The alliance has released NBASE-T PHY interface specifications, and has adopted a first version of a single-port USXGMII MAC-PHY specification.

  • The PHY specifications support 2.5 Gbps and 5 Gbps rates over 100m of Category 5e or better cabling with a bit error rate of less than 10e-12.
  • The MAC-PHY specification facilitates system development by enabling simple multivendor interconnection of MAC and PHY components.

The alliance is exploring the industry need for additional specifications to further enable the market.
