Haba guhuza abaturage cyangwa kuzenguruka imigabane, umuvuduko nukuri nibyo bintu bibiri byingenzi bisabwa kuri fibre optique itwara itumanaho rikomeye. Abakoresha bakeneye imiyoboro yihuse ya FTTH hamwe na 5G igendanwa kugirango bagere kuri telemedisine, ibinyabiziga byigenga, inama ya videwo nubundi buryo bukoreshwa cyane. Mugihe hagaragaye umubare munini wibigo byamakuru hamwe niterambere ryihuse ryubwenge bwubuhanga hamwe no kwiga imashini, hamwe numuvuduko wihuse wumuyoboro hamwe ninkunga ya 800G no hejuru, ibiranga fibre byose byabaye ingenzi.
Ukurikije ITU-T G.650.3 isanzwe, optique yigihe cyerekana indangarubuga (OTDR), igikoresho cyo gupima igihombo cya optique (OLTS), ikwirakwizwa rya chromatic (CD), hamwe nibizamini bya polarisiyoneri (PMD) birasabwa gukora fibre yuzuye kandi ikanakora neza murwego rwo hejuru. Kubwibyo, gucunga indangagaciro za CD ni urufunguzo rwo kwemeza ubunyangamugayo no gukora neza.
Nubwo CD ari ibintu bisanzwe biranga fibre optique yose, aribwo kwagura imiyoboro ya Broadband intera ndende, ukurikije ITU-T G.650.3, gukwirakwiza biba ikibazo kuri fibre optique ifite igipimo cyo kohereza amakuru arenga 10 Gbps. CD irashobora kugira ingaruka zikomeye kumiterere yikimenyetso, cyane cyane muri sisitemu yitumanaho ryihuta, kandi kugerageza nurufunguzo rwo gukemura iki kibazo.
CD ni iki?
Iyo impanuka yumucyo yuburebure butandukanye ikwirakwira muri fibre optique, ikwirakwizwa ryumucyo rishobora gutera impiswi guhuzagurika no kugoreka, amaherezo bigatuma igabanuka ryubwiza bwikimenyetso cyatanzwe. Hariho uburyo bubiri bwo gutatanya: gutatanya ibintu no gukwirakwiza umurongo.
Ikwirakwizwa ryibikoresho ni ikintu cyihariye muburyo bwose bwa fibre optique, ishobora gutera uburebure butandukanye bwogukwirakwiza kumuvuduko utandukanye, amaherezo bikavamo uburebure bwumurongo bugera kuri transceiver ya kure mubihe bitandukanye.
Ikwirakwizwa rya Waveguide riboneka muburyo bwa waveguide ya fibre optique, aho ibimenyetso bya optique bikwirakwira binyuze mumyanya no kwambika fibre, bifite ibimenyetso bitandukanye byo kwanga. Ibi bivamo impinduka mumurambararo wa diametre yuburyo bwumurima no guhinduka mumuvuduko wikimenyetso kuri buri burebure.
Kugumana urwego runaka rwa CD ningirakamaro kugirango wirinde ko habaho izindi ngaruka zidafite umurongo, kubwibyo CD zeru ntabwo ari byiza. Ariko CD igomba kugenzurwa kurwego rwemewe kugirango wirinde ingaruka mbi kubuziranenge bwibimenyetso no muri serivisi nziza.
Ni izihe ngaruka z'ubwoko bwa fibre ku gutatanya?
Nkuko byavuzwe haruguru, CD ni kamere karemano iranga fibre optique, ariko ubwoko bwa fibre bugira uruhare runini mugucunga CD. Abakoresha imiyoboro irashobora guhitamo fibre cyangwa "fibre" ikwirakwiza fibre hamwe na fibre yo gutandukanya umurongo kugirango bagabanye ingaruka za CD murwego runaka.
Fibre ikoreshwa cyane mumiyoboro yiki gihe ni fibre isanzwe ya ITU-T G.652 hamwe no gutatanya bisanzwe. ITU-T G-653 ikwirakwizwa rya zeru ya fibre ntabwo ishyigikira kwanduza DWDM, mugihe G.655 yoherejwe na fibre fibre fibre ifite CD yo hasi, ariko ikaba yaratejwe imbere intera ndende kandi nayo ihenze cyane.
Ubwanyuma, abakoresha bagomba kumva ubwoko bwa fibre optique murusobe rwabo. Niba ibyinshi muri fibre optique ari bisanzwe G.652, ariko bimwe nubundi bwoko bwa fibre, noneho niba CD mumirongo yose idashobora kuboneka, ireme rya serivisi rizagira ingaruka.
Mu gusoza
Ikwirakwizwa rya Chromatic rikomeje kuba ikibazo kigomba gukemurwa kugirango habeho kwizerwa no gukora neza muri sisitemu yitumanaho ryihuse. Ibiranga fibre hamwe nigeragezwa ni urufunguzo rwo gukemura ibibazo bitatanye, bitanga ubushishozi kubatekinisiye naba injeniyeri gushushanya, kohereza, no kubungabunga ibikorwa remezo bitwara ubutumwa bukomeye ku isi. Hamwe niterambere rihoraho no kwagura urusobe, Softel izakomeza guhanga udushya no gutangiza ibisubizo ku isoko, iyoboye inzira yo gushyigikira ikoreshwa ryikoranabuhanga rigezweho.
