SFP 10G SR vs SFP 10G LR ：What's the difference?

The SFP-10G-SR and SFP-10G-LR are both types of transceiver modules used in networking for 10 Gigabit Ethernet connections, but they are designed for different types of fiber optic cable and for different distances:

1. SFP-10G-SR (Short Range):

   • Distance:Designed for short-range data transmission, typically up to 300 meters.

   • Fiber Type:Uses multi-mode fiber optic cable, which is generally more cost-effective but supports shorter transmission distances compared to single-mode fiber.

   • Wavelength:Typically operates at a wavelength of 850 nm.

   • Applications:Ideal for high-speed connections within the same data center or within a single building, such as in campus networks.

2. SFP-10G-LR (Long Range):

   • Distance:Intended for long-range data transmission, capable of reaching distances up to 10 kilometers.

   • Fiber Type:Uses single-mode fiber optic cable, which allows for longer transmission distances due to its smaller core and single light path.

   • Wavelength:Typically operates at a wavelength of 1310 nm.

   • Applications:Suitable for connections that span longer distances, such as between different buildings in a campus or between sites in a metropolitan area network.

In summary, the primary differences between SFP-10G-SR and SFP-10G-LR modules are the type of fiber they use (multi-mode vs. single-mode), the maximum transmission distance they support (short-range vs. long-range), and their operating wavelengths. The choice between these two types of modules depends largely on the required transmission distance and the type of fiber optic cabling available in the network infrastructure.
