The IEEE standard for the base PoE switches is 802. 3at for PoE+, and 802. PoE and PoE+ transmit power over two pairs of twisted-pair wires in their cables, while the PoE++ variants use four pairs of twisted-pair wires. The splitter is the silver and black box in the middle between the wiring junction box (left) and the access point (right). The PoE connection eliminates the need for a nearby power outlet. In another common configuration, the access point or other connected device includes internal PoE splitting. Power over Ethernet (PoE) switches combine data and power delivery into a single Ethernet cable, simplifying deployment of devices such as access points, IP cameras, VoIP phones, and IoT equipment. PoE does not reduce network speed, does not waste excessive power when proper cabling standards are. Therefore, everyone is concerned about whether PoE switches will affect speed. Key Benefits of Power over. PoE switches (Type 1) comply with the IEEE 802. 3af standard, which specifies the maximum power delivered over Ethernet cables.
