What are OM3 and OM4 multimode fibers commonly referred to as?

OM3 and OM4 multimode fibers are commonly referred to as laser optimized multi-mode fibers. This designation stems from their design, which allows for the efficient transmission of signals over longer distances at higher data rates when used with specific light sources, like lasers.

These fibers have specific core diameters and optimized refractive index profiles that enhance their performance with laser-based transmission, minimizing modal dispersion, which is critical for maintaining signal quality in high-speed networks. This optimization makes them particularly suitable for modern applications such as data centers and enterprise networks, where high bandwidth and long distances are required.

The other terms listed do not accurately describe OM3 and OM4 fibers. Legacy multi-mode fibers typically refer to older multimode fiber types, while G.652 low water peak fiber and non-zero dispersion shifted fiber relate to specific single-mode fiber types, which are not applicable to the multimode context of OM3 and OM4.
