CoaXPress-over-Fiber: Gaining momentum with camera maker adoption
In an effort to extend the benefits of CoaXPress to applications where traditional copper coaxial cables are reaching a ceiling in terms of speed, total bandwidth, weight and distance, Euresys is now promoting the new CoaXPress-over-Fiber Bridge protocol. Originally developed by Euresys / Sensor to Image, CoaXPress-over-Fiber is the result of the cooperation between the members of the CoaXPress Workgroup. The new standard has now been formally adopted and published by the Japan Industrial Imaging Association (JIIA) as a further enhancement to the widely adopted CoaXPress interface standard, allowing for broad industry adoption.
To greatly speed time-to-market for new products based on CoaXPress-over-Fiber from camera makers, frame grabber manufacturers and embedded vision system developers, Euresys
has released a new series of IP Cores for either device/transmitter or host/receiver devices looking to fully implement the interface and underlying complete protocol. Euresys
has also already released the first frame grabber to implement CoaXPress-over-Fiber
with the addition of the new Coaxlink QSFP+
to its already widely used Coaxlink series
of frame grabbers.
This has allowed several camera manufacturers to become early adopters of the new fiber-based protocol. Out of several companies developing new cameras based on CoaXPress-over-Fiber
, some have already been open about their forthcoming new product releases planned for this year.
The first, Vision Research (USA)
has already in late 2020 publicly demonstrated a prototype of their new ultra-high-speed camera series. This new model is capable of acquiring images at full 4K resolution at nearly 1,000 frames per second (fps), and by narrowing down the Region of Interest (ROI), it can achieve frame rates in excess of 500,000 fps using just two QSFP+ connections.
According to Lee Denaro
, a Senior Test Engineer who serves as Systems Engineer for the Vision Research
S991 CoaXPress-over-Fiber project, "Partnering with Euresys
/ Sensor to Image
to become an early adopter of this new extension to the CoaXPress standard has been an excellent experience for us. Not only did we adapt our next generation machine vision camera designs to use the Euresys
/Sensor to Image
CoaXPress IP Core, we also were able to relatively quickly implement the new CoaXPress-over-Fiber
) using their new CXPoF Bridge IP Core
. This, combined with the active technical support of Euresys
, allowed us to promote this new approach for broad industry adoption with the standards committees. Using their new Coaxlink QSFP+ CXPoF
frame grabber and eGrabber
software, we were able to realize a dual QSFP+ implementation perfectly matching our high performance machine vision cameras. Rather than requiring the use of 16 coax cables to carry the full bandwidth of our sensors to the host PC, this can now be done with just 2, much lighter and longer, fiber optic cables without the need for any additional hardware. Streamlined implementation and improved operational performance combined."

Another camera maker
, CIS Corporation (Japan)
has recently seen a prototype of their new 4K/240 fps QSFP+ camera design validated. This camera is also capable of higher frame rates by specifying a smaller Region of Interest (ROI) and will be the first in a growing offering of CoaXPress-over-Fiber
"We have been using fiber optics to connect machine vision cameras to frame grabbers in Japan for many years. We are now happy to support the newly released CoaXPress-over-Fiber
international standard by developing compatible cameras", says Yusuke Muraoka
, President, CIS Corp

Other manufacturers as well are jumping on the bandwagon
line of CoaXPress cameras is very successful and we see CoaXPress-over-Fiber
as a way to move forward, opening up opportunities for even higher resolution and higher speed cameras", says Ryan Kyung
, Sales Team Leader at Vieworks,

As early adopters of the CoaXPress interface, IO Industries (Canada)
cameras and video recording systems gained praises from customers across many application areas for their cabling reliability and simplicity. We also identified many applications calling for longer cable length and increased speed, without compromising the reliable point-to-point connection, deterministic timing and high throughput offered by CoaXPress. Adopting the CoaXPress-over-Fiber
protocol with a single QSFP+ optical interface for our Redwood camera family, supporting 45MP and 65MP CMOS sensors, is for IO Industries
a timely, state of the art, response to our most up to date customers”, says Andrew Searle
, Sales Manager at IO Industries

In the coming months, we are sure to see several more camera makers announcing new models based on the CoaXPress-over-Fiber
extension of the CoaXPress standard, which will see rapid adoption by the industry as a very high-performance interface over light weight and commonly available fiber optic cables and transceivers coming from the network environment. These widely available cables and components mean a much more cost-effective, reliable and non-proprietary fiber infrastructure for years to come.
“Through drafting and actively contributing to the CoaXPress-over-Fiber
vision standard, Euresys
confirms its role as a CoaXPress leader. We are happy to bring to the market and the industry in general, the technological leverage that allows customers and partners to imagine new vision products and applications”, says Marc Damhaut
, CEO at Euresys
