General characteristics of multimode fiber optic patchcords


Multimode MM patchcords composed with, among others, OM1, OM2, OM3 and OM4 fibers (nomenclature adopted according to IEC- International Electrotechnical Commission specifications). Available in duplex (dual-fiber) in 1m, 2m, 3m, 5m lengths.
Multimode Fiber (MMF) is characterized by a larger core diameter than single-mode fibers and is either 50 or 62.5 micrometers wide. In a multimode fiber, a wave of the same wavelength can propagate along multiple paths called mods, hence the name multimode fiber. The speed of movement of the mods along the waveguide can vary, causing distortion (blurring) of the pulse (mod dispersion), and thus limiting the transmission speed or transmission distance, which is why multimode fibers are used for short distances (e.g., within a building).

LightOptics multimode patchcords are high-quality duplex LC/UPC - LC/UPC optical fiber patchcord made of OM3 fiber. It is ISO9001, 14001 and ROHS certified. Equipped with LC / UPC type connectors on both ends (UPC - flat polished ferrule connector). It is used to connect end devices or network equipment to the structured cabling system.
