What is the overfilled launch (OFL) bandwidth of an OM1 multimode fiber at 850nm?

The overfilled launch (OFL) bandwidth of OM1 multimode fiber at 850nm is indeed 200 MHz-km, which is considered the standard measurement for this type of fiber. This bandwidth is crucial for determining the signal capacity and transmission distance of the fiber optic cable.

OM1 fiber, which has a core diameter of 62.5 microns, is designed to support high-speed data transmission over shorter distances. The 200 MHz-km value indicates that the fiber can effectively transmit signals with a frequency of 200 megahertz over a distance of one kilometer. This measurement signifies the ability of the fiber to handle data rates while minimizing signal degradation.

Other values represented in the options reflect the capabilities of fibers with different specifications or core sizes. However, OM1 specifically has been established and tested to yield a maximum OFL bandwidth of 200 MHz-km at the 850nm wavelength. This attribute of OM1 multimode fiber makes it suitable for various applications, especially in local area networks (LANs) and data communications where high bandwidth within limited distances is essential.
