Multimode fiber optic cable, on the other hand, has a larger diameter core, typically 50 or 62. This larger core allows multiple modes of light to pass through, resulting in a wider beam of light and a shorter transmission distance. 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). Multi-mode fiber has a fairly large core diameter that enables multiple light modes to be propagated and limits the maximum length of a transmission link because of modal dispersion. 1 defines the most widely used forms of multi-mode optical fiber. This makes multimode fiber ideal for: Typical distance capabilities include: Multimode fiber pairs naturally with VCSEL-based transceivers, which are cheaper, consume less. There are five main types of multimode fiber, standardized by ISO/IEC 11801: OM1, OM2, OM3, OM4 and OM5. With several types available—OM1, OM2, OM3, OM4, and OM5—each offering distinct performance characteristics, selecting the right fiber can be.
