Multimode fiber can carry 10 Gigabit Ethernet
In SMF light follows a single path through the fiber while in MMF it takes multiple paths resulting in differential mode delay (DMD). OM3, OM4, and OM5 are types of multi-mode optical fibres commonly used in data centres and enterprise environments to support various network speeds and transmission distances, including 10 gigabit Ethernet (10G), 40 gigabit Ethernet (40G), 100 gigabit Ethernet (100G) and 400. Today, it is being used in campus LAN premises applications such as 10GbE; specified in ISO/IEC 11801 and TIA/EIA-568 cabling standards. Due to larger core diameter and higher numerical aperture it couples more light from LED sources than 50/125 fiber.
