Multimode fibers if used for long distances lead to dispersion and signal losses. So, the distance for these cables is usually restricted to 2 km. However, it is more commonly used for lower-speed applications, such as 100 Megabit Ethernet, in short-distance Ethernet setups like Local Area Networks (LANs) and. OM1 and OM2: Support distances up to 300 meters at 1 Gbps. OM3 and OM4: Can achieve 100 meters at 100 Gbps and 400 meters at 10 Gbps., 40G, 100G, 400G). Multimode fiber optic cables are designed to carry multiple light modes simultaneously, each taking a different path or mode through the fiber. This characteristic makes MMF ideal for high-bandwidth applications over relatively short distances. Compared with copper-based 100BASE-TX connections, it offers stronger EMI immunity, longer reach, and improved reliability in electrically noisy.
