I-transceiver ye-Optical sisixhobo se-terminal sosasazo lwe-optical signal. 1. Uhlobo lwe-transceiver ye-Optical: I-transceiver ye-Optical sisixhobo esiguqula i-E1 ezininzi (umgangatho wokuhanjiswa kwedatha kwimigca ye-trunk, ngokuqhelekileyo kwizinga le-2.048Mbps, lo mgangatho i...

Kwii-transceivers ze-fiber optical, umsebenzi oyintloko we-transceiver kukwandisa umgama wokuhanjiswa kwenethiwekhi, enokunciphisa isiphene ukuba intambo yenethiwekhi ayikwazi ukuhambisa umgama omde ukuya kwinqanaba elithile, kwaye izise lula kwikhilo yokugqibela ...

Ngokubanzi, intambo yokukhanya esebenzayo (AOC) kunye nentambo yokudibanisa ngokuthe ngqo (DAC) inomahluko ulandelayo: ① Ukusetyenziswa kwamandla okwahlukileyo: ukusetyenziswa kwamandla e-AOC kuphezulu kunokweDAC; ②Imigama eyohlukeneyo yothumelo: Ngokwethiyori, eyona mide...

Xa sihambisa imigama emide, siqhele ukusebenzisa iifiber zamehlo ukuhambisa. Ngenxa yokuba umgama wothumelo lwefiber optical mde kakhulu, ngokubanzi, umgama wothumelo lwefiber yemowudi enye ungaphezulu kweekhilomitha ezingama-20, kunye ne-distan yokudlulisela...

I-fiber media converter sisixhobo esiyimfuneko semveliso yenkqubo yonxibelelwano lwe-optical. Umsebenzi wayo oyintloko yiyunithi yokuguqula imidiya yokuhanjiswa kwe-Ethernet etshintshiselana umgama omfutshane weempawu zombane ezijijekileyo kunye neempawu zombane ezinde ...

Inqanaba lokukhusela lokutshintsha kwezoshishino liyilwe yi-IEC (i-International Electrotechnical Association). Imelwe yi-IP, kwaye i-IP ibhekisela "kukhuseleko lokungena. Ngoko ke, xa sithenga ukutshintshwa kwamashishini, yintoni inqanaba le-IP elifanelekileyo le-industrial switch ...

1. Ukuthembeka okuhlukeneyo: Ukutshintsha kwe-POE kukutshintsha okuxhasa ukunikezelwa kwamandla kwiintambo zenethiwekhi. Xa kuthelekiswa nokutshintsha okuqhelekileyo, iitheminali zokufumana amandla (ezifana nee-APs, iikhamera zedijithali, njl.njl.) akufuneki zenze iintambo zombane, kwaye zithembeke ngakumbi kwi ...

Zeziphi izilumkiso zokutshintsha kwamashishini kusetyenziso lwemihla ngemihla? (1) Musa ukubeka isixhobo kwindawo ekufutshane namanzi okanye efumileyo; (2) Musa ukubeka nantoni na kwintambo yombane, yigcine ingafikeleleki; (3) Ukuze uphephe umlilo, musa ukuqhina okanye uyisongele intambo; (4) Ip...

I-Industrial Fiber switch (Industrial Switch), eyaziwa ngokuba yi-industrial switch ye-Ethernet, ngumsebenzi kumaleko wesibini we-OSI (idatha yedatha yekhonkco yolwazi, echazwe ngokubhekisele "kwinethiwekhi yendawo yendawo"), ngokutsho kwe-MAC (ulawulo lwezitshixo zomnatha womnatha). ) ...

Iiswitshi ze-POE zibonelela wonke umntu ngokulula okukhulu kunye nesantya, kodwa ngenxa yemisebenzi epheleleyo yokutshintsha kwe-POE, nako akwanelanga. Ukuthembeka kokutshintsha kwe-POE kukwayeyona nto icacileyo kule ntsilelo. Ukuze utshintshe ngcono iPOE ca...
