The ports (gold finger ends) of SFP optical modules are hot-swappable I/O interfaces (referring to input/output interfaces). The gold fingers are generally covered with copper or gold on the surface to meet the wear resistance requirements for hot-swappable plugging. It is commonly found in network devices such as switches, routers, and media converters. Its main function is to convert signals and transmit data. It has strong flexibility and is suitable for a variety of products. The SFP ports on the switch support both SFP electrical port modules and SFP optical port modules.
The SFP port complies with the IEEE 802.3ab standard (such as 1000BASE-T) and is backward compatible, supporting 10/100/1000Mbps, with a maximum transmission distance of up to 1250Mbps (the SFP port of the switch supports 100/1000Mbps). It can be switched with the ports of 1000BASE-SX, 1000BASE-LX/LH, 1000BASE-ZX or 1000BASE-BX10-D/U.
The SFP ports of a gigabit switch can be used to expand the switching function of the entire network by connecting various types of optical fibers (such as single-mode and multi-mode optical fibers) and network patch cords (such as Cat5e and Cat6). However, before using the SFP port of a gigabit switch, an SFP optical module (or an electrical port module) must be inserted first. Then, power grid transmission is carried out, and then data transmission is conducted using optical fiber patch cords and network patch cords. Nowadays, all enterprise-level switches on the market have at least two SFP ports (to achieve long-distance signal transmission), and can build ring or star network topologies between different buildings, floors or areas through the connection of optical fibers and network patch cords and other cables.
