Nzira yekushandisa seiEO modulator
Mushure mekugamuchira iyo EO modulator uye kuvhura pasuru, ndapota pfekai magirovhosi emagetsi / mabhendi emaoko paunenge uchibata simbi chubhu shell chikamu chemudziyo. Shandisa ma tweezers kuti ubvise optical input/output ports dzemudziyo kubva mumigero yebhokisi, wobva wabvisa muviri mukuru wemodulator kubva mumigero yesiponji. Wobva wabata muviri mukuru weEO modulator nerumwe ruoko wokweva optical input/output port yemodulator neimwe.
Kugadzirira uye kuongorora kusati kwashandiswa
a. Cherechedza kuti hapana kukuvadza kune chigadzirwa chepamusoro, module yepamusoro uye optical fiber sleeve.
b. Tarisa kuti label yacho haina tsvina uye masikirini edhinda masikirini akajeka.
c. Iyo flange yemagetsi haina kukuvadzwa uye ese mapini e electrode akasimba.
d. Shandisa optical fiber end face detector kuti uone kana mafiber optical kumagumo ese akachena.
1. Matanho ekushandisaintensity modulator
a. Tarisa uone kana zviso zvekupedzisira zvekupinza / kubuda optical fibers ye intensity modulator yakachena. Kana paine mavara, ndapota pukuta iwo akachena nedoro.
b. Iyo intensity modulator ndeye polarization-inochengetedza yekuisa. Inokurudzirwa kushandisa polarization-inochengetedza mwenje sosi kana ichishandiswa (wavelength yemwenje sosi inotsamira pane inoshanda wavelength yemodulator), uye simba rechiedza rechiedza sosi rinonyanya 10dBm.
Paunenge uchishandisa simba rekugadzirisa simba, shandisa simba rekugadzira GND kupinza 1 ye modulator, uye iyo yakanaka terminal yemagetsi kupinza 2. Pin 3/4 ndiyo cathode uye anode yePD mukati memodulator. Kana iwe uchida kuishandisa, ndapota shandisa iyi PD nedunhu rekutora kumucheto kumashure, uye iyi PD inogona kushandiswa pasina kushandisa voltage (kana modulator isina PD yemukati, pini 3/4 iNC, pini yakamiswa).
d. Izvo zvinhu zveiyo intensity modulator ndeye lithium niobate. Kana munda wemagetsi unoshandiswa, iyo refractive index yekristaro ichachinja. Naizvozvo, kana voltage ikaiswa kune modulator, kurasikirwa kwekuiswa kweiyo modulator kuchasiyana neiyo yakashandiswa voltage. Vashandisi vanogona kudzora modulator pane imwe nzvimbo yekushandisa zvinoenderana nekushandiswa kwavo.
Zvekungwaririra
a. Iko kupinza kwemaziso kwemodulator hakufanire kudarika kukosha kwekuenzanisa papepa rebvunzo; kana zvisina kudaro, modulator ichakuvadzwa.
b. Iyo RF yekuisa yemodulator haifanire kudarika iyo yakatemerwa kukosha pane bvunzo sheet; kana zvisina kudaro, modulator ichakuvadzwa.
c. Iyo yakawedzerwa voltage yemodulator bias voltage pini ndeye ≤± 15V
2. Matanho ekushandisaphase modulator
a. Tarisa uone kana zviso zvekupedzisira zvekupinza / kubuda optical fibers ye intensity modulator yakachena. Kana paine mavara, ndapota pukuta iwo akachena nedoro.
b. Iyo phase modulator ndeye polarization-kuchengetedza yekuisa. Inokurudzirwa kushandisa polarization-inochengetedza mwenje sosi kana ichishandiswa (wavelength yemwenje sosi inotsamira pane inoshanda wavelength yemodulator), uye simba rechiedza rechiedza sosi rinonyanya 10dBm.
c. Paunenge uchishandisa chikamu modulator, batanidza iyo RF siginecha kune RF yekupinza chiteshi chemodulator.
d. Iyo phase modulator inogona kushanda mushure mekuwedzera redhiyo frequency chiratidzo, kupedzisa chikamuelectro-optic modulator. Chiedza chakagadziridzwa hachigone kuonekwa zvakananga nephotodetector seyo modulated radio frequency signal. Kazhinji, interferometer inoda kuiswa, uye redhiyo frequency signal inogona kuonekwa chete ne photodetector mushure mekupindira.
Zvekungwaririra
a. Iko kupinza kwemaziso kweEO modulator haifanire kudarika kukosha kwekuenzanisa papepa rebvunzo; kana zvisina kudaro, modulator ichakuvadzwa.
b. Iyo RF yekuisa yeEO modulator haifanire kudarika kukosha kwakatarwa papepa rebvunzo; kana zvisina kudaro, modulator ichakuvadzwa.
c. Paunenge uchigadzira interferometer, pane zvinodiwa zvakanyanya kune nzvimbo yekushandisa. Kuzunungusa kwezvakatipoteredza uye optical fiber swaying zvinogona kukanganisa mhinduro dzebvunzo.
