There is an increasing demand for higher data rates at the edge. With the ever-decreasing footprint of cameras and video systems and their popularity in safety, security, and quality applications, their adoption has increased dramatically, thereby driving up the data rate demand. In addition, other systems, such as high-speed data logging devices, embedded Web servers and monitoring systems, also require timely data transmission. As the number of nodes in the network continues to increase, the willingness of users to retain the existing ecosystem becomes stronger. Ethernet protocols and security layers, along with the well-known installation, maintenance, and management processes, effectively reduce the total cost of Ownership (TCO) of the network and optimize the return on investment (ROI). Industrial applications focus on network speeds of 10Mbps, as this is sufficient to address the data rate and coverage issues in most current fieldbus applications. In industrial applications, industrial Ethernet is sometimes called single pair Ethernet (SPE), which is often confused with conventional Ethernet. This architecture stems from standards in traditional local area network (LAN) applications, where two or four pairs of twisted-pair wires are used to transfer data at 100Mbps(megabits per second) or 1000Mbps(megabits per second), respectively. The SPEs use only one pair of twisted pair wires for communication speeds between 10Mbps and 10Gbps, and each cable follows a dedicated standard.
