Ethernet QSFP+ Optics
QSFP+ 40GBASE-SR4 Optics for Intel® Ethernet Converged Network Adapters
deliver proven, reliable solutions for
deployments of high density Ethernet
for unied 10GbE and 40GbE network
connections. Customers can move ef-
ciently to 40GbE for high bandwidth
application requirements such as content
distribution, high-end virtualization using
multiple CPUs, network appliances, and
Applications Delivery Controllers (ACD)
used for content caching, load balancing,
and compression. To ensure maximum
exibility, Intel supports the ability to use
any combination of Intel® Ethernet QSFP+
Optic, Intel® Ethernet QSFP+ Twinaxial
Cable, or Intel® Ethernet QSFP+ Breakout
Cable. This enables customers to create
the conguration that best meets the
needs of their data center environment,
while ensuring compatibility between
adapter and accessories.
