| 英文摘要 | An optical signal-to-noise ratio (OSNR) monitor device includes an optical receiver including a delay interferometer, which divides a modulation signal in accordance with a given bandwidth and subjected to amplitude shift keying into two signals and causes the signals to interfere with each other, and optical detectors, which output currents in accordance with the optical signals output from the interferometer, and an amplifier that amplifies the currents output from the optical detectors so as to obtain predetermined current amounts; an optical power monitor configured to obtain the optical powers of the optical signals received by the optical detectors included in the optical receiver; and an OSNR calculator configured to calculate an optical signal-to-noise ratio in accordance with the optical powers obtained from the optical power monitor and a reception bandwidth. |
