This diploma thesis deals with the design and implementation of a hardware prototype of a multi-standard media converter for Single Pair Ethernet technologies. The proposed device enables the interconnection of a standard Ethernet interface with the 100BASE-T1, 10BASE-T1L and 10BASE-T1S physical layers through a central Ethernet switch. The thesis includes an overview of SPE technology, selection of suitable Ethernet switches and PHY circuits, design of the overall device architecture, implementation of the printed circuit board and development of software support based on the Linux operating system and the Yocto Project environment. The prototype was verified by measuring throughput, latency, communication recovery after link interruption and long-term stability. The results confirmed the functionality of interconnection between the individual physical layers, operation of the 10BASE-T1S interface in both point-to-point and multidrop modes, and stable long-term operation of the device.
