(Summary description)POE (Power Over Ethernet) refers to the use of IP-based terminals (such as IP phones, wireless LAN access points AP, network cameras) without any changes to the existing Ethernet Cat.5 cabling infrastructure. Etc.) While transmitting data signals, it can also provide DC power supply technology for such devices. The POE technology can ensure the normal operation of the existing network while ensuring the safety of the existing structured cabling, minimizing costs. POE is also known as a local area network-based power supply system (PoL, Power over LAN) or Active Ethernet (Active Ethernet), sometimes also referred to as Power over Ethernet, which is the use of existing standard Ethernet transmission cables to simultaneously transmit data and The latest standard specification of electric power, and maintains compatibility with existing Ethernet systems and users. The IEEE 802.3af standard is a new standard based on the POE of the Power over Ethernet system. It adds a related standard for direct power supply through the network cable on the basis of IEEE 802.3. It is an extension of the existing Ethernet standard and the first international standard for power distribution. standard.
