Multimode fiber optic cable has a large-diameter core that is much larger than the wavelength of light transmitted, and therefore has multiple pathways of light-several wavelengths of light are used in the fiber core.
Multimode fiber optic cable can be used for most general fiber applications. Use multimode fiber for bringing fiber to the desktop, for adding segments to your existing network, or in smaller applications such as alarm systems. Multimode cable comes with two different core sizes: 50 micron or 62.5 micron.
What are 50 um fiber and 62.5 um fiber?
The numbers 50μm and 62.5μm refer to the diameters of the glass or plastic core, the part of the fiber that carries the light which encodes your data. The dimensions are sometimes specified as 50/125μm and 62.5/125μm, to include the diameter of the cladding. (The cladding confines the light to the core because it has a lower index of refraction.) Cable construction is shown in the following diagram, indicating the cable core, cladding, and outer jacket diameters.
The
Differences
Although 50-micron fiber features a smaller core, which is the light-carrying portion of the fiber, both 62.5- and 50-micron cable feature the same glass cladding diameter of 125 microns. You can use both in the same types of networks, although 50-micron cable is recommended for premise applications: backbone, horizontal, and intrabuilding connections, and should be considered especially for any new construction and installations. Both types can use either LED or laser light sources.
The main difference between 50-micron and 62.5-micron cable is in bandwidth-50-micron cable features three times the bandwidth of standard 62.5-micron cable, particularly at 850 nm. The 850-nm wavelength is becoming more important as lasers are being used more frequently as a light source.
Other differences are distance and speed. 50-micron cable provides longer link lengths and/or higher speeds in the 850-nm wavelength.

OM1 Multimode Fiber Cables: OM1 fiber has a bigger core diameter, it makes the OM1 fiber better ability on concentrating the light and bend-resistance. OM1 fiber optic patch cable are widely used especially before the mid 1990s and it became a standard multimode fiber in the U.S.A. OM1 fiber was the indoor cabling standard chosen by AT&T, ANSI and IBM. For OM1 fiber cable, the max attenuation is 3.5Db/km working at 850nm, 1.5dB/km at 1300nm. Overfilled launch of OM1 fiber optic cable at 850nm is 200MHz*km, at 1300nm is 500MHz*km. Today, OM1 fiber optic cables are still a popular indoor use multimode fiber optic cable. Fiberstore supply high quality OM1 fiber patch cables to ensure the performance and reliability of data storage, servers, and network switches. The fiber cables are with high return loss and low insertion loss, and they can be available in OM1 LC patch cable, OM1 SC patch cable, OM1 FC fiber patch cable, and other types of connector. These fiber cables are compatible with all major brands like Cisco, HP, Foundry and Juniper. We also provide OM1 fiber cables in Riser, Plenum, and LSZH (Low smoke - Zero Halogen) types.
OM2 Multimode Fiber Cables: OM2 fiber optic cable refer to the commonly used 50/125 traditional multimode fiber cable. OM2 is a standard for multimode cable defined by ISO/IEC 11801. OM1 and OM2 are both orange jacketed cable, and you cannot judge from the outer diameter to identify OM1 and OM2 fiber cable, because the 50/125 and 62.5/125 refer not to whole cable diameter but to the fiber inside. OM2 50/125 multimode fiber cables are used in fiber optic telecommunications and high speed transmission systems that require simultaneous, bi-directional data transfer. 50 µm fiber offers as much as ten times the bandwidth of 62.5 µm fiber. Our OM2 50/125 fiber patch cables can be available in simplex and duplex with FC, SC, LC, ST, MTRJ or MU connectors.
OM3 Multimode Fiber Cables: OM3 has a suggested jacket color of aqua. Like OM2, its core size is 50µm, but the cable is optimized for laser based equipment that uses fewer modes of light. As a result of this optimization, it is capable of running 10 Gigabit Ethernet at lengths up to 300 meters. Since its inception, production techniques have improved the overall capabilities of OM3 to enable its use with 40 Gigabit and 100 Gigabit Ethernet up to 100 meters. 10 Gigabit Ethernet is its most common use. Fiberstore offer a variety of OM3 fiber patch cables, there are OM3 simplex LC patch cable, OM3 SC patch cable, OM3 FC patch cable, OM3 fiber cable LC ST, and other types of OM3 fiber patch cable. All the cables are 100% optically tested for maximum performance before shipping worldwide.
OM4 Multimode Fiber Cables: OM4 fiber has been on the market since 2005, sold as premium OM3 or OM3 fiber. The OM4 designation standardizes the nomenclature across all manufacturers so that the customer has a clearer idea of the product that they are buying. OM4 is completely backwards compatible with OM3 fiber and shares the same distinctive aqua jacket. OM4 was developed specifically for VSCEL laser transmission and allows 10 Gig / second link distances of up to 550 Meters (compared to 300M with OM3). OM4 multi mode fiber optic cable is the highest level of multi-mode fiber optic cable that you can use. The om4 multi mode fiber cable has the highest bandwidth possible and therefore can be used in networks where an overwhelming or extreme amount of data transfers will take place.
