Abahanga mu bya siyansi n'abahanga mu by'ikoranabuhanga bateje imbere ikoranabuhanga rigezweho risezeranya guhindura uburyo bwo gutumanaho mu kirere. Bakoresheje modulators zigezweho za 850nm zishyigikira 10G, gutakaza ingufu nke, ingufu nke z'amashanyarazi, hamwe n'ubudahangarwa bwinshi, itsinda ryashoboye gukora sisitemu yo gutumanaho mu kirere hamwe na sisitemu ihenze ya radiyo ishobora kohereza amakuru ku muvuduko mwinshi cyane nta bunini bukabije. Hamwe n'iri koranabuhanga rigezweho, ibikoresho byo mu kirere na satelite bishobora kohereza amakuru menshi ku muvuduko wihuse, bigatuma habaho itumanaho ryihuse n'Isi no gusangira amakuru neza hagati y'ibyogajuru. Iri ni iterambere ry'ingenzi mu bushakashatsi bw'ikirere, kuko itumanaho n'ibyogajuru byabaye imbogamizi ikomeye mu bushakashatsi bwa siyansi. Sisitemu yubatswe ku gihe gihamye cya cesium atomic, igenzura igihe cyo kohereza amakuru neza. Byongeye kandi, harimo icyuma gitanga impumuro kugira ngo kimenye neza uburyo ikimenyetso cy'urumuri gihinduka. Itsinda ryanashyizemo amahame ya quantum optics kugira ngo ryongere ubushobozi bwa sisitemu. Binyuze mu gukoresha imiterere ya quantum y'urumuri, bashoboye gukora sisitemu yo gutumanaho yizewe cyane idashobora kumviriza no gushakisha amakuru. Ikoreshwa ry'iri koranabuhanga ni rinini kandi rikwirakwiriye. Kuva ku itumanaho rya satelite ryihuse kandi ryizewe kugeza ku gusobanukirwa no gusobanukirwa neza isanzure ryacu, iri koranabuhanga rifite ubushobozi bwo guhindura ubushakashatsi bw’ikirere nkuko tubizi. Itsinda ririmo gukora kugira ngo rirusheho kunoza ikoranabuhanga no gusuzuma porogaramu zishobora gukoreshwa mu bucuruzi. Bitewe n’ubushobozi bwaryo bwo kohereza amakuru ku buryo bwihuse hamwe n’imikorere y’umutekano wongerewe, iyi sisitemu nshya y’itumanaho ry’ikirere izakenerwa cyane mu myaka iri imbere.
Modulator y'imbaraga za electro optique ya 850 nm 10G
Ibisobanuro bigufi:
ROF-AM 850nm lithium niobate optical intensity modulator ikoresha uburyo bwo guhanahana proton bugezweho, bufite igihombo gito cyo kwinjiramo, bandwidth yo hejuru yo guhinduranya, voltage ntoya ya half-wave, n'ibindi biranga, ahanini bikoreshwa muri sisitemu y'itumanaho ry'ikirere, cesium atomic time base, ibikoresho bitanga pulse, quantum optics, n'ibindi bice.
Ikoresha uburyo bwo guhanahana protoni bugezweho, bufite igihombo gito cyo gushyiramo, bandwidth yo hejuru yo guhinduranya, voltage ntoya ya half-wave, n'ibindi biranga, ahanini ikoreshwa muri sisitemu y'itumanaho ry'ikirere, igihe cya cesium atomic base, ibikoresho bitanga pulse, quantum optics, n'ibindi bice.
