Kushanda
Mufananidzo 1. Kudzvinyirirwa Kwemutakuri
Mufananidzo 2. Kugadzirwa kwePulse
Mufananidzo 3. Simba guru reModulator
Mufananidzo 4. Simba shoma reModulator
Chiyero chekutsakatika kweMaxim DC
Mukuyedza uku, hapana masaini eRF akaiswa pasystem. Pure DC extinciton yakayerwa.
1. Mufananidzo 5 unoratidza simba re optical re modulator output, kana modulator ichidzorwa paPeak point. Inoratidza 3.71dBm mudhayagiramu.
2. Mufananidzo 6 unoratidza simba re optical re modulator output, kana modulator ichidzorwa paNull point. Inoratidza -46.73dBm mudhayagiramu. Mukuyedza chaiko, kukosha kunosiyana-siyana pa -47dBm; uye -46.73 inhamba yakagadzikana.
3. Saka, chiyero cheDC extinction chakayerwa i50.4dB.
Zvinodiwa kuti pave nehuwandu hwakawanda hwekutsakatika kweropa
1. System modulator inofanira kunge iine high disappency ratio. Hunhu hwesystem modulator hunosarudza kuti high disappency ratio inogona kuwanikwa.
2. Kugadziriswa kwechiedza che modulator kunofanira kugadziriswa. Ma modulator anonzwa kukanganiswa nekugadziriswa kwe polar. Kugadziriswa kwakakodzera kunogona kuwedzera chiyero chekutsakatika kwechiedza kupfuura 10dB. Mukuyedza kwerabhoritari, kazhinji muchina wekutonga kudzorwa kwechiedza unodiwa.
3. Vatongi vebias vakakodzera. Mukuyedza kwedu DC extinction ratio, 50.4dB extinction ratio yakawanikwa. Kunyange zvazvo datasheet yemugadziri wemodulator iine 40dB chete. Chikonzero chekuvandudzwa uku ndechekuti mamwe mamodulator anongomhanya nekukurumidza. Rofea R-BC-ANY bias controllers inogadzirisa bias voltage sekondi imwe chete kuti ive nechokwadi chekuti mhinduro inokurumidza.

1. Mamwe maMZ modulators ane ma photodiode emukati. Kugadzika kwemutongi kunofanirwa kusarudzwa pakati pekushandisa photodiode yemutongi kana kushandisa photodiode yemukati yemutongi. Zvinokurudzirwa kushandisa photodiode yemutongi pakuyedza kweLab nekuda kwezvikonzero zviviri. Chekutanga, photodiode yemutongi yakavimbisa kunaka. Chechipiri, zviri nyore kugadzirisa chinangwa chechiedza chekupinda. Cherechedza: Kana uchishandisa photodiode yemukati yemutongi, ndapota iva nechokwadi chekuti simba rekubuda kwephotodiode rinoenderana nesimba rekupinda.
2. Polar pin inoshandiswa kuchinja control point pakati pePeak neNull muNull control mode (inosarudzwa neMode Select pin) kana Quad+
uye Quad-in Quad control mode. Kana jumper yepolar pin isina kuiswa, control point ichave Null muNull mode kana Quad+ muQuad mode. Amplitude yeRF system ichakanganisawo control point. Kana pasina RF signal kana RF signal amplitude iri diki, controller inokwanisa kukiya work point kuti igadzirise point sezvakasarudzwa neMS nePLR jumper. Kana RF signal amplitude ikadarika threshold yakati, polar yesystem ichachinjwa, muchiitiko ichi, PLR header inofanira kunge iri mumamiriro akasiyana, kureva kuti jumper inofanira kuiswa kana isina kuiswa kana kudhonzwa kana yaiswa.
Kushandiswa Kwakajairika
Chinodzora chiri nyore kushandisa.
Danho 1. Batanidza 1% yekoupler kune photodiode yemutongi.
Danho rechipiri. Batanidza bias voltage output ye controller (kuburikidza neSMA kana 2.54mm 2-pin header) kune bias port ye modulator.
Danho rechitatu. Ipa controller voltages ye +15V uye -15V DC.
Danho rechina. Dzosera controller uye ichatanga kushanda.
CHERECHEDZA. Ndapota iva nechokwadi chekuti chiratidzo cheRF chesystem yese chakabatidzwa usati wagadzirisa controller.
