FBC4CGG3 – Quad Port Capture Card – unprecedented port density with 16x10GE

The Silicom FBC4CGG3 Capture card’s quad QSPF28 ports offers an unprecedented 10GE port density for network connectivity and line rate capture with zero packet loss and hardware packet processing. Support for 4×40GE can be customized.

The FBC4CGG3 capture card is based on cutting edge AMD® FPGA technology, providing packet filtering, advanced processing, traffic management, load balancing and host offloading mechanisms.

This high performance hardware platform connect to the network using QSFP28/QSFP+ modules and performs packet processing, while delivering a sustained throughput to host memory of up to 112 Gbps. The use of QSFP28 cages allows use of QSFP+ to support 16x10GE using breakout cables. For any long or mid-term installation, using breakout cables is simply an alternative installation step.

16×10GE in one PCIe card is ideal for monitoring load balanced or redundant networks, without having to use fully parallel monitoring systems. And this is at the same cost as monitoring only the primary links.

The advantage of having this high port density is that with a single PCI card you can connect to many networks to filter or aggregate the traffic and pass on traffic to host or relay or load balance to other devices via the Tx parts of the optical connectors.

Using the Tx connectors allows the deployment to function as a packet broker while also performing capture and application acceleration on the host system, as well as fully or partially relaying the capture and processed traffic.

In many deployments using a 16×10GE card, can eliminate the dependency on expensive 3rd party packet brokers or aggregator devices. Hereby also reducing the management cost and complications of keeping configuration of shared system deployments in sync

The card uses a single-slot, 16-lane PCIe slot to enable effective traffic management and load balancing, also in NUMA environments.

The card comes with active cooling, a sturdy PCB and a braced FPGA, avoiding the risks associated with PCB vibration and transport.
