Ib qho ntawm ntau yam uas ua rau fiber ntau optic Internet zoo dua yog tias nws muab qhov nrawm nrawm, txhais tau tias nws rub tawm thiab rub nrawm nrawmDSL thiab lwm hom Is Taws Nem, tsuas yog muab asymmetrical speeds, qhov twg download speeds sai dua upload dua upload speeds.
Vim li cas fiber internet sai dua?
Fiber optic Internet siv txiav ntug tshuab. Cov ntaub ntawv raug xa los ntawm cov iav me me, hloov tau yooj yim ntawm cov iav uas xa lub teeb. Qhov no tso cai rau cov ntaub ntawv xa mus sai dua nyob deb dua.
Puas yog fiber-optic internet ceev tshaj?
Fiber tam sim no yog hom kev siv internet ceev tshaj plaws, nrog nrawm txog 10,000 Mbps hauv ob peb thaj chaw. Nws siv cov iav fiber ntau-optic threads bundled ua ke los hloov lub teeb pom kev, uas yog ceev thiab txhim khu kev qha nyob ntev. Fiber tsis cuam tshuam los ntawm cov teeb meem ceev uas tshwm sim hauv cov laus ntawm kev sib txuas hauv internet.
Vim li cas fiber ntau optical muaj qhov ceev tshaj plaws?
Fiber-optic bandwidth siab ob qho tib si vim qhov nrawm uas cov ntaub ntawv tuaj yeem xa mus thiab qhov kev ncua deb uas cov ntaub ntawv tuaj yeem taug kev yam tsis muaj kev cuam tshuamOptical fiber xa cov ntaub ntawv raws li cov pulses ntawm lub teeb los ntawm iav hlau, tso cai rau cov ntaub ntawv mus rau ze li ntawm qhov ceev ntawm lub teeb.
Vim li cas fiber-optic sai dua Ethernet?
Fiber optic cables kuj yog ruaj ntseg dua Ethernet cables, vim tias hackers tsis tuaj yeem cuam tshuam cov ntaub ntawv ntawm qib kho vajtse, tiv thaiv koj cov ntaub ntawv hauv kev thauj mus los. Fiber optics tuaj yeem xa cov ntaub ntawv ntau dua sai dua thiab ntseeg tau ntau dua li cov xov tooj tooj liab, ua kom muaj kev nyab xeeb dua, nrawm, thiab txhim khu kev qha Internet rau tsev thiab kev lag luam.

Vim li cas kev sib txuas sib txuas yog qhov tseem ceeb?
Cov lattice reciprocal plays lub luag haujlwm tseem ceeb hauv kev tshawb fawb feem ntau ntawm cov qauv ntu, tshwj xeeb hauv kev xav ntawm kev sib txawv. Nyob rau hauv neutron thiab X-ray diffraction, vim yog Laue tej yam kev mob, qhov sib txawv ntawm cov khoom xa tuaj thiab cov duab hluav taws xob sib txawv ntawm cov siv lead uayog cov kab lattice vector .
Puas kev sib txuas lus tsis zoo kuj yog ib qho khoom ntawm kev sib txuas lus?

Dab tsi yog qhov ceev dua cable lossis fiber ntau optics?
Fiber-optic internet kev pabcuam yog nrawm dua piv rau cable network nrog qhov nrawm tsis tsawg dua 250-1,000 Mbps hauv ob qho kev qhia . Puas yog fiber ntau lossis cable Internet zoo dua? Cable thiab fiber ntau yog ob qho tib si kev sib txuas hauv internet uas txhim khu kev qha thiab tuaj yeem ncav cuag gigabit ceev (1,000 Mbps), tab sis fiber ntau yog qhov zoo dua rau kev xa cov nrawm tshaj plaws, tshwj xeeb tshaj yog rau kev xa tawm bandwidth.
Vim li cas kev sib txuas lus yog kev sib cuam tshuam?
Txhua tus neeg pom lwm tus tus cwj pwm thiab muab lub ntsiab lus rau qee qhov ntawm nws. Cov kev coj cwj pwm uas lub ntsiab lus raug muab los ua cov lus. … Hauv kev sib cuam tshuam, txhua yam koj ua lossis tsis ua yog sib txuas lus ib co lus .
Nyob rau hauv ib qho kev tsis sib haum xeeb pn kev sib tshuam cov kev sib tshuam tam sim no ntawm qhov sib npaug yog?
Nyob rau hauv qhov tsis ncaj ncees PN-kho qhov kev sib tshuam tam sim no ntawm qhov sib npaug yog zero, vim tias sib npaug tab sis cov neeg nqa khoom hla hla kev sib tshuam . Thaum pn kev sib tshuam tsis ncaj ncees qhov kev sib tshuam tam sim no ntawm qhov sib npaug yog?
