What is the overfilled launch (OFL) bandwidth of an OM2 multimode fiber at 850 nm?

The overfilled launch (OFL) bandwidth of an OM2 multimode fiber at 850 nm is indeed 500 MHz-km. This specification is critical in determining the fiber's performance and capacity for transmitting data over distance. The OFL bandwidth value represents how many megahertz of bandwidth can be transmitted over a kilometer of fiber, and it is an important parameter for assessing the fiber optics’ ability to support high-speed applications.

OM2 fibers are designed specifically for multimode applications at shorter wavelengths, such as 850 nm, often used with LED light sources. The 500 MHz-km rating reflects the design and quality characteristics of the OM2 standard, balancing performance against cost and installation practicality for typical networking environments. Recognizing these specifications is essential for ensuring that the chosen fiber meets the throughput needs of the network and operates efficiently over the desired distance.
