CoaXPress
high speed serial data interface over coaxial cable
CoaXPress (CXP) is a digital interface standard developed for high-speed image data transmission in machine vision applications.
The name is a portmanteau of 'express' and 'coaxial' to emphasize CoaXPress is faster than other standards (e.g. Camera Link or GigE Vision) and uses 75 ohm coaxial cables as the physical transmission medium.
CoaXPress is mostly used in digital imaging applications but it is also suitable for high-speed transmission of universal digital data.
A 'device' that generates and transmits data (e.g. an industrial digital camera) is connected with one or more coaxial cables to a 'host' that receives the data (e.g. a frame grabber board in a computer). The CoaXPress standard 1.0 and 1.1 supports bit rates up to 6.25 Gbit/s per coaxial cable and the new 2.0 standard supports bit rates up to 12.5 Gbit/s per coaxial cable from the 'device' to the 'host'. The number of cables is not limited by the standard. Some recent CoaXPress cameras and frame grabbers use 8 coaxial cables providing a maximum image data rate of about 48 GB/s.
The public source identifies “CoaXPress” as high speed serial data interface over coaxial cable. This brief keeps that definition visible, then builds a research path around CoaXPress, high and speed.
Why this record matters
A short description can identify a subject without explaining its stakes. For “CoaXPress”, the useful work is to connect “high speed serial data interface over coaxial cable” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated May 13, 2026. The linked authority identifier is Q5137564.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
