OM2 fiber optic patch cords use standard multimode fiber. OM3 fiber patch cords, on the other hand, are a laser-optimized multimode fiber (LOMMF), designed specifically for use with 850 nm serial laser (VCSEL) sources, significantly reducing intermodal dispersion and improving. Within the multimode fiber family, OM2 and OM3 fiber optic patch cords are two common types, but they differ significantly in performance, applications, and cost-effectiveness. As far as i know, they are the same diameter of 50µm, they only have different bandwith caracteristics. Is there any other reason to don't do that? (except for the orange/aqua mess in the racks ;)) Apart from the functionality. ISO/IEC 11801 defines the OM1, OM2, OM3, OM4, and OM5 types of multimode fiber. There also are four types of multimode fiber identified by the “OM” (optical multi-mode) designation described by the ISO/IEC 11801 and they are: OM1, OM2, OM3 and OM4. OM4's superior bandwidth (4700 MHz·km) and 400-meter reach for 100G-SR4 enabled the provider to eliminate bottlenecks without a full singlemode retrofit. While OM2 offers improved performance, it is becoming.
