Kugira ngo hamenyekane imiterere y’ikoreshwa ry’ibimenyetso by’urumuri bikoresha intera ndende n’ibitakaza bike, umurongo w’insinga ya fibre optique ugomba kuba wujuje imiterere y’ibidukikije. Ubusembwa ubwo aribwo bwose bugoramye cyangwa ubwandu bw’insinga za optique bushobora gutuma ibimenyetso by’urumuri bigabanuka ndetse bikanahagarika itumanaho.
1. Uburebure bw'umurongo w'inzira wa Fiber optique
Bitewe n'imiterere y'insinga z'amashanyarazi n'uburyo zitangana mu mikorere yazo, ibimenyetso by'amashanyarazi bikwirakwizwamo bihora bikwirakwira kandi bigashyirwamo. Iyo insinga ya fiber optique ibaye ndende cyane, bizatuma kugabanuka k'ibimenyetso by'amashanyarazi by'insinga zose birenga ibisabwa mu igenamigambi ry'umuyoboro w'itumanaho. Iyo kugabanuka k'ibimenyetso by'amashanyarazi ari binini cyane, bizagabanya ingaruka z'itumanaho.
2. Inguni yo kugonda y'aho insinga y'amashanyarazi iherereye ni nini cyane
Kugabanuka no kugabanuka kw'insinga za optique biterwa ahanini no guhinduka kw'insinga za optique, bigatuma zidakora neza mu gihe cyo kohereza optique. Insinga za optique zifite ubushobozi bwo kugonda, ariko iyo insinga ya optique igondamye ku nguni runaka, izatuma habaho impinduka mu cyerekezo cyo gukwirakwiza ikimenyetso cya optique mu nsinga, bigatuma igonda rigabanuka. Ibi bisaba kwitabwaho cyane kugira ngo habeho inguni zihagije zo gufunga insinga mu gihe cyo kubaka.
3. Insinga ya fibre optique irakandamizwa cyangwa yacitse
Iyi ni yo nzitizi ikunze kugaragara mu gihe insinga z'amashanyarazi zinanirwa gukora. Bitewe n'imbaraga zo hanze cyangwa ibiza, insinga z'amashanyarazi zishobora kugira imigozi mito idasanzwe cyangwa ndetse no kwangirika. Iyo icitsemo ibice cyangwa insinga z'amashanyarazi bigaragaye inyuma. Ariko, aho insinga zicitse, hazabaho impinduka mu gipimo cyo kugarura urumuri, ndetse no kubura urumuri, ibyo bikazangiza ubwiza bw'ikimenyetso cyoherezwa cya fibre. Muri iki gihe, koresha OTDR optical cable tester kugira ngo umenye aho insinga z'amashanyarazi zihagarara no kumenya aho insinga z'amashanyarazi zihagarara cyangwa aho zicika.
4. Kunanirwa kwinjiza uruhurirane rw'imiyoboro ya fibre optic
Mu gihe cyo gushyira insinga z'amashanyarazi, uduce duhuza insinga z'amashanyarazi dukunze gukoreshwa mu guhuza ibice bibiri by'insinga z'amashanyarazi muri kimwe. Bitewe no guhuza insinga z'ikirahure mu gice cy'ibanze cy'insinga z'amashanyarazi, ni ngombwa gukoresha neza agace gahuza insinga z'amashanyarazi hakurikijwe ubwoko bw'insinga z'amashanyarazi mu gihe cyo guhuza insinga z'amashanyarazi. Bitewe n'uko imirimo idakurikije amabwiriza y'ubwubatsi n'impinduka mu bwubatsi, biroroshye ko insinga z'amashanyarazi zanduzwa n'umwanda, bigatuma imyanda yivanga mu gihe cyo guhuza insinga z'amashanyarazi kandi bigatuma ubwiza bw'itumanaho ry'aho hantu hose bugabanuka.
5. Umurambararo w'insinga y'ibanze ya fibre uratandukanye
Insinga ya optique ya fibreGushyiramo ibintu akenshi bikoresha uburyo butandukanye bwo guhuza ibintu, nko guhuza ibyuma bifunganye, bikunze gukoreshwa mu gushyiramo imiyoboro ya mudasobwa mu nyubako. Imiyoboro ikora muri rusange ifite igihombo gito, ariko niba igice cy'inyuma cya fibre optique cyangwa flange kidasukuye mu gihe cyo guhuza ibintu, uburebure bwa fibre optique yo hagati buba butandukanye, kandi igice kidafunganye, byongera cyane igihombo cy'ingingo. Binyuze muri OTDR cyangwa igerageza ry'imbaraga ebyiri, amakosa yo kudahuza kwa diyametero yo hagati ashobora kugaragara. Ni ngombwa kumenya ko fibre imwe na fibre nyinshi zifite uburyo butandukanye bwo gutumanaho, uburebure bw'umurambararo, n'uburyo bwo kugabanya ibintu uretse uburebure bwa fibre yo hagati, bityo ntibishobora kuvangwa.
6. Kwanduzanya kwa fibre optique connector
Kwanduza imiyoboro y'inyuma y'urukuta n'ubushuhe bwo gusimbuka urukuta ni byo bintu by'ingenzi bituma insinga z'amashanyarazi zinanirwa. Cyane cyane mu miyoboro yo mu nzu, hari insinga nyinshi ngufi n'ibikoresho bitandukanye byo guhinduranya urukuta, kandi gushyiramo no gukuraho insinga z'inyuma, gusimbuza flange, no guhinduranya ni ibintu bikunze kubaho. Mu gihe cyo gukora, ivumbi rikabije, gutakaza ivumbi ryinshi, gutakaza no gukuramo urutoki, no gukoraho ku rutoki bishobora gutuma insinga z'inyuma z'urukuta zandura byoroshye, bigatuma umuntu atabasha guhindura inzira y'urukuta cyangwa kugabanya urumuri cyane. Hagomba gukoreshwa utubuto tw'inzoga mu gusukura.
7. Kutaryoha neza ku ngingo
Gusukura neza ingingo nabyo ni kimwe mu bibazo by’ingenzi mu miyoboro ya fiber optique. Imiterere myiza ya fiber optique ntabwo ibaho mu bidukikije nyabyo, kandi hari aho ihindagurika cyangwa imitumba. Iyo urumuri ruri mu miyoboro ya optique ruhuye n’iyo miyoboro, ubuso butari bumwe butuma urumuri rukwirakwira cyane kandi rukagira ishusho y’urumuri, ibyo bikaba byongera cyane uburyo urumuri rugabanuka. Ku murongo w’igerageza rya OTDR, agace k’uburyo igice kidasukuye neza kiba kinini cyane kuruta ako mu gice gisanzwe.
Ibibazo bikunze kubazwa
Ese aho icyuma gifata urumuri (optical port) gikeneye gufungurwa?
Ibikoresho byo gucunga umuyoboro bitarashyirwaho, uretse aho umuyoboro w'ikoranabuhanga wa "optical multiplexing port" ugomba gufungurwa, izindi switch zose zifite aho zikoresha "plug and play" zidasaba ko zishyirwaho kugira ngo zikoreshwe.
Nakora iki niba aho urumuri ruhagarara hataraka?
1. Reba niba umuvuduko w'igikoresho n'umuvuduko wa module ya optique byakoreshejwe bihuye.
2. Reba niba modules za optique zikoreshwa ku mpera zombi zihujwe.
3. Reba niba fibre ikoreshwa ihuye na module ya optique. Module ya optique ya single mode ikoresha fibre ya single mode, module ya optique ya multi mode ikoresha fibre ya multi mode, module ya optique ya dual fiber, kandi fibre ebyiri ku mpera imwe zisimburana ibumoso n'iburyo.
4. Reba niba umurongo wa fiber optique umeze neza hanyuma ukoreshe fibre ngufi mu gupima.
5. Igice cy'imbere cya ceramic cya module optique, fibre tail, cyangwa module optique ni umwanda cyane.
6. Module y'urumuri cyangwa fibre yo mu mugongo byangiritse, cyangwa se ihuza ry'imiyoboro y'urumuri ntirimeze neza.
Ikosa rijyanye na fibre optique ni ryo rigaragara cyane kandi rikunze kugaragara mu gihe cyo gukemura ibibazo cyangwa kubungabunga. Kubwibyo, hakenewe igikoresho kugira ngo harebwe niba ibyuka by'urumuri rwa fibre optique ari ibisanzwe. Ibi bisaba gukoresha ibikoresho byo gusuzuma amakosa ya fibre optique, nka optique power metters na red light pens. Optique power metters zikoreshwa mu gupima igihombo cya fibre optique kandi zoroshye gukoresha, zoroshye, kandi zoroshye gukoresha, bigatuma ziba amahitamo meza yo gukemura ibibazo bya fibre optique. Ikaramu y'urumuri rutukura ikoreshwa mu gushaka disiki ya fibre optique fibre optique iriho. Ibi bikoresho bibiri by'ingenzi mu gukemura ibibazo bya fibre optique, ariko ubu optique power metters na red light pen byahurijwe hamwe mu gikoresho kimwe, ibyo bikaba byoroshye kurushaho.
