OM3 fiber is an optical fiber designed to work with VCSELs. It conforms to the OM-3 fiber specification of ISO/IEC11801-2nd and meets the needs of 10 Gigabit Ethernet applications. There are many types of OM3 optical fibers, including indoor type, indoor/outdoor versatility, etc. The number of cores of the optical fiber ranges from 4 cores to 48 cores. All legacy multimode 50/125 fiber based applications are also supported, including support for LED light sources and laser light sources.
1. The transmission distance of Gigabit Ethernet using OM3 fiber system can be extended to 900 meters, which means that users do not need to use expensive laser devices when the distance between buildings exceeds 550 meters.
2. Within a distance of 2000 meters, standard 62.5/125μm multimode fiber can be used in various situations within the OC-12 (622Mb/s) rate range, and single-mode fiber will be used in other cases. However, the emergence of OM3 multimode fiber has changed this situation. Since OM3 fiber can increase the transmission distance of Gigabit and 10 Gigabit systems, the use of 850nm wavelength optical modules and VCSELs will be the most cost-effective wiring solution.
3. When the link length exceeds 1000 meters, single-mode fiber is still the only choice at present. Single-mode fiber can achieve a transmission distance of 5 kilometers at 1310nm wavelength in a gigabit system and 10 kilometers in a 10-gigabit system. Transmission distance.
4. When the link length is less than or equal to 1000 meters, OM3 50μm multimode fiber can be used in the gigabit system, and single-mode fiber should be used in the 10G system.
5. When the link length is less than 300 meters, OM3 multimode fiber can be used in any Gigabit and 10 Gigabit systems.
