CoaXPress-over-Fiber
CoaXPress-over-Fiber is a light but significant extension of the existing CoaXPress specification to support transport over fiber optics
By using fiber optics connectivity, CoaXPress-over-Fiber benefits from the almost unlimited cable lengths and reduced cable congestion (fiber optics are lighter and thinner than coaxial cables). By leveraging Ethernet Physical Layer standards (IEEE 802.3), CoaXPress-over-Fiber also benefits from the low-cost standard components (such as connectors and cables) and their constant evolution towards higher bandwidths.
Most importantly, CoaXPress-over-Fiber allows CoaXPress to go beyond the physical limitations of coaxial cables in terms of bitrate.
Acquire images from the fastest and highest resolution cameras
- Highest data acquisition rate in the industry
- Up to 5,000 MB/s bandwidth from camera to host PC memory
Line-Scan Triggering Capabilities
Allied Vision frame grabbers offer many capabilities to synchronize line-scan or 1D cameras, sensors and lighting controllers. Frame grabbers can control the camera scanning rate based on the signals received from a motion encoder.
They support continuous web scanning (to inspect infinite, continuously moving surfaces without losing a single line) and discrete object scanning (to acquire the image of objects moving in front of the camera).
Area-Scan Triggering Capabilities
Allied Vision frame grabbers offer many capabilities to synchronize area-scan or 2D cameras, sensors and lighting controllers, for stationery or moving objects in the field of view, or moving cameras.
Benefits

Direct GPU Transfer
-
- Sample programs for AMD DirectGMA and NVIDIA (CUDA) available.
- Direct GPU transfer eliminates unnecessary system memory copies, lowers CPU overhead, and reduces latency, resulting in significant performance improvements in data transfer times for applications.
- Direct capture of image data to GPU memory is available using AMD’s DirectGMA. Compatible with AMD FirePro W5x00 and above and all AMD FirePro S series products.
High-Performance DMA (Direct Memory Access)
-
- Direct transfer into user-allocated memory
- Hardware scatter-gather support
C2C-Link Camera Synchronization
Allows to accurately synchronize multiple area-scan or line-scan cameras connected
-
- to the same card
- to different cards in the same PC
- to different cards in different PCs
Line-Scan Metadata Insertion
When activated, this feature records metadata beside image data. Line metadata are captured every acquired image line. Buffer metadata are only captured when the first image line of a buffer is acquired. The metadata are composed with a configurable set of general purpose event counters, quadrature encoder position counters and/or I/O line status. This feature allows line-scan applications to correlate image data with system events including motion encoder positions.
Flexible Line-Scan Camera Operation With The Rate Converter
- The rate converter is a smart, programmable frequency multiplier/divider.
- Used with motion encoders and line-scan cameras, it allows the user to choose the aspect ratio of the pixels in the image.
- It provides a way to calibrate the acquisition chain to easily reach square (1:1 aspect ratio) pixels.

FAQ
What are the cable options for CoaXPress-over-Fiber?
One of the most important benefits of CoaXPress-over-Fiber is the wide variety of connectivity options already available from multiple companies. The initial connectivity options for CoaXPress-over-Fiber and the Coaxlink QSFP+ at 10 Gbps are SFP+ and QSFP+ (Quad, or four times SFP+) modules.
The advantage of using modules compared to fixed interfaces is that ports can be equipped with any suitable type of transceiver as required by the application. A variety of transmitter and receiver types is available, allowing users to select the appropriate transceiver to provide the required optical reach over multi-mode or single-mode fiber.
What is the maximum cable length with single-mode fibers?
With a standard 40GBASE-ER4 QSFP+ LC DOM Optical Transceiver Module and an LC-Duplex single-mode fiber cable, the maximum cable length is 40 kilometers. This solution is suitable, for example, for video transmission applications.
What is the maximum cable length with multi-mode fibers?
With a standard 40GBASE-SR4 QSFP+ Optical Transceiver Module and an MTP/MPO multi-mode fiber cable, the maximum cable length is 150 meters. This solution is suitable for machine vision applications.
What are the benefits of using CoaXPress-over-Fiber for my application?
- Available as CXP to nGMII (device) or nGMII to CXP (host) Bridge IP Cores
- Ultra-high data/frame rates
- Many accessory and cabling options to cover any length requirement
- Low CPU overhead, low latency, low jitter image acquisition
- Highest camera count per PC performance
- Very competitive cost/performance ratio
- Wide industry acceptance due to JIIA standardization
What are the pros and cons of using fiber optics?
Pros
- First and foremost, cable length is not an issue anymore as fiber connectivity is basically not limited in length.
- Fiber optics provide more bandwidth, as connectivity at 10 and 25 Gbps per fiber is standard today and widely used in data centers.
- Fiber optics are immune to electrical noise, which will be a significant advantage on the production floor and in some medical applications.
- Fiber optics are lighter and smaller in size than the equivalent copper cabling, making it appropriate for applications where this characteristic is essential, like in aircrafts or vehicles.
Cons
- There is no "power over fiber". As signals in fiber optics are transmitted using light, there is no way to transfer power over fiber optics and devices such as cameras must be powered separately.
What are the jitter and latency of CoaXPress-over-Fiber? How do they compare to "traditional" CoaXPress?
CoaXPress-over-Fiber is based on the CoaXPress protocol and it exhibits the same high performance as CoaXPress in terms of jitter and latency. In addition, as CoaXPress-over-Fiber supports higher transmission speed compared to CoaXPress.
