I-SFP (I-PLUGGABLE YEFOMU ELINCANE) iwuhlobo oluthuthukisiwe lwe-GBIC (Giga Bitrate Interface Converter), futhi igama layo limelela isici sayo esihlangene nesixhunywayo. Uma kuqhathaniswa ne-GBIC, usayizi wemojula ye-SFP inciphe kakhulu, cishe uhhafu we-GBIC. Lo sayizi ohlangene usho ukuthi i-SFP ingacushwa ngenani lamachweba angaphezu kokuphindwe kabili kuphaneli efanayo, okwandisa kakhulu ukuminyana kwembobo. Nakuba ubukhulu buncishisiwe, imisebenzi ye-module ye-SFP ngokuyisisekelo iyafana ne-GBIC futhi ingahlangabezana nezidingo ezihlukahlukene zenethiwekhi. Ukwenza kube lula inkumbulo, abanye abakhiqizi bokushintsha baphinde babize amamojula e-SFP ngokuthi "i-GBIC encane" noma "MINI-GBIC".

Njengoba isidingo se-fiber-to-the-home (FTTH) siqhubeka sikhula, isidingo sama-transceivers optical optical miniaturized (Transceivers) siya ngokuya siba namandla. Ukuklanywa kwemojula ye-SFP kucabangela lokhu ngokugcwele. Ukuhlanganiswa kwayo ne-PCB akudingi i-pin soldering, okwenza kube lula ukuyisebenzisa ku-PC. Ngokuphambene, i-GBIC ikhudlwana ngosayizi. Yize iphinde ixhumene nebhodi lesekethe futhi ayidingi i-soldering, ukuminyana kwayo kwechweba akukuhle njenge-SFP.
Njengesisetshenziswa esibonakalayo esiguqula amasiginali kagesi we-gigabit abe amasiginali okubona, i-GBIC yamukela umklamo oshintshwayo oshisayo futhi iyindinganiso eshintshashintshayo kakhulu futhi yamazwe ngamazwe. Ngenxa yokushintshana kwayo, amaswishi egigabit aklanywe ngesixhumi esibonakalayo se-GBIC athatha ingxenye enkulu yemakethe. Kodwa-ke, ukucaciswa kwekhebula kwembobo ye-GBIC kudinga ukunakwa, ikakhulukazi uma usebenzisa i-multimode fiber. Ukusebenzisa i-multimode fiber kuphela kungase kubangele ukugcwala kwesidlulisi kanye nomamukeli, ngaleyo ndlela kukhuphule izinga lephutha elincane. Ngaphezu kwalokho, uma usebenzisa i-62.5 micron multimode fiber, intambo yesichibi sokulungiswa kwemodi kufanele ifakwe phakathi kwe-GBIC ne-multimode fiber ukuze kuqinisekiswe ibanga elilungile lesixhumanisi nokusebenza. Lokhu okokuthobela izindinganiso ze-IEEE, kuqinisekiswe ukuthi i-laser beam ikhishwa endaweni enembile engekho maphakathi ukuze ihlangabezane nezinga le-IEEE 802.3z 1000BaseLX.
Kafushane, kokubili i-GBIC ne-SFP kungamadivayisi esixhumi esibonakalayo aguqula amasignali kagesi abe amasignali okubona, kodwa i-SFP ihlangene kakhulu ekwakhiweni futhi ifanele izimo ezidinga ukuminyana kwembobo okuphezulu. I-GBIC, ngakolunye uhlangothi, ithatha indawo emakethe ngenxa yokushintshana kwayo nokuzinza. Lapho ukhetha, kufanele unqume ukuthi yiluphi uhlobo lwemojuli ozoyisebenzisa ngokusekelwe ezidingweni zangempela kanye nezimo.
