Overview
The FireBird 1xCOF100G-4PE8 is Active Silicon's 100 Gbps CoaXPress-over-Fiber frame grabber. It presents a single QSFP28 port carrying up to 100 Gbps over four 25 Gbps lanes and feeds the host through a PCI Express 4.0 x8 interface, so one camera or a fibre-aggregated camera group can stream without hitting a host bandwidth ceiling.
CoaXPress over Fiber extends the CoaXPress machine-vision standard onto optical cabling. That matters when the camera has to sit far from the rack — with the right transceiver module the grabber reaches across kilometres of fibre rather than the few metres a copper CoaXPress link allows. Image data is moved by Active Silicon's ActiveDMA engine, which uses RISC-style processing to keep latency low and CPU involvement at zero.
Key Benefits
100 Gbps on one fibre removes the cabling fan-out of multi-link copper CoaXPress. Kilometre camera reach decouples the sensor from the electrical-noise environment of the cell. PCIe 4.0 x8 host link keeps the grabber from becoming the bottleneck. ActiveDMA transfers with zero CPU intervention, leaving cycles for inspection algorithms.
Applications
High-resolution line-scan inspection, multi-camera 3D and surface-defect systems, flat-panel and semiconductor wafer inspection, sports and broadcast capture, and any vision cell where camera separation or aggregate bandwidth rules out copper CoaXPress.
