OM2 (Optical Multimode 2) is a type of multimode optical fiber commonly used for short-distance communications within a data center or campus network. OM2 fiber is specified by the ISO/IEC and TIA/EIA standards to support Gigabit Ethernet (1 Gbps) and 10 Gigabit Ethernet (10 Gbps) applications. It has a core diameter of 50 µm and a modal bandwidth of 2000 MHz/km. Its main advantage. Likewise, OM2 fiber also comes with an orange jacket and uses a LED light source but with a smaller core size of 50 µm. For 10G applications, it is recommended to use OM3 or OM4 optical fiber, which have higher bandwidth and are designed to support higher data transmission. As we know, OM2 (50/125) multimode fibre is rated to 1Gbps by utilizing 850nm wavelength, and working distance up to 550 meters. If we do 10Gbps speeds, we can reach up to 82 meters on Multi-Mode OM2 cables. The question is – is it possible to achieve a longer distance over OM2 fibre with 10Gbps. With that in mind, let's look at the four main multimodal grades in use today.
