1. Ukutshintsha kwamashishini kukwabizwa ngokuba yi-industrial Ethernet switches. Ngaphantsi kwemeko yangoku, kunye nophuhliso oluqhubekayo nolukhawulezayo kunye nokuqhubela phambili kweteknoloji yenethiwekhi, imfuno yothungelwano kwintsimi yezoshishino, ngakumbi kwintsimi ye-indus ...

I-transceiver ye-Optical sisixhobo esiguqula imiqondiso emininzi ye-E1 ibe yimiqondiso yokubona. I-Optical transceiver ikwabizwa ngokuba yi-optical transmission equipment. I-transceivers Optical inamaxabiso ahlukeneyo ngokwenani le-E1 (oko kukuthi, i-2M) izibuko ezithunyelwayo....

Ii-transceivers ze-Optical zingahlulwa zibe ziindidi ze-3 ngokweteknoloji: PDH, SPDH, SDH, HD-CVI. I-PDH i-transceiver optical: I-PDH (i-Plesiochronous Digital Hierarchy, i-quasi-synchronous digital series) i-transceiver ebonakalayo yinto encinci ye-optical transceiver...

I-router ngumaleko we-3 isixhobo sothungelwano. I-hub isebenza kumaleko wokuqala ( umaleko womzimba) kwaye akukho buchule bokucubungula obukrelekrele. Xa umjelo wezibuko elinye ugqithiselwa kwi-hub, ihambisa ngokulula yangoku kwamanye amazibuko, kwaye ayikhathali...

Ukufikelela kwiLayer Switch Ngokuqhelekileyo, inxalenye yenethiwekhi eqhagamshelwe ngokuthe ngqo kubasebenzisi okanye ifikelele kwinethiwekhi ibizwa ngokuba ngumaleko wokufikelela, kwaye inxalenye phakathi kwendawo yokufikelela kunye nomgangatho ongundoqo ubizwa ngokuba ngumaleko wokusabalalisa okanye i-convergence layer. Acc...

Ukutshintsha Umthamo Umthamo wokutshintsha kotshintshi, owaziwa ngokuba yi-backplane bandwidth okanye ukutshintshwa kwe-bandwidth, yimali eninzi yedatha enokuthi iphathwe phakathi kweprosesa ye-switch interface okanye ikhadi le-interface kunye nebhasi yedatha. Umnqwazi wotshintshiselwano...

Yintoni umahluko phakathi kweCa5e, iCat6, kunye neCat7? Udidi lwesihlanu (CAT5): I-frequency transmission yi-100MHz, esetyenziselwa ukuhanjiswa kwezwi kunye nokuhanjiswa kwedatha kunye nesantya esiphezulu sokudluliselwa kwe-100Mbps, esetyenziswa kakhulu kwi-100BASE-T kunye ne-10BASE-T inethiwekhi. Oku...

Imveliso yemodyuli ye-1 * 9 epakishweyo yaveliswa okokuqala ngo-1999. Yimveliso yemodyuli esisigxina. Ngokuqhelekileyo iphiliswa ngokuthe ngqo (i-soldered) kwibhodi yesekethe yesixhobo sonxibelelwano kwaye isetyenziswe njengemodyuli esisigxina ye-optical module. Ngamanye amaxesha ikwabizwa ngokuba...

1. Amanqanaba ahlukeneyo okusebenza: I-Layer 2 itshintshile isebenza kwi-data link layer, kwaye i-Layer 3 itshintshile isebenza kwi-network layer. Ukutshintsha kwe-Layer 3 akuphumeleli kuphela ukuhanjiswa kwepakethi yedatha ngesantya esiphezulu, kodwa kwakhona kufezekiseke ukusebenza kakuhle kwenethiwekhi ngokokwahluka...

Ii-transceivers zelizwe lethu zomnxeba ziphuhliswe ngokukhawuleza ngophuhliso lweshishini lokubeka iliso. Ukusuka kwi-analog ukuya kwidijithali, kwaye emva koko ukusuka kwidijithali ukuya kwi-high-definition, bahlala beqhubela phambili. Emva kweminyaka yokuqokelelwa kobugcisa, baye...
