What is CoaXPress?

CoaXPress (CXP) is the world’s leading standard for high-speed imaging in professional and industrial imaging applications such as machine vision, medical imaging, life sciences, broadcast and defence.

CoaXPress combines the traditional simplicity of coaxial cable with state of the art high-speed serial data technology. The combination of these two features – coaxial cable and “express” speed – provides a highly desirable solution for high-speed imaging and data transmission.

The standard is hosted by JIIA with working groups from companies around the world.

Technical Summary

CoaXPress (CXP) is an asymmetric high-speed point to point serial communication standard for the transmission of video and still images, scalable over single or multiple coaxial cables. It has a high speed downlink of up to 6.25Gbps per cable for video, images and data, plus a lower speed, 20Mbps uplink for communications and control. Power is also available over the cable (“Power-over-Coax”) and cable lengths of greater than 100m may be achieved.

  • High-speed data rates: up to 6.25 Gbps over a single coax cable and scalable for multiple cables. (e.g. 4 cables gives 25 Gbps, 8 cables give 50 Gbps etc).
  • Roadmap to 10 Gbps and 12.5 Gbps per cable.
  • Long Cable Lengths:  In excess of 100m at 3.125 Gbps and 40m at 6.25 Gbps.
  • Real time behavior with fixed, low latency transmission.
  • Precise triggering capability.
  • Flexible and reliable through use of standard coax – e.g. RG59 and RG6.
  • Ease of integration: image data, communication, control and power over a single coax cable.
  • Cost-effective cabling solutions
  • Hot pluggable.
  • Royalty-free solution.
