What are the types of multimode fiber optic cables

Multimode fiber optic cables are classified into several types, including OM1, OM2, OM3, OM4, and OM5, each designed for specific applications and performance requirements.Overview of Multimode Fiber TypesOM1 Fiber:Core Size: 62.5 µmMaximum Distance: Up to 33 meters for 10 Gigabit Ethernet; typically used for 100 Megabit Ethernet applications.Jacket Color: OrangeLight Source: LEDBandwidth: 200 MHz·km at 850 nm .OM2 Fiber:Core Size: 50 µmMaximum Distance: Up to 82 meters for 10 Gigabit Ethernet; commonly used for 1 Gigabit Ethernet applications.Jacket Color: OrangeLight Source: LEDBandwidth: 500 MHz·km at 850 nm .OM3 Fiber:Core Size: 50 µmMaximum Distance: Up to 300 meters for 10 Gigabit Ethernet; supports 40 Gigabit and 100 Gigabit Ethernet up to 100 meters.Jacket Color: AquaLight Source: Laser-optimized for VCSELs (Vertical-Cavity Surface-Emitting Lasers).Bandwidth: 2000 MHz·km at 850 nm .OM4 Fiber:Core Size: 50 µmMaximum Distance: Up to 400 meters for 100 Gigabit Ethernet; optimized for high-speed data transmission.Jacket Color: AquaLight Source: Laser-optimized.Bandwidth: 4700 MHz·km at 850 nm .OM5 Fiber:Core Size: 50 µmMaximum Distance: Similar to OM4 but designed to support multiple wavelengths on a single fiber using SWDM (Short Wavelength Division Multiplexing) technology.Jacket Color: Lime GreenLight Source: Laser-optimized.Bandwidth: 4000 MHz·km at 850 nm .ApplicationsData Centers: Multimode fibers are widely used in data centers for short-distance, high-bandwidth applications.Local Area Networks (LANs): Ideal for interconnecting devices within the same building or campus.Backbone Networks: Used for connecting different parts of a network within a limited distance.ConclusionChoosing the right type of multimode fiber optic cable depends on the specific requirements of your application, including distance, bandwidth, and the type of equipment being used. OM3 and OM4 are currently the most commonly deployed types in modern networks, while OM1 and OM2 are becoming less common due to their limited performance capabilities .
