SFP modules can be used for both short and long distance connections, depending on the type of SFP module and fiber type selected.
For short distance connections, a common type of SFP module is the Multimode Fiber SFP module. Multimode Fiber SFP modules are typically suitable for short distance transmission, such as connections within a data center or in a local area network (LAN) environment. Multimode Fiber SFP modules support transmission distances typically in the range of a few hundred meters, depending on the type of multimode fiber used (e.g., OM1, OM2, OM3, OM4, etc.) as well as the quality of the fiber and other factors.
For long distance connections, a common type of SFP module is the Single-mode Fiber (SFP) SFP module. Single-mode fiber SFP modules are suitable for longer distance transmissions, such as wide area network (WAN) connections across a large area or connections between remote offices. Single-mode fiber SFP modules can support transmission distances ranging from tens of kilometers to hundreds of kilometers, depending on the quality of the fiber, transmission power, and other factors.
The appropriate SFP module type and fiber type need to be selected based on specific network needs and distance requirements. It is also important to ensure that the SFP module type and fiber type at both ends match to ensure compatibility and reliability of the fiber connection.
