Enterprise IT professionals are challenged to connect a wide assortment of sensor/actuator devices into their structured cabling networks. Many require the power output and high-bandwidth capacity only four-pair ethernet cabling can support. But, for devices with lower power and bandwidth requirements—such as sensors and actuators used for building automation and manufacturing equipment, alarm systems and RFID readers—the use of single-pair ethernet cabling can provide a more cost-effective and space-efficient solution.
