Yuav siv li casEO modulator
Tom qab tau txais EO modulator thiab qhib lub pob, thov hnav cov hnab looj tes electrostatic / wristbands thaum kov lub plhaub hlau lub plhaub ib feem ntawm lub cuab yeej. Siv cov tweezers kom tshem tawm cov khoom siv kho qhov muag / tso zis ntawm cov khoom siv los ntawm cov grooves ntawm lub thawv, thiab tom qab ntawd tshem tawm lub cev tseem ceeb ntawm lub modulator los ntawm daim txhuam cev grooves. Tom qab ntawd tuav lub cev tseem ceeb ntawm EO modulator nyob rau hauv ib tes thiab luag lub qhov muag pom kev tawm tswv yim / tso zis chaw nres nkoj ntawm lub modulator nrog rau lwm yam.
Kev npaj thiab tshuaj xyuas ua ntej siv
ib. Saib xyuas tias tsis muaj kev puas tsuaj rau cov khoom nto, module nto thiab lub tes tsho fiber ntau optical.
b. Xyuas kom pom tias daim ntawv lo yog dawb los ntawm cov av thiab cov ntawv lo lo ntxhuav-screen luam tawm kom meej.
c. Cov hluav taws xob flange tsis muaj kev puas tsuaj thiab tag nrho cov electrode pins tsis zoo.
d. Siv lub ntsej muag kho qhov muag fiber ntau lub ntsej muag los xyuas seb cov khoom siv kho qhov muag ntawm ob qhov kawg puas huv.
1. Cov kauj ruam rau kev sivsiv zog modulator
ib. Xyuas seb lub ntsej muag kawg ntawm cov tswv yim / tso zis optical fibers ntawm kev siv modulator puas huv. Yog tias muaj stains, thov so kom huv si nrog cawv.
b. Qhov kev siv zog modulator yog polarization-tso tawm tswv yim. Nws raug nquahu kom siv lub polarization-tswj lub teeb ci thaum siv (qhov wavelength ntawm lub teeb ci nyob ntawm qhov siv tau wavelength ntawm lub modulator), thiab lub teeb lub zog ntawm lub teeb ci yog 10dBm.
Thaum siv lub zog modulator, txuas lub hwj chim mov GND rau tus pin 1 ntawm lub modulator, thiab lub zoo davhlau ya nyob twg ntawm lub hwj chim mov rau tus pin 2. Pin 3/4 yog lub cathode thiab anode ntawm PD nyob rau hauv lub modulator. Yog tias koj xav siv nws, thov siv PD no nrog cov khoom lag luam hauv qab kawg, thiab PD no tuaj yeem siv yam tsis siv hluav taws xob (yog tias lub modulator tsis muaj PD sab hauv, tus pin 3/4 yog NC, tus pin raug tshem tawm).
d. Cov khoom siv ntawm kev siv zog modulator yog lithium niobate. Thaum siv hluav taws xob, qhov ntsuas qhov ntsuas ntawm cov siv lead ua yuav hloov. Yog li ntawd, thaum ib tug voltage yog thov mus rau lub modulator, lub insertion poob ntawm lub modulator yuav sib txawv nrog rau cov ntaub ntawv voltage. Cov neeg siv tuaj yeem tswj cov modulator ntawm ib qho chaw ua haujlwm raws li lawv qhov kev siv.
Cov kev ceev faj
ib. Cov tswv yim kho qhov muag ntawm lub modulator yuav tsum tsis pub tshaj tus nqi calibration ntawm daim ntawv xeem; txwv tsis pub, lub modulator yuav puas.
b. RF input ntawm lub modulator yuav tsum tsis txhob tshaj tus nqi calibrated ntawm daim ntawv xeem; txwv tsis pub, lub modulator yuav puas.
c. Qhov ntxiv voltage ntawm modulator bias voltage pin yog ≤ ± 15V
2. Cov kauj ruam siv lubtheem modulator
ib. Xyuas seb lub ntsej muag kawg ntawm cov tswv yim / tso zis optical fibers ntawm kev siv modulator puas huv. Yog tias muaj stains, thov so kom huv si nrog cawv.
b. Theem modulator yog polarization-tso cov tswv yim. Nws raug nquahu kom siv lub polarization-tswj lub teeb ci thaum siv (qhov wavelength ntawm lub teeb ci nyob ntawm qhov siv tau wavelength ntawm lub modulator), thiab lub teeb lub zog ntawm lub teeb ci yog 10dBm.
c. Thaum siv ib theem modulator, txuas RF teeb liab mus rau RF input chaw nres nkoj ntawm lub modulator.
d. Cov theem modulator tuaj yeem ua haujlwm tom qab ntxiv cov xov tooj cua zaus, ua tiav cov theemelectro-optic modulator. Lub teeb modulated tsis tuaj yeem tshawb pom ncaj qha los ntawm photodetector raws li lub xov tooj cua hloov pauv zaus. Feem ntau, ib qho interferometer yuav tsum tau teeb tsa, thiab lub xov tooj cua zaus teeb liab tsuas yog kuaj tau los ntawm photodetector tom qab cuam tshuam.
Cov kev ceev faj
a. Cov tswv yim kho qhov muag ntawm EO modulator yuav tsum tsis pub tshaj tus nqi calibration ntawm daim ntawv xeem; txwv tsis pub, lub modulator yuav puas.
b. RF input ntawm EO modulator yuav tsum tsis txhob tshaj tus nqi calibrated ntawm daim ntawv xeem; txwv tsis pub, lub modulator yuav puas.
c. Thaum teeb tsa tus interferometer, muaj cov kev xav tau siab heev rau kev siv ib puag ncig. Ib puag ncig co thiab optical fiber swaying tuaj yeem cuam tshuam rau qhov kev xeem.
