Long-distance (100 m), ultra-high-speed (100 Gbps) data transmission interface

What is CoaXPress-Over-Fiber (COF)?
CoaXPress-Over-Fiber (COF) is a technology that transmits conventional CoaXPress signals over optical fiber,
enabling high-speed data transfer even over long distances.
This allows stable, low-latency transmission of high-resolution image data over distances of up to 100 m.
Traditional CoaXPress (CXP) faced limitations such as short transmission distance, heavy and thick cables, susceptibility to EMI (Electromagnetic Interference), and bandwidth constraints.
By contrast, CoaXPress-Over-Fiber (COF) uses optical fiber to achieve long-distance transmission, higher bandwidth, and EMI resistance, effectively overcoming these issues.
| Item | CoaXPress | CoaXPress over Fiber |
| Cable | Coaxial cable, limited length (5–15 m), heavy and thick |
Optical fiber, transmission up to 100 m, Light and thin |
| Noise Tolerance | Sensitive to EMI, affected by factory noise | Immune to EMI, robust against external noise for stable data transmission |
| Bandwidth | CXP-12 × 4 = up to 50 Gbps | 40 Gbps, 80 Gbps, 100 Gbps+, real-time processing of high-resolution image data |
COF interfaces are widely used in machine vision, industrial inspection, semiconductor and 3D printing equipment,
as well as long-distance environmental monitoring, broadcasting, life sciences, and medical imaging.
