Product Family


The XPliant® CNX680XX and CNX780XX families of optimized Ethernet switches are targeted for the largest segment of the data center market. The XP60 family brings programmable Ethernet switching features to the campus, embedded, and carrier access markets with devices that scale from 280Gbps to 720 Gbps. The CNX70 family of programmable Ethernet switch devices scales from 1Tbps to 1.8Tbps and provides cost-effective seamless 1GBASE-T to 10GBASE-T and 10GbE to 25GbE access connectivity upgrades for enterprise, data center, and carrier networks with support for 40GbE/100GbE uplink connectivity. The new CNX60 and CNX70 families, combined with the production qualified CN880xx family of products now extends Cavium's XPliant programmable architecture from 3.2Tbps down to 280Gbps.

Cavium's CNX680XX and CNX780XX families are fully software compatible with the volume shipping CNX80 family and leverage the same field proven programmable engines. This enables transparent software migration for current CNX80 customers, as well as use of the entire XPliant suite of software tools.
