Okokuqala, izixhobo zePCM kunye nezixhobo zePDH zizixhobo ezahlukeneyo ngokupheleleyo. I-PCM iyisixhobo esihlanganisiweyo sokufikelela kwinkonzo, kwaye izixhobo zePDH zizixhobo zothumelo lokukhanya. Isiginali yedijithali iveliswa ngesampulu, ubungakanani kunye nekhowudi ye-continuousl...

Umncedisi we-serial port ubonelela ngomsebenzi we-serial port ukuya kwi-Intanethi, enokuguqula i-RS-232/485/422 i-serial port ibe yi-TCP/IP network interface, kwaye igcine ukuhanjiswa kweendlela ezimbini ekuhleni kwedatha yamanani phakathi kwe-RS-232. /485/422 uthotho p...

Iiswitshi zemizi-mveliso zisebenza ngokukhethekileyo ekuyileni izisombululo zokuhlangabezana neemfuno zezicelo zemveliso eguquguqukayo nezahlukeneyo, kwaye zibonise isisombululo sonxibelelwano sonxibelelwano ngentambo yamandla engabizi kakhulu. Iiswitshi zemizi-mveliso nazo zohlulwe zibe t...

Kwinkalo yothungelwano lothungelwano, sihlala sisebenzisa ii-fiber optic transceivers kunye ne-protocol converters, kodwa abahlobo abangazi nto ingako ngazo banokubhidanisa ezi zimbini. Ke, yintoni umahluko phakathi kwe-fiber optic transceivers kunye nabaguquleli beprotocol? Ingqungquthela...

Abanye abathengi babuze, kukho utshintsho lwe-POE kwimarike abathi bayakwazi ukuhambisa i-150 yeemitha okanye iimitha ezingama-250, ngaba yinyani okanye bubuxoki? Okokuqala, kufuneka siqonde ukuba yintoni i-POE. I-POE sisishunqulelo se-Power over Ethernet, okuthetha ukuba ...

I-PDH i-transceiver optical (Plesiochronous Digital Hierarchy), inkqubo ye-quasi-synchronous transmission series system. I-PDH ii-transceivers optical transceivers ezinomthamo omncinci. I-PDH i-transceivers optical isetyenziswa ngokubanzi ngababini, ebizwa ngokuba yi-point-to-poi...

I-transceiver ye-Optical sisixhobo se-terminal sosasazo lwe-optical signal. I-transceivers optical kufuneka ihlelwe kwii-transceivers optical phone, i-video optical transceivers, i-audio optical transceivers, i-data optical transceivers, i-Ethernet optical tr...

Ngaba i-transceiver ebonakalayo yefowuni kulula ukuyisebenzisa? Ngokuqinisekileyo kulula ukuyisebenzisa, ngaphandle koko ayiyi kuba yimveliso yophuhliso lwembali yezixhobo zonxibelelwano! I-Telephone optical transceiver sisixhobo esiguqula imiqondiso yefowuni yemveli kwi...

Iindidi zojongano lwefowuni ezisetyenziswa ngokuqhelekileyo ze-transceivers optical phone zezi: i-loop relay interface (FXO), i-analog subscriber line interface (FXS), i-hotline phone interface (ifowuni esemthethweni), i-interface ye-magnetic phone. Iitransceiver zefowuni zamehlo...

I-8-port POE network switch "Ungaze utshise isixhobo" iswitsha ye-POE ehlakaniphile, i-algorithm yokuziva ephucukileyo inamandla kuphela izixhobo ze-terminal IEEE 802.3af, ngoko akukho mfuneko yakukhathazeka malunga nokonakalisa umgangatho wabucala we-PoE okanye izixhobo ezingezizo ze-PoE. Inkqubo yonikezelo lwamandla ekrelekrele...
