    • An optical transmission device improved in quality and reliability of OADM function and permitting configuration of highly-flexible, economical OADM networks. A wavelength tunable filter variably selects a wavelength according to a control frequency. A filter controller applies the control frequency to the filter while scanning wavelength over an entire signal bandwidth, to detect, from a reference wavelength monitor signal supplied thereto, a reference control frequency which permits the filter to select a reference wavelength and according to which wavelength is matched. On receiving a wavelength selection request, the controller obtains a target control frequency from the reference control frequency and the position of a target wavelength relative to the reference wavelength, and applies the obtained frequency to the filter. A reference wavelength filter transmits the reference wavelength therethrough. A light-receiving element monitors the transmitted reference wavelength to generate the monitor signal.

    • A drop-type AOTF is used as a configuration for removing from a through signal an optical signal having the same wavelength as that of an optical signal to be added. To the drop-type AOTF, RF signals are input to always select all of wavelengths, and an RF signal is not input for a wavelength desired to be rejected. As a result, the optical signal having the wavelength for which the RF signal is stopped is not selected by the drop-type AOTF, and cannot pass through. Since there is only one RF signal whose input is stopped, a “drawing effect” does not occur, and control of an optical add/drop device is simplified. Additionally, since high-speed switching can be made, and a wavelength to be added can be varied, restrictions are not imposed on a network configuration.
    • 使用液滴型AOTF作为从通过信号去除与要添加的光信号的波长相同的波长的光信号的配置。 对于放大型AOTF,输入RF信号以始终选择所有波长,并且不输入要被拒绝的波长的RF信号。 结果,具有停止RF信号的波长的光信号不被滴型AOTF选择,不能通过。 由于只有一个RF信号的输入停止,所以不会产生“绘图效果”,简化了光学分插装置的控制。 此外,由于可以进行高速切换,并且可以改变要添加的波长,所以不对网络配置施加限制。
