Abstract
PURPOSE:To prevent the titled device from the influence of reflected noise through simple configuration by fixing the length of a transmitting fiber between a laser diode and a capacitor on a half or less of the wavelength of a component having the maximum frequency of a transmission band. CONSTITUTION:If the length of a pig tail fiber 2 between a laser diode 1 and a capacitor 3 is regulated to a half or less of the wavelength of maximum frequency of a signal transmitted by the optical system, a peak component of reflected noises is located at the outside of a transmission band and does not exert the influence on the optical system. Thus, a transmission device prevented from the influence of reflected noises is produced through simple configuration.
