Kusankha zinthu zoyenera kumayendetsedwa ndi zosowa zapadera za netiweki iliyonse, kuphatikizapo liwiro, mtunda, ndi momwe ntchito ikugwiritsidwira ntchito.

Njira Zoyenera Zogwirira Ntchito

Choncho n'zoonekeratu kuti kusamalira mosamala pakukhazikitsa ndi kukonza nthawi zonse n'kofunika kwambiri. Musapindire zingwe kuposa utali wocheperako ndipo gwiritsani ntchito zolumikizira ulusi wa Bragg kuti muyese kupsinjika.

Tsatirani malangizo awa:

Chitani izi: Gwiritsani ntchito magolovesi oteteza, sungani zingwe bwino, ndipo yang'anani momwe zinthu zilili.

Musakoke: Kokani zingwe mwamphamvu, limbitsani kwambiri ma clamp, kapena kuziyika pa kutentha.

Mapeto

Chingwe cha fiber optic chimagwira ntchito ngati maziko a kutumiza deta mwachangu komanso modalirika. Kaya ndi makulidwe, zipangizo, kapena ukadaulo, mbali iliyonse ya chingwecho imakhudza liwiro, kumveka bwino, komanso kugwira ntchito bwino. Kusankha mtundu woyenera wa chingwecho, kutsatira njira zoyenera zoyikira, komanso kutsatira ukadaulo watsopano kudzakuthandizani kupeza zotsatira zabwino kwambiri. Ndi kuwongolera khalidwe ndi zatsopano zomwe zikubwera nthawi zonse, kupititsa patsogolo ma fiber optics, chingwe cha fiber optic chakhala gawo lofunikira kwambiri pakulankhulana kwamakono.

Kaya mukukonzekera kulumikizana kwa mtunda womaliza kapena kufalikira mdziko lonse, kudziwa zomwe zili pansi pa kutsatsa kudzakuthandizani kupanga zisankho zanzeru. Fiber optics ndi sayansi yolondola komanso yogwira ntchito, ndipo pakatikati ndiye pakatikati pa sayansi. Kuti muwonetsetse kuti kulumikizana mwachangu komanso kodalirika komanso kuti deta ikuyenda bwino, ndikofunikira kuyika ndalama mu pakatikati koyenera.

Mafunso Ofunsidwa Kawirikawiri

Kodi maziko a chingwe cha fiber optic ndi chiyani?

Chimake ndi galasi lopyapyala, lapakati kapena chingwe cha pulasitiki cha chingwe cha fiber optic. Ndi gawo la chingwe cha fiber optic chomwe chimanyamula zizindikiro zowunikira kuti zitumize deta. Ubwino ndi kukula kwa chimake ndizofunikira kwambiri kuti deta yambiri isamutsidwe bwino.

Kodi maziko amakhudza bwanji kutumiza deta?

Pakati pa chinthucho pamagwira ntchito ngati njira yomwe zizindikiro za kuwala zimadutsa kuti zitumizire deta. Pakati pa chinthucho pamakhala pomveka bwino komanso mokhazikika, deta imatha kutumizidwa mwachangu komanso modalirika kudzera mu ulusi popanda kutayika kapena kusokonezedwa ndi deta.

Kodi kusiyana pakati pa ma cores a single-mode ndi multi-mode ndi kotani?

Ma cores a single-mode amapanga kuwala kotulutsa kamodzi, ndi ochepa (pafupifupi ma microns 8-10) ndipo ndi oyenera kwambiri mtunda wautali. Ma cores a multi-mode amapereka ma cores akuluakulu (ma microns 50-62.5) ndipo amagwiritsidwa ntchito mtunda waufupi wokhala ndi ma bandwidth apamwamba.

Kodi ndi zinthu ziti zomwe zimakhudza magwiridwe antchito a fiber optic core?

Kugwira ntchito bwino kwa core kumakhudzidwa ndi ubwino wa zinthu, ukhondo, kulondola kwa pakatikati, ndi kuyika mu chubu cha chingwe. Ngakhale zinthu zakunja, monga pamene chingwe chimapindika kapena kutambasulidwa pamene chikugwiritsidwa ntchito, zingakhudze momwe chimagwirira ntchito.

Kodi khalidwe lapakati limayendetsedwa bwanji panthawi yopanga?

Opanga amadalira nsanja zamakono zojambula ulusi kuti atsimikizire kulondola kwa pakatikati pa chivindikiro, kuyera kwa zinthu, komanso kulimba kwa chilema cha kristalo. Kuyesa kolimba kumatsimikizira kugwira ntchito kosalekeza komanso kutsatira miyezo ya ANSI/TIA.

Kodi kuyika kosayenera kungawononge fiber optic core?

Inde. Kupindika kwambiri kapena kupanikizika komwe kumagwiritsidwa ntchito pa chingwe cha fiber optic panthawi yoyika kumatha kuswa kapena kusokoneza pakati, zomwe zimapangitsa kuti chizindikiro chitayike kapena kusokonezedwa. Kutsatira njira zabwino ndikofunikira.

Kodi ndi zinthu zatsopano ziti zomwe zachitika posachedwapa mu ukadaulo wa fiber optic core?

Zina mwa zinthu zomwe zachitika posachedwapa ndi ma cores osakhudzidwa ndi kupindika, mphamvu zapamwamba za bandwidth, ndi zipangizo zosungira chilengedwe. Zatsopanozi zikuyang'ana kwambiri pakuwonjezera kulimba, magwiridwe antchito, komanso kukhazikika. Ndizoyenera kwambiri maukonde a data omwe akukulirakulira masiku ano.
