100M fiber ntau optic transceiver (ib lub teeb thiab 8 hluav taws xob) Plug thiab Ua Si Yooj Yim Siv

Kev nkag siab thiab qhov sib txawv ntawm kev sib cais ntawm kev sib cais thiab kev cais lub cev txog Ethernet fiber optic transceivers

Niaj hnub no, nrog rau kev siv dav dav ntawm Ethernet, hauv ntau thaj chaw, xws li hluav taws xob fais fab, kev lag luam, kev ruaj ntseg pej xeem, tub rog, kev tsheb ciav hlau, thiab kev sib koom tes ntawm cov tuam txhab loj thiab cov tsev kawm ntawv, muaj kev sib cais ntawm lub cev Ethernet, tab sis dab tsi yog kev cais lub cev. Ethernet?Yuav ua li cas txog lub net?Dab tsi yog logically cais Ethernet?Yuav ua li cas peb txiav txim siab kev cais tawm piv rau lub cev kev sib cais?
Kev cais tawm ntawm lub cev yog dab tsi:
Lub npe hu ua "kev cais lub cev" txhais tau hais tias tsis muaj kev sib koom ua ke ntawm cov ntaub ntawv sib txuas ntawm ob lossis ntau lub network, thiab tsis muaj kev sib cuag ntawm lub cev / cov ntaub ntawv txuas txheej / IP txheej.Lub hom phiaj ntawm kev sib cais ntawm lub cev yog los tiv thaiv cov cuab yeej kho vajtse thiab kev sib txuas lus ntawm txhua lub network los ntawm kev puas tsuaj ntuj tsim, kev tsim kev puas tsuaj rau tib neeg thiab kev tawm tsam ntawm cov xov hlau.Piv txwv li, kev cais lub cev ntawm lub network sab hauv thiab cov pej xeem network tuaj yeem ua kom ntseeg tau tias cov ntaub ntawv sab hauv network tsis tawm tsam los ntawm hackers los ntawm Is Taws Nem.

Dab tsi yog logical cais:
Lub logical isolator kuj yog ib qho kev sib cais ntawm cov tes hauj lwm sib txawv.Tseem muaj cov ntaub ntawv sib txuas ntawm lub cev txheej / cov ntaub ntawv txuas txheej ntawm qhov kev sib cais, tab sis cov txheej txheem kev siv tau los xyuas kom meej tias tsis muaj cov ntaub ntawv txuas ntawm qhov kev sib cais, uas yog, qhov tseeb.Kev rho tawm, qhov kev sib cais ntawm lub network optical transceivers / hloov pauv ntawm kev ua lag luam feem ntau ua tiav los ntawm kev faib VLAN (IEEE802.1Q) pawg;

VLAN yog sib npaug rau kev tshaj tawm xov xwm ntawm txheej thib ob (cov ntaub ntawv txuas txheej) ntawm OSI cov qauv siv, uas tuaj yeem tswj cov cua daj cua dub hauv VLAN.Tom qab faib VLAN, vim qhov txo qis ntawm qhov tshaj tawm tshaj tawm, qhov kev sib cais ntawm ob qhov sib txawv VLAN pab pawg sib txuas network tau pom..

Hauv qab no yog ib daim duab schematic ntawm kev sib cais logical:

Daim duab saum toj no yog daim duab kos duab ntawm ib qho kev sib cais 1 optical 4 hluav taws xob fiber ntau optic transceiver: 4 Ethernet channels (100M lossis Gigabit) zoo ib yam li 4 kab ntawm txoj kev loj, nkag mus rau hauv qhov, qhov av yog ib txoj kab, thiab Qhov kev tawm tom qab ntawd muaj 4 txoj kab, 1 optical thiab 4 hluav taws xob 100M logic cais fiber ntau optic transceivers, qhov chaw nres nkoj optical kuj yog 100M, thiab bandwidth yog 100M, yog li cov ntaub ntawv network los ntawm 4 raws ntawm 100M yuav tsum tau teem caij rau ntawm 100M. fiber ntau channel.Thaum nkag thiab tawm, kab thiab tawm mus rau lawv txoj kab sib txuas;Yog li ntawd, nyob rau hauv cov kev daws teeb meem no, cov ntaub ntawv network yog sib xyaw hauv Fiber Channel thiab tsis raug cais tawm txhua;
