Is PoE switch standard
3af standard, which specifies the maximum power delivered over Ethernet cables. In this configuration, an Ethernet connection includes Power over Ethernet (PoE) (gray cable looping below), and a PoE splitter provides a separate data cable (gray, looping above) and power cable (black, also looping above) for a wireless access point. Power is passed from Power Sourcing Equipment (PSE) over the twisted pairs to Powered Devices (PD) such as IP phones, IP cameras, card. PoE does not reduce network speed, does not waste excessive power when proper cabling standards are. Power over Ethernet switch (or PoE switch) is an access layer technology that combines data signals and electrical power into a single Ethernet cable connection, delivering both to enable a powered device (PD).
