Fiber ntau opticKev sib txuas lus tau siv dav hauv kev sib txuas lus sib txuas lus thiab tau dhau los ua txoj hauv kev tseem ceeb hauv kev sib txuas lus niaj hnub no.
Ntiaj teb no kev sib txuas lus Network
Vim tias qhov sib txawv ntawm qhov ntev ntev tuaj yeem ua tau nyob rau hauv kev sib txuas lus fiber ntau, nws muaj peev xwm tsim submarine optical fiber ntau txoj kev hla dej hiav txwv, xws li submarine optical cables hla Atlantic thiab Pacific Oceans, thiab transcontinental optical cable trunk kab hla Eurasian sab av loj. Thawj qhov kev sib txuas lus fiber ntau thoob plaws hauv Atlantic (TAT-8) tau qhib thiab muab tso rau hauv qhov kawg ntawm 1988, uas tau ua tiav 32 xyoo tom qab thawj coaxial cable xov tooj system (TAT-1) tau qhib. Lub TAT-8 optical fiber kev sib txuas lus yog kwv yees li 6 × 10³km ntawm sab hnub tuaj ntug dej hiav txwv ntawm Tebchaws Meskas thiab Tebchaws Europe, thiab tuaj yeem muab tag nrho lub peev xwm ntawm ze li ntawm 40,000 lub suab channel, ua kom pom qhov zoo tshaj ntawm kev sib txuas lus fiber ntau hauv cov ntsiab lus ntawm lub peev xwm. Piv nrog cov coaxial cables, optical cables yog qhov sib dua ntawm qhov hnyav, ua rau lawv yooj yim rau kev thauj thiab nteg. Ntxiv mus, yog siv cov fibers optical nrog qis poob thiab optical amplifiers, qhov kev xav tau ntawm cov repeaters tuaj yeem raug txo lossis tshem tawm. Tam sim no, muaj optical cables nyob rau hauv tag nrho cov dej hiav txwv thiab feem ntau ntawm lub ntiaj teb no seas, tsim high-ceev kev sib txuas lus choj.
Public telecommunication networks ntawm ntau lub teb chaws
Optical cables muaj qhov zoo ntawm qhov me me thiab cov ntaub ntawv loj, thiab yog li ntawd tau dhau los ua lwm txoj hauv kev zoo tshaj plaws rau cov tsoos tooj liab hlau cables nyob rau theem no. Tuam Tshoj tus thawj lub teb chaws thawj - theem pob tw kab, lub xeev thib ob - cov kab hauv kab, thiab cov kab feeder hauv qab lub nroog yog qhov tseem ceeb ntawm fiber ntau -optic.
Ntau yam kev sib txuas lus tshwj xeeb
Optical fiber systems siv los ntawm hluav taws xob fais fab, kev tsheb ciav hlau, kev tiv thaiv lub teb chaws thiab lwm lub tuam tsev rau kev sib txuas lus, hais kom ua, xa, thiab kev saib xyuas feem ntau yog siv cov electromagnetic cuam tshuam tsis kam ntawm optical fibers xa thiab tau txais cov teeb liab video hauv lub sijhawm.
Kev sib txuas lus tshwj xeeb
Optical fibers muaj zog corrosion kuj, thiab siv optical cables nyob rau hauv flammable thiab explosive ib puag ncig nyob rau hauv roj av, tshuaj, thee mining thiab lwm yam departments muab kev ruaj ntseg dua.
Lwm yam kev sib txuas lus
Aircraft, warships, submarines, missiles thiab spacecraft siv optical fiber kev sib txuas lus nyob rau hauv, siv cov yam ntxwv ntawm optical fibers yog lub teeb yuag, me me ntim, electromagnetic cuam tshuam resistant, thiab tsis muaj teeb liab hluav taws xob.
