Look for power trade-offs in 10GBASE-T Ethernet

Posted: 25 Jan 2008     Print Version  Bookmark and Share

Keywords:10GBASE-T Ethernet  network adapter 

The marketplace is ready for a speed upshift from the network: commodity servers have ample CPU horsepower and IO-plane performance, and many applications are pushing the bandwidth requirements for both servers and the core data-centre network.

However, the increased signal-processing requirements imposed by the 10GBASE-T channel mean that an early-generation 10GBASE-T Physical Transceiver (PHY) consumes significantly more power than a mature 1000BASE-T transceiver or conventional coax- or fibre-optic-based transceivers. Switch products face a relatively simple set of design trade-offs as power improvements on 10GBASE-T transceivers drive denser 10Gbps switches. Designers need to ensure that footprint, power and cooling requirements for the PHY silicon are met for their various legacy and upcoming platform designs.
