Optical fiber transceiver yog qhov ua kom raug nqi thiab hloov kho tau yooj yim. Kev siv ntau tshaj plaws yog los hloov cov hluav taws xob cov hluav taws xob hauv kev sib hloov ntawm tus khub hloov mus ua lub cim hluav taws xob. Nws feem ntau siv hauv Ethernet tooj liab tooj liab uas tsis tuaj yeem npog thiab cov khoom siv hluav taws xob zoo yuav tsum siv los txuas qhov kev sib kis deb. Hauv qhov tseeb network ib puag ncig, nws tseem ua lub luag haujlwm tseem ceeb hauv kev txuas cov mais kawg ntawm qhov kho qhov muag mus rau cov nroog thaj tsam network thiab sab nraud network.
Lub pob nyem yog cov cuab yeej siv network los xa cov ntawv hluav taws xob (kho qhov muag). Nws yog lub luag haujlwm tseem ceeb hauv kev sib txuas lus sib txuas ntawm cov khoom siv sib txuas hauv lub xov tooj (xws li khoos phis tawj, tshuab luam ntawv, khoos phis tawj, thiab lwm yam). Nws feem ntau txuas nrog rau router kom koj tuaj yeem hla optical Cat nkag mus rau lub network.
Tus nqi sib kis
Tam sim no, fiber ntau kis ua ke yuav tau muab faib ua 100M fiber ntau kis tau tus kabmob, Gigabit fiber ntau chaw kis kab mob thiab 10G fiber ntau qhov chaw kis tau. Ntawm lawv, feem ntau muaj 100M thiab Gigabit fiber optic transceivers, uas muaj kev lag luam zoo thiab kev daws teeb meem hauv tsev thiab me thiab nruab nrab kev lag luam network. Lub keyboards txuas nrog 1G, 10G, 25G, 100G thiab 400G keyboards. Noj cov chaw loj cov ntaub ntawv chaw ua haujlwm piv txwv, 1G / 10G / 25G hloov khoom siv yog siv rau ntawm txheej nkag los yog hloov ToR, thaum 40G / 100G / 400G keyboards feem ntau siv raws li tus hloov pauv hloov lossis caj qaum.
Teeb meem nyuaj
Cov khoom siv hluav taws xob fiber ntau yog qhov yooj yim network kho vajtse cov khoom siv nrog tsawg dua cuam tshuam dua qhov hloov chaw, yog li lawv cov xov hlau thiab cov sib txuas tau yooj yim. Lawv tuaj yeem siv ib leeg los yog teeb tsa ntawm kev muag. Txij li cov optical fiber transceiver yog ntsaws-thiab-ua si, nws cov txheej txheem kev teeb tsa kuj yog yooj yim heev: tsuas yog ntxig rau cov xov tooj ntawm cov xov tooj hluav taws xob thiab optical fiber jumper mus rau qhov sib txuas hluav taws xob thiab kho qhov muag, thiab tom qab ntawd txuas lub tooj liab cable thiab optical fiber rau lub network ntaus ntawv Cov ob qho tib si xaus tau zoo.
Lub tshuab hloov network tuaj yeem siv ib leeg hauv tsev hauv tsev lossis chaw ua haujlwm me, lossis nws tuaj yeem ntsia tau rau ntawm cov khib nyiab hauv cov chaw loj cov ntaub ntawv network. Feem ntau, koj yuav tsum ntsaws tus qauv rau hauv qhov chaw nres nkoj coj, thiab tom qab ntawd siv lub network cable lossis cov kho qhov muag fiber ntau kom txuas mus rau lub khoos phis tawm lossis lwm cov cuab yeej network. Nyob rau hauv qhov chaw siab cabling, thaj ua rau thaj chaw, lub thawv hluav taws xob fiber ntau, thiab cov cuab yeej tswj kab hluav taws xob yuav tsum tau siv los tswj cov kab xev thiab ua kom yooj yim ntawm cov xov hlau. Txog kev tswj lub network hloov, qee qhov ua haujlwm siab yuav tsum muaj, xws li SNMP, VLAN, IGMP thiab lwm yam haujlwm.
Muaj nuj nqi configuration
Kev siv hluav taws xob-rau-kho qhov muag (kev siv hluav taws xob-rau-hluav taws xob) thiab cov kab hluav taws xob kho qhov muag hluav taws xob yog ob hom sib xws. Cov qub tuaj yeem hloov hluav taws xob cov cim rau hauv cov cim kho qhov muag kom paub qhov kev sib txuas ntawm cov khoom siv raws li tooj liab cabling kom ntev txuas qhov kev sib kis; thaum lub tom kawg tuaj yeem paub pom tseeb ib qho-hloov pauv hloov pauv, ib leeg dual fiber ntau hloov thiab yoj wavelength hloov pauv (feem ntau yog hloov ua ke nthwv ntawm 1310nm thiab 1550nm rau WDM wavelengths).
Piv nrog kho qhov muag transceiver, txoj haujlwm ntawm txoj kev hloov pauv yog qhov nyuaj dua, uas tau txiav txim siab los ntawm nws cov kev ua haujlwm hauv lub network. Raws li lub network txheej, lawv tuaj yeem faib ua txheej 2, txheej 3, thiab txheej txheej 4 hloov. Nquag, txheej txheej 2 yog cov hloov pauv pib siv los xa cov ntaub ntawv thiab ua qhov yuam kev tshuaj xyuas ntawm txhua tus ncej xa thiab txais. Txheej 3 thiab Txheej 4 cov khoom siv hloov mus ntxiv muaj cov kev hloov pauv uas tuaj yeem xa cov pob ntawv xa mus rau txoj hau kev tau zoo tshaj plaws. Tsis tas li ntawd xwb, lawv kuj muaj qee cov haujlwm tseem ceeb, xws li MLAG, STP, VXLAN, thiab lwm yam.
1. Cov khoom siv hluav taws xob fiber ntau siv thaum Ethernet cables tsis tuaj yeem npog thiab cov las hluav taws xob dhia yuav tsum siv cov khoom sib kis tau ntev li qhov peev nyiaj tsis tshua pom. Lawv tuaj yeem siv rau kev tsim kho cov cheeb tsam hauv nroog thiab cov nroog sib txuas hauv nroog, xws li cov tuam txhab kev lag luam thiab cov xaib rov qab lub nroog.
2. Lub network hloov pauv muaj ntau lub ports rau cov khoom sib txawv (xws li khoos phis tawj thiab tshuab luam ntawv) los sib txuas lus hauv LAN. Hauv lwm lo lus, lub network hloov yog ib qho khoom siv hloov tau ntxiv, uas tuaj yeem muab tso rau hauv kev sib txuas sib txuas kom tau nthuav dav hauv network. Ib qho ntxiv, nws tuaj yeem tiv thaiv kev thauj mus los ntawm ob lub khoom siv los ntawm kev cuam tshuam koj lwm cov khoom siv hauv tib lub network, tso cai rau koj los tswj lub network tau yooj yim.
3. Cov kab hluav taws xob fiber ntau thiab cov hloov xaib kuj tseem tuaj yeem ua haujlwm hauv tib lub network. Piv txwv li, thaum lub network hloov tsuas muaj cov chaw nres nkoj hluav taws xob, tab sis yuav tsum xa tawm ntau dua 100 metres, nws yog qhov yuav tsum tau siv cov hluav taws xob xa hluav taws xob xa cov hluav taws xob xa mus rau cov cim hluav taws xob kom ua tiav kev sib kis tau.
Lub luag haujlwm ntawm fiber ntau qhov txuas thiab cov chaw hloov pauv sib txawv, tab sis lawv tuaj yeem ua haujlwm ua ke hauv Ethernet network. Ib qho uas yuav tsum nco ntsoov yog tias fiber ntau lub tshuab xa hluav taws xob tsuas yog siv rau kev hloov pauv tooj liab-rau-fiber kom txuas ntxiv qhov sib kis tau, thaum lub network txuas tau siv los txuas cov khoom siv sib txuas ua ke rau cov ntaub ntawv sib faib thiab sib txuas lus.
