1. Dab tsi yog ib txwm muaj fiber ntau optic repeater?
Feem ntau, thaum tib neeg xa mus rau muaj fiber ntau receater hauv kev lag luam, lawv tau tham txog ib qho kev ntsuas fiber ntau fiber ntau.
Yuav ua li cas ua fiber ntau dua kev rov ua haujlwm?
Ib qho kev ua kom rov ua hluav taws xob fiber ntau hloov pauv cov cim txawb (RF analog paib) rau hauv cov cim optal, thiab tom qab ntawd hloov lawv rov qab mus rau RF cim tseg. Lub hauv paus ntsiab lus yog qhia hauv qab no.
Thaum lub cim analog tau hloov mus rau hauv lub teeb, qhov zoo ntawm lub teeb liab kho qhov muag tau zoo heev ntawm cov kab ke sib kis tau, feem ntau ua rau lub teeb liab distortion, suab nrov, thiab lwm yam teeb meem.
Ua haujlwm ua haujlwm ntawm fiber ntau lub cev rov ua dua tshiab
Ntxiv mus, tsoos analog fiber ntau dua optic repers feem ntau tawm tsam nrog kev tswj hwm thiab suab nrov kev ua kom haum teeb liab thiab kev ua kom zoo dua.
Piv txwv li, cov duab ntxig fiber ntau Optic Recector muaj ntau qhov kis tau ntau tshaj plaws ntawm tsuas yog 5km, thiab ntau pawg kis tau rau kev cuam tshuam rau kev cuam tshuam. Hauv cov xwm txheej nrog ntau zaus sib txuas, yog tias ob pawg muaj ntau zaus, kev cuam tshuam tau yooj yim tshwm sim thaum kis tau yooj yim thaum muaj kev kis thaum muaj kev kis tau thaum muaj kev kis tau thaum lub sijhawm kis.
Nplooj ntawv qhia txog fiber ntau fiber ntauthiab DAS
Raws li qhov tshwm sim, analogFiber Optic Recovers, uas cia siab rau cov cim analog, tsis yog txaus rau cov ntaub ntawv sib txuas lus niaj hnub no, tshwj xeeb rau cov neeg siv khoom lag luam.

2. Dab tsi yog digital fiber ntau optic repeater?
Raws li lub npe qhia, lub Digital Fiber Optic Receater yog ib qho kev hloov kho tshiab ntawm cov tsoos analog fiber ntau optic repeater. Tus txheej txheem tseem ceeb yog tias nws xub hloov kho mobile Nyob rau hauv deb kawg, cov cim qhia tau rov qab ua cov cim qhia digital thiab mam li hloov dua siab rov qab rau hauv lub xov tooj ntawm tes rau kev xa khoom rau cov neeg siv lub xov tooj. Lub hauv paus ntsiab lus yog qhia hauv qab no.
Hauv essence, lub Digital Fiber ntau Optic ReceCe ntxiv ib kauj ruam ntxiv ntawm kev hloov cov cim hauv cov ntawv digital ua ntej kis tau.
Ua haujlwm ua haujlwm ntawm Digital Fiber Optic Receater
Nyob rau hauv cov nqe lus ntawm cov cim teeb liab, digital teeb liab ua (DSP) zoo li kev sib raug zoo, txawm tias muaj cov xwm txheej ntawm kev sib raug zoo thiab kev nyab xeeb thiab kev ntseeg tau ntawm kev sib txuas lus.
Tsis tas li ntawd, digital fiber ntau cov repovers muab siab dua thiab hloov pauv tau zoo nyob rau hauv kev tswj hwm thiab zaus xaiv. Cov rov qab ua tau zoo thiab ua kom zoo rau cov teeb liab zoo raws li kev xav tau network ib puag ncig thiab kev lag luam.
3. Tsoos Cov Fiber Ntau Dua Optic Resters thiab Digital Fiber Optic Rov
| Yam zoo | Tsoos fiber ntau optic repeater | Digital Fiber Optic Receater |
| Hom phiajcim hom | Hloov cov cim taw qhia rau lub cim kho kho | Hloov RF cim rau cov cim digital, tom qab ntawd ua qhov muag |
| Teeb Liab Zoo | Nquag mus rau lub teeb liab distortion thiab suab nrov vim muaj cov fiber ntau cov kab mob kis tau | Siv DSP kom tshem tawm cov suab nrov thiab cuam tshuam, ua kom muaj kev sib cuam tshuam zoo |
| Tau Tswj | Tsis muaj zog nyob rau hauv kev tswj hwm thiab suab nrov | Muab qhov ntsuas siab thiab hloov pauv tau zoo nyob rau hauv kev tswj hwm thiab zaus xaiv |
Las sabTxoj Digital Fiber Optic Receater yog ib qho ntawm lub tuam txhab cov khoom lag luam tseem ceeb tshaj plaws. Nws txhawb nqa cov kev sib kis mus txog 8km, ua kom muaj txiaj ntsig zoo cov ntaub ntawv kis tau kom tau raws li qhov xav tau ntawm 4G thiab 5G cov ntaub ntawv hloov chaw.

4. Cov lus nug nquag:
Q1: tuaj yeem muaj cov khoom siv fiber ntau ntawm cov recogers tau hloov kho mus rau digital fiber ntau optic rov hais dua?
A:
-Koj tuaj yeem khaws cov khoom siv fiber ntau thiab kav hlau txais xov, tsuas yog hloov cov qauv tseem ceeb relay.
-A Cov teeb liab kev teeb liab ua (DSP) yuav muab ntxiv rau kev sib raug zoo nrog tus thawj RF.
-Cov tus nqi hloov kho tshiab tuaj yeem txo los ntawm 40% -60%, ua kom koj txoj kev tiv thaiv koj txoj kev nqis peev.
1.Yog thawj lub network tsim qauv siv lub hnub qub kev sib txuas, tsuas yog hloov cov analog repeater nrog cov kav hlau txais xov xwm thiab kho cov tshuaj tiv thaiv tshwj xeeb yuav ua rau muaj kev txaus.
2. hwm lwm cov kev teeb tsa network, qee cov khoom siv fiber ntau ntxiv hloov kho yuav tsim nyog. Yog tias koj xav paub txog kev txhim kho rau cov fiber ntau fiber ntau optic repeater, xav tiv tauj peb. Peb cov kws sib txuas sib txuas lus yuav muab koj cov kev daws teeb meem zoo tshaj plaws.
Q2: Puas yog cov digital rov ua haujlwm yuav tsum tau koom tes los ntawm cov neeg ua haujlwm ntawm tes hauj lwm mobile network?
