100GBASE-CR4 Test Points and Test Fixtures

Application Notes

In order for Ethernet stations to be able to communicate in a compatible manner, all stations must adhere rigidly to the exact specification of physical media signals defined in the appropriate clauses of the Ethernet standards. Communication by way of the ISO/IEC 8802-3 [IEEE Std 802.3] Local Area Network requires complete compatibility at the Physical Medium interface (that is, the physical cable interface equipment connector),referred to as the medium dependent interface (MDI).

 

Introduction

The application note will provide a detailed technical overview of the 100GBASE-CR4 test point specifications and test fixtures to implement the testing of physical media signals at the MDI twinaxial copper cable assemblies. These specifications represent milestones in the evolution of compatibility conformance testing of Ethernet physical layer signals and copper cabling media supporting data rates of 100 Gb/s (signaling rate of 25.78125 GBd). Revisions of the TP2/TP3 HCB test fixture design depicting insertion loss improvements based on design attributes will be illustrated. Considerations for the viability of open ended test fixture measurements (i.e., tested in an unmated state) is explored using Keysight’s physical layer test software (PLTS) with automatic fixture removal (AFR) software.
