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.

CoaXPress combines the elegant simplicity of coaxial cable with state of the art high speed serial data technology. The combination of these two highly desirable features - standard coaxial cable and "express" speed - provides a revolutionary leap forward in high speed image and data transmission.

Current digital video interfaces such as Camera Link®, GigE Vision® and FireWire® all have limitations and do not meet the requirements of new generation imaging applications. The primary driving force behind the development of CoaXPress has been the need to overcome the various limitations - primarily cable length, speed and ease of use. CoaXPress combines the best features of each of these existing interfaces into just one interface solution:

• High Data rates: up to 6.25Gbps over a single coax cable and up to 25Gbps using four cables.
  
  
• Long Cable Lengths: In excess of 100m (without any hubs, repeaters etc.).
  
  
• Real time behavior through fixed, low latency.
  
  
• Precise triggering capability.
  
  
• Flexible and reliable through use of standard coax - e.g. RG59 & RG6.
  
  
• Ease of integration: video, communication, control and power over a single coax cable.
  
  
• Cost effective cable solution.
  
  
• Hot pluggable.
  
  
• Royalty-free solution.
