Is LX compatible with LH?
The answer is: Yes, 1000 BASE-LX SFP can work with 1000 BASE-LH SFP. For example, Cisco 1000 BASE LX/LH SFP is either made for single mode (long distance) or multimode (short distance). But this module can also be used for both single mode and multimode.
What does LX mean on SFP?
long wavelength The “LX” in 1000BASE-LX stands for long wavelength, indicating that this version of Gigabit Ethernet is intended for use with long-wavelength transmissions (1270–1355 nm) over long cable runs of fiber optic cabling.
What is LH in SFP?
LH refers to Long Haul. Many vendors use both of them for certain SFP modules, but they aren’t a Gigabit Ethernet standard at all. 1000BASE-LX/LH SFP can achieve a distance up to 20 km over single mode fiber. Unlike that, 1000BASE-LH SFP operates a distance up to 70 km over single mode fiber. Conclusion.

What is the difference between LX and LH SFP?
While 1000BASE-LH is only a term widely used by many suppliers. Besides, LH means longer distance, while LX (long wavelength) means shorter energy, which is obviously shorter distance. Unlike the 1000BASE-LX SFP module, 1000BASE-LH SFP module can operate at a distance up to 70km over single mode fiber.
Is LX single mode or multimode?
The 1000BASE-LX/LH SFP, compatible with the IEEE 802.3z 1000BASE-LX standard, operates on standard single- mode fiber-optic link spans of up to 10 km and up to 550 m on any multimode fibers.

What is SX and LX?
SX stands for short wavelength. The standard specifies a distance capability between 220 meters and 550 meters. 1000BASE-LX can run over both single mode fiber and multimode fiber with a distance of up to 10 km and 550 m, respectively.
How does an LX cable differ from an SX cable?
1000BASE-LX single-mode SFP module will work with single-mode fiber in order to perform both transmission and reception of data. Whereas 1000BASE-SX multimode SFP transceiver will work with multimode fiber, which has a thicker core and allows higher speed at shorter distance.
What SFP should I use?
When choosing SFP modules, you should consider whether it matches the switch port and the cable you have prepared. If you have multimode cable, then you can choose GLC-SX-MM 1000BASE SFP. If you use single-mode fiber cable, you should select GLC-LH-SM 1000BASE SFP.
