Kugira ngo abantu barusheho gukenera amakuru, umuvuduko wo kohereza sisitemu yo gutumanaho ya fibre optique uragenda wiyongera umunsi ku munsi. Umuyoboro w'itumanaho uzaza uzatera imbere werekeza kumurongo wa optique ya fibre itumanaho hamwe na ultra-yihuta, ubushobozi bwa ultra-nini, intera ndende-ndende, hamwe na ultra-high spekure ikora neza. Ikwirakwiza ni ngombwa. Ikwirakwizwa ryihuta ryihuta rya optique rigizwe ahanini na lazeri itanga ubwikorezi bwa optique, igikoresho cyerekana amashanyarazi yerekana amashanyarazi, hamwe na moderi yihuta ya electro-optique ihindura itwara optique. Ugereranije nubundi bwoko bwa modulator zo hanze, moderi ya lithium niobate electro-optique ifite ibyiza byo gukora inshuro nyinshi, guhagarara neza, igipimo kinini cyo kuzimangana, imikorere ihamye, imikorere ihindagurika, umuvuduko muke, guhuza byoroshye, guhuza ibicuruzwa bikuze, nibindi. ni Byinshi Byakoreshejwe Muri Byihuta, Ubushobozi-bunini, na sisitemu ndende ya optique yohereza.
Igice cya kabiri cyumubyigano nikintu gikomeye cyane cyumubiri wa moderi ya electro-optique. Yerekana impinduka muri bias voltage ihuye nibisohoka urumuri rwinshi rwa electro-optique modulator kuva byibuze kugeza kuri byinshi. Igena moderi ya electro-optique kurwego runini. Nigute ushobora gupima neza kandi byihuse umuvuduko wa kimwe cya kabiri cyumuvuduko wa moderi ya electro-optique ifite akamaro kanini mugutezimbere imikorere yigikoresho no kunoza imikorere yigikoresho. Igice cya kabiri cyumubyigano wa electro-optique modulator irimo DC (igice-cyuma
voltage na radiofrequency) igice cya kabiri cyumuvuduko. Ihererekanyabubasha rya moderi ya electro-optique niyi ikurikira:
Muri byo harimo ingufu za optique ya moderi ya electro-optique;
Ninjiza optique imbaraga za modulator;
Ese igihombo cyo kwinjiza moderi ya electro-optique;
Uburyo buriho bwo gupima igice cya kabiri cyumubyigano harimo kubyara agaciro gakabije nuburyo bwikubye kabiri, bushobora gupima icyerekezo cyumubyigano (DC) igice cya kabiri cyumubyigano hamwe na radio yumurongo wa radiyo (RF) igice cya kabiri cyumuvuduko wa modulator.

Ikora ku buryo bukurikira:
(1) Uburyo bw'agaciro gakabije
Uburyo bw'agaciro gakabije bukoreshwa mu gupima DC igice cya kabiri cya voltage ya moderi ya electro-optique. Ubwa mbere, nta kimenyetso cyerekana modulasiyo, ihererekanyabubasha ryimikorere ya electro-optique modulator iboneka mugupima ingufu za DC kubogama hamwe nisohoka ryumucyo mwinshi uhinduka, kandi uhereye kumurimo wo kwimura umurongo Kugena agaciro ntarengwa nigiciro ntarengwa, na shakisha DC ihuye nagaciro ka Vmax na Vmin. Hanyuma, itandukaniro riri hagati yibi byiciro byombi bya voltage nigice cya-voltage voltage Vπ = Vmax-Vmin ya moderi ya electro-optique.
(2) Uburyo bwo gukuba inshuro ebyiri
Yakoreshaga uburyo bwo gukuba inshuro ebyiri gupima RF igice cya kabiri cyumuvuduko wa moderi ya electro-optique. Ongeraho mudasobwa ya DC kubogama hamwe na AC modulation signal kuri moderi ya electro-optique icyarimwe kugirango uhindure ingufu za DC mugihe ingufu ziva mumucyo zahinduwe kugeza kumurongo ntarengwa cyangwa muto. Igihe kimwe, kandi birashobora kugaragara kuri oscilloscope ya kabiri-yerekana ko ibisohoka byahinduwe bizagaragara inshuro ebyiri kugoreka. Itandukaniro ryonyine rya voltage ya DC ihuye ninshuro ebyiri zegeranye zikubye kabiri kugoreka ni RF igice cya kabiri cyumubyigano wa moderi ya electro-optique.
Incamake: Byombi uburyo bwagaciro bukabije nuburyo bwikubye kabiri burashobora gupima mubyukuri igice cya kabiri cyumuvuduko wa moderi ya electro-optique, ariko kubigereranya, uburyo bukomeye bwagaciro busaba igihe kirekire cyo gupimwa, kandi igihe kinini cyo gupima kizaterwa Ibisohoka optique imbaraga za laser ihindagurika kandi itera amakosa yo gupima. Uburyo bw'agaciro gakabije bukeneye gusikana DC kubogama hamwe nintambwe ntoya kandi ukandika ibisohoka imbaraga za optique ya modulator icyarimwe kugirango ubone DC yuzuye igice cya kabiri cyumubyigano.
Uburyo bwo gukuba inshuro ebyiri nuburyo bwo kumenya igice cya kabiri cyumuvuduko ukurikiranira hafi inshuro ebyiri. Iyo ikoreshwa rya bias voltage igeze ku gaciro runaka, kugoreka inshuro kugoreka bibaho, kandi kugoreka imiyoboro ntigaragara cyane. Ntibyoroshye kwitegereza n'amaso. Muri ubu buryo, byanze bikunze bizatera amakosa akomeye, kandi icyo apima ni RF igice cya kabiri cyumuvuduko wa moderi ya electro-optique.
