Euresys CoaXPress-Over-Fiber

Top-tier Performance and Connectivity Using Fibre-Optic Instrastructure

The Euresys CoaXPress-over-Fiber frame grabbers are light but significant extensions of the CoaXPress solutions, designed to deliver top-tier performance and connectivity. By extending the proven CoaXPress protocol onto fibre-optic infrastructure, these solutions allow for improved resolution, throughput and cable-length boundaries while maintaining the low latency and deterministic behavior that vision-systems demand.

With the CoaXPress-over-Fiber extension, you get all the reliability and performance of the CoaXPress protocol including ultra-high data rates, low jitter and minimal host CPU overhead, while benefitting from the scalability, reach and noise immunity of fibre-optic connectivity.

Whether your workflow requires very long cable runs, high-resolution sensors, high frame-rates or electrically noisy environments, this technology creates a next-level foundation for industrial vision systems.

Coaxlink CXP-12 to QSFP+ Converter

The Euresys Coaxlink CXP-12 to QSFP+ Converter is a powerful bridge device engineered to extend and enhance high-bandwidth imaging systems. It enables seamless integration between a CXP-12 camera interface and a CoaXPress-over-fiber host link, providing four Micro-BNC CXP-12 inputs on the camera side and a single QSFP+ optical link on the frame-grabber side. With support for up to 5,000 MB/s of aggregated camera bandwidth and PoCXP (Power over CoaXPress) capability, the converter ensures robust, high-performance signal acquisition and transmission in demanding machine-vision environments.

In modern vision systems where long cable runs, signal integrity, and electromagnetic immunity are paramount, this converter plays a vital role. By shifting from copper-coaxial to fibre-optic transport via the QSFP+ interface, it allows deployment of high-speed CXP-12 cameras over multi-mode fiber up to ~150 m or single-mode fiber up to ~40 km. This means you can situate cameras far from the host PC or in electrically noisy environments without sacrificing bandwidth or latency, making it ideal for large-scale installations, remote vision systems, and high-throughput inspection lines.
