Ikizamini cya fibre optique yibizamini

Ikizamini cya fibre optique yibanze ikorwa na Optical Time Domain Reflectometer (OTDR).Nibikoresho bikoreshwa mugutahura neza amakosa mumashanyarazi ya fibre optique ihuza imiyoboro yitumanaho.OTDR itanga impiswi imbere ya fibre kugirango isuzumwe amakosa cyangwa inenge.Ibintu bitandukanye muri fibre birema Rayleigh inyuma itatanye.Indwara isubizwa muri OTDR hanyuma imbaraga zabo zipimwa hanyuma zikabarwa nkigikorwa cyigihe kandi zateguwe nkigikorwa cyo kurambura fibre.Imbaraga nibimenyetso byagarutse vuga ahantu hamwe nuburemere bwikosa rihari.Ntabwo ari ukubungabunga gusa, ahubwo na serivisi yo gushiraho umurongo wa optique ikoresha OTDRs.

OTDR ningirakamaro mugupima ubusugire bwa fibre optique.Irashobora kugenzura igihombo, gupima uburebure no kubona amakosa.OTDR nayo isanzwe ikoreshwa mugukora "ishusho" ya fibre optique mugihe imaze gushyirwaho.Nyuma, kugereranya birashobora gukorwa hagati yumwimerere numurongo wa kabiri wafashwe mugihe havutse ibibazo.Gusesengura inzira ya OTDR buri gihe byoroha nukugira ibyangombwa biva kumurongo wambere byakozwe mugihe umugozi washyizweho.OTDR ikwereke aho insinga zahagaritswe kandi wemeze ubuziranenge bwa fibre, amahuza na splices.Inzira za OTDR nazo zikoreshwa mugukemura ibibazo, kubera ko zishobora kwerekana aho ibiruhuko biri muri fibre mugihe ibimenyetso bigereranijwe nibyashizweho.

Jera komeza igeragezwa rya kabili ya FTTH kumurambararo (1310,1550 na 1625 nm).Dukoresha EXFO FTB-1 muriki kizamini cyiza.Gusuzuma ubuziranenge bwinsinga zacu kugirango tumenye neza ko abakiriya bacu bashobora kwakira ibicuruzwa byujuje ubuziranenge.

Dukora iki kizamini kuri buri nsinga dukora.
Laboratoire y'imbere irashoboye gukomeza urukurikirane rwibizamini bisanzwe bijyanye.
Murakaza neza kutwandikira kubindi bisobanuro.
