Comparison of OM1, OM2, OM3, and OM4
1. OM1 refers to multimode optical fibers with a core diameter of 850/full injection bandwidth exceeding 200/. km for 5 Oum or 62.5um fibers;
2. OM2 refers to multimode optical fibers with a core diameter of 850/full injection bandwidth exceeding 500/. km for 50um or 62.5um fibers;
3. OM3 is a 50um core diameter multimode fiber optimized for 850nm laser. In 10Gb/s Ethernet using 850nm VCSEL, the fiber optic transmission distance can reach 300m;
4. OM4 Fiber Patch Cords is an upgraded version of OM 3 multimode fiber, with fiber transmission distances up to 550 meters.
Applications of OM1, OM2, OM 3, and OM 4 Fibers
1. OM1 and OM2 have been widely deployed in building applications for many years, supporting up to 1GB Ethernet transmission;
2. OM3 and OM4 optical cables are typically used in data center cabling environments, supporting high-speed Ethernet transmission of 10G or even 40/100G.

FAQ
Q: What is the difference between OM5 fiber optic patch cords and OM4 Fiber Patch Cables?
Structurally, the OM5 fiber optic patch cord is no different from the OM4 fiber optic patch cord, and the OM5 fiber optic patch cord is compatible with the OM4 fiber optic patch cord. In addition, there are still differences between the two. Below is a comparison between OM5 fiber optic patch cords and OM4 fiber optic patch cords.
Color difference: The outer sheath color of OM5 fiber optic jumper is aqua green; The outer sheath color of the OM4 fiber optic jumper is water blue.
Different wavelengths: The wavelength of OM5 fiber optic jumpers is generally 850/1300nm, which can support at least four wavelengths at a time; The wavelength of OM4 fiber optic jumpers is generally 850/1310nm, and can only support one wavelength at a time.
Different transmission distances: Under the same wavelength, the transmission distance of OM5 fiber optic jumpers is generally longer than that of OM4 fiber optic jumpers.
Different transmission rates: The transmission rates of OM5 fiber optic jumpers are 40Gb/s and 100Gb/s; The transmission rates of OM4 fiber optic patch cords are 10Gb/s, 40Gb/s, and 100Gb/s.
The effective mode bandwidth (EMB) is different: at a wavelength of 850nm, the effective mode bandwidth (EMB) of OM5 fiber patch cords is 6000MHZ.km, while the effective mode bandwidth (EMB) of OM4 fiber patch cords is 4700MHZ.km. Therefore, the effective mode bandwidth (EMB) of OM5 fiber patch cords is much higher than that of OM4 fiber patch cords.
