In 2003, the OM3 fiber type was standardized and is closely linked to the IEEE 802. Multimode Fiber (MMF) has a core diameter, typically 50–100 micrometers, has ability to transfer multiple modes of light through the fiber core, uses lower-cost electronics (LED, VCSEL) operates at the 850 nm and 1300 nm wavelength and is used for short distance interconnections (up to 550m). This guide explains the five generations of multimode fiber - OM1, OM2, OM3, OM4, and OM5 - covering their physical characteristics, color coding, bandwidth, maximum distances at different data rates, optical sources (LED, VCSEL, SWDM), and real-world applications in enterprise networks and data. Multimode fiber (MMF) optic cable carries multiple light modes (rays) simultaneously through a larger core diameter, typically 50 μm or 62. This larger core allows easier light injection and lower-cost optical sources (LEDs and VCSELs), making multimode fiber the cost-effective choice for. Apart from the OM1 type, all of them are bending-optimized fiber incorporating technology to deliver enhanced macro-bending performance produced by a unique Plasma Chemical Vapor Deposition.
