title: Measurement of higher-order mode attenuation in single-mode fibers: effective cutoff wavelength.
abstract: A technique for the determination of the wavelength-dependent attenuation coefficient of the LP(11) mode in sing]emode fibers is presented. Knowledge of the magnitude of this coefficient is required, e.g., for the quantitative prediction of modal noise in an optical-fiber communication system. An effective cutoff wavelength of the LP(11) mode can be unambiguously defined as the wavelength at which the attenuation coefficient equals a specified value.
