Power over may refer to various forms of powering devices over data links:

  • Power over eSATA (eSATAp), a variant of eSATA also delivering power over the same cable (but not the same wires inside the cable)
  • Power over Ethernet (PoE), a method to power devices over their Ethernet cable (shared wires for data and power)
  • Power over fiber (PoF), delivering power over optical (data) links (shared fibers for data and power)
  • Power over LAN, a PoE-predecessor originally by PowerDsine, now Microsemi (shared wires for data and power)
