I-SFP (I-PLGGABLE YEFOMU ENCINCI) yinguqulo ephuculweyo ye-GBIC (i-Giga Bitrate Interface Converter), kwaye igama layo limele i-compact kunye ne-pluggable feature. Xa kuthelekiswa ne-GBIC, ubungakanani bemodyuli ye-SFP buncitshiswe kakhulu, malunga nesiqingatha se-GBIC. Lo bungakanani obuhlangeneyo buthetha ukuba i-SFP inokuqwalasela ngokuphindwe kabini inani lezibuko kwiqela elinye lolawulo, ukwandisa kakhulu uxinano lwezibuko. Nangona ubungakanani buncitshisiwe, imisebenzi yemodyuli ye-SFP ngokusisiseko iyafana ne-GBIC kwaye inokuhlangabezana neemfuno ezahlukeneyo zenethiwekhi. Ukuququzelela imemori, abanye abavelisi bokutshintsha kwakhona babiza iimodyuli ze-SFP "i-GBIC encinci" okanye "i-MINI-GBIC".
1.25Gbps 1550nm 80 Duplex SFP LC DDM Imodyuli
Njengoko imfuno ye-fiber-to-the-home (FTTH) iqhubeka ikhula, imfuno ye-miniaturized optical signal transceivers (Transceivers) nayo iya ikhula ngamandla. Uyilo lwemodyuli ye-SFP luthatha oku kuqwalaselo olupheleleyo. Indibaniselwano yayo kunye nePCB ayifuni i-pin soldering, iyenza ibe lula ukuyisebenzisa kwiPC. Ngokwahlukileyo, i-GBIC inkulu kancinci ngobukhulu. Nangona iphinde idibane nebhodi yesekethe kwaye ayifuni i-soldering, ubuninzi bayo bezibuko abulungile njenge-SFP.
Njengesixhobo sonxibelelwano esiguqula imiqondiso yombane yegigabhithi ibe ziimpawu zamehlo, i-GBIC ithatha uyilo oluguquguqukayo olushushu kwaye inokutshintshwa kakhulu kunye nomgangatho wamazwe ngamazwe. Ngenxa yokutshintshiselana kwayo, iiswitshi zegigabit eziyilwe nge-GBIC interface zithatha isabelo esikhulu semarike. Nangona kunjalo, iinkcukacha ze-cabling ze-GBIC port zifuna ukuhoywa, ngakumbi xa usebenzisa i-multimode fiber. Ukusebenzisa kuphela i-multimode fiber kunokubangela ukugcwala kwe-transmitter kunye ne-receiver, ngokwandisa izinga lempazamo encinci. Ukongezelela, xa usebenzisa i-62.5 micron i-multimode fiber, i-mode adjustment patch cord kufuneka ifakwe phakathi kwe-GBIC kunye ne-multimode fiber ukuqinisekisa umgama ofanelekileyo wekhonkco kunye nokusebenza. Oku kukuthobela imigangatho ye-IEEE, ukuqinisekisa ukuba i-laser beam ikhutshiwe kwindawo echanekileyo engekho-ziko ukuhlangabezana nomgangatho we-IEEE 802.3z 1000BaseLX.
Isishwankathelo, zombini i-GBIC kunye ne-SFP zixhobo zokudibanisa eziguqula izibonakaliso zombane zibe yimiqondiso ye-optical, kodwa i-SFP idibene ngakumbi kuyilo kwaye ifanelekile kwiimeko ezifuna ubuninzi be-port. I-GBIC, kwelinye icala, ithatha indawo kwimarike ngenxa yokutshintshiselana kunye nokuzinza. Xa ukhetha, kuya kufuneka uthathe isigqibo sokuba loluphi uhlobo lwemodyuli oza kuyisebenzisa ngokusekwe kwiimfuno zokwenyani kunye neemeko.
