Ethernet-APL
What Is Ethernet-APL?
Ethernet-APL (Advanced Physical Layer) is an enhanced physical layer for single-pair Ethernet based on the IEEE 802.3cg 10BASE-T1L standard. It is designed to meet the rigorous demands of field process automation and usage in hazardous environments. Ethernet-APL simplifies network architecture by supporting both data and power transmissions over a single connection for more efficient and cost-effective installations. Ethernet-APL also provides high-speed, 10 Mbit/s full-duplex communication over distances up to 1,000 meters. These features combined make Ethernet-APL ideal for building scalable and reliable industrial networks, revolutionizing Ethernet accessibility for field-level instruments.
