Until the CoaXPress v2.1 standard was released in 2021, the only physical medium between cameras, PCs, and frame grabbers for the CoaXPress (CXP) interface had been 75Ω coaxial cable. For most vision applications, then and now, the CXP 2.1 interface — with its ability to transfer data at up to 12.5 Gbps (Gigabits per Second) per link over a single coaxial cable — perfectly suited high-throughput inspection systems, quality control and factory automation needs. CXP 2.1 over coaxial cable is faster and more stable than GigE Vision, USB3 or Camera Link, and has proven to be the ideal balance between costs and growing requirements for faster speeds, extended length cables, heat dissipation, and power delivery.
So, who would want to change that winning formula?
