Umgaqo osebenzayo: Emva kokuba nayiphi na i-node yokutshintsha ifumana umyalelo wokuhanjiswa kwedatha, ikhangela ngokukhawuleza itafile yedilesi egcinwe kwimemori ukuze iqinisekise indawo yokudibanisa yekhadi lenethiwekhi kunye nedilesi ye-MAC kwaye emva koko idlulisele idatha kwi-node.Ukuba indawo ehambelana nayo ifunyenwe kwitheyibhile yedilesi, ukuhanjiswa kuyenziwa;Ukuba akunjalo, umtshintshi uya kurekhoda idilesi ukuququzelela ukukhangela nokusetyenziswa okulandelayo.Ngokuqhelekileyo, utshintsho lufuna kuphela ukuthumela isakhelo kwindawo ehambelanayo, endaweni yokuyithumela kuzo zonke iindawo ezifana ne-hub, ngaloo ndlela igcina izixhobo kunye nexesha kunye nokuphucula izinga lokudluliselwa kwedatha.
Imowudi yothumelo: Ingaba idatha ihanjiswa njani kwiswitshi?Umgaqo olula kukudlulisa idatha ngokutshintshiselana ngolwazi, eyona ndlela yokudlulisa idatha yokutshintsha.Kwakudala, i-hub ayikwazanga ukufezekisa le mpembelelo.Isebenzise indlela yokwabelana yokuhanjiswa kwedatha.Yenza i-hub ingakwazi ukutshintsha i-hardware yomzimba ukuphucula izinga lonxibelelwano.Uhlobo losasazo ngolu hlobo lukwabizwa ngokuba “yi-shared network transmission kunxibelelwano.I-hub isetyenziswe njengesixhobo soqhagamshelwano kwaye inecala elinye kuphela lokuhamba kwedatha, ngoko ke ukusebenza kakuhle kokwabelana ngenethiwekhi kuphantsi kakhulu.Kule nkalo, umtshintshi unokusombulula le nxalenye yengxaki.Inokunxibelelana kwenye ikhompyuter, ingaphelelanga kwikhompyuter enye, kodwa inokunxibelelana kwiikhompyuter ezininzi ukuhambisa idatha.Ngethuba nje idilesi yendawo yekhadi lenethiwekhi yekhompyutheni idibaniswe kwitshintshi efanayo, oko kukuthi, idilesi ye-MAC, isetyenziselwa ukuchongwa kunye nememori.
Esikhundleni sokusasaza ukukhangela, inokufumana ngokuthe ngqo indawo ehambelanayo yedilesi ye-MAC kwaye igqibe unxibelelwano lokuhanjiswa kwedatha phakathi kweenodi ezimbini ngaphandle kokuphazamiseka kwangaphandle ngokusebenzisa ishaneli yothumelo lwedatha yesikhashana.Njengoko iswitshi nayo inemowudi yothumelo ephindwe kabini, inokuphinda iseke umjelo ozinikeleyo wethutyana phakathi kwezibini ezininzi zeenodi ukwenza ulwakhiwo lweshaneli yothumelo lwedatha-ntathu.
Esi sintshayelelo kuMgaqo wokuSebenza kunye neNdlela yoThutho lweDatha ngu-SShenzhen HDV Phoelectron Technology Co., Ltd. ithemba eli nqaku linokukunceda ukwandisa ulwazi lwakho.Ngaphandle kweli nqaku ukuba ujonge inkampani elungileyo yomenzi wezixhobo zonxibelelwano lwefiber onokuthi uyithathele ingqalelongathi.
Iimveliso zonxibelelwano eziveliswe yikhava yenkampani:
Imodyuli:iimodyuli zefiber optical, Iimodyuli ze-Ethernet, iimodyuli ze-fiber optical transceiver, iimodyuli zokufikelela kwifiber optical, Iimodyuli ze-SSFP ezibonakalayo, kwayeI-SFP optical fibers, njl.
Udidi lwe-ONU:EPON ONU, AC ONU, ifayibha optical ONU, CATV ONU, GPON ONU, XPON ONU, njl.
iklasi yeOLT:Ukutshintsha OLT, GPON OLT, EPON OLT, unxibelelwano OLT, njl.
Ezi mveliso zingentla zinokuxhasa iimeko ezahlukeneyo zenethiwekhi.Kwezi mveliso zonxibelelwano zingentla, inkampani yethu ineqela elinobuchule nelomeleleyo le-R&D ukunceda abathengi abanemiba yobuchwephesha kunye neqela elicinga ngakumbi kunye neqela leshishini elinobuchule ukunceda abathengi kwangoko.thethwanokunye nomsebenzi.
