The bandwidth of an OM2 multimode fiber is _____ MHz-km at 1300 nm.

The bandwidth of OM2 multimode fiber at a wavelength of 1300 nm is specifically defined to be 500 MHz-km. This specification is crucial because it indicates the capacity of the fiber to carry data. Higher bandwidth means that the fiber can transmit more data over a given distance without losing signal integrity.

At 1300 nm, OM2 multimode fibers are optimized to utilize the modal dispersion characteristics effectively, allowing for higher data transmission rates compared to lower bandwidth fibers. The 500 MHz-km rating reflects the performance standard for OM2, making it suitable for various applications requiring moderate to high data rates over short to medium distances in network designs.

Understanding these specifications helps in selecting the appropriate fiber type for specific networking needs, ensuring that the chosen fiber can meet the performance requirements of the intended application.
