In this information age, optical fiber communication, as a high-speed, high-bandwidth data transmission method, has become an important cornerstone of modern communication networks. In optical fiber communication systems, multimode optical fiber is favored because of its suitability for short-distance transmission and relatively low cost. This article will take you through the different standards in fiber patch cord multimode, especially OM1, OM2, OM3, OM4 and OM5, and reveal the differences between them and their respective application scenarios.

In the selection of optical fiber, should pay attention to the tensile strength and heat resistance of optical fiber. Fiber optic tensile strength is generally 50N or higher, heat resistance requirements should be able to withstand -20 ° C to 60 ° C within forty hours of temperature change.
