1. Optical fiber yog qhov nruab nrab nyias thiab mos uas xa cov kab teeb ci. Feem ntau cov fibers kho qhov muag yuav tsum tau coated nrog ob peb txheej ntawm cov txheej txheem tiv thaiv ua ntej siv, thiab cov coated cable yog hu ua fiber optic cable. Yog li ntawd, cov khoom siv kho qhov muag fiber ntau yog qhov tseem ceeb ntawm cov khoom siv kho qhov muag, thiab cov khoom siv kho qhov muag ua rau cov khoom siv kho qhov muag los ntawm kev tiv thaiv qee cov khoom thiab cov txheej txheem tiv thaiv.
Cov qauv kev tiv thaiv ntawm txheej txheej ntawm cov khoom siv kho qhov muag tuaj yeem tiv thaiv ib puag ncig ib puag ncig los ntawm kev puas tsuaj rau cov khoom siv fiber ntau. Optical cables muaj xws li optical fibers, tsis khaubncaws sab nraud povtseg thiab cladding. Fiber optic thiab coaxial cables zoo sib xws, tsuas yog tsis muaj cov ntaub thaiv npog mesh. Ntawm qhov chaw yog lub iav core qhov twg lub teeb mus.
Optical fibers feem ntau yog bundled thiab tiv thaiv los ntawm ib tug casing. Cov tub ntxhais fiber ntau feem ntau yog ob txheej txheej concentric lub tog raj kheej ua los ntawm quartz iav nrog rau thaj tsam me me, uas yog nkig thiab yooj yim tawg, yog li yuav tsum muaj txheej tiv thaiv sab nraud. Yog li ntawd qhov txawv ntawm lawv.
2. Optical fiber cable: Nws yog tsim los ntawm fiber ntau optical (iav filament raws li nyias raws li cov plaub hau), lub tes tsho tiv thaiv yas thiab yas txheej tawv nqaij. Tsis muaj hlau xws li kub, nyiaj, tooj liab thiab txhuas nyob rau hauv optical cable, thiab feem ntau tsis muaj nqi rov ua dua. Optical cable yog hom kev sib txuas lus uas muaj qee tus xov tooj ntawm cov khoom siv kho qhov muag tsim cov tub ntxhais cable raws li ib txoj hauv kev, uas yog npog nrog lub tsho, thiab qee qhov kuj tau them nrog lub tsho sab nrauv kom paub txog qhov muag pom kev sib kis. Ntawd yog, qhov kho qhov muag cable yog tsim los ntawm optical fiber (optical transmission carrier) los ntawm ib qho txheej txheem.
Qhov zoo ntawm optical cable Optical fiber cable yog ib tiam tshiab ntawm kev sib kis nruab nrab. Piv nrog rau tooj liab nruab nrab, fiber ntau optical tau zoo heev nyob rau hauv cov nqe lus ntawm kev ruaj ntseg, kev cia siab rau thiab kev ua tau zoo network. Lub bandwidth ntawm optical fiber ntau kis tau tus mob ntau tshaj li ntawm cov tooj liab cable, thiab qhov siab tshaj plaws kev txhawb nqa yog ntau tshaj li ob kilometers. Optical fiber cable muaj qhov zoo ntawm qhov zoo ntawm electromagnetic cuam tshuam tsis kam, muaj zog tsis pub lwm tus paub, ceev ceev thiab muaj peev xwm kis tau tus mob loj.
Tam sim no, muaj ob hom kev kho qhov muag fiber ntau uas muaj ntau dua, uas yog ib hom optical fiber ntau thiab ntau hom optical fiber ntau. Multimode fiber ntau feem ntau yog siv rau kev sib txuas hauv network hauv tib lub tsev ua haujlwm lossis hauv thaj chaw ze. Ib hom fiber ntau, ntawm qhov tod tes, xa cov ntaub ntawv zoo dua thiab ntev dua, thiab feem ntau yog siv los txuas cov tes hauj lwm ntawm cov tsev ua haujlwm lossis ntau thaj chaw sib cais. Yog hais tias lub optical fiber cable siv los ua lub network kis nruab nrab, nws yog ib qho tsim nyog yuav tau ntxiv cov khoom xws li optical transceivers.
