Long-reach, single-pair power over Ethernet (SPoE) solutions

Analog Devices has announced what it claims are the world’s first single-pair power over Ethernet (SPoE) power sourcing equipment (PSE) and power device (PD) solutions to help customers drive greater levels of intelligence at the edge of traditional networks.

The new offerings facilitate powered, last-mile connectivity for factory and building automation through real-time power management, telemetry, extremely low standby power consumption, and ease of installation.

“The Intelligent Edge is one of the most exciting developments of the digital era as computing power is pushed to previously inaccessible applications and locations,” said Leo McHugh, vice president of industrial automation at Analog Devices. “Analog Devices is committed to delivering the unrivalled technology and solutions our customers need to leverage the full potential of the Intelligent Edge in smart buildings and factories as well as many more applications in the future.”

Analog Devices’ new SPoE solutions, LTC4296-1 and LTC9111, address the challenges of providing power and data to devices, even in remote, difficult to access endpoint locations. Analog Devices’ solutions aim to help new families of endpoint applications to be seamlessly powered and accessed across the network and used to assess local factors such as asset health, environmental conditions, security metrics, and more. The localised awareness and control they offer are the building blocks of the digital buildings of tomorrow.

Analog Devices’ SPoE solutions reduce reliance on localised power and batteries by using a single twisted pair of Ethernet cables to provide efficient, reliable, easily installed power at reduced size and weight. Combined with ADI Chronous ADIN1100 and ADIN1110 10BASE-T1L, Industrial Ethernet solutions, customers can reliably transfer both power and data over one kilometre – a significant increase from previous Ethernet standards.
