Peb C's ntawm Optical Fiber
Cov ntsiab lus tseem ceeb ntawm fiber ntau optical nyob rau hauv cov nqe lus ntawm kev kuaj fiber ntau yog qee zaum hu ua "peb C's":
Core:Qhov chaw ntawm lub fiber ntau cable, ua los ntawm tshwj xeeb kho iav los yog yas. Qhov no yog qhov nruab nrab rau lub teeb kis tau tus mob thoob plaws qhov ntev ntawm lub cable, yog li nws yuav tsum ua kom huv thiab huv li sai tau.
Cladding:Ib txheej ntxiv ua los ntawm cov khoom siv zoo ib yam li cov tub ntxhais, tab sis nrog qhov qis dua qhov taw qhia kom pab txhawb qhov kev xav tsis tu ncua ntawm lub teeb ci rov qab mus rau hauv cov tub ntxhais.
Txheej:Lub txheej txheej ntawm lub cable uas qhwv, tiv thaiv, thiab insulates cov tub ntxhais thiab cladding.
Hom Fiber
Fiber ntau tau muab faib ua ntau hom (multimode lossis ib hom) raws li txoj hauv kev uas lub teeb mus los ntawm nws. Hom fiber ntau zoo sib xws nrog txoj kab uas hla ntawm cov tub ntxhais thiab cladding. Multimode fiber ntau muaj ib txoj kab uas hla loj dua uas tso cai rau ntau hom teeb kom dhau los ntawm nws ib txhij.
Lub hom phiaj tseem ceeb ntawm multimode fiber ntau yog qhov yooj yim ntawm kev sib txuas rau lub teeb ci thiab rau lwm cov fibers, cov nqi qis dua lub teeb (transmitters), thiab yooj yim connectorization thiab splicing txheej txheem. Txawm li cas los xij, nws qhov siab attenuation (optic poob) thiab qis bandwidth txwv qhov kev sib kis ntawm lub teeb hla multimode fiber ntau mus rau luv luv.
Qhov kom zoo dua ntawm ib hom fiber ntau yog nws cov kev ua tau zoo dua nrog kev hwm rau bandwidth thiab attenuation.
Cov tub ntxhais me me ntawm ib hom fiber ntau yuav tsum tau kim dua transmitters thiab cov kab ke sib dhos kom ua tau zoo sib txuas. Txawm li cas los xij, rau cov tshuab ua haujlwm siab lossis rau cov tshuab uas ntev tshaj li ob peb kilometers, ib hom fiber ntau tseem yog qhov kev xaiv zoo tshaj plaws.
