Ponena to kulumikizana kwa kuwala, kuwongolera mphamvu kumatsimikizira kukhala njira yofunikira ikafika pakukhazikika komanso luso lazizindikiro zomwe akuzifuna. Ndi kuwonjezeka kwa kufunikira kwa liwiro ndi mphamvu ya maukonde olankhulana, pakufunika kwenikweni kuyang'anira mphamvu ya ma siginecha a kuwala omwe amafalitsidwa kudzera mu fiber optics bwino. Izi zapangitsa kulengedwa kwa fiber optic attenuators ngati kufunikira kogwiritsa ntchito ulusi. Amakhala ndi ntchito yovuta kwambiri pochita ngati zowongolera motero amalepheretsa mphamvu ya ma siginecha owoneka kuti apite pamwamba kuwononga zida zolandirira kapenanso mawonekedwe opotoka.
Fiber attenuation yomwe ndi mfundo yofunikira mu ulalo wa fiber optic imatha kufotokozedwa ngati kutayika komwe kumachitika pa mphamvu ya siginecha yomwe ili mu mawonekedwe a kuwala pamene ikudutsa CHIKWANGWANI chamawonedwe chingwe. Kuchepetsa uku kumatha kuchitika chifukwa chazifukwa zosiyanasiyana zomwe zimabalalika, kuyamwa, ndi kutayika. Ngakhale kuchepetsedwa kwa chizindikiro ndikwabwinobwino sikuyenera kufika pamlingo wopitilira muyeso chifukwa kumawononga magwiridwe antchito amagetsi olumikizirana. Kuti athetse vutoli, ma attenuators amagwiritsidwa ntchito kuti achepetse mphamvu yazizindikiro kuti ifike pakugwiritsa ntchito moyenera komanso kukhudza pang'ono pautali wa moyo wa intaneti.
Mu a optical communication system, chizindikirocho chiyenera kukhala cha mlingo wina wa mphamvu womwe umafunika ndi wolandira kuti agwiritse ntchito chizindikirocho. Ngati chizindikiro chili ndi mphamvu zambiri, ndiye kuti chimadzaza ndi wolandirayo ndipo nthawi zina chimayambitsa zolakwika, ndipo ngati chizindikirocho chili ndi mphamvu zochepa, ndiye kuti wolandirayo sangathe kuzindikira chizindikirocho molondola.Fiber optic attenuatorskhala ndi gawo lalikulu posunga kukhazikika koteroko makamaka ngati mtunda uli waufupi zomwe zimapangitsa kuti pakhale mphamvu zambiri zomwe zimatha kukhala phokoso polandira.
Pali magulu awiri a fiber optic attenuators, iliyonse yomwe imasiyanitsidwa ndi kapangidwe kake ndi ntchito yake: Zowongolera zokhazikika ndi zowongolera zosinthika. Fiber optic attenuators amapezeka m'mapangidwe ndi mitundu yosiyanasiyana, ndipo iliyonse ndi yoyenera kugwiritsidwa ntchito kapena chosowa china. Ma Attenuators Okhazikika ndi zowonera konsekonse pomwe zowongolera zosinthika zimakhala zowongolera zenizeni.
Okhazikika Okhazikika: Awa ndi ochepetsera omwe amapereka kuchuluka kwanthawi yayitali ndipo amagwiritsidwa ntchito nthawi zambiri, pomwe mulingo wokhazikika wochepetsera umafunika. Ma attenuators osasunthika nthawi zambiri amapangidwira milingo yochepetsetsa, yosiyanasiyana yomwe imatha kusiyanasiyana kuchokera ku ma dB angapo mpaka makumi a dB. Ubwino waukulu wa mitundu iyi ya ulusi ndikusavuta kugwiritsa ntchito komanso kuyika munjira zosiyanasiyana zolumikizirana ndi kuwala.
Zothandizira Zosintha: Kumbali ina, zowongolera zosinthika zimalola ufulu wosintha kuchuluka kwa kuchepetsedwa komwe kumagwiritsidwa ntchito chifukwa cha kusiyanasiyana kwake pamapangidwe ake. Kusintha kumeneku kumatha kukhala pamanja kwathunthu kapena kutha kuthandizidwa pogwiritsa ntchito zowongolera zamagetsi. Ma attenuators osinthika amatha kugwiritsidwa ntchito m'makhazikitsidwe amphamvu azizindikiro pomwe ma siginecha amatha kubwera mwamphamvu mosiyanasiyana nthawi zosiyanasiyana kotero kuti mphamvu zawo zingafunikire kusinthidwa nthawi ndi nthawi. Atha kupezeka m'mayesero ambiri ndi miyeso pomwe ma sign amasiyana komanso amasiyana.
Fiber optic attenuatorm'nkhaniyi, komabe, amatanthauza chowonjezera chomwe chapangidwa ndi cholinga chofanana chochepetsera kuwala kumlingo wokonzedweratu. Mwanjira ina, izi zitha kuchitika kudzera munjira monga adsorption, diffraction, and reflection. Onse atatu ali ndi zabwino zawo ndipo amasankhidwa malinga ndi momwe ntchito ikugwiritsidwira ntchito.
Ma Absorptive Attenuators: Ma attenuators awa amaphatikiza zinthu zomwe zimamiza bwino 'gawo la siginecha ya kuwala ndikuletsa kuti likhale lamphamvu kwambiri. Chimodzi mwazinthu zazikulu zamapangidwe popanga zowongolera potengera makina ogwiritsira ntchito mayamwidwe ndi kusankha kwa zinthu ndi kapangidwe kake kotero kuti izi zipereka chitonthozo chokhazikika pautali wofunidwa popanda kubweretsa zotayika zina.
Zothandizira Zobalalitsa: Zowunikira zotsatsira mopepuka zimagwira ntchito pa mfundo yopangitsa dala kutayika mwa mawonekedwe a kupotoza kwa malo mu ulusi kotero kuti kuwala kwina kugunda khoma lapakati ndikubalalika kunja kwa ulusi. Zotsatira zake, kufalikira kumeneku kumabweretsa kufowoka kwa chizindikirocho popanda kusokoneza kuthekera kwachilengedwe kwa ulusi. Kapangidwe kake kamayenera kutsimikizira kugawa ndi kuyembekezeredwa kwa ma PUF kuti athe kukwaniritsa zofunikira.
Zowunikira Zowunikira: Zowunikira zowunikira zimagwira ntchito poyankha, pomwe gawo la siginecha ya kuwala imabwezeredwa ku gwero, motero kumachepetsa kutumiza kwa siginecha kupita kutsogolo. Zothandizira izi zingaphatikizepo zinthu zowunikira monga magalasi mkati mwa njira ya kuwala kapena kuika magalasi m'mphepete mwa njira. Kukonzekera kwadongosolo kuyenera kuchitidwa m'njira yoti zowonetsera zisokoneze dongosolo kuti khalidwe la chizindikiro limakhudzidwe.
Fiber optic attenuators ndi zinthu zofunika kwambiri zamakina amakono olumikizirana, omwe opanga ayenera kusankha mosamala. Kupyolera mu kayendetsedwe ka zizindikiro za mphamvu, zidazi zimatsimikizira kutetezedwa kotetezedwa ndi koyenera kwa deta mkati mwa intaneti. Mu kubalalitsidwa, kuchepetsedwa kwa ulusi ndiko kufowoka kwa siginecha komwe kumachitika pamtunda woperekedwa chifukwa cha kuwunikira, kusokoneza, ndi kutayika. Kuti athane ndi vutoli, pali mitundu yosiyanasiyana ya zowunikira zomwe mainjiniya angafunikire kudziwa ndikugwiritsa ntchito. M'kupita patsogolo kwaukadaulo waukadaulo wolumikizirana, munthu sanganyalanyaze kugwira ntchito kwa ma fiber optic attenuators popeza zida zolumikizira ndi kupanga zizikhalabe zofunikira pakulumikizana kwamapulatifomu apamwambawa.
