Mashandisirwo ekushandisaModulator yeEO
Mushure mekugamuchira EO modulator uye kuvhura pasuru, ndapota pfekai magirovhosi emagetsi/mabhande emaoko kana muchibata chikamu chesimbi chemudziyo. Shandisai tweezers kubvisa ma "optical input/output ports" emudziyo kubva muma "grooves" ebhokisi, uye mobvisa muviri mukuru wemodulator kubva muma "sponge grooves". Wobva wabata muviri mukuru weEO modulator neruoko rumwe wodhonza "optical input/output port" yemodulator nerumwe.
Kugadzirira uye kuongorora usati washandisa
a. Cherechedza kuti hapana kukuvara pamusoro pechigadzirwa, pamusoro pemodule uye sleeve yefiber ye optical.
b. Tarisa kuti label yacho haina tsvina uye kuti zviratidzo zvekudhinda zvesiriki-screen zvakajeka.
c. Flange yemagetsi haina kukuvara uye mapini ese eelectrode haana kukuvadzwa.
d. Shandisa chinhu chinoona magumo e optical fiber kuti uone kana optical fibers dziri kumativi ese dzakachena.
1. Matanho ekushandisamodulator yesimba
a. Tarisa kana magumo emagetsi ekuisa/kuburitsa emuchina we intensity modulator akachena. Kana paine mavara, ndapota apukute nealcohol.
b. Modulator yesimba imhando ye polarization-retaining input. Zvinokurudzirwa kushandisa polarization-retaining light source kana uchiishandisa (wavelength yechiedza inobva pawavelength inoshanda yemodulator), uye simba rechiedza chechiedza rinonyanya kukosha i10dBm.
Paunenge uchishandisa strength modulator, batanidza GND yemagetsi kune pin 1 yemodulator, uye positive terminal yemagetsi kune pin 2. Pin 3/4 ndiyo cathode uye anode yePD iri mukati memodulator. Kana uchida kuishandisa, ndapota shandisa iyi PD ine acquisition circuit iri kumashure, uye iyi PD inogona kushandiswa pasina kushandisa voltage (kana modulator isina PD yemukati, pin 3/4 iNC, pin yakamiswa).
d. Chinhu chiri mu intensity modulator inonzi lithium niobate. Kana magetsi ashandiswa, refractive index yekristaro inochinja. Saka, kana voltage ikashandiswa pamodulator, kurasikirwa kweinsertion yemodulator kunosiyana zvichienderana nevoltage inoshandiswa. Vashandisi vanogona kudzora modulator pane imwe nzvimbo yekushanda zvichienderana nekushandiswa kwayo.
Zvekungwaririra
a. Kupinza kwe optical kwe modulator hakufanirwe kudarika kukosha kwe calibration pa test sheet; zvikasadaro, modulator ichakuvara.
b. RF input yemodulator haifanirwe kudarika calibrated value iri pa test sheet; zvikasadaro, modulator ichakuvara.
c. Voltage yakawedzerwa yepini ye modulator bias voltage ndeye ≤±15V
2. Matanho ekushandisamodulator yechikamu
a. Tarisa kana magumo emagetsi ekuisa/kuburitsa emuchina we intensity modulator akachena. Kana paine mavara, ndapota apukute nealcohol.
b. Phase modulator inzira yekuchengetedza polarization. Zvinokurudzirwa kushandisa polarization-kuchengetedza chiedza kana uchichishandisa (wavelength yechiedza inobva pawavelength inoshanda yemodulator), uye simba rechiedza chechiedza rinonyanya kukosha i10dBm.
c. Paunenge uchishandisa phase modulator, batanidza chiratidzo cheRF kune RF input port yemodulator.
d. Phase modulator inogona kushanda mushure mekuwedzera chiratidzo cheredhiyo, ichipedzisa chikamu chachomodulator yemagetsi-opticChiedza chakagadziriswa hachigone kuonekwa zvakananga ne photodetector se modulated radio frequency signal. Kazhinji, interferometer inofanira kuiswa, uye radio frequency signal inogona kuonekwa chete ne photodetector mushure mekupindira.
Zvekungwaririra
a. Kupinza kweEO modulator hakufanirwe kudarika kukosha kwekuenzanisa papepa rekuyedza; zvikasadaro, modulator ichakuvara.
b. RF input yeEO modulator haifanirwe kudarika calibrated value iri pa test sheet; zvikasadaro, modulator ichakuvara.
c. Pakugadzika interferometer, pane zvinodiwa zvakanyanya zvekushandisa. Kuzununguka kwezvakatipoteredza uye kuzununguka kwefiber ye optical zvinogona kukanganisa mhedzisiro yebvunzo.
