Home / Attenuation of one kilometer of multimode fiber
Attenuation is a measure of the loss of signal strength or light power that occurs as light pulses propagate through a run of multimode or single-mode fiber. The attenuation coefficient is measured in decibels per kilometer (dB/km) and is determined by several factors, including the type of fiber used in the cable, the wavelength of the light, and the quality of the fiber and its connections. It is the fiber type the IEEE, ANSI, TIA, and ISO standards organizations typically define in fiber LAN specifications. Multimode fiber is large enough in diameter to allow rays of light to reflect internally (bounce off the walls of the fiber).
One kilometer is to some extent an arbitrarily chosen convention for comparing one optical fiber''s BW with another. Doubling the transmission distance does not necessarily reduce the BW by half.
