The latest IEEE 802.3ap v3.3 standard defines a set of informative characteristics for the operation of 10Gbps Backplane Ethernet (10GbE). Primarily, this standard (10GBASE-KR) is intended for backplane configurations utilizing two connectors with controlled impedance in differential signaling environments with possible lengths of up to 1 meter (39 in) on copper based printed circuit boards. The performance of such an interconnect is highly dependant on implementation.

Molex has developed industry leading backplane interconnect solutions that exceed the IEEE 802.3ap v3.3, 10GBASE-KR standard with margin. The Molex GbX I-Trac and Impact backplane products demonstrate compliance for 10GBASE-KR platform designs with a wide range of reference interconnect channels. The following data was measured using the guidelines provided in the IEEE 802.3ap v3.3 specification using the Molex Impact and I-Trac 1 meter reference backplane channels.
