bi-Directional PoE

The HCE III Tx/Rx HDBaseT™ extension system offers full HDMI 2.0 compliance supporting HDR (High Dynamic Range) and 4K@60Hz with 4:4:4 chroma sampling. Featuring PureLink's proprietary Pr©cis codec, a light compression technology, the HCE III can transport Ultra HD/4K, multi-channel audio, and High Dynamic Range (10 bits support) content over a single CATx cable. The HCE III provides HDMI extension up to 130 feet (40 meters) at Ultra HD/4K and up to 230 ft. (70 meters) at 1080p over category cable with embedded multi-channel audio, CEC pass-through, bi-directional RS-232 and IR control, and PoE - all with zero loss and zero noise. The HCE III Tx/Rx also supports Dolby TrueHD, Dolby Digital Plus and DTS-HD Master Audio plus LCPM (up to 192 kHz). Additionally, the low profile "slim box" enclosure design make the HCE III ideal for limited space installation environments, such as behind flat panel displays and video walls.
