Yintoni i-GBIC?
I-GBIC sisishunqulelo se-Giga Bitrate Interface Converter, esisisixhobo sojongano lokuguqula imiqondiso yombane yegigabit ibe ziimpawu zombane.I-GBIC inokuthi yenzelwe ukutshintshiselana okushushu.I-GBIC iyimveliso etshintshayo ehlangabezana nemigangatho yamazwe ngamazwe.Ukutshintsha kweGigabit okuyilwe nge-GBIC interface kuhlala isabelo esikhulu semarike kwimarike ngenxa yokuguquguquka kokutshintshana.
Yintoni i-SFP?
I-SFP sisishunqulelo se-SMALL FORM PLUGGABLE, enokuqondwa ngokulula njengoguqulelo oluphuculweyo lweemodyuli ze-GBIC.SFP zisiqingatha sobungakanani beemodyuli ze-GBIC kwaye zinokuqwalaselwe ngaphezu kwenani eliphindwe kabini lezibuko kwiqela elinye.Eminye imisebenzi. yemodyuli ye-SFP ngokusisiseko iyafana ne-GBIC.Abanye abavelisi bokutshintsha babiza imodyuli ye-SFP i-GBIC miniaturized (MINI-GBIC) .Iimodyuli zexesha elizayo kufuneka zixhase iplagi eshushu, oku kuthetha ukuba banokudibaniswa okanye banqanyulwe kwizixhobo ngaphandle kokuqhawula. amandla.Ngenxa yokuba imodyuli ye-optical i-hot-plugged, abaphathi benethiwekhi banokuphucula kunye nokwandisa inkqubo ngaphandle kokuvala inethiwekhi, kunye nefuthe elincinci kubasebenzisi be-intanethi.I-Hotplug iphinda ibenze lula ukugcinwa ngokubanzi kwaye ivumela abasebenzisi bokugqibela ukuba balawule kakuhle iimodyuli zabo ze-transceiver.K ngexesha elifanayo, ngenxa yale ntsebenzo yotshintshiselwano lobushushu, imodyuli yenza ukuba abaphathi bothungelwano bacwangcise iindleko zothumelo kunye neendleko zothumelo, imigama yekhonkco, kunye nazo zonke ii-topology zenethiwekhi.ngokweemfuno zophuculo lwenethiwekhi, ngaphandle kokutshintsha zonke iibhodi zenkqubo.Iimodyuli ze-optical ezixhasa le plugging eshushu ngoku zine-GBIC kunye ne-SFP, kuba ubukhulu be-SFP kunye ne-SFF bufana ngokufanayo, bunokufakwa ngokuthe ngqo kwi. ibhodi yesekethe, egcina indawo kunye nexesha lokupakisha, kwaye inoluhlu olubanzi lwezicelo.Ngoko ke, uphuhliso lwayo lwexesha elizayo lufanelekile ukulindela kwaye lunokusongela imarike ye-SFF.
Yintoni i-SFF?
I-SFF (iFomu encinci yeFactor) imodyuli ye-compact optical ithatha iteknoloji ye-optical echanekileyo kunye ne-circuit integration technology kunye nesiqingatha sobukhulu besiqhelo se-duplex SC (1X9) imodyuli ye-fiber optic transceiver. ukwandisa ingxinano yezibuko lomgca kunye nokunciphisa iindleko zenkqubo kwizibuko ngalinye.Ukwaleka, imodyuli encinci yempahla ye SFF yamkela ujongano lwe kt-rj olufana nomsebenzi womnatha wocingo lobhedu, ubungakanani obufanayo nojongano oluqhelekileyo lwecingo lobhedu kuthungelwano lwekhompyutha, olunceda inguqu yesixhobo sothungelwano esikhoyo esisekwe kwintambo yobhedu ukuya kwinqanaba eliphezulu lomnatha wefiber optical network ukuhlangabezana nokukhula okukhawulezayo kwemfuno ye-network bandwidth.
Uhlobo lwesixhobo soqhagamshelwano lwenethiwekhi
Ujongano lwe-BNC
Ujongano lwe-BNC lubhekisa kujongano lwentambo ye-coaxial.I-interface ye-BNC isetyenziselwa i-75 ye-euro coaxial uxhumano lwekhebula, ukubonelela ngeendlela ezimbini zokufumana (i-RX) kunye nokuthumela (TX), kwaye isetyenziselwa ukudibaniswa kwezibonakaliso ezingenakulinganisela.
I-Optical fiber interface
I-Fiber optic interface yi-interface ebonakalayo esetyenziselwa ukudibanisa i-fiber optic cables.Kukho ngokuqhelekileyo i-SC, i-ST, i-LC, i-FC kunye nezinye iindidi.Kudibaniso lwe-10base-f, ikhonkco ngokuqhelekileyo luhlobo lwe-ST, kunye nesinye isiphelo se-FC. iqhagamshelwe kwi-fiber optic cable rack.FC sisishunqulelo se-FerruleConnector.Ukuqiniswa kwayo kwangaphandle ngumkhono wensimbi kunye ne-fastening is screw buckle.ST interface idla ngokusetyenziselwa i-interface ye-10base-f.SC idla ngokusetyenziselwa i-100base-fx kunye ne-GBIC.LC ngokuqhelekileyo isetyenziselwa i-SFP.
RJ - 45 ujongano
I-interface ye-rj-45 yi-interface ye-Ethernet esetyenziswa ngokuqhelekileyo.I-Rj-45 ligama eliqhelekileyo leejekhi zemodyuli okanye iiplagi ezinezithuba ze-8 (izikhonkwane ezi-8) njengoko kuchazwe ngumgangatho wokudibanisa wamazwe ngamazwe, osemgangathweni yi-IEC (60) 603-7.
I-RS - 232 interface
I-interface ye-Rs-232-c (ekwaziwa ngokuba yi-EIA rs-232-c) yeyona ndlela ixhaphakileyo yonxibelelwano lwe-serial interface.Yaphuhliswa ngo-1970 ngumbutho woshishino lwe-elektroniki waseMelika (EIA) ngentsebenziswano neenkqubo zentsimbi, abavelisi bemodem kunye nekhompyutha. abavelisi be-terminal bemigangatho yonxibelelwano olulandelelanayo.Igama layo elipheleleyo "umgangatho wobugcisa we-serial binary data exchange interface phakathi kwezixhobo ze-terminal data (DTE) kunye nezixhobo zonxibelelwano lwedatha (DCE)". umxholo wesignali wepini nganye yekhonkco kunye nenqanaba leempawu ezahlukeneyo.
RJ - 11 ujongano
I-interface ye-RJ-11 yinto esiyibiza ngokuba yi-interface yomgca wefowuni.I-RJ-11 ligama eliqhelekileyo lomdibaniso ophuhliswe nguMbane waseNtshona.Imilo yayo ichazwa njenge-6-pin.Imilo yayo ichazwa njenge-6-pin connector .Eyayisaziwa njenge-WExW, i-x apha imele "i-active", uqhagamshelwano okanye inaliti inaliti.Umzekelo, i-WE6W inabo bonke abafowunelwa abathandathu, iNombolo 1 ukuya ku-6, i-interface ye-WE4W kuphela ISEBENZA izikhonkwane ezi-4, abafowunelwa ababini abangaphandle (1 kunye ne-6) sukusebenzisa, WE2W USEBENZISA kuphela izikhonkwane ezimbini ezisembindini (oko kukuthi, ujongano lwelayini yefowuni).
I-CWDM kunye ne-DWDM
Ngokukhula ngokukhawuleza kwenkonzo yedatha ye-Intanethi ye-Intanethi, imfuno ye-intanethi ye-intanethi ye-bandwidth iyanda.Nangona i-DWDM (i-dense wavelength division multiplexing) iteknoloji yeyona ndlela isebenzayo yokusombulula ukwandiswa kwe-bandwidth yomgca, i-CWDM (i-coarse wavelength division multiplexing) iteknoloji ineenzuzo ngaphezu I-DWDM kwiindleko zenkqubo, ukugcinwa kunye neminye imiba.
I-CWDM kunye ne-DWDM zombini i-wavelength division multiplexing technologies, enokudibanisa ukukhanya kwee-wavelengths ezahlukeneyo kwi-fiber engundoqo enye kwaye idlulisele kunye.ukungakwazi kunye nezinye iinkalo.
Umgangatho wamva nje we-ITU we-CWDM ngu-g.695, obonelela ngeeshaneli ze-18 ze-wavelength kunye nekhefu le-20nm ukusuka kwi-1271nm ukuya kwi-1611nm.Ukuqwalasela impembelelo yencopho yamanzi yesiqhelo g.I-fiber ye-652, iziteshi ze-16 zisetyenziswa ngokubanzi.Ngenxa yesithuba esikhulu sombhobho, i-separators yamaza edibeneyo kunye ne-lasers zincinci kunezixhobo ze-DWDM.
Izithuba zeshaneli ze-DWDM ziyi-0.4nm, i-0.8nm, i-1.6nm kunye nezinye iindidi ezahlukeneyo njengoko zifunwa, ezincinci kwaye zifuna izixhobo ezongezelelweyo zokulawula ubude be-wavelength.Ngoko ke, izixhobo ezisekelwe kwi-teknoloji ye-DWDM zibiza kakhulu kunezo zisekelwe kwi-teknoloji ye-CWDM.
I-PIN photodiode ngumaleko wezinto zohlobo lwe-n-doped lightly doped, eyaziwa ngokuba yi-I(Intrinsic) layer, phakathi kwe-doped p-type ephezulu kunye ne-n-type semiconductors.Ngenxa yokuba i-doped lightly, i-electron concentration iphantsi kakhulu.Emva kokusasazwa, i-depletion layer ebanzi kakhulu yenziwa, enokuphucula isantya sokuphendula kunye nokusebenza kakuhle kokuguqulwa.I-APD yi-photodiode enenzuzo.Xa uvakalelo lwe-optical receiver luphezulu, i-APD iyanceda ukwandisa umgama wothumelo lwenkqubo.
