The SFP port on the PoE switch or PoE injector must be equipped with an SFP optical module and an optical fiber jumper to realize data transmission. While the RJ45 port can transport the data only through a CAT5E or CAT6 network cable. What is Power over Ethernet (PoE)? Power over Ethernet (PoE) is technology that passes electric power and data over twisted-pair Ethernet cable to wireless access points, IP cameras, and VoIP phones. This eliminates the need for separate power adapters, reducing cable clutter and. Ethernet switch port types define the performance, scalability, and architecture of modern networks. This technology allows the network cables to carry electrical power to Wi-Fi access points, IP cameras, and other networked. The SFP port is an interface that realizes gigabit photoelectric signal conversion, and the maximum transmission rate can reach 1000Mbps (PROCET SFP port PoE switches and SFP PoE injectors support both 100 and 1000Mbps, self-adaptation).
