Although both 1000BASE-LX and 1000BASE-SX have the same data rate of 1 Gbps, the main difference lies in their transmission distance. The SX variant supports short-range transmissions of up to 550 meters over multimode fiber, making it suitable for LAN and campus network deployments. On the other hand, LX supports long-range transmissions of up to 10 km over single-mode fiber, making it ideal for wide-area network (WAN) and Metro Ethernet applications. Since both standards offer the same data rate, the choice will depend on the transmission distance you need. Therefore, if short-range transmission is sufficient, 1000BASE-SX would be the best choice, and if longer-range transmissions are required, 1000BASE-LX is the ideal option.
