As the industry adopts the latest generation of PoE technology for managing data and power over a single Ethernet cable, users face the challenge of making pre-standard powered devices (PDs) work alongside new IEEE 802.3bt-2018-compliant PDs in an existing Ethernet infrastructure. Microchip Technology Inc. has eased the transition with IEEE 802.3bt-2018-compliant PoE injectors and midspans for users and power sourcing equipment (PSE) chipsets for system developers that enable both pre-standard and IEEE-compliant PDs to receive up to 90W of power without changing switches or cabling.
