Why are OM3 and OM4 multimode fibers popular in premises cabling systems?

• A. They are more affordable than other fibers
• B. They are "laser optimized" for better distance capability
• C. They have a larger core size
• D. They are resistant to environmental stress

Answer: (B)

OM3 and OM4 multimode fibers are popular in premises cabling systems primarily because they are "laser optimized," which means they are designed to support higher bandwidths and enable better performance over longer distances when using laser-based light sources, such as VCSELs (Vertical Cavity Surface Emitting Lasers). This optimization allows these fiber types to effectively manage modal dispersion and enhance the overall signal quality, making them suitable for applications that require high-speed data transmission. In essence, the laser optimization allows operators to achieve better performance and extend the range of data transmission, which is particularly important in environments with high data demands, like data centers or enterprise networks. This capability aligns well with the increasing need for both bandwidth and distance in modern networking, solidifying their standing as a preferred choice in the industry.
