Uburyo Fiber Optic Reflectors ikoreshwa mu kugenzura umurongo wa PON Network Link

Mu miyoboro ya PON (Passive Optical Network), cyane cyane mu miterere ya PON ODN (Optical Distribution Network), gukurikirana no gusuzuma vuba amakosa ya fibre bitera imbogamizi zikomeye. Nubwo optical time domain reflectometers (OTDRs) ari ibikoresho bikoreshwa cyane, rimwe na rimwe ntibigira ubushobozi bwo kumenya uburyo ibimenyetso bigabanuka mu miyoboro ya ODN cyangwa ku mpera za fibre ya ONU. Gushyiramo fibre reflector ihendutse ihitamo uburebure ku ruhande rwa ONU ni ikintu gisanzwe gituma habaho gupima neza uburyo amasano y’urumuri agabanuka kuva ku mpera kugeza ku mpera.

Akayunguruzo k'umunyu gakoresha agace k'umunyu gakoresha imirasire y'urumuri kugira ngo gasubize inyuma umuvuduko w'ikizamini cya OTDR gasubira inyuma gafite hafi 100% by'ikirangiro. Hagati aho, uburebure busanzwe bw'umuvuduko w'urusobe rw'amashanyarazi rudakora (PON) bunyura muri aka gafunguzo gafite igabanuka rito kuko kadahuye n'imiterere ya Bragg ya kayunguruzo k'umunyu. Inshingano y'ingenzi y'ubu buryo ni ukubara neza agaciro k'igihombo cyo kugaruka kwa buri gikorwa cyo kugarura urumuri cya ONU ishami rimaze kurangira binyuze mu kumenya niba ikimenyetso cya OTDR cyagaragaye kirimo n'ubukana bwacyo. Ibi bituma hamenyekana niba isano iri hagati ya OLT na ONU ikora neza. Kubera iyo mpamvu, igenzura aho amakosa ari mu buryo bwihuse kandi bunoze.

Mu gushyiraho utumashini tugarura ubushyuhe mu buryo bworoshye kugira ngo tumenye ibice bitandukanye bya ODN, kumenya vuba, kumenya aho ibintu biherereye, no gusesengura impamvu z’amakosa ya ODN bishobora kugerwaho, bigabanyiriza igihe cyo gukemura amakosa mu gihe byongerera ubushobozi bwo gusuzuma no kubungabunga umurongo. Mu buryo bw’ibanze bwo gutandukanya, utumashini tugarura ubushyuhe twashyizwe ku ruhande rwa ONU bigaragaza ibibazo iyo utumashini tugarura ubushyuhe tw’ishami tugaragaje igihombo gikomeye cyo kugaruka ugereranije n’uko ibintu bimeze neza. Iyo amashami yose ya fibre afite utumashini tugarura ubushyuhe icyarimwe agaragaza igihombo gikomeye cyo kugaruka, bigaragaza ikibazo kiri muri fibre y’ingenzi.

Mu buryo bwa kabiri bwo gutandukanya, itandukaniro mu gutakaza umusaruro rishobora no kugereranywa no kumenya neza niba amakosa yo kugabanya umusaruro aboneka mu gice cy’umuyoboro w’amashanyarazi cyangwa igice cy’umuyoboro w’amashanyarazi. Haba mu bihe by’ibanze cyangwa iby’ibanze byo gutandukana, bitewe n’igabanuka ritunguranye ry’impeshyi zo kugarura urumuri ku mpera y’icyitegererezo cya OTDR, agaciro k’igihombo cyo kugaruka k’ishami rirerire cyane mu muyoboro wa ODN gashobora kutagereranywa neza. Kubwibyo, impinduka mu rwego rwo kugarura urumuri rw’umuyoboro w’amashanyarazi zigomba gupimwa nk'ishingiro ryo gupima no gusuzuma amakosa.

Utwuma dutanga urumuri dushobora no gushyirwa ahantu hakenewe. Urugero, gushyiraho FBG mbere yo kwinjira muri Fiber-to-the-Home (FTTH) cyangwa Fiber-to-the-Building (FTTB), hanyuma bigapimwa hifashishijwe OTDR, bituma hagereranywa amakuru y’ikizamini ugereranije n’amakuru y’ibanze kugira ngo hamenyekane amakosa y’imbere mu nzu/inyuma cyangwa imbere mu nyubako/inyuma.

Utugarura-mashusho twa Fiber optique dushobora gushyirwa mu buryo bworoshye ku ruhande rw'umukoresha. Igihe cyazo kirekire, icyizere gihamye, imiterere y'ubushyuhe buke, n'imiterere yoroshye yo guhuza adaptateri ni bimwe mu bituma ari amahitamo meza ya optique yo kugenzura umurongo wa FTTx. Yiyuantong itanga utwinjiza-mashusho twa FBG mu bwoko butandukanye bwo gupfunyika, harimo amaboko ya pulasitiki, amaboko ya frame y'icyuma, n'imiterere ya pigtail ifite SC cyangwa LC connectors.
