The key difference between 1000BASE-SX SFP and 1000BASE-LX SFP lies in their wavelength, transmission distance, and fiber type. Here's a comparison,
1. Wavelength and Transmission Medium
1000BASE-SX SFP: Uses a short-wavelength (850nm) laser and is designed for multimode fiber (MMF).
1000BASE-LX SFP: Uses a long-wavelength (1310nm) laser and supports both single-mode fiber (SMF) and multimode fiber (MMF).
2. Transmission Distance
1000BASE-SX SFP
● Supports up to 550m over OM2 multimode fiber.
● Typically used for short-range connections within a data center or enterprise LAN.
1000BASE-LX SFP
● Supports up to 20km over single-mode fiber.
● Can also work with multimode fiber (MMF) up to 550m with a mode-conditioning patch cord.
3. Application Scenarios
● 1000BASE-SX SFP is mainly used for short-range connections inside buildings, data centers, and campus networks.
● 1000BASE-LX SFP is designed for longer distances, such as metro networks, enterprise backbones, and fiber-to-the-building (FTTB) applications.
4. Compatibility
● Both modules use SFP (Small Form-factor Pluggable) interfaces and support Gigabit Ethernet (1GbE).
● If using 1000BASE-LX SFP on multimode fiber, a mode-conditioning patch cord (MCP) is required to prevent signal distortion.
If you need short-distance (≤550m) transmission over multimode fiber, go for 1000BASE-SX SFP. If you need long-distance (up to 20km) over single-mode fiber, choose 1000BASE-LX SFP.
