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