Silicom Network Monitoring & Capturing Network Monitoring Adapter Card


Capture Card – Dual SFP+ port card supporting 2x10G Ethernet, half-height, PCIe Gen3 x8 lanes

The Silicom Denmark fbC2XGhh card is a 2x10GE capture solution that performs at full line rate with zero packet loss, on both interfaces.

The card is based on the successful four port, full-height fbC4XGG3 card. Similar to the full-height version, the 2x10GE card uses PCIe Gen3, ensuring that no bottlenecks will affect the packet capture to host memory capability.

It is a high performance OEM hardware platform with dual SFP+ ports, and with a form factor of half-height and half-length, it provides a high level of flexibility for integrating into almost any host platform.

The fbC2XGhh card is part of the fbCAPTURE family which provides a powerful and flexible Software API, as well as standard libpcap integration. Through the integration of fbCAPTURE API, applications gain support for all fbCAPTURE cards, covering Ethernet speeds from 1GE to 100GE.
