Fiber-optic Ethernet thev naus laus zis yog kev sib koom ua ke thiab kev txhim kho ntawm ob lub ntsiab lus tseem ceeb hauv kev sib txuas lus, uas yog Ethernet thiab optical networks.It tsom rau qhov zoo ntawm Ethernet thiab optical networks, xws li kev siv Ethernet ntau, tus nqi qis, kev sib txuas yooj yim, kev tswj xyuas yooj yim, siab. kev cia siab rau thiab muaj peev xwm loj ntawm optical networks.
Kev kub ceev thiab muaj peev xwm loj ntawm optical Ethernet tshem tawm cov bandwidth bottleneck uas twb muaj lawm ntawm LAN thiab WAN, dab yuav dhau los ua ib qho kev sib txuas lus rau kev sib txuas lus, cov ntaub ntawv thiab yees duab yav tom ntej. Ethernet pob ntawv tawm tswv yim siv Ethernet li.Tam sim no, fiber-optic Ethernet tuaj yeem ua tiav cov qauv Ethernet ceev ntawm 10Mbps, 100Mbps, thiab 1Gbps.
Fiber-optic Ethernet pab kiag li lawm yog raws li txheej 2 LANhloov, Txheej 3 LANhloov, SONET li, thiab DWDM.Qee lub tuam txhab tau tsim fiber ntau-optic Ethernethloovuas muaj ntau yam nta los xyuas kom meej qhov zoo tshaj plaws kev pab cuam (xws li pob ntawv sorting thiab congestion tswj).Cov khoom no yuav xav tau cov nram qab no tseem ceeb technologies thiab nta: muaj kev ntseeg siab, siab port ceev, thiab zoo guarantees.Fiber- optic Ethernet yog kev lag luam ntau dua thiab muaj txiaj ntsig zoo dua li lwm cov kev sib txuas hauv broadband, tab sis txog tam sim no nws tau siv tsuas yog hauv cov tsev ua haujlwm lossis cov tsev uas twb muaj fiber ntau lawmCov tswv yim tus nqi ntawm txoj hauv kev tshiab no siv Ethernet tsis txwv rau kev siv pheej yig. Nws tuaj yeem siv tau ob qho tib si rau kev nkag mus rau hauv tes hauj lwm thiab rau cov pob txha caj qaum hauv zos hauv cov chaw muab kev pabcuam network.Nws tuaj yeem siv tau tsuas yog ntawm Txheej 2 lossis yog txoj hauv kev zoo los siv cov txheej txheem 3. Nws tuaj yeem txhawb nqa IP, IPX thiab lwm yam kev cai ib txwm muaj. Ntxiv rau, vim tias nws tseem yog LAN nyob rau hauv qhov xwm txheej, nws tuaj yeem siv los pab cov neeg muab kev pabcuam tswj hwm kev sib txuas ntawm cov tuam txhab LANs thiab cov tuam txhab LANs thiab lwm cov tes hauj lwm.
Cov txheej txheem nkag mus rau fiber-optic Ethernethloov
Raws li pom nyob rau hauv daim duab, lub network tub ntxhais ntaus ntawv yog ib tug fiberhloovmuab tso rau hauv ib chav cell los yog chav tsev computer. Cov fiberhloovyog txuas nrog Internet ntugrouterlos yog sauhloovntawm tus nqi ntawm 1000 M / 100 M los ntawm fiber ntau optical los siv lub xov tooj ntawm tes nkag mus rau hauv Is Taws Nem.
Optical fiber ntauhloovyog txuas nrog lub optical network unit muab tso rau hauv tus neeg siv lub tsev los yog built-in optical fiber Ethernet card ntawm lub duplex 100M tus nqi los ntawm optical fiber thiab point-to-point hom. Kev sib txuas ntawm fiber ntau opticalhloovthiab chav tsev kho qhov muag los ntawm qhov kho qhov muag fiber ntau nkag mus rau Is Taws Nem yog ib hom fiber ntau ob txoj kev.
Piv nrog rau cov uas twb muaj lawm 5 - kab - raws li LAN broadband nkag, qhov kev nkag tau no muaj cov yam ntxwv tseem ceeb hauv qab no: Cov nqi qis FTTH daws; tshem tawm hauv pem tebhloov, tsuas yog lub cell chav tsev yog ib tug active node, txo nqi txij nkawm; Tus tibhloovnode nyob rau hauv lub cell chav yuav zoo txhim kho kev siv ntawmhloovchaw nres nkoj. Ultra siab bandwidth, yog 100 npaug ADSL; Ntev mus ntev; Network chaw taws teeb saib xyuas ntawm txhua qhov chaw nres nkoj photoelectric module.Nrog qhov chaw nres nkoj cais thiab chaw nres nkoj bandwidth tswj kev ua haujlwm; Lub zog Web Server network tswj kev ua haujlwm.Cov tswv yim no tshwj xeeb yog tsim nyog rau cov neeg siv nyob hauv ib puag ncig, cov tsev ua haujlwm, tsev kawm ntawv thiab tsev kho mob, nrog rau cov tswv lag luam hauv xov tooj thiab cov neeg nyob hauv network.
Cov ntsiab lus:
Nyob rau hauv kev pom ntawm txoj kev loj hlob zoo, daim ntawv thov ntawm optical fiber nyob rau hauv lub nkag network yuav tsum xub hloov lub feeder cable nrog feeder fiber, thiab ces txuas mus rau tus neeg siv. Txawm li cas los xij, tus nqi tau nce siab thiab siab dua, tam sim no, cov khoom siv kho qhov muag feem ntau tsuas yog ncav cuag lub thawv xa khoom ntawm txoj kev, uas yog qhov chaw nkag mus rau kev lag luam (SAP).
Lub hom phiaj kawg ntawm qhov ntshiab optical fiber nkag network yog los txhawb cov fiber ntau optical rau cov neeg siv nyob hauv. Tam sim no, nws tsis yog qhov tseeb los nqa cov khoom siv kho qhov muag hauv tsev, vim tias tus nqi ntawm cov khoom siv kho qhov muag tseem kim heev, yog li kev siv cov khoom siv fiber ntau Ethernet nkag mus yog cov nqi qis FTTH.
