Itumanaho rya fibre optique nuburyo nyamukuru bwo kohereza imiyoboro igezweho. Amateka yiterambere ryayo ni imyaka imwe cyangwa ibiri gusa. Yiboneye ibisekuruza bitatu: fibre ngufi ya fibre fibre, fibre ndende ya fibre ndende na fibre ndende-imwe ya fibre. Gukoresha itumanaho rya fibre optique nimpinduka nini mumateka yitumanaho. Kugeza ubu, itumanaho rya fibre optique yo mu Bushinwa ryageze mu ntera ifatika. Byongeye kandi, ibihugu byinshi byatangaje ko bitazongera kubaka umurongo w’itumanaho kandi byiyemeje guteza imbere itumanaho rya fibre optique.
Intangiriro kuri Optical Fibre Itumanaho
Itumanaho ryitwa optique fibre itumanaho ikoresha fibre optique yohereza imiyoboro yumucyo itwara amakuru kugirango igere ku ntego zitumanaho. Kugirango ukore urumuri rworoheje rutwara amakuru, rugomba guhindurwa, kandi amakuru akamenyekana kuva kumurabyo wumucyo kurangiriraho.Nk'ikoranabuhanga, itumanaho rya fibre optique rifite amateka yimyaka 30 kugeza 40, ariko rifite yahinduye rwose isura yitumanaho ryisi, kandi iterambere ryayo rizaza ntagereranywa.
Ihame rya fibre optique itumanaho no kohereza
Ihame ryitumanaho rya fibre optique: kumpera yohereza, amakuru yatanzwe (nkijwi) abanza guhindurwa ikimenyetso cyamashanyarazi, hanyuma agahindurwa kumurabyo wa lazeri yasohowe na lazeri, kuburyo ubukana bwurumuri buhinduka hamwe na amplitude (frequency) yikimenyetso cyamashanyarazi, no Kohereza binyuze muri fibre. Kurangiza kwakirwa, detector yakira ibimenyetso bya optique ikabihindura mubimenyetso byamashanyarazi, byerekanwa kugirango bigarure amakuru yumwimerere.
Ibyiza
(1) Ubushobozi bwitumanaho ni bunini kandi intera yohereza ni ndende.
(2) Gutakaza fibre ni bike cyane.
(3) Ibimenyetso bito bivanga hamwe nibanga ryiza.
(4) Kurwanya anti-electromagnetic kwivanga, ubwiza bwogukwirakwiza.
(5) Fibre ni ntoya mubunini n'umucyo muburemere, byoroshye kurambika no gutwara.
(6) Ikungahaye ku bikoresho no kurengera ibidukikije, bifasha kuzigama umuringa w'icyuma udafite fer.
(7) Nta mirasire, biragoye kubyumva.
(8) Umugozi ufite imiterere ihindagurika kandi iramba.
Ingaruka
(1) Imiterere iracitse kandi imbaraga za mashini ni mbi.
(2) Gukata no gutema fibre optique bisaba ibikoresho, ibikoresho nubuhanga.
(3) Gutandukana no guhuza ntabwo byoroshye.
(4) Iradiyo yunamye ya fibre optique ntigomba kuba nto cyane (> 20cm).
(5) Hariho ikibazo cyo gutanga amashanyarazi.
Iterambere ryiterambere ryitumanaho rya fibre optique
Muri iki gihe, igurishwa ry’ibikoresho by’itumanaho rya fibre optique hamwe n’umugozi wa optique mu Bushinwa biriyongera buri mwaka. Mu byaro byinshi byo mu ntara n’imijyi myinshi yo mu Bushinwa, kubaka itumanaho rya terefone biracyari ubusa. Mubyongeyeho, hamwe niterambere rya serivise mugari no gukenera kwaguka, itumanaho rya optique ya fibre optique Isoko ni rinini.
