SFP (MALL FORM PLUGGABLE) yog ib qho kev hloov kho tshiab ntawm GBIC (Giga Bitrate Interface Converter), thiab nws lub npe sawv cev rau nws qhov kev cog lus thiab pluggable feature. Piv nrog GBIC, qhov loj ntawm SFP module raug txo qis heev, txog ib nrab ntawm GBIC. Qhov loj me me no txhais tau tias SFP tuaj yeem teeb tsa nrog ntau dua ob npaug ntawm cov chaw nres nkoj ntawm tib lub vaj huam sib luag, ua kom qhov chaw nres nkoj ceev heev. Txawm hais tias qhov loj me me, qhov ua haujlwm ntawm SFP module yog qhov pib zoo ib yam li GBIC thiab tuaj yeem ua tau raws li ntau yam kev xav tau hauv network. Txhawm rau pab txhawb kev nco, qee lub tuam txhab hloov pauv kuj hu rau SFP modules "miniature GBIC" lossis "MINI-GBIC".

Raws li qhov kev thov rau fiber-to-the-tsev (FTTH) txuas ntxiv mus ntxiv, qhov kev thov rau cov teeb liab me me optical transceivers (Transceivers) kuj tseem muaj zog. Tus tsim ntawm SFP module siv qhov no rau hauv kev txiav txim siab tag nrho. Nws ua ke nrog PCB tsis xav tau tus pin soldering, ua rau nws yooj yim dua rau siv ntawm PC. Hauv qhov sib piv, GBIC yog qhov loj me me. Txawm hais tias nws tseem nyob rau sab kev sib cuag nrog lub rooj tsav xwm Circuit Court thiab tsis tas yuav tsum tau soldering, nws qhov chaw nres nkoj ceev tsis zoo li SFP.
Raws li cov khoom siv sib txuas uas hloov cov teeb liab gigabit hluav taws xob rau hauv cov teeb liab kho qhov muag, GBIC txais yuav tus qauv kub-swappable thiab yog qhov sib hloov tau thiab tus qauv thoob ntiaj teb. Vim nws interchangeability, gigabit keyboards tsim nrog GBIC interface tuav ib tug loj feem ntawm lub lag luam. Txawm li cas los xij, cov kab lus tshwj xeeb ntawm qhov chaw nres nkoj GBIC xav tau kev saib xyuas, tshwj xeeb tshaj yog thaum siv multimode fiber ntau. Siv tsuas yog multimode fiber ntau yuav ua rau saturation ntawm lub transmitter thiab receiver, yog li ua rau me ntsis yuam kev. Tsis tas li ntawd, thaum siv 62.5 micron multimode fiber ntau, hom kev hloov kho thaj qaum yuav tsum tau nruab nruab nrab ntawm GBIC thiab multimode fiber ntau kom ntseeg tau qhov kev sib txuas zoo thiab kev ua haujlwm. Qhov no yog ua raws li IEEE cov qauv, xyuas kom meej tias lub laser beam raug tso tawm los ntawm qhov tseeb qhov chaw tawm ntawm qhov chaw kom ua tau raws li IEEE 802.3z 1000BaseLX tus qauv.
Hauv cov ntsiab lus, ob qho tib si GBIC thiab SFP yog cov khoom siv sib cuam tshuam uas hloov hluav taws xob teeb liab rau hauv cov teeb liab kho qhov muag, tab sis SFP yog qhov sib cog lus ntau dua hauv kev tsim thiab tsim nyog rau cov xwm txheej uas xav tau qhov chaw nres nkoj ntau dua. GBIC, ntawm qhov tod tes, occupies ib qho chaw hauv kev ua lag luam vim nws interchangeability thiab stability. Thaum xaiv, koj yuav tsum txiav txim siab seb hom module siv raws li qhov xav tau tiag tiag thiab cov xwm txheej.
