Ponena za to Kulankhulana kwa kuwala, kuwongolera mphamvu kumatsimikizira kuti ndi njira yofunika kwambiri pankhani yokhazikika komanso luso la zizindikiro m'dera lomwe akufuna. Chifukwa cha kuwonjezeka kwa kufunikira kwa liwiro ndi mphamvu ya maukonde olumikizirana, pali kufunika kwenikweni koyendetsa mphamvu ya zizindikiro zowunikira zomwe zimatumizidwa kudzera mu fiber optics bwino. Izi zapangitsa kuti pakhale zotetezera za fiber optic ngati chofunikira pakugwiritsa ntchito ulusi. Amagwiritsidwa ntchito kwambiri pochepetsa mphamvu ya ma signal optical kuti akwere kwambiri zomwe zimapangitsa kuti zida zolandirira ziwonongeke kapena ngakhale mawonekedwe opotoka a ma signal.
Kuchepetsa kwa ulusi komwe ndi mfundo yoyambira mu ulalo wa fiber optic kungatanthauzidwe ngati kutayika komwe kumachitika pa mphamvu ya chizindikiro yomwe ili mu mawonekedwe a kuwala pamene ikudutsa mu chingwe cha fiber opticKuchepa kumeneku kungachitike chifukwa cha zifukwa zosiyanasiyana monga kutayika kwa magetsi, kuyamwa, ndi kupindika. Ngakhale kuchepa kwa chizindikiro ndi kwachibadwa, sikuyenera kufika pamlingo wokwera kwambiri chifukwa kumawononga magwiridwe antchito a makina olumikizirana ndi kuwala. Pofuna kuthetsa vutoli, ma attenuator amagwiritsidwa ntchito pochita izi kuti achepetse mphamvu ya chizindikiro kufika pamlingo wogwiritsidwa ntchito bwino komanso kuchepetsa mphamvu ya netiweki.
Mu njira yolumikizirana ya kuwala, chizindikirocho chiyenera kukhala ndi mphamvu inayake yomwe wolandirayo amafunikira kuti agwiritse ntchito chizindikirocho. Ngati chizindikirocho chili ndi mphamvu zambiri, chimadzaza wolandirayo ndipo nthawi zina chimayambitsa zolakwika, ndipo ngati chizindikirocho chili ndi mphamvu zochepa, ndiye kuti wolandirayo sangathe kuzindikira chizindikirocho molondola.Zochepetsera kuwala kwa fiber opticAmagwira ntchito yofunika kwambiri pakusunga bwino zinthu makamaka pamene mtunda uli waufupi zomwe zimapangitsa kuti pakhale mphamvu zambiri zomwe zingachititse phokoso.
Pali magulu awiri a ma fiber optic attenuators, omwe aliyense amasiyanitsidwa ndi kapangidwe kake ndi ntchito yake: Ma fixed attenuators ndi ma variable attenuators. Ma fiber optic attenuators amapezeka m'mapangidwe ndi mitundu yosiyanasiyana, ndipo iliyonse mwa iwo ndi yoyenera kugwiritsidwa ntchito kapena kufunikira kwina. Ma Fixed Attenuators ndi ma universal attenuators pomwe ma variable attenuators ndi ma attenuators enieni.
Zochepetsera Mphamvu Zokhazikika: Izi ndi zochepetsera mphamvu zomwe zimapereka kuchuluka koyenera kwa mphamvu ndipo zimagwiritsidwa ntchito nthawi zambiri, pomwe pakufunika kuchepetsa mphamvu kokhazikika. Zochepetsera mphamvu zokhazikika nthawi zambiri zimapangidwa kuti zigwirizane ndi kuchuluka kwa mphamvu zochepetsera mphamvu, zosiyanasiyana zomwe zimatha kusiyana kuyambira pa dB zingapo mpaka makumi a dB. Ubwino waukulu wa mitundu iyi ya ulusi ndi kusavuta kugwiritsa ntchito komanso kuyika mumakina osiyanasiyana olumikizirana ndi kuwala.
Zochepetsera Mphamvu Zosiyanasiyana: Kumbali inayi, zochepetsera mphamvu zosinthasintha zimalola ufulu wosintha kuchuluka kwa kuchepetsa mphamvu komwe kumagwiritsidwa ntchito chifukwa cha kusiyana kwake pakupanga kwa zochepetsera mphamvu. Kusintha kumeneku kungakhale kochitidwa ndi manja kapena kungathandizidwe pogwiritsa ntchito zowongolera zamagetsi. Zochepetsera mphamvu zosinthasintha zingagwiritsidwe ntchito m'malo osinthira mphamvu ya chizindikiro pomwe zizindikiro zingabwere ndi mphamvu zosiyanasiyana nthawi zosiyanasiyana ndipo motero mphamvu zawo zingafunike kusinthidwa nthawi ndi nthawi. Zimapezeka m'mayeso ambiri ndi muyeso pomwe zizindikiro zimasiyana komanso zimasiyana.
Chochepetsera kuwala kwa CHIKWANGWANIKomabe, munkhaniyi, amatanthauza chowonjezera chomwe chapangidwa ndi cholinga chofanana chochepetsera kuwala kufika pamlingo wokonzedweratu. Mwanjira ina, izi zitha kuchitika kudzera munjira monga kulowetsedwa, kufalikira, ndi kuwunikira. Zonse zitatuzi zili ndi zabwino zawo ndipo zimasankhidwa kutengera zomwe zafotokozedwa mu pulogalamu yomwe ikugwiritsidwa ntchito.
Zoletsa Kumwa: Zoletsa izi zimaphatikizapo zinthu zomwe zimamira bwino gawo la chizindikiro cha kuwala ndikuchiletsa kukhala champhamvu kwambiri. Chimodzi mwazinthu zazikulu zomwe ziyenera kuganiziridwa popanga zoletsa kutengera njira yogwiritsira ntchito yoletsa ndi kusankha zinthu ndi kapangidwe kake kuti izi zipereke kuchepa kwa nthawi zonse pamlingo womwe mukufuna popanda kubweretsa kutayika kwina.
Zochepetsera kuwala: Zochepetsera kuwala zomwe zimagwiritsa ntchito kuwala zimagwira ntchito motsatira mfundo yopangitsa dala kutayika mwa njira yosokoneza malo mu ulusi kotero kuti kuwala kwina komwe kumachitika kukugunda khoma lapakati ndikufalikira kunja kwa ulusi. Zotsatira zake, kufalikira kumeneku kumabweretsa kufooka kwa chizindikiro popanda kusokoneza mphamvu ya ulusi. Kapangidwe kake kayenera kutsimikizira kufalikira ndi mawonekedwe a PUF omwe amayembekezeredwa kuti akwaniritse milingo yofunikira yochepetsera kuwala.
Zowunikira Zowunikira: Zowunikira zowunikira zimagwira ntchito motsatira mfundo ya feedback, pomwe gawo la chizindikiro cha kuwala limabwereranso ku gwero, motero kuchepetsa kutumiza kwa chizindikiro kutsogolo. Zowunikira izi zitha kuphatikiza zinthu zowunikira monga magalasi mkati mwa njira yowunikira kapena malo a magalasi m'njira. Kapangidwe ka dongosolo kayenera kuchitika m'njira yoti zowunikira zisokoneze dongosolo mwanjira yoti mtundu wa chizindikiro umakhudzidwa.
Chochepetsera kuwala kwa CHIKWANGWANIs ndi zinthu zofunika kwambiri kuchokera ku makina amakono olumikizirana ndi kuwala, omwe opanga ayenera kusankha mosamala. Kudzera mu kayendetsedwe ka zizindikiro za mphamvu, zida izi zimatsimikizira kuyenda bwino kwa deta mkati mwa netiweki. Pakufalikira, kuchepetsedwa kwa ulusi ndi kufooka kwa chizindikiro chomwe chimachitika patali chifukwa cha kuwunikira kwa chizindikiro, kusokoneza, ndi kufalikira. Kuti athetse vutoli, pali mitundu yosiyanasiyana ya zochepetsera zomwe mainjiniya angafunike kudziwa ndikugwiritsa ntchito. Pakupititsa patsogolo ukadaulo wolumikizirana ndi kuwala, munthu sanganyalanyaze kugwira ntchito kwa zochepetsera za kuwala chifukwa zida zogwirira ntchito ndi kupanga zidzakhalabe zofunikira pa kulumikizana kwa nsanja zamakonozi.
