IEEE 802.3bt Compliance and PoE Interoperability
IEEE802.3bt compliance is the foundation of interoperability and safety for any PoE enabled system. The use of non-compliant Power Sourcing Equipment (PSE) increases the risk that equipment connected to the system might not operate correctly or can even be damaged. This scenario is further intensified with the release of the new 802.3bt standard expanding the array of equipment using PoE and the increased available power levels of up to 90W (sourced).
Sifos Technologies and UNH-IOL have established themselves as first and third-party houses for PoE suite testing.
Sifos Technologies provides a one-box solution to facilitate complete first-party testing and analysis of Power Sourcing Equipment (PSE) behaviors and overall compliance based on the IEEE 802.3bt specification. Sifos test coverage exceeds 95% of 802.3bt PSE PICS.
The Ethernet Alliance (EA) is a consortium of leading industry experts, university, and government professionals, and component vendors that has created a PoE Certification Program. This program is aimed specifically at simplifying the certification and identification of PoE products that are compliant to the IEEE802.3bt PoE standard through the use of logos that can be affixed to PoE equipment and a Certified Product Registry.
