What are the differences in application between OM3 fiber and OM4 fiber?

2025-05-21

Latest company case about What are the differences in application between OM3 fiber and OM4 fiber?
OM3 fiber is a 50um core - diameter multimode fiber optimized for 850nm laser. It can reach a transmission distance of up to 300m in a 10Gb/s Ethernet network, making it suitable for medium - distance, high - speed data transmission scenarios in data centers, such as short - range connections between switches and servers. OM4 fiber, as an upgraded version of OM3, extends the transmission distance to 550m at 10Gb/s Ethernet. It also has more than twice the effective bandwidth of OM3, which means it can better support higher - speed applications like 40G and 100G Ethernet over longer distances within data centers, and is ideal for scenarios where longer transmission distances and higher bandwidths are required.
