Multimode Fiber Types: OM1 vs OM2 vs OM3 vs OM4
OM3 supports 10 Gigabit Ethernet at lengths up to 300 meters. Besides, OM3 is able to support 40 Gigabit and 100 Gigabit Ethernet up to 100

Home / What does OM3 mean in multimode 10 Gigabit optical cable
Overview: OM3 is the laser-optimized 50 μm fiber (per TIA-492AAAC) specifically designed for VCSEL (Vertical-Cavity Surface-Emitting Laser) sources operating at 850nm. Its differential mode delay (DMD) characteristics ensure single-mode-like performance at 10G/40G/100G speeds. In the two tables above, we've summarized the main differences between OM1, OM2, OM3, OM4, and OM5. The next part will compare these fibers from the side of core size, bandwidth, data rate, distance, color and optical source in details. OM3 is for enhanced 50 micron glass (capable of 10 gigabit Ethernet out to 300m). Multimode fiber refers to a kind of optical fiber that is able to transmit many light modes at the same time, hence allowing multiple signals to be carried in the same fiber. This is made possible by using a bigger core diameter, often 50 micrometers, which allows data transmission over.
