Single pair ethernet solutions

Single pair ethernet solutions

The rising complexity of networked devices, such as sensors, actuators, and controllers, used across various sectors like industrial automation, transportation, smart cities, and defense, presents significant challenges for Ethernet connectivity. These challenges include long cabling distances, bandwidth limitations from older connectivity systems, and managing multiple protocols simultaneously.

To address these challenges, there’s a growing demand for a smaller, lighter, and more cost-effective version of Ethernet known as Single Pair Ethernet (SPE). SPE utilizes just one pair of twisted copper wires and offers:

  • Data transmission speeds ranging from 10 Mbit/s to 10 Gbit/s
  • Power over Data Line (PoDL) up to 52 Watts
  • Distances ranging from 15 meters (at 10, 100, and 1,000 Mbit/s) to 1,000 meters (at 10 Mbit/s)

Drawing upon our expertise in precision, durability, and resilience to extreme conditions, we integrate SPE’s unique features with our high-reliability, high-performance sealed connectors. This integration opens up new possibilities for SPE connectivity in industrial production lines and defense UAVs, elevating their performance and capabilities to new heights.
