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

The SFP 10G SR and SFP 10G LR are both types of transceiver modules used in network hardware for data communication, but they are designed for different fiber optic cable types and transmission distances:

1. SFP 10G SR (Short Range):

   • Fiber Type:Designed to work with multimode fiber (MMF).

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

   • Transmission Distance:Suitable for short distances, generally up to 300 meters (about 984 feet).

   • Applications:Commonly used in data centers and intra-building connections where the transmission distances are short.

2. SFP 10G LR (Long Range):

   • Fiber Type:Designed for single-mode fiber (SMF).

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

   • Transmission Distance:Suitable for longer distances, generally up to 10 kilometers (about 6.2 miles).

   • Applications:Ideal for connections over longer distances such as campus networks, metropolitan area networks, or within large data centers.

In summary, the key differences are the types of fiber they are compatible with (multimode for SR and single-mode for LR), the wavelengths they operate at, and the distances they are capable of transmitting data over. The choice between SFP 10G SR and LR depends on the specific requirements of your network, particularly the distance over which data needs to be transmitted.
