Single Pair Ethernet Infrastructure
for Industrial Systems
Zemfyre develops and manufactures industrial Ethernet solutions powered by Single Pair Ethernet (SPE), enabling seamless end-to-end connectivity from sensors and field-level devices to control systems and the cloud.
Made in Canada. Deployed in 20+ countries.
Zemfyre designs and manufactures Single Pair Ethernet infrastructure: switches, media converters, power controllers, and field devices that carry Ethernet and power to the far end of industrial and building networks.
Our founders, Yuri Luskind and Alexandre Gourari, spent their careers building networks that can't go down, at RuggedCom and iS5 Communications and across substation automation and mission-critical communications. Zemfyre brings that standard to the field level.
Our products are engineered and built in Canada, covered by patents including a granted US patent on our PoDL-to-PoE media converter, and deployed by OEMs and system integrators in more than 20 countries.
Expanding Ethernet to the field
Zemfyre works inside the industry bodies shaping how Single Pair Ethernet gets deployed.
For decades, Ethernet has stopped at the controller. The sensors, actuators, and meters below it still sit behind fieldbuses, 4–20 mA loops, and gateways. Single Pair Ethernet closes that gap, and it only works if every manufacturer builds to the same rules. IEEE 802.3cg defines 10BASE-T1L, and TIA-568.5 defines the cabling it runs on. Zemfyre builds to both, so our switches and converters share a physical layer with SPE devices from every manufacturer that follows the standard.
The Single Pair Ethernet Association brings together the silicon, connector, cable, and device makers building out the ecosystem. The TIA SPE Consortium focuses on SPE in building cabling infrastructure. Zemfyre is a member of both.
At BICSI, Embedded World, Hannover Messe, SPS, and IMTS, you'll find Zemfyre exhibiting in the Single Pair Ethernet Association booth.
