Exablaze is now part of Cisco.


Layer 1 matrix switching is an innovative solution for building low latency networks. It facilitates tapping into connections (for network monitoring), patching connections between ports (for dynamic network reconfiguration) and fanning-out connections from one port to many (for low latency broadcast/multicast) operations.

While Exablaze Layer 1 switches are 'packet aware', no packet processing is performed on the critical path. This makes them incredibly fast. Average latencies through the device are under 5ns while minimum latencies are less than 3ns .

The ExaLINK Hydra 160 is the highest density layer 1 switch on the market. With 20 QSFP-DD ports, it hosts up to 160 10GbE links in a single rack unit.

Exablaze is more than just a Layer 1 Switch vendor. We build and supply an entire ecosystem of network products including fully featured 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 ultra-low latency aggregation, and complete layer 2 (L2) switching and a high precision, deep-buffered tap/aggregation. A switch form factor FPGA application platform are also available.

ExaNIC network adapters are the lowest latency, most feature packed network interfaces on the market. The ExaNIC X25 device offers trigger to response times of under 600ns. Meanwhile the ExaNIC HPT offers 0.25ns (250ps) resolution measurement and the ExaNIC GM is a GPS synchronized PTP Grandmaster. All ExaNIC devices operate with libexanic and ExaSOCK , our free and open source software libraries.

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.
