I-Ethernet yitekhnoloji yenethiwekhi yendawo yekhompyuter, esetyenziswa ikakhulu ukudibanisa iinkqubo ezininzi zenethiwekhi ukufezekisa inethiwekhi yendawo yendawo (LAN). Kukho iintlobo ezininzi ze-Ethernet kwimarike, apho i-Ethernet ekhawulezayo kunye ne-Gigabit Ethernet zezona ziqhelekileyo. I-Ethernet ekhawulezayo (FS) iya kukunika uthelekiso oluneenkcukacha lwe-Ethernet ekhawulezayo kunye ne-Gigabit Ethernet ukwahlula umahluko phakathi kwezi zimbini.
Yintoni i-ethernet ekhawulezayo?
I-Ethernet ekhawulezayo (FE) ligama le-Ethernet kwinethiwekhi yekhompyuter, ebonelela ngezinga lokudluliselwa kwe-100Mbps. Umgangatho we-IEEE 802.3u 100BASE-T Fast Ethernet waziswa ngokusemthethweni yi-IEEE kwi-1995, kwaye izinga lokudluliselwa kwe-Ethernet ngokukhawuleza laliyi-10Mbps ngaphambili. Umgangatho we-Ethernet okhawulezayo uquka amacandelwana amathathu: 100BASE-FX, 100BASE-TX, kunye ne-100BASE-T4. I-100 ibonisa izinga losulelo lwe-100Mbit/s. "ISISEKO" sithetha usasazo lwebhendi; Ileta emva kodash ibhekisela kwisixhobo sokuhambisa esithwala umqondiso, "T" imele isibini esijijekileyo (ithusi), "F" imele i-fiber optical; Uphawu lokugqibela (unobumba "X", inombolo "4", njl.) libhekisela kwindlela yekhowudi yomgca esetyenzisiweyo. Itheyibhile ilandelayo ibonisa iintlobo eziqhelekileyo ze-Ethernet ezikhawulezayo.
Yintoni iGigabit Ethernet?
Xa kuthelekiswa ne-Ethernet ekhawulezayo, i-Gigabit Ethernet (GE) inokubonelela ngezinga lokudluliselwa kwe-1000Mbps kwinethiwekhi yekhompyutheni. Umgangatho we-Gigabit Ethernet (eyaziwa ngokuba yi-IEEE 802.3ab standard) yapapashwa ngokusemthethweni yi-IEEE ngo-1999, kwiminyaka embalwa kuphela emva kokufika komgangatho we-Fast Ethernet, kodwa ayizange isetyenziswe ngokubanzi kude kube malunga ne-2010. I-Gigabit Ethernet ithatha ifomathi yefreyimu. ye-IEEE 803.2 Ethernet kunye ne-CSMA / CD indlela yokulawula ukufikelela kwimidiya, enokusebenza kwi-half duplex kunye ne-duplex mode epheleleyo. I-Gigabit Ethernet ineentambo ezifanayo kunye nezixhobo kwi-Fast Ethernet, kodwa iyaguquguquka kwaye inoqoqosho. Ngophuhliso oluqhubekayo lwe-Gigabit Ethernet, iinguqulelo ezingaphezulu ziye zavela, ezifana ne-40G Ethernet kunye ne-100G Ethernet. I-Gigabit Ethernet inemigangatho eyahlukeneyo yomzimba, efana ne-1000BASE-X, i-1000BASE-T, kunye ne-1000BASE-CX.
Oku kungasentlai intshayelelo emfutshane yeGigabit Ethernet kunye ne-Ethernet ekhawulezayo eziswe kuwe nguShenzhenHDV Isixhobo sombaneon Technology LTD kunye ne-SShenzhenHDV Isixhobo sombaneon I-Technology LTD yinkampani ekhethekileyo kunxibelelwano lwe-optical njengesona sixhobo sokuvelisa, imveliso yenkampani:I-ONU uthotho, uthotho lweemodyuli zokukhanya,OLT series, transceiver series ezishushu iimveliso.
Ukuqaliswa kwe-OumbonoFiberFerrule
Uninzi lwemicu ye-optical esihlala siyibona i-optical fiber jumpers, oko kukuthi, zombini iziphelo zinezihlanganisi, ezinokuthi zifakwe ngokuthe ngqo kwaye zisuswe ngaphandle kokusebenzisa ezinye izixhobo, into ebizwa ngokuba yi-connector ibhekisela kwi-SC, FC, LC kunye nezinye iintlobo zokuhlelwa. .
Kwaye yintoni eyona nto ingundoqo, njengoko igama lithetha ukuba inokufakwa kwaye ikhutshwe kwisiseko, ngokuqhelekileyo yenziwe nge-ceramic, ingundoqo ngokubanzi ngexesha elifanayo kunye nekhonkco, okanye ukuthetha ngokubanzi, undoqo ulingana nekhonkco. , uthini umcimbi? Makhe ndikuxelele oku kancinci.
Undoqo ngaphakathi kwifiber engenanto eneneni ubhityile kakhulu kwaye kulula kakhulu ukuqhawuka, ngoko kukho into efuna ukuyikhusela. Ngombindi wefiber, siya kubeka i-cladding ukugubungela ingundoqo ukuze idlale indima yokukhusela, ngoko umsila wefiber sisebenzisa i-ceramic core. Kukho umngxuma omncinci kakhulu kumbindi wombindi, undoqo ugqojozwe kulo mngxuma kwindawo yentsimbi kwaye emva koko uphume kwindawo yeceramic, inxalenye eyongezelelweyo inqunyulwe kwicala le-ceramic, kwaye emva koko uthathe isixhobo sokugaya. inxalenye eyongezelelweyo ithe tyaba, kwaye ulumke xa usila, amandla amaninzi nawo aya kwaphula undoqo ngaphakathi kumbindi. (U-Xiabian ukhumbule ukuba i-core yangaphakathi yachithwa ngesandla ngexesha lovavanyo lweyunivesithi. Xa ukukhanya kuhanjiswa, kufunyenwe ukuba intloko yeplagi ikhupha ukukhanya okubomvu okucacileyo, kodwa amandla okuvavanya akaphezulu, kuba ukukhanya akusekho. isasazwe kumgca othe ngqo, kodwa ihlakazekile, okubangela ukukhanya okuphantsi kakhulu kulinganiswe ngamanani Ukuphela kwentsimbi kuphakathi kwe-fiber optical, ekhuselwe ngokubanzi ngokugquma kunye nokwaleka Intloko engundoqo kunye nenxalenye ephakathi kufuneka idityaniswe kunye, kungekhona kuphela uxhulumaniso oluluqilima, kodwa nokuthintela ukuphuphuma kokukhanya, Kakade ke, intsimbi engundoqo ayidityaniswanga kwi-fiber optical, ingasetyenziselwa imveliso ye-BOSA.
ShenzhenHDV Isixhobo sombaneon IteknolojiLTD. izisa inkcazo ye "optical fiber plug", kwaye inkampani yethu ngumenzi wezixhobo zonxibelelwano zobuchwephesha, ezona mveliso ziphambili zigubungela ngaphezulu. kunokubaI-ONU uthotho,OLT uchungechunge, uchungechunge lweemodyuli ezibonakalayo, uchungechunge lwe-transceiver njalo njalo. Ezi zixhobo zingentla zineenkcazo ezahlukeneyo kunye neemodeli zokubonelela ngeenkonzo ezijoliswe kuzo kwiimeko ezahlukeneyo zemfuno yenethiwekhi, wamkelekile ukufika kwakho.
