SFP (Foom yar oo ku xidhan) waa nooc la cusboonaysiiyay oo GBIC ah (Giga Bitrate Interface Converter), magaceeduna waxa uu ka dhigan yahay muuqaalkiisa is haysta oo la xidhi karo. Marka la barbar dhigo GBIC, cabbirka moduleka SFP si weyn ayaa loo dhimay, qiyaastii kala bar GBIC. Cabbirkan is haysta waxay ka dhigan tahay in SFP lagu habayn karo in ka badan labanlaab tirada dekedood ee isla gole, taas oo si weyn u kordhinaysa cufnaanta dekeda. Inkasta oo cabbirka la dhimay, hawlaha moduleka SFP asal ahaan waa isku mid sida GBIC oo dabooli kara baahiyo kala duwan oo shabakadeed. Si loo fududeeyo xusuusta, qaar ka mid ah soosaarayaasha beddelka ayaa sidoo kale ugu yeera modules-yada SFP "miniature GBIC" ama "MINI-GBIC".

Maaddaama baahida loo qabo fiber-ilaa-guriga (FTTH) ay sii socoto inay koraan, baahida loo qabo transceivers-ka ishaarada indhaha ee la yareeyay (Transceivers) ayaa sidoo kale sii xoogeysaneysa. Naqshadeynta moduleka SFP ayaa tan tixgelin buuxda siinaysa. Isku dhafka ay la leedahay PCB uma baahna biin alxanka, taasoo ka dhigaysa mid ku habboon in lagu isticmaalo kombuyutarka. Taas bedelkeeda, GBIC wax yar ayay ka weyn tahay cabbirkeeda. Inkasta oo ay sidoo kale la xiriirto guddiga wareegga oo aan u baahnayn alxan, cufnaanta dekeddu uma fiicna sida SFP.
Sida qalab is-dhexgal ah oo u beddela calaamadaha korantada gigabit ee calaamadaha indhaha, GBIC waxay qabataa naqshad kuleyl ah oo la isku beddeli karo waana heer caalami ah oo si heersare ah loo beddeli karo. Isdhaafsigeeda awgeed, dawiyayaasha gigabit ee loogu talagalay interface GBIC ayaa haysta qayb weyn oo ka mid ah suuqa. Si kastaba ha ahaatee, qeexida fiilooyinka ee dekedda GBIC waxay u baahan yihiin fiiro gaar ah, gaar ahaan marka la isticmaalayo fiber multimode. Isticmaalka kaliya fiber multimode waxay keeni kartaa buuxinta gudbiyaha iyo qaataha, taasoo kordhinaysa heerka qaladka yara. Intaa waxaa dheer, marka la isticmaalayo 62.5 micron multimode fiber, xadhig balastar hab hagaajinta waa in lagu rakibaa inta u dhaxaysa GBIC iyo fiber multimode si loo hubiyo in isku xidhka u fog fogaanta iyo waxqabadka. Tani waa in loo hoggaansamo heerarka IEEE, iyadoo la hubinayo in laydhka laysarka laga soo saaro meel sax ah oo ka baxsan xarunta si loo buuxiyo heerka IEEE 802.3z 1000BaseLX.
Isku soo wada duuboo, GBIC iyo SFP labaduba waa aalado is-dhexgal ah oo u beddela calaamadaha korantada ee calaamadaha indhaha, laakiin SFP aad ayay u cufan xagga nashqadaynta waxayna ku habboon tahay xaaladaha u baahan cufnaanta dekedda sare. GBIC, dhanka kale, waxay ku jirtaa meel suuqa ka mid ah sababtoo ah isbeddelka iyo xasilloonida. Markaad dooranayso, waa inaad go'aansataa nooca moduleka aad isticmaalayso iyadoo lagu salaynayo baahiyaha iyo xaaladaha dhabta ah.
