Nigute ushobora gukoresha moderi ya EO

Uburyo bwo gukoreshaModeri ya EO

Nyuma yo kwakira moderi ya EO no gufungura paki, nyamuneka wambare uturindantoki twa electrostatike / amaboko mugihe ukoraho icyuma cyigice cyigikoresho. Koresha twezeri kugirango ukureho optique yinjiza / isohoka ibyambu byibikoresho biva mu gasanduku, hanyuma ukureho umubiri nyamukuru wa modulator muri sponge. Noneho fata umubiri wingenzi wa moderi ya EO mukiganza kimwe hanyuma ukurura optique yinjiza / isohoka icyambu cya modulator hamwe nundi.

Gutegura no kugenzura mbere yo gukoresha

a. Reba neza ko nta byangiritse kubicuruzwa, hejuru ya module hamwe na fibre optique.

b. Reba neza ko ikirango kitarangwamo umwanda kandi ibimenyetso bya silk-ecran byerekana neza.

c. Amashanyarazi yumuriro ntabwo yangiritse kandi pin zose za electrode ntizihinduka.

d. Koresha optique ya fibre optique ya face detector kugirango urebe niba fibre optique kumpera zombi zifite isuku.

1. Intambwe zo gukoreshamodulator

a. Reba niba impera yanyuma yinjiza / isohoka optique ya fibre yububasha bwa modulator isukuye. Niba hari ikizinga, nyamuneka ubahanagure hamwe n'inzoga.

b. Imbaraga modulator ni polarisiyasi-ikomeza kwinjiza. Birasabwa gukoresha polarisiyasi-ikomeza isoko yumucyo mugihe ikoreshwa (uburebure bwumurongo wumucyo biterwa nuburebure bwumurongo wa modulator), kandi imbaraga zumucyo zituruka kumucyo nibyiza 10dBm.

Mugihe ukoresheje imbaraga modulator, huza amashanyarazi GND kuri pin 1 ya modulator, hamwe na terefone nziza yo gutanga amashanyarazi kuri pin 2. Pin 3/4 ni cathode na anode ya PD imbere muri modulator. Niba ukeneye kuyikoresha, nyamuneka koresha iyi PD hamwe numuzunguruko wo kugura kumpera yinyuma, kandi iyi PD irashobora gukoreshwa udashyizeho voltage (niba modulator idafite PD y'imbere, pin 3/4 ni NC, pin ihagaritswe).

d. Ibikoresho byimbaraga modulator ni lithium niobate. Iyo umurima wamashanyarazi ushyizwe mubikorwa, indangantego yo kwanga ya kristu izahinduka. Kubwibyo, iyo voltage ikoreshwa kuri modulator, igihombo cyo kwinjiza modulator kizahinduka hamwe na voltage ikoreshwa. Abakoresha barashobora kugenzura modulator mugihe runaka gikora ukurikije imikoreshereze yabo.

Kwirinda

a. Ibyiza bya optique ya modulator ntibigomba kurenza agaciro ka kalibrasi kurupapuro rwibizamini; bitabaye ibyo, modulator yangiritse.

b. RF yinjiza modulator ntigomba kurenza agaciro kateganijwe kurupapuro rwibizamini; bitabaye ibyo, modulator yangiritse.

c. Wongeyeho imbaraga za modulator bias voltage pin ni ≤ ± 15V

2. Intambwe zo gukoreshaicyiciro

a. Reba niba impera yanyuma yinjiza / isohoka optique ya fibre yububasha bwa modulator isukuye. Niba hari ikizinga, nyamuneka ubahanagure hamwe n'inzoga.

b. Icyiciro modulator ni polarisiyasi-ikomeza kwinjiza. Birasabwa gukoresha polarisiyasi-ikomeza isoko yumucyo mugihe ikoreshwa (uburebure bwumurongo wumucyo biterwa nuburebure bwumurongo wa modulator), kandi imbaraga zumucyo zituruka kumucyo nibyiza 10dBm.

c. Mugihe ukoresheje icyiciro cya moderi, huza ibimenyetso bya RF nicyambu cya RF cyinjira muri modulator.

d. Moderi yicyiciro irashobora gukora nyuma yo kongeramo ibimenyetso bya radio yumurongo, ikarangiza icyiciroamashanyarazi ya optique. Itara ryahinduwe ntirishobora gutahurwa na fotodetekeri nkikimenyetso cya radiyo yahinduwe. Mubisanzwe, interterometero igomba gushyirwaho, kandi ibimenyetso bya radiyo yumurongo bishobora kugaragara gusa na fotodetekeri nyuma yo kwivanga.

a. Ibyiza bya optique ya moderi ya EO ntibigomba kurenza agaciro ka kalibrasi kurupapuro rwibizamini; bitabaye ibyo, modulator yangiritse.

b. RF yinjiza ya moderi ya EO ntigomba kurenza agaciro kateganijwe kurupapuro rwibizamini; bitabaye ibyo, modulator yangiritse.

c. Mugihe ushyizeho interterometero, haribisabwa cyane murwego rwo gukoresha ibidukikije. Kunyeganyeza ibidukikije hamwe na fibre optique ihindagurika byombi bishobora kugira ingaruka kubisubizo.
