What is the maximum attenuation at 1300nm for multimode optical fiber cable (OM1 - OM5)?

The maximum attenuation at 1300nm for multimode optical fiber cable, including OM1 through OM5, is indeed established at 1.5 dB/km. This value is significant because it indicates the maximum loss of signal strength per kilometer due to the inherent properties of multimode fibers at this wavelength.

Understanding this specification is crucial for network design and fiber optic installations because it directly impacts the distance over which data can be reliably transmitted without significant signal loss. Multimode fibers, particularly in a enterprise network setting, are preferred for shorter distances and higher speeds, making this attenuation specification an important consideration when determining the layout and performance expectations of a fiber optic network.
