摘要： In an OADM system, an OADM device includes an AOTF. The AOTF can select an optional wavelength by changing the frequency of an RF signal to be applied. An optical signal having a specified wavelength can be dropped from a wavelength-multiplexed optical signal input from an input terminal, or a wavelength-multiplexed optical signal input from an add port can be multiplexed with a through optical signal. However, considering the increase in coherent cross talk, the AOTF should be exclusively used for dropping in an actual device configuration. Otherwise, a drop optical signal is branched by an optical coupler with the wavelength selected by a tributary station. Thus, the wavelength selected by the tributary station can be extracted by the AOTF from the through optical signal.

摘要翻译： 在OADM系统中，OADM设备包括AOTF。 AOTF可以通过改变要施加的RF信号的频率来选择可选的波长。 具有指定波长的光信号可以从输入端输入的波分复用光信号中丢弃，或从加入口输入的波分复用光信号可以与通过光信号复用。 然而，考虑到相干串扰的增加，AOTF应该专门用于实际的设备配置。 否则，分支光信号由具有由分支站选择的波长的光耦合器分支。 因此，辅助站选择的波长可以由AOTF从通过光信号提取。

摘要： A configuration of acousto-optical tunable filters (AOTF) having stable output characteristics so that the output does not significantly vary with time. The configuration includes a plurality of AOTFs cascaded together. Each AOTF generates a surface acoustic wave in an optical waveguide in accordance with RF signals applied to the AOTF. A phase of a beat generated by the RF signals applied to one of the plurality of AOTFs is different from a phase of a beat generated by the RF signals applied to a different AOTF of the plurality of AOTFs.
