title: Errors in single-mode cutoff wavelength measurements due to periodic features in the transmission spectrum of a short multimode reference fiber.
abstract: The transmission spectrum of a short multimode fiber can vary periodically with the reciprocal of wavelength. This adversely affects a standard EIA and CCITT measurement method for cutoff wavelength of single-mode fiber. The measurement problem may be solved by underfilling the multimode reference fiber. The periodic spectral characteristics resemble interference phenomena.
