Electro-optical modulator and system thereof

[0057] Such as Figure 6 As shown, when the splitting ratio of the splitting component 320 is 1:2, the splitting component 320 can output two optical signals based on the splitting ratio, and the two optical signals can be input into the two modulating components 310 in a one-to-one correspondence, At this time, the modulation component 310 modulates the corresponding optical signal based on the obtained electrical signal and outputs two modulated optical signals, and then based on the multiple relationship between the attenuation values ​​between the attenuation components 330, two attenuation components 330 are used. , and their attenuation values ​​can be 3dB and 6dB respectively, and finally the two attenuated optical signals are transmitted to the optical signal output end 200, so that multi-order optical signals can be generated to match the optical fiber for signal transmission.

[0059] Such as Figure 7 As shown, when the splitting ratio of the splitting component 320 is 1:2, the splitting component 320 can output two optical signals based on the splitting ratio, and the two optical signals can be input into the two modulating components 310 in a one-to-one correspondence, At this time, the modulation component 310 modulates the corresponding optical signal based on the obtained electrical signal and outputs two modulated optical signals, and then only one attenuation component 330 is used, that is, only one of the modulated optical signals is attenuated, The other modulated optical signal is directly output to the optical signal output terminal 200 without attenuation. At this time, the attenuation value of the attenuation component 330 can be 3dB, and finally the attenuated optical signal and the unattenuated optical signal One optical signal is transmitted to the optical signal output end 200, so that a multi-stage optical signal can be generated to m

[0061] Such as Figure 8 As shown, when the splitting ratio of the splitting component 320 is 1:3, the splitting component 320 can output three optical signals based on the splitting ratio, and the three optical signals can be input into the three modulating components 310 in one-to-one correspondence, At this time, the modulation component 310 modulates the corresponding optical signal based on the obtained electrical signal and outputs three modulated optical signals, and then based on the multiple relationship between the attenuation values ​​between the attenuation components 330, three attenuation components 330 are used, The attenuation values ​​can be 3dB, 6dB and 9dB respectively, and finally the three attenuated optical signals are transmitted to the optical signal output port 200, so that multi-order optical signals can be generated to match the optical fiber for signal transmission.
