T1L Ethernet (10BASE-T1L) enables IP communication over single-pair twisted wiring at 10 Mbps across distances up to 1 kilometer. Unlike traditional Ethernet requiring multiple wire pairs, T1L uses one pair, compatible with existing building cabling.
This can help eliminate the need to pull new cables through walls and conduit, helping to reduce installation costs and operational disruption. T1L supports direct IP addressing for sensors and controllers. The IEEE 802.3 standard promotes vendor interoperability.
