What is the main advantage of using OM3 multimode fiber over OM2?

The main advantage of using OM3 multimode fiber over OM2 is the higher bandwidth. OM3 fiber is specifically designed for high-speed, high-capacity applications, which supports a larger number of channels and higher data transmission across longer distances. This is primarily due to its larger core size and improved light-carrying capabilities, allowing for better performance in modern data transmission needs, particularly with 10 Gigabit Ethernet and beyond.

In contrast, OM2 multimode fiber was designed primarily for lower-speed applications and has limitations when it comes to supporting higher bandwidths, especially as network demands increase. This makes OM3 a better choice in environments where increased capacity and speed are critical for system performance. The advancements in OM3 fiber not only allow it to carry more data but also do so with better integrity over longer distances, making it the preferred option for contemporary networking infrastructures.
