The 11801 standard, which is relevant for SPE cabling, deals intensively with all cable and transmission parameters such as cable length, bandwidth, as well as attenuation, near-end cross -talk attenuation( NEXT) and far-end cross-talk attenuation( FEXT). In addition, it is also about the connector face of the SPE connector, which is specified in the IEC 63171 standards with the environmental characteristics defined in the MICE concept.
In addition to cabling, topology also plays a crucial role in single-pair Ethernet. SPE cabling can be set up in star topology with an SPE switch or in line topology. It is suitable for automotive technology and for Industrial Ethernet because connections can be realized via a single-pair cable that is looped through from consumer to consumer. This means, for example, that different functions can be controlled in different areas within a motor vehicle. The situation is different with the star topology, where each function unit must be connected to the SPE switch via a separate cable.
