The SFP optical fiber module is a hot-swappable small package module in SFP package, the rate can reach 1.25G, and the interface is LC. The SFP optical fiber module is mainly composed of optoelectronic devices, functional circuits and optical interfaces. SFP classification can be divided into rate classification, wavelength classification, and mode classification. So, what are SFPs? What are the types and applications of SFP optical fiber modules?
SFP, short for Small Form Factor Pluggable, is a compact, hot-swappable optical module for telecom and datacom applications. The SFP optical fiber module can be considered as an upgraded version of the GBIC optical module. Unlike GBIC with SC fiber optic interface, SFP has LC interface and the main body size is only about half of GBIC, so that SFP can save more space. SFPs connect the motherboards of network devices such as routers, switches, media converters, or similar devices to fiber optic or electrical cables. At the same time, SFP is a common industrial specification supported by many network device suppliers. It was designed to support SONET, Gigabit Ethernet, Fiber Channel, and other communication standards. And more information can be found in fiber transceiver wiki.
And there are different fiber optic transceiver types. SFP optical fiber modules are not regulated by any official standard system, but are regulated by multilateral agreements (MSAs) between competing manufacturers. SFP is designed according to the GBIC interface and achieves a higher port density (the number of optical modules per centimeter along the edge of the motherboard) than GBIC, which is why SFP is also called mini-GBIC. The associated small-package optical module has a similar size to an SFP, but it is soldered to the motherboard as a pin instead of plugged into an edge card slot.

However, in practical applications, some network equipment manufacturers use the key mechanism to break the compatibility with "universal" SFP, that is, add an authentication process on the device firmware, so that the device only enables the supplier's own optical modules. For example, in 2003, when Cisco routinely updated the Internet Operating System (IOS) for the Catalyst switch line, a feature was added that caused the switch to not accept non-"Cisco-branded" optical modules.
SFP optical fiber module is a small hot-swappable optical transceiver module, which is widely used in communication operations. There are many types of SFP optical fiber modules, such as: BIDI-SFP, electrical port SFP, CWDM SFP, DWDM SFP, SFP+ optical module, etc. In addition, for the same type of XFP, X2, and XENPAK optical modules, SFP optical fiber modules can not only be directly connected to them, but also have a lower cost than them.
