Lub ntsuas hluav taws xob kho kho kho kho kho kho kho kho kho kho tau zoo yog eternet xa xov xwm hloov pauv uas sib pauv cov cim hluav taws xob luv luv-khub hluav taws xob. Nws tseem hu ua cov xov tooj sib hloov hauv ntau qhov chaw. Cov khoom lag luam feem ntau yog siv nyob rau hauv cov chaw etherpet tsis tuaj yeem siv tau los txuas ntxiv txheej txheej txheem kev sib tw, thiab feem ntau yog qhov chaw nkag mus rau txheej txheej ntawm kev nkag mus ntawm thaj chaw dav dav.
Lub luag haujlwm ntawm cov kev hloov fiber ntau optic
Muaj cov kev hloov hluav taws xob muaj hluav taws xob muaj hluav taws xob feem ntau siv hauv cov chaw etherpet yuav tsis tuaj yeem siv thiab kho qhov muag kho qhov kev ncua deb. Nyob rau tib lub sijhawm, lawv kuj tau ua lub luag haujlwm tseem ceeb hauv kev pab txuas lub mais kawg ntawm cov kab hluav taws xob kho qhov muag mus rau thaj chaw hauv nroog thiab cov chaw sab nraud. Lub luag haujlwm ntawm. Txoj haujlwm ntawm cov fiber ntau transic transceer yog kom hloov hluav taws xob hluav taws xob peb xav xa mus rau hauv lub teeb liab kho tshiab thiab xa nws tawm. Nyob rau tib lub sijhawm, nws tuaj yeem hloov kho qhov teeb liab kho qhov muag mus rau hauv cov cim hluav taws xob thiab cov lus qhia rau peb qhov kev tau txais.
NtawmFiber Optic Transceivers
1.Single-hom fiber ntau optic transcerus: kev sib kis nrug ntawm 20 km luv mus rau 120 km.
2.Multimode Fiber ntau Optic TransceCer: Kis nrug deb ntawm 2 km rau 5 km.
Piv txwv li, lub zog hluav taws xob ntawm lub 5km fiber ntau ectsic optic transic transcerent yog feem ntau ntawm -20 thiab -14db, thiab cov uas tau txais kev rhiab heev yog -30dB, siv lub yoj taw ntawm 1310Nm; Thaum lub sijhawm xa hluav taws xob ntawm 120km fiber ntau optic transciver feem ntau ntawm -5 thiab 0db, thiab cov kev tau txais kev rhiab rau -38dB, siv lub yoj ntawm 1550nm.
Cov nta ntawm cov pa roj fiber heev optic transmiversivers
Fiber ntau optic transciversivers feem ntau muaj cov yam ntxwv yooj yim hauv qab no:
1. Muab cov ntaub ntawv muaj txiaj ntsig latences.
2. Tag nrho pob tshab rau cov txheej txheem rau network.
3. Siv cov tshuaj lom neeg mob siab rau kom paub cov ntaub ntawv kab-nrawm. Programmable ASIC concentrates ntau lub zog ntawm ib nti, thiab muaj qhov zoo ntawm kev tsim qauv yooj yim, kev ntseeg siab, thiab kev siv hluav taws xob tsawg, uas tuaj yeem pab cov cuab yeej kom tau txais kev ua tau zoo dua thiab qis dua.
4. Cov cuab yeej siv suab hom tuaj yeem muab cov haujlwm kub-Swappable rau kev kho kom yooj yim txij nkawm thiab kev hloov pauv tsis tau.
5. Cov cuab yeej tswj nruab nrab tuaj yeem muab cov haujlwm xws li kev kuaj mob network, kev kuaj mob, cov xwm txheej tshaj tawm, tsis muaj peev xwm tswj hwm lub sijhawm ua haujlwm tiav thiab muaj peev xwm ua haujlwm tiav.
6. Feem ntau cov khoom siv tau txais cov cuab yeej siv hluav taws xob, txhawb nqa cov fais fab hluav taws xob dav dav, thiab paub cov kev tiv thaiv hluav taws xob thiab hloov hluav taws xob.
7. Pab txhawb kev ua haujlwm ultra-kub ntau.
8. Txhawb kev sib nrug ua tiav (0 ~ 120 kilometers).
Qhov zoo ntawm kev hloov fiber ntau optic transciversivers
Thaum nws los txog rau cov pa roj fiber optic optic transceivers, cov neeg feem ntau zam tsis tau muaj fiber ntau optic transcesivers nroghloovnrog kho qhov muag. Cov hauv qab no tsuas yog tham txog qhov zoo ntawm fiber ntau optic transcenivers dhau ntawm qhov chaw nres nkojhloov.
Ua ntej tshaj plaws, tus nqi ntawm fiber ntau optic transcepivers plus ib txwmhloovyog pheej yig dua qhov kho qhov muaghloov, tshwj xeeb tshaj yog ib co kho qhov muaghloovYuav poob ib lossis txawm tias muaj ob peb lub chaw nres hluav taws xob tom qab ntxiv kho qhov muag, uas tuaj yeem ua rau cov neeg ua haujlwm mus rau ib qho kev nqis peev ntau ntxiv.
Thib ob, vim tias feem ntau ntawm cov hloov kho kho ntawm lubhloovTsis muaj tus qauv sib koom ua ke, ib zaug cov qauv hloov kho tau puas tsuaj, lawv yuav tsum tau hloov teeb meem tom qab. Ntawm sib txawv cov tuam txhab ntawm cov kev hloov fiber ntau, yog li nws puas lawm, nws tuaj yeem hloov nrog lwm cov khoom lag luam cov khoom lag luam, uas yooj yim heev los tswj.
Tsis tas li ntawd, cov kev hloov pauv hluav taws xob muaj ntau dua muaj ntau cov khoom lag luam tiav dua li kho chaw nres nkojhloovNyob rau hauv cov nqe lus ntawm kev sib nrug deb. Ntawm chav kawm, lub qhov muaghloovKuj tseem muaj cov txiaj ntsig zoo hauv ntau qhov, xws li kev tswj hwm kev ywj pheej thiab sib koom ua ke.
