Kho qhov muag tau kho qhov muag tuaj yeem xa cov paib uas pom zoo li analog cov cim. Tam sim no, 90% ntawm lub ntiaj teb kev pabcuam sib txuas lus yuav tsum tau txais kev kho kho ntawm cov neeg kho muag. Nrog rau kev txhim kho cov fiber ntau cov kev sib txuas lus siv lub ntiaj teb tau tshaj tawm cov khoom siv fiber ntau rau hauv kev sib txuas lus sib txuas lus hauv zej zog, relay networks, thiab kev siv tes ua haujlwm.
Fiber Optic Broadband xov tooj txuas thiab kev siv tes ua haujlwm tau txhim kho kom sai thiab yog lub hom phiaj tseem ceeb ntawm kev tshawb fawb tam sim no, kev txhim kho, thiab kev thov. Ntau cov kev siv ntawm fiber ntau sib txuas lus tuaj yeem sau tau li cas raws li hauv qab no:
(1) Kev sib txuas lus tes hauj lwm: Fiber Optic Sib Txuas Lus hauv kev sib txuas lus thiab tau dhau los ua cov kev sib txuas lus hauv niaj hnub no. Txij li thaum muaj fiber ntau cov tshuab sib txuas lus tuaj yeem muaj cov dej hiav txwv tsis ntev los no, thiab cov dej hiav txwv uas muaj qhov sib cuam tshuam nrog cov dej hiav txwv Atlantic thiab Pacific Thawj fiber ntau cov kev sib txuas lus zoo thoob plaws ntawm Atlantic (Tat-8) pib tau pom ntawm thawj zaug ntawm thawj lub xov tooj tooj liab cig (Tat-1).
Lub tat - 8 fiber optic kev sib txuas lus sib xws ntawm Tebchaws Asmeskas thiab Europe, ua rau muaj kev sib txuas lus ntawm Tebchaws Asmeskas Piv nrog coaxial cable, cov cable kho qhov muag muaj ntau dua hauv qhov hnyav, ua rau lawv thauj thiab nteg. Ntxiv mus, yog tias qis - poob optical fibers thiab kev xav tau ntawm cov rov ua dua tshiab tuaj yeem txo lossis tshem tawm. Tam sim no, muaj cov khoom siv kho qhov muag txhua qhov thiab dej hiav txwv feem ntau ntawm lub ntiaj teb, ua cov choj nrawm nrawm txuas ntxiv txuas ntxiv txuas ntxiv.
Pej xeem Telecommunications ntawm ntau lub tebchaws. Qhov tseeb kho qhov muag tau muaj qhov zoo me me thiab cov ntaub ntawv muaj peev xwm loj tshaj plaws rau cov tooj liab zoo tshaj plaws rau cov tub tooj liab ib txwm muaj nyob rau hauv theem tam sim no. Tuam Tshoj lub teb chaws ua ntej {}}} Cov kab hauv nroog, thiab cov kab lis kasch hauv qab lub nroog lub nroog tau hloov mus rau cov kho mob kho mob.
Ntau yam kev sib txuas lus tshwj xeeb. Siv hluav taws xob fiber ntau siv rau kev sib txuas lus, kev soj ntsuam hauv hluav taws xob muaj kev cuam tshuam ntawm cov khoom siv hluav taws xob thiab lwm yam kev sib kis lub sijhawm thiab kev txais tos ntawm video.
Kev Sib Txuas Lus Tshwj Xeeb. Qhov muag muag muag muag tau muaj zog heev corrosion tsis kam, thiab siv cov khoom siv kho qhov muag thiab cov tshuaj tua kab mob loj thiab lwm lub chaw haujlwm muab kev nyab xeeb dua.
Kev siv cov fiber ntau nws nws cov kev sib txuas lus sab hauv dav hlau, kev sib tua ntawm cov cim ntawm cov kabmob, thiab cov cuaj luaj, thiab tsis muaj teeb meem hluav taws xob, thiab tsis muaj teeb meem hluav taws xob.
(2) Thaj chaw hauv zos thiab thaj chaw dav dav network uas tsim kho Internet tshwj xeeb yog tsim nyog rau cov ntaub ntawv sib txuas hauv cov ntawv digital. Kev sib txuas ua ke ntawm kev ua hwm hauv nruab nrab (CPUS) thiab cov khoom siv hluav taws xob, nruab nrab ntawm CPUS thiab lub cim xeeb, thiab nruab nrab ntawm ntau qhov CPUs txhua tus tuaj yeem paub txog siv kho qhov muag. Qhov kis tau tus nqi ntawm thaj chaw hauv nroog thiab thaj chaw dav siv cov khoom siv kho tshiab tau nce ntxiv rau 100 si6 5}} Kev sib txuas nrawm ntawm thaj chaw hauv nroog. Cov khoom siv ntsuas kho qhov muag tau siv rau thaj chaw hauv cheeb tsam thiab thaj chaw dav nrog ntau yam sib txawv ntawm cov tub sab.
(3) Cov pob tw thiab xa tawm cov network ntawm Cable TV network, kev tshaj tawm hauv TV, thiab tus kheej {1} {1} {1} {1} {1} {1} {1} {1} {1} Nplooj duab Kho qhov muag tau kho qhov muag tuaj yeem sib txuas ncaj qha rau cov ntawv xa tawm video ntawm cov neeg siv davhlau ya nyob twg. Ntau lub TV ntau zaus tuaj yeem sib kis ib txhij siv ntau txoj kev kho qhov muag tau cais nyob rau hauv ib qho kev kho qhov muag lossis los ntawm zaus faib multiplexing ntawm ib lub ntsuas hluav taws xob ib zaug. Cov kev sib txuas lus fiber ntau qhib tau rau cov ntaub ntawv kis tau, cov tsev txhab nyiaj, chaw nres tsheb, thiab cov chaw tsheb thauj mus los, thiab pej xeem kev ruaj ntseg.
(4) Kev Pab Cuam Nruab Nruab Nruab Nrab Optical Cov Network: Muab cov ntaub ntawv siv rau cov xov tooj tseem ceeb thiab cov yeeb yaj kiab, muab ntau yam kev pabcuam hauv zej zog.
(5) Kev Ntsuas Hluav Taws Xob Txawm li cas los xij, kho qhov muag fiber ntau sensors yog ib qho tseem ceeb tshaj daim ntawv thov ntawm Fiber ntau Optics. Kev ntsuas kho qhov muag tau ua tiav tau ua tiav cov teb xws li ntsuas kub, ntsuas siab, ntsuas txoj kev ntsuas siab, ntsuas kev ua kua tob. Rau qee qhov sensors, kho qhov muag tau muaj dual lub zog: Ua ntej, lub sensor nws tus kheej yog nyob ntawm qee cov yam ntxwv ntawm cov khoom siv kho tshiab; Qhov thib ob, cov ntaub ntawv yog sau thiab kis los ntawm kev siv cov fiber ntau rau cov ntaub ntawv cov ntaub ntawv tawm tswv yim.
Daim ntawv thov tseeb ntawm no peculiar nruab nrab ntawm cov xov tooj ntawm cov xov tooj thiab cov nqi txo rau cov khoom siv tooj liab, tab sis Network Pressiving Network tseem muaj cov qauv kev sib txuas lus muaj fiber ntau. Lub peev xwm ntawm fiber ntau sib txuas lus tsis tau pom meej, thiab cov ntawv thov ntawm fiber ntau cov kev sib txuas lus technology hauv cov ntawv sib txuas lus tam sim no tseem yog daim ntawv thov classical. Nrog tus qauv ntawm txhua - Kev sib txuas lus kho qhov muag tau txiav tawm rau cov cim hluav taws xob, yog li kev tswj hwm tau ua tiav hauv kev sib txuas lus Fiber ntau cov kev sib txuas lus.
