Single-mode and multimode optical fibres are used in fibre optic communication systems. The diameter of the core, which impacts the number of light modes that can be broadcasted and the range over which the signal can be transferred, is the primary difference between the two. Read this article to find out more about Single-Mode Fiber and Multimode Fiber and how they are different from each other. What is Single-Mode Fiber? SMF stands for single-mode fiber. It can transmit only one mode of light because of its small core diameter. Single-mode fibres are used in cable television and backbone networks. It ... Read More
