Nyob rau hauv lub toj roob hauv pes-evolving thiab cov ntaub ntawv hloov chaw, kuj paub tias yog fiber ntau cov cable, tau tawm los ua cov tshuab cawb. Cov cable no yog tsim los xa cov paib teev dhau ntawm qhov ntev ntev nrog cov teeb liab tsis zoo, hloov kho txoj kev uas peb sib txuas lus thiab qhia cov ntaub ntawv. Txhawm rau kom paub meej txog qhov tseem ceeb ntawm cov cable optical, nws yog qhov tseem ceeb kom nkag siab lawv lub hom phiaj, lawv ua haujlwm li cas, thiab lub myriad ntawm kev thov lawv pab.
Lub hom phiaj ntawm cov khoom siv kho qhov muag
Cov ntaub ntawv kho qhov muag yog feem ntau yog siv los nqa cov cim teeb, feem ntau hauv cov qauv ntawm cov ntaub ntawv sib kis ntawm cov ceev. Tsis zoo li ib txwm tooj liab cables, uas kheev cuam tshuam rau cov hluav taws xob hluav taws xob, cov khoom siv kho kho kho qhov tshiab, suav nrog kev sib ntaus sib tua ntau dua, thiab txo qis dua rau hluav taws xob cuam tshuam.
Yuav ua li cas optical cables ua haujlwm
Qhov ntsuas kho kho qhov muag muaj cov tub ntxhais ua los ntawm iav lossis yas, puag ncig los ntawm cov cladding nrog qis dua kev ntsuas qis dua. Cov qauv tsim no tso cai rau lub teeb kom coj raws li cov tub ntxhais los ntawm cov txheej txheem ntawm kev cuam tshuam tag nrho. Thaum lub teeb pom kev zoo yog txhaj rau ib qho kawg ntawm cov fiber ntau, nws bounces tawm ntawm cladding thiab taug kev cia qhov ntev ntawm cov fiber ntau, tawm ntawm lwm qhov kawg nrog kev poob qis.
Ib hom-hom fibers, uas muaj ib tug me me core txoj kab uas hla, txhawb nqa ib hom teeb, ua rau lawv zoo tagnrho rau kev sib txuas lus ntev. Ntau hom fibers, nrog ntau cov cores loj dua, txhawb ntau hom ntawm lub teeb thiab feem ntau siv nyob rau hauv cov kev siv luv luv-deb zoo li cov chaw hauv nroog (lans).
Cov ntawv thov ntawm kho qhov muag cable
Cov ntaub pua chaw kho qhov muag muaj ntau cov kev siv, ncua ob tus neeg siv khoom thiab cov haujlwm lag luam:
Telecommunications:Qhov muag hloov kho qhov muag lub ntsej muag ntawm cov xov tooj hauv ntiaj teb, ua rau muaj kev sib txuas lus hauv ntiaj teb, lub suab sib txuas lus kom nrawm, thiab this vis. Lawv tseem ceeb heev rau kev sib txuas lus ntev ntev, xws li transatlantic fiber-optic cablese, thiab rau txuas lub nroog thiab thaj chaw hauv ib lub tebchaws.
Cov Ntaub Ntawv Chaw:Hauv cov chaw hauv cov ntaub ntawv, cov ntaub ntawv kho qhov muag tau siv los txuas cov servers, cia khoom siv, thiab khoom siv network. High-ceev fiber ntau sib txuas, xws li MTTS, yog qhov tseem ceeb rau kev tswj hwm cov ntawm cov fibers uas yuav tsum tau los txhawb kev muaj peev txheej kev sib txuas.
Cable TV:Fiber-optic cables yog siv hauv cable TV network los muab cov ntsiab lus siab thiab ultra-siab txhais cov ntsiab lus rau cov neeg. Lawv pab kom cov khoom xa tuaj ntau cov kev pabcuam thiab cov kev pabcuam nrog cov duab kos zoo thiab kev ntseeg tau.
Cov chaw hauv zos tes hauj lwm (LANS):Tsis pub dhau lub tsev lossis chaw pw, muaj ntau hom optical cables siv los tsim cov network ceev uas txuas cov khoos phis tawj, luam tawm, thiab lwm yam khoom siv. Cov kab ke no feem ntau tau nruab rau hauv cov txheej txheem kev teeb tsa, uas tso cai rau kev tswj kom yooj yim thiab nthuav dav.
Muaj Ntaub Ntawv:Cov ntaub pua chaw kho qhov muag kuj tseem siv rau hauv cov chaw muaj rau cov kev siv xws li cov txheej txheem tswj hwm, kev saib xyuas kev nyab xeeb, thiab kev nyab xeeb. Lawv txoj kev tawm tsam rau hluav taws xob kev cuam tshuam thiab muaj peev xwm los xa cov ntaub ntawv dhau mus deb ua rau lawv zoo tagnrho rau cov chaw ib puag ncig.
Kev Siv Lub Tebchaws:Raws li thov kom muaj kev kub ceev rau Internet thiab streaming streaming, fiber-rau-hauv-tsev (FTH) thev naus laus zis tau ua ntau dua. Cov ntaub pua chaw kho qhov muag tau raug teeb tsa ncaj qha rau lub tsev lossis lub tsev, muab cov ultra-ceev Internet nrawm thiab ua kom zoo dua kev sib txuas.
Cov txiaj ntsig ntawm cov khoom siv kho qhov muag
High bandwidth: Cov ntaub pua chaw kho qhov muag tuaj yeem txhawb nqa cov ntaub ntawv tus nqi deb tshaj li cov neeg tooj liab cable, ua kom cov kev sib txuas lus ceev thiab cov ntaub ntawv siab dua.
Ntev ntev:Lawv tuaj yeem xa cov phiajcim tshaj qhov ntev ntev uas tsis muaj qhov tsis zoo poob ntawm qhov zoo, ua rau lawv zoo tshaj plaws rau kev sib txuas lus ntev ntev.
Electromagnetic cuam tshuam tsis kam: cov cable kho qhov muag tsis cuam tshuam los ntawm kev cuam tshuam hluav taws xob hauv hluav taws xob.
Kev Ruaj Ntseg:Vim tias cov cim kho qhov muag yog qhov nyuaj rau coj mus rhaub lossis cuam tshuam nrog, kho qhov muag cable muaj qib siab dua ntawm kev sib txuas lus rau kev sib txuas lus.
