An SFP port is a modular interface on a Gigabit Ethernet switch, router, or server. It accepts SFP or SFP+ transceivers to facilitate data transmission over fiber or copper media. SFP ports provide support for connection types and speeds that are great opportunities for network designers and administrators who are aiming to support performance and. An SFP port on a Gigabit switch is a modular interface that accepts Small Form-Factor Pluggable (SFP) transceiver modules. Unlike fixed RJ45 copper ports, SFP ports support both fiber and copper modules, enabling far longer distances, greater flexibility, and improved scalability in enterprise. Note: For the IE 2000U model (IE 2000U-16TC-GP) that supports PoE, connector pins 3 and 6 supply +48/+54 VDC and pins 1 and 2 are the DC voltage return lines. Figure 51 on page 84 shows the MT-RJ SFP module fiber-optic connector. Warning: Invisible laser radiation may be emitted from disconnected. SFP ports, also known as Small Form-Factor Pluggable ports, are essential components found in a variety of network and storage devices including switches, servers, routers, and network interface cards (NICs).
