SPE (single-pair Ethernet)

An Ethernet variant based on a single 100Ω twisted-pair cable rather than the more-common four-pair configuration. Originally developed for automotive and industrial control applications, it has been adopted for Internet of Things (IOT) and other remotely-located devices. Capable of full-duplex data transmission speeds of up to 1Gbps over 15m (50ft), and extending to up to 1km (3,280ft) at 10Mbps. Most commonly used connectors used are the IEC 63171-1 (Type 1) “LC” style and the IEC 63171-6 industrial style. Used in conjunction with a PoE (Power over Ethernet)/PoDL (Power over Data Line) feed of up to 50w, remote Ethernet devices such as video cameras can be powered and operated over a single-pair cable.
