Ubwihindurize bwa Optical Node: Impinduramatwara mu miyoboro y'itumanaho

Mu rwego rwitumanaho ryitumanaho, iterambere rya optique ni impinduramatwara. Ipfundo rifite uruhare runini mugukwirakwiza amakuru, amajwi n'amashusho, kandi iterambere ryabo ryagize ingaruka cyane kumikorere n'umuvuduko wa sisitemu y'itumanaho rigezweho. Muri iyi blog, tuzareba ubwihindurize bwa optique nu ruhare rwabo muri rezo ya rezo y'itumanaho.

Igitekerezo cyaUmuyoboro mwizaamatariki kuva muminsi yambere ya fibre optique. Mu ikubitiro, iyi node yari ibikoresho byoroshye byakoreshwaga mu guhindura ibimenyetso bya optique mubimenyetso byamashanyarazi naho ubundi. Bakora nk'isano ihuza imiyoboro ya fibre optique n'ibikorwa remezo by'itumanaho bishingiye ku muringa. Nyamara, uko ikoranabuhanga rigenda ritera imbere, uruhare rwa optique rukomeza kwaguka, kandi rwabaye ikintu cy'ingenzi mu kohereza imiyoboro y'itumanaho igezweho.

Kimwe mu bintu by'ingenzi byateye imbere mu buhanga bwa optique ni uguhuza ibikorwa byo kugabana imirongo myinshi (WDM). WDM yemerera amakuru menshi yoherezwa icyarimwe hejuru ya fibre imwe ukoresheje uburebure butandukanye bwurumuri. Ikoranabuhanga ryongera cyane ubushobozi nubushobozi bwimiyoboro ya optique, bigafasha kohereza amakuru menshi kumuvuduko mwinshi.

Irindi terambere ryingenzi muri tekinoroji ya optique ni uguhuza optique ya optique. Izi amplifiseri zikoreshwa mukwongerera imbaraga ibimenyetso bya optique, bikabemerera koherezwa kure cyane bitabaye ngombwa ko ibikoresho bishya bihenze kandi bigoye. Kwinjiza optique ya optique muri optique yahinduye umukino kumiyoboro y'itumanaho rirerire, ituma hashyirwaho ubushobozi-buke, bwihuta cyane mumwanya muremure.

Mubyongeyeho, iterambere ryama optique ryatumye habaho iterambere rya optique yongeyeho opt-add multiplexers (ROADMs). Ibi bikoresho byemerera abakoresha imiyoboro ya kure gushakisha kure inzira ya optique murusobe rwabo, bigafasha kugabanura imbaraga z'umuyoboro mugari no kongera imiyoboro ihindagurika. Inzira ya ROADM ifasha optique ifite uruhare runini mugushiraho imiyoboro y'itumanaho yihuta, ihuza n'imihindagurikire y'ikirere ishoboye gukemura ibibazo byiyongera ku muyoboro mugari no guhuza.

Iterambere rya vuba muri tekinoroji ya optique ikubiyemo guhuza ubushobozi bwubwenge busobanurwa na neti (SDN). Ibi bituma kugenzura no gucunga imiyoboro ya optique, igafasha iboneza ryimikorere yumurongo hamwe nubuhanga bwogukora neza. SDN ifasha optique node itanga inzira yiterambere ryogutezimbere no kwikiza imiyoboro yitumanaho, ishoboye guhuza nimihindagurikire yimiterere mugihe nyacyo.

Muri make, iterambere ryaUmuyoboro mwizayagize uruhare runini mu mpinduramatwara y'itumanaho. Kuva mubikoresho byoroheje byo guhindura ibimenyetso kugeza kumurongo wibikoresho byubwenge bigoye, imiyoboro ya optique igira uruhare runini mugushoboza kohereza imiyoboro ihanitse cyane, yihuta. Mugihe ikoranabuhanga rikomeje gutera imbere, dushobora gutegereza udushya twinshi muburyo bwa tekinoroji ya optique, bigatuma habaho ihindagurika ryitumanaho ryitumanaho no guhindura ejo hazaza.
