NBASE-T Physical Layer Specification version 2.3

NBASE-T PHY specification describes a new copper PHYs operating at new rates of 2.5Gbps/5Gbps as well as IEEE Std 802.3 100M/1G and 10G data rates.

NBASE-T Alliance members made contributions to the development of IEEE 802.3bz for PHY and system level requirements. NBASE-T/IEEE 802.3bz PHY itself is similar to 10GBASE-T PHY specified in Clause 55 of IEEE 802.3-2012 with a few key differences. This document outlines the differences between a 10GBASE-T PHY, NBASE-T PHY and IEEE 802.3bz. This document provides appropriate references to IEEE 802.3bz for common with NBASE-T as well describes NBASE-T features not covered by IEEE 802.3bz.
