Description of OM3 Fiber Patch Cords
"OM" stands for optical multi-mode, which is the standard for multimode optical fiber to indicate the fiber grade.
Comparison of OM1, OM2, OM3, and OM4 Fiber Parameters and Specifications
1. OM1 refers to 50µm or 62.5µm core multimode fiber with a full injection bandwidth of 200/500MHz/km or greater at 850/1300nm.
2. OM2 refers to 50µm or 62.5µm core multimode fiber with a full injection bandwidth of 500/500MHz/km or greater at 850/1300nm.
3. OM3 is an 850nm laser-optimized, 50µm core multimode fiber. In 10Gb/s Ethernet using an 850nm VCSEL, the fiber can transmit up to 300m.
4. OM4 is an upgraded version of OM3 multimode fiber, with a transmission distance of up to 550m.

FAQ
When should I use OM3 Fiber Patch Cords?
OM3 fiber is designed for use with VCSELs. It complies with the ISO/IEC 11801-2nd OM-3 fiber specification and meets the requirements of 10 Gigabit Ethernet applications. OM3 fiber comes in a variety of types, including indoor and indoor/outdoor options, with fiber counts ranging from 4 to 48 fibers. It also supports all applications based on legacy multimode 50/125 fiber, including LED and laser light sources.
1. OM3 fiber systems can extend the transmission distance of Gigabit Ethernet up to 900 meters, eliminating the need for expensive laser components for inter-building distances exceeding 550 meters.
2. Standard 62.5/125μm multimode fiber can be used for all applications within the OC-12 (622 Mb/s) speed range within a 2000-meter range. For all other scenarios, single-mode fiber is used. However, the emergence of OM3 multimode fiber has changed this situation. Because OM3 fiber can extend the transmission distance of Gigabit and 10 Gigabit systems, using 850nm wavelength optical modules in conjunction with VCSELs will be the most cost-effective cabling solution.
3. When link lengths exceed 1000 meters, single-mode fiber is still the only option. Single-mode fiber can achieve a transmission distance of 5 kilometers at a 1310nm wavelength in Gigabit systems and 10 kilometers in 10 Gigabit systems.
4. When link lengths are less than or equal to 1000 meters, OM3 50μm multimode fiber can be used in Gigabit systems, while single-mode fiber should be used in 10 Gigabit systems.
5. When link lengths are less than 300 meters, OM3 Fiber Patch Cords can be used in all Gigabit and 10 Gigabit systems.
