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. 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. Definition: Multimode fiber has another name the “ Multi-Mode Optical Fiber “. It is especial type of optical fiber that designed for carrying multiple light beams or modes simultaneously, every at a marginally different reflection angle internal the optical fiber core. Multimode fiber optic cable has a larger core, typically 50 or 62.
