Taw qhia
Optical cables, tseem hu ua fiber optic cables, tau dhau los ua neeg nyiam ntau xyoo dhau los vim lawv muaj peev xwm xa cov ntaub ntawv ntawm kev kub ceev thiab nyob ntev. Cov cables tam sim no tau siv ntau yam kev siv, suav nrog kev sib txuas lus, cable TV, thiab kev sib txuas hauv internet. Nyob rau hauv tsab xov xwm no, peb yuav tshawb txog dab tsi optical cables yog dab tsi, lawv ua haujlwm li cas, thiab lawv cov kev siv ntau yam.
Dab tsi yog optical cable?
Ib qho khoom siv kho qhov muag yog ib hom cable uas muaj ib los yog ntau dua fibers, uas yog nyias nyias ntawm iav los yog yas uas nqa lub teeb liab. Lub hom phiaj tseem ceeb ntawm lub cable yog xa cov teeb liab teeb pom kev deb, cia cov ntaub ntawv xa mus sai thiab ua tau zoo.
Optical cables ua haujlwm li cas?
Optical cables ua haujlwm los ntawm kev xa cov teeb liab los ntawm fibers. Lub teeb pom kev zoo yog tsim los ntawm laser lossis LED thiab tom qab ntawd xa los ntawm fiber ntau, thaws tawm ntawm phab ntsa ntawm fiber ntau thaum lawv taug kev raws nws qhov ntev. Cov txheej txheem no, lub npe hu ua tag nrho cov kev xav sab hauv, ua kom lub teeb pom kev hauv cov fiber ntau, tso cai rau nws kis tau mus ntev yam tsis muaj kev cuam tshuam ntau.
Qhov zoo ntawm optical cables
Optical cables muaj ntau yam zoo dua lwm hom cables, xws li tooj liab cables. Thawj qhov zoo ntawm optical cables muaj xws li:
- High bandwidth: Optical cables tuaj yeem xa cov ntaub ntawv ntawm qhov nrawm heev, ua rau lawv zoo tagnrho rau cov ntawv thov uas xav tau cov ntaub ntawv hloov pauv ceev, xws li kev sib txuas hauv internet thiab cable TV.
- Kev sib kis tau ntev: Cov kab hluav taws xob kho qhov muag tuaj yeem xa cov ntaub ntawv hla qhov deb heev yam tsis muaj teeb liab poob ntau, ua rau lawv xaiv zoo tshaj plaws rau cov ntawv thov uas xav tau cov teeb liab kis tau ntau pua lossis ntau txhiab mais.
- Kev tiv thaiv kev cuam tshuam: Optical cables tiv thaiv electromagnetic cuam tshuam, uas tuaj yeem ua rau lub suab nrov thiab teeb liab degradation hauv lwm hom cables.
- Kev ruaj ntseg: Optical cables nyuaj rau coj mus rhaub rau hauv, ua rau lawv xaiv qhov zoo tshaj plaws rau cov ntawv thov uas xav tau kev ruaj ntseg siab.
Kev siv ntawm optical cables
Optical cables yog siv nyob rau hauv ntau yam kev siv, xws li:
- Kev Sib Txuas Lus: Cov kab hluav taws xob kho qhov muag yog cov caj qaum ntawm cov kev sib txuas lus niaj hnub no, nqa cov ntaub ntawv ntau dhau ntawm cov nroog thiab lub tebchaws.
- Cable TV: Optical cables yog siv los xa cov xov tooj cua TV rau cov tsev thiab cov lag luam, muab cov yeeb yaj kiab thiab suab zoo.
- Kev sib txuas hauv Is Taws Nem: Cov kab hluav taws xob kho qhov muag tau siv dav los muab kev sib txuas hauv internet ceev, nrog fiber ntau-rau-lub tsev (FTTH) ua nrov nrov hauv ntau qhov chaw hauv ntiaj teb.
- Cov khoom siv kho mob: Cov khoom siv kho qhov muag tau siv ntau yam khoom siv kho mob, xws li endoscopes, qhov chaw uas lawv tso cai rau cov kws kho mob saib cov kab mob hauv nruab nrog cev yam tsis tas yuav muaj kev phais mob.
- Cov ntawv thov kev lag luam: Optical fibers yog siv rau hauv ntau daim ntawv thov kev lag luam, xws li kev paub thiab kev saib xyuas, qhov chaw uas lawv tuaj yeem ntsuas qhov ntsuas tsis zoo xws li qhov kub thiab txias, siab, thiab lim nrog qhov raug siab.
Hom ntawm optical cables
Muaj ntau ntau hom optical cables, suav nrog:
- Ib hom fiber ntau: Hom fiber ntau no yog siv rau kev siv mus ntev thiab tuaj yeem xa cov teeb liab hla mus txog 100 km yam tsis muaj teeb meem ntau.
- Ntau hom fiber ntau: Hom fiber ntau no yog siv rau kev siv luv luv thiab tuaj yeem xa cov teeb liab hla mus txog 2 km ua ntej teeb liab poob los ua teeb meem.
- Plastic optical fiber (POF): POF yog ib hom fiber ntau optical uas siv cov yas hloov iav, ua rau nws tsis tshua muaj nqi rau kev tsim khoom. Nws feem ntau yog siv nyob rau hauv qis-ceev, luv luv daim ntaub ntawv.
Xaus
Optical cables tau dhau los ua ib qho tseem ceeb hauv ntau lub tshuab kev sib txuas lus niaj hnub no, muab cov ntaub ntawv xa mus sai thiab ua haujlwm tau zoo nyob rau qhov ntev. Nrog rau qhov nce hauv kev thov rau kev sib txuas hauv internet ceev thiab nce hauv internet-of-things (IoT) cov khoom siv, kev siv cov kab hluav taws xob kho qhov muag xav tau txuas ntxiv mus ntxiv rau yav tom ntej. Txawm hais tias koj tab tom siv internet, saib cable TV, lossis tau txais kev kho mob, yuav muaj feem cuam tshuam tias cov kab hluav taws xob kho qhov muag tau ua lub luag haujlwm tseem ceeb hauv cov thev naus laus zis uas koj siv.
