Kickstart your 10BASE-T1L development
Supporting text:Single Pair Ethernet (SPE) is the emerging industry standard that facilitates connections from the field to the cloud using only one twisted pair of wire. SPE enables parallel power transfer and continuous IP-communication for implementing 10BASE-T1L applications per IEEE 802.3cg standards.
Industry stats shown in blue and green quad below.Green section: Industrial Ethernet accounts for 68% of new installed nodes section: While Fieldbus declined to 24%. Source: HMS NetworksBlue
Blue section: $3.26B Global SPE market in 2022 Source: Worldwide Research Green section: Projected to be nearly $4B in 2028 at a CAGR of 4.56%.
