What is multimode cable?

Multimode fiber cables come in several types, categorized by core diameter and bandwidth capabilities. OM1 has a core diameter of 62.5 microns and supports Ethernet speeds up to 1 Gb/s over short distances. OM2, with a 50-micron core, offers improved bandwidth, suitable for Fast Ethernet and Gigabit Ethernet applications. OM3 and OM4, also 50-micron cores, are designed for higher speeds like 10 Gigabit Ethernet, with OM4 supporting longer distances at these speeds. OM5, a newer addition, supports multiple wavelengths for increased network capacity over extended distances, known as Wideband Multimode Fiber (WBMMF).
