The intention of this specification is to present the general RF requirements and test methodologies for physical layer communication channel and its components according to Figure 1 to enable 1000 Class 2/2.5/5/10GBASE-T1 technology using fully shielded cables and connectors for Automotive Ethernet applications. The requirements and test methods are described additionally for 1000BASE-T1 applications on fully shielded cabling to allow backward compatibility of components to class 2 requirements: This provides the possibility to qualify components, cable assemblies and channels for any of the speed grades defined in Chapter 3.1 with only one set of test groups. A single measurement result can be compared to the requirements of a multiple number of speed grades if the maximum frequency settings correspond to the fastest speed grade. The requirements for class 2 and for speed grade 1G in this document are the same. Thus, re-qualifications of 1G components, cable assemblies and channels are not necessary. Unshielded and shielded class 1 channels and components for 1000BASE-T1 are not in scope of this document since these topics are covered in ISO 21111-12. These requirements are related to signal integrity and EMC behaviour of the communication channel. The link segment requirements for 1000BASE-T1 according to [1] apart from mode conversion requirements and 2.5G/5G/10GBASE-T1 according [2] shall be met. The fully shielded differential cable is not limited to a specific construction, as no specific mechanical requirements are defined. Common types of shielded differential cables are STP, SDP, SPP, STQ, twin-axial cables or others. The qualification of shielded cabling systems and components shall be done under well-defined setup to make results comparable. This document defines electrical parameters to be tested for the complete communication channel between two Ethernet nodes, for cable assemblies and cables and connectors as a single component of this communication channel. It contains test procedures, measurement setups and electrical requirements and shall be used as a standardized common scale for the evaluation of complete channels, cable assemblies and cables and connectors. Electrical requirements on the communication channel are also stated. Other functional requirements such as mechanical and climatic stress as well as application dependent EMC relevant parameters may also be required but would be specified by the customer (OEM) and are not the focus of this document See the full scope in Annex (includes a graph)
