First, the transmission distance is different1, om4 fiber: om4 fiber in 1G, version 10G, 40G/100G state of the maximum transmission distance of 1km, 550m, 150m.
2, om3 fiber: om3 fiber in 1G, 10G, 40G/100G state of the maximum transmission distance of 1km, 300m, 100m.
Second, different production costs
1, om4 fiber: om4 fiber due to high transmission bandwidth requirements, resulting in higher production costs.
2, om3 fiber: om3 fiber due to low transmission bandwidth requirements, production demand, making the production cost lower.
Third, the use of different
1, om4 fiber: om4 fiber optic applications right in the high-speed network, suitable for data centers, financial centers and enterprise parks.
2, om3 fiber: om3 fiber used in short-range networks, local area networks (LAN) and private networks.
The real difference between OM3 and OM4 multimode fiber is that OM4 has a higher mode bandwidth - 4700 MHz-km compared to 2000 MHz-km for OM3 fiber. this means that OM4 fiber can transmit more information over the same distance. the main difference between M3 and OM4 multimode fiber is the internal structure of the fiber core. The main difference between M3 and OM4 multimode fibers is the internal construction of the core.
Both types of fibers are laser-optimized 50/125 multimode fibers, which means that both have a core diameter of 50 µm and a cladding diameter of 125 µm, which is specially clad to prevent light leakage from the core. Both fibers use the same connector, the same termination, and the same transceiver, a vertical cavity surface emitting laser (VCSEL), which emits infrared light at a wavelength of 850 nm.The main difference between OM3 and OM4 multimode fibers is the internal construction of the core.
