OM2 is a 62.5/125 μm or 50/125 μm multimode fiber (MMF) tailored for short-distance data transmission, supporting up to 10Gbps over 300m (50/125 μm) or 220m (62.5/125 μm) with moderate effective modal bandwidth and low attenuation. It is commonly used in legacy enterprise LANs, campus networks, and older data centers, providing a reliable, cost-effective solution for short-haul connectivity that aligns with traditional multimode infrastructure requirements.
