Today, I would like to introduce to you the common SFP optical modules: 1000BASE-SX, 1000BASE-LX, 1000BASE-EX, 1000BASE-ZX and 1000BASE-T. Which optical module is the representative of these five transmission media standards? What are the differences between 1000BASE-LX, 1000BASE-LH and 1000BASE-LX/LH SFP optical modules? Yi Tianguang Communication (etulink) will answer for you in detail in this article.

The following table introduces the differences among 1000BASE-SX, 1000BASE-LX, 1000BASE-EX, 1000BASE-ZX and 1000BASE-T SFP optical modules from four aspects: optical fiber type, central wavelength, transmission distance and interface.

The difference between 1000BASE-LH and 1000BASE-LX/LH SFP Optical Modules

LH refers to long distances, and unlike 1000BASE-LX, 1000BASE-LH and 1000BASE-LX/LH are not Gigabit Ethernet standards, but there are still many vendors using LH and LX/LH in SFP optical module models. The 1000BASE-LX/LH SFP optical module can reach the transmission distance of 10km through the single-mode fiber, while the transmission distance of the 1000BASE-LH SFP optical module on the single-mode fiber can reach 70km.

In addition, the SFP optical module supplied by Yi Tianguang Communication has the advantages of high performance-to-price ratio, good compatibility, stable signal transmission, anti-plugging and so on, as well as professional technical support and solutions; Yi Tianguang Communication-helps you build your network easily.

Recommendation of SFP Optical Module for easy Sky Optical Communication

Suggestion: short-distance transmission scheme choose multimode optical module (550m~2km) or electric port module, long-distance transmission scheme can choose single-mode optical module (2km~160km). For more exciting content, please follow Yi Tianguang Communication official website, thank you!
