Performance
Mufananidzo 1. Mutakuri Kudzvinyirira
Mufananidzo 2. Pulse Generation
Mufananidzo 3. Modulator max simba
Mufananidzo 4. Modulator shoma simba
Maxim DC extinction ratio
Mukuedza uku, hapana masaini eRF akaiswa kuhurongwa.Pure DC extinciton yakayerwa.
1. Mufananidzo 5 unoratidza simba remaziso rekubuda kwemodulator, apo modulator inodzorwa paPeak point.Iyo inoratidza 3.71dBm mudhayagiramu.
2. Mufananidzo 6 unoratidza simba remaziso rekubuda kwemodulator, apo modulator inodzorwa paNull point.Inoratidza -46.73dBm mudhayagiramu.Mukuedza chaiko, kukosha kunosiyana kwakapoteredza -47dBm;uye -46.73 inokosha yakagadzikana.
3. Naizvozvo, yakatsiga DC kutsakatika reshiyo akayera 50.4dB.
Zvinodikanwa zvehuwandu hwekutsakatika kwepamusoro
1. System modulator inofanira kuva nepamusoro-soro yekutsakatika.Hunhu hwesystem modulator inosarudza iyo yakanyanya kutsakatika reshiyo inogona kuwanikwa.
2. Polarization yemwenje yekuisa modulator ichatarisirwa.Modulators anonzwa kune polarization.Polarization yakakodzera inogona kuvandudza kutsakatika kwechiyero pamusoro pe10dB.Mukuedza kweLab, kazhinji polarization controller inodiwa.
3. Vatariri vakarerekera vakakodzera.Mune yedu DC extinction ratio kuyedza, 50.4dB yekudzima reshiyo yawanikwa.Nepo dhetabheti yemodulator inogadzira inonyora 40dB chete.Chikonzero chekuvandudza uku ndechekuti mamwe ma modulators anokukurwa nekukurumidza.Rofea R-BC-ANY madhiraivha ekurerekera anovandudza bias voltage pasekondi imwe yega yega kuti ive nechokwadi chekukurumidza kupindura.

1. MER inoreva Modulator Extinction Ratio.Huyero hwekutsakatika hunowanikwa kazhinji chiyero chekutsakatika chemodulator chakatsanangurwa mune modulator dhatabheti.
2. CSO inoreva kuumbwa kwechipiri.Kuyera CSO nemazvo, iwo mutsara mhando yeRF siginecha, modulators uye vanogamuchira vanozovimbiswa.Uye zvakare, iyo system CSO kuverenga inogona kusiyana kana ichimhanya pane akasiyana maRF frequency.
