Exablaze is now part of Cisco.


ExaNIC network interface cards are optimized for situations where every nanosecond of latency counts, such as financial trading applications. The devices function as a drop-in replacement NIC, yet offer up to 10x the latency performance, using our powerful software and tools. In addition to low-latency performance, the cards feature out-of-the-box timestamping and time synchronization features which make them ideal for packet capture. Enhanced ExaNIC devices are available with extended timing and synchronization capabilities.

All ExaNIC devices are FPGA based. This extends the useful life of the devices by allow in-field upgrades, and allows users make use of customizable SmartNIC functionality. Extended and enhanced ExaNICs with larger FPGAs are also available.

The ExaNIC X10 is a 2 port, 10GbE low latency, Ethernet network adapter. It is specifically designed to accelerate low latency applications, offering latencies as low as 740ns.

All ExaNIC network interfaces cards are built using FPGA devices. In addition to implementing the fastest (lowest latency) network adapters, ExaNIC Network adapters can be extended with SmartNIC functionality using our ExaNIC Firmware Development Kits (FDKs).


Software, tools and drivers for ExaNIC devices are free and open-source. Unmodified applications can benefit from ExaNICs latency performance using in-place sockets acceleration, while a direct access API is also available for custom network processing needs. High-rate packet capture is also available.

ExaSOCK enables automatic acceleration of unmodified, low-latency TCP/IP network applications. It is free and open source, and available for all ExaNIC network adapters.

Exablaze is more than just a NIC vendor. We build and supply an entire ecosystem of network products including low latency switches, timestamping devices, optics and cables. Everything needed to build a high performance, low latency network system is available from Exablaze. Here's a few examples:

ExaLINK switches from Exablaze are the lowest latency network switches on the market. The devices include a high density layer 1 (L1) matrix switching, ultra-low latency aggregation, and complete layer 2 (L2) switching. A high precision, deep-buffered tap/aggregation switch and custom switch form factor FPGA application platform are also available.

All ExaNICs are FPGA based. This makes them fast, flexible, and field upgradable. Users can also implement custom network processing applications on many ExaNIC devices using the ExaNIC Firmware Development Kit (FDK) for these devices. Large FPGA devices are also available including the ExaNIC V5P and ExaNIC V9P .

Exablaze supplies high quality SFP+ and QSFP optical transceivers . Transceivers are available in short and long range variants for 1G, 10G and 40G speeds. Note: Exablaze does not require that customers use our branded transceivers. We try to remain compatible with all reasonable quality 3rd party SFP+/QSFP transceivers on the market.

Exablaze supplies high quality direct attach (twinax) cables in a variety of lengths and connector options. We can provide SFP+ to SFP+, QSFP to QSFP, and QSFP to SFP+ breakout cables. Note: Exablaze does not require that customers use our branded twinax cables. We try to remain compatible with all reasonable quality 3rd party cables on the market.
