Filed: 1995-09-22
Abstract: PROBLEM TO BE SOLVED: To readily measure a CNR characteristic (noise characteristic) of an optical transmission apparatus with respect to the change of a relative intensity noise(RIN) characteristic of the optical transmission apparatus. SOLUTION: In a noise characteristic measuring device of an optical transmission apparatus, an output light from an optical transmission device 2 which is direct- intensity-modulated by a sine wave signal is allowed to enter a light receiving device 6 so that an intensity of a sine wave signal component of the output signal of the light receiving device 6 and an intensity of a noise component of a frequency in the vicinity of the sine wave signal are measured. A light amplifier device 4 using an erbium-doped fiber and variable light ATTs (attenuators) 3, 5 disposed in front of and rear the device 4 are provided between the optical transmission device 2 and light receiving device 6. An attenuation quantity of the previous variable light ATT 3 is adjusted so that an input optical level of the light amplifier device 4 is changed.  Incident lights each having different RIN characteristic is allowed to enter the light receiving device 6 to measure a CNR characteristic by utilizing the fact that RIN of the output light is changed along the change of the incident light of the light amplifier device 4.
