BitFlow QFi Copper-to-Fiber Converter Module Simplifies Long Distance CoaXPress Imaging Applications

BitFlow, a brand of Advantech, is strengthening its position as a leader in CoaXPress (CXP) machine vision technology by launching its first copper-to-fiber module supporting long distance transmission of data output from a single-link CXP camera to a host PC. Enabling link speeds up to 10Gb per second and cable lengths exceeding one kilometer, the BitFlow QFi module is a simple, cost-effective alternative to conventional methods of extending CXP transmission.

Compared to other interfaces like USB 3.0 or GigE, the CoaXPress interface is prized in machine vision circles because it can transmit high-speed data over much greater distances—up to 100 meters—without the need for repeaters or signal boosters. Longer than 100 meters, however, system integrators must convert a CXP camera’s output to optical signals using a dedicated set of converter boxes linked to a fiber cable between the camera and the PC. At the PC endpoint, the fiber signal is converted back to copper and an additional coaxial cable is connected into a CXP frame grabber. Besides being expensive, this approach introduces potential failure points to the system, is difficult to diagnose, and may increase signal latency.

Instead of multiple converters and cables, a single BitFlow QFi bridges the gap between copper and fiber by directly connecting to the CXP camera using a standard coaxial cable. Depending on the CXP version, this cable can extend 40 meters or longer, giving the integrator more options for where to mount the QFi. The QFi outputs camera data via an SFP+ compatible fiber cable assembly and into a BitFlow Claxon™ quad-link CoaXPress over Fiber (CoF) frame grabber installed in the host PC. A maximum of four QFi modules can be connected to a Claxon frame grabber, opening up opportunities to support multi-camera system configurations or a single multi-link camera to deliver speeds up to 40Gb per second.

The BitFlow QFi module is engineered as a complete system solution. It will supply a maximum of 13 Watts of power to a connected CXP camera, eliminating the need for a separate power source. In addition, it fully supports an uplink channel for camera configuration and control, triggering and firmware updates. It is also compatible with CXP-1 to CXP-12 cameras for use cases requiring link speeds from 1.25Gb to 12.5Gb per second.

Emerging Markets for CXP

Applications for the BitFlow QFi/Claxon solution can increasingly be found in the industrial, infrastructure, or sporting sectors:

• Industrial - Bridge inspection, pipeline monitoring, high voltage monitoring.
• Long Range Surveillance - Rocket launches, destructive testing, environmental monitoring.
• Sporting events - Multi-angle replay analysis, goal-line technology, player tracking.

"What these applications all share in common is the need for high resolution and image clarity at significant cabling distances, sometimes well over one kilometer," noted Donal Waide, Director of Business Development, Industrial Cloud & Video Group, Advantech. "Our new QFi solution not only helps customers meet those requirements, we ruggedly engineered it to reliably operate in harsh environments with precise timing and synchronization. Plus, it is very simple to integrate with existing monitoring systems."
