How many gigabits can an om4 fiber optic cable run
The maximum data rates supported by OM4 fiber include: 10 Gbps (Gigabits per second): OM4 fiber can support 10 Gbps over a distance of up to 550 meters. 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 gigabit Ethernet. With OM4 fiber, you can transmit a 10G Ethernet signal up to 400 meters, a 25G Ethernet signal up to 100 meters, a 40G Ethernet signal up to 150 meters, and a 100G Ethernet signal up to 70m OM3 and 100m OM4. Two of the most widely deployed laser-optimized multimode fibers are OM3 and OM4, both designed to support high-speed data transmission. While single-mode fiber (SMF) dominates long-distance and carrier-grade infrastructure, multimode fiber remains the most cost-efficient and practical choice for enterprise buildings, campus networks, and modern data centers.
