Kubyerekeye to itumanaho ryiza, kugenzura imbaraga byerekana ko ari uburyo bwingenzi iyo bigeze kumutekano kimwe no kumenya ibimenyetso mubigenewe. Hamwe no kwiyongera kwumuvuduko nubushobozi bwurusobe rwitumanaho, harakenewe rwose gucunga imbaraga zibimenyetso byurumuri byanyuze muri fibre optique neza. Ibi byatumye habaho kurema fibre optique nkibikenewe kugirango ukoreshwe muri fibre. Bafite porogaramu ikomeye mugukora nka attenuator bityo bikabuza imbaraga ibimenyetso bya optique kujya hejuru bitera kwangirika kubikoresho byakira cyangwa no kwerekana ibimenyetso byerekana ibimenyetso.
Fibre attenuation nihame ryibanze mumurongo wa fibre optique irashobora gusobanurwa nkigihombo gituruka kumbaraga zerekana ibimenyetso biri mumucyo uko inyura muri umugozi wa fibre optique. Iyi attenuation irashobora kubaho kubera impamvu zitandukanye zirimo gutatanya, gukurura, no kunama igihombo. Nubwo kwiyemeza ibimenyetso nibisanzwe rwose ntibigomba kugera kurwego rukabije kuko byangiza imikorere ya sisitemu yitumanaho ryiza. Kugira ngo iki kibazo gikemuke, attenuator ikoreshwa mubikorwa kugirango igabanye ubukana bwibimenyetso kugeza kurwego rwo kuyikoresha neza ningaruka ntoya mubuzima bwurusobe.
Muri an sisitemu y'itumanaho ryiza, ikimenyetso kigomba kuba cyurwego runaka rwingufu zikenerwa nuwakiriye gutunganya ibimenyetso. Niba ikimenyetso kirimo imbaraga nyinshi, noneho kirenza urugero uwakiriye kandi rimwe na rimwe kiganisha ku makosa, kandi niba ikimenyetso gitwara imbaraga nke, noneho uwakiriye ntashobora kumenya ibimenyetso neza.Fibre optiqueGira uruhare runini mukuzigama kuringaniza cyane cyane iyo intera ari ngufi bigatuma ingufu nyinshi zishobora kuba urusaku kumpera yakira.
Hano hari ibyiciro bibiri bya fibre optique, buri kimwekimwe gitandukanijwe nubwubatsi n'imikorere yacyo: Ibihamye kandi bihindagurika. Fibre optic attenuator iboneka mubishushanyo n'ubwoko butandukanye, kandi buri kimwe muricyo gikwiye gukoreshwa cyangwa gukenera. Attenuator ihamye ni attenuator yisi yose mugihe impinduka zihinduka ni attenuator yihariye.
Attenuator zihamye: Izi ni attenuator zitanga urugero rusanzwe rwa attenuation kandi zikoreshwa cyane mubihe, aho bisabwa urwego ruhoraho rwo kwiyerekana. Ibikoresho bitunganijwe bisanzwe bikorerwa murwego rwihariye rwo kwiyegereza, bitandukanye birashobora gutandukana kuva dB nyinshi kugeza kuri mirongo ya dB. Inyungu nyamukuru yubwoko bwa fibre nuburyo bworoshye bwo gukoresha kimwe no kwishyiriraho muri sisitemu zitandukanye zisanzwe zitumanaho.
Impinduka zinyuranye: Kurundi ruhande, impinduka zihindagurika zemerera umudendezo wo gutandukanya ingano ya attenensiya ikoreshwa bitewe nuburyo butandukanye muburyo bwa attenuator. Ihinduka rishobora kuba intoki zuzuye cyangwa rishobora koroherezwa no gukoresha igenzura rya elegitoroniki. Impinduka zinyuranye zirashobora gukoreshwa muburyo bwo guhindura ibimenyetso byerekana ibimenyetso aho ibimenyetso bishobora kuza kumbaraga zitandukanye mubihe bitandukanye bityo rero aho imbaraga zabo zishobora gukenera guhinduka mugihe kimwe. Bashobora kuboneka mubizamini byinshi no gupima aho ibimenyetso bitandukanye kandi bitandukanye.
Fibre optiquemuriki gice, ariko, bisobanura ibikoresho byateguwe bifite intego imwe yo guhuza urumuri kurwego rwateganijwe. Muyandi magambo, ibi birashobora gukorwa binyuze mubikorwa nka adsorption, diffaction, no gutekereza. Bose uko ari batatu bafite ibyiza kandi baratoranijwe bitewe nibisobanuro bya porogaramu ishyirwa mubikorwa.
Absorptive Attenuator: Izi attenuator zirimo ibintu byinjiza neza igice cyibimenyetso bya optique kandi bikarinda gukomera. Kimwe mu bintu byingenzi byashushanyijemo mugihe utezimbere ibyiyumvo bishingiye kubikorwa byo gukurura ibintu ni uguhitamo ibikoresho n'imiterere kuburyo ibyo byatanga umurongo uhoraho hafi yumurongo wifuzwa utarinze gutakaza igihombo cyinyongera.
Ikwirakwizwa rya Attenuator: Gukwirakwiza urumuri rushingiye ku ihame ryo gukurura nkana igihombo muburyo bwo kugoreka umwanya muri fibre kuburyo bimwe mubyabaye urumuri rwibasiye urukuta rwibanze hanyuma bigatatanwa muri fibre. Nkigisubizo, iyi ngaruka yo gukwirakwiza itera intege nke yikimenyetso utabangamiye ubushobozi kavukire bwa fibre. Igishushanyo kigomba kwemeza gukwirakwiza no gutegurwa kwa PUF kugirango bagere kurwego rusabwa.
Ibitekerezo byerekana: Ibitekerezo byerekana bikora ku ihame ryo gutanga ibitekerezo, aho igipimo cy'ikimenyetso cy'urumuri gisubizwa inyuma kiva ku isoko, bityo bikagabanya kohereza ibimenyetso mu cyerekezo cyerekeza. Izi attenuator zirashobora gushiramo ibice byerekana nkindorerwamo munzira nziza cyangwa gushyira indorerwamo kumuhanda. Imiterere ya sisitemu igomba gukorwa muburyo bwo gutekereza kubangamira sisitemu kuburyo ubwiza bwibimenyetso bugira ingaruka.
Fibre optiques nibicuruzwa byingenzi bya sisitemu yo gutumanaho igezweho, abayishushanya bagomba guhitamo neza. Binyuze mu kugenzura ibimenyetso byimbaraga, ibyo bikoresho byemeza neza amakuru neza murusobe. Mu gutatanya, fibre attenuation ni intege nke yikimenyetso kibaho hejuru yintera bitewe no kwerekana ibimenyetso, kwivanga, no gutandukana. Kugira ngo ukemure iki kibazo, hari ubwoko butandukanye bwa attenuator abajenjeri bashobora kumenya no gukoresha. Mugutezimbere kwikoranabuhanga ryitumanaho rya optique, umuntu ntashobora kwirengagiza imikorere ya fibre optique kuko ibikoresho byo gukanda no gushushanya bizakomeza kuba ingirakamaro muguhuza ibyo bibuga bikomeye.
