The term SPE describes the new single pair Ethernet technology based on transmission standards according to IEEE 802.3.
A high electromagnetic compatibility (EMC) is required for SPE cables, connectors and transmission systems according to IEEE 802.3. EMC can be verified by measuring the coupling attenuation according to IEC 62153-4-7/-4-9 or alternatively with the burst test according to IEC 61000-4-4.
There is a direct relationship between the two test methods. The coupling attenuation evaluates the results in dB and the burst test in KV. Here the question arises whether the burst values can be given directly for measured coupling attenuations.
On the example of the SPE 100 Base-T1 application, the correlation between the coupling attenuation and the burst test is investigated.
The following paper describes the burst test according to IEC 61000-4-4 as well as the measurement of the coupling loss according to IEC 62153-4-7/-4-9 on SPE cables, SPE connectors and SPE cabling systems from frequencies of 100 kHz.
The correlation of the measurement results of burst test and coupling attenuation is presented and discussed using the example of the 100Base-T1 application.
