For 10 Gigabit Ethernet over OM2 fiber, the typical reach is up to 82 meters (approximately 269 feet). This reach is based on the standard OM2 fiber characteristics and the use of 850nm wavelength transceivers, which are common for multimode fiber applications. Modal dispersion, not signal attenuation, is what kills multimode distance. You can't fix it with a stronger laser or a better receiver. Your options are better fiber (OM4 over OM3), lower data rates, or. 10G multimode fiber (MMF) is a type of fiber optic cable that is capable of supporting 10 Gbps data transfer rates. It is designed for use in high-speed network applications and is typically used in data centers, enterprise networks, and other short distance applications. The type of optical source—LEDs or Vertical-Cavity Surface-Emitting Lasers (VCSELs)—significantly influences.
