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 defense.

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 12.5 Gbps per cable for video, images and data, plus a lower speed uplink up to 42 Mbps 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 12.5 Gbps over a single coax cable and scalable for multiple cables. (e.g. 4 cables gives 50 Gbps, 8 cables give 100 Gbps etc).
• Long Cable Lengths:  In excess of 100m at 3.125 Gbps and 35m at 12.5 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.
