The value numerically equal to the lowest frequency at which the magnitude of the base band transfer function of optical fiber decreases to a specified fraction generally to –3dB optical (-6dB electrical) of the zero frequency value.
The band width of an optical fiber is limited by several mechanisms, mainly by chromatic dispersion. Fiber band width is usually characterized in the time-domain as pulse broadening or more technically as dispersion.
