SFP
SFP tuaj yeem nkag siab raws li kev hloov kho tshiab ntawm GBIC. Nws ntim tsuas yog 1/2 ntawm qhov ntawd ntawm GBIC module, uas tau nce qhov chaw nres nkoj ntom ntawm network li. Tsis tas li ntawd, SFP cov ntaub ntawv hloov cov nqi hloov tawm li ntawm 100Mbps rau 4Gbps.
SFP +
SFP + yog kev txhim kho version ntawm SFP uas txhawb nqa 8gbit / s fiber channel, 10g ethernet thiab Otu2, tus qauv kis rau tus neeg siv kho qhov muag. Ntxiv rau, SFP + kab ke ncaj qha (piv txwv li, sfp + chaw nres tsheb thiab cleso mirok nquag kho qhov muag ntawm ob qho chaw nyob ib sab-deb-nrug network hloov.
SFP28
SFP28 yog ib qho kev txhim kho tshiab ntawm SFP +, uas muaj qhov loj tib yam li SFP + tab sis tuaj yeem txhawb nqa ib leeg-channel kom ceev ntawm 25GB / s. SFP28 muab kev daws teeb meem zoo dua rau kev hloov kho 10G-25G-100g tes hauj lwm kom tau raws li qhov xav tau kev loj hlob ntawm cov ntaub ntawv txuas ntxiv tom ntej no.
QSFP +
QSFP + yog ib qho hloov tshiab ntawm QSFP. Tsis zoo li qsfp +, uas txhawb nqa 4 tus gbit / s channel / s, qsfp + txhawb nqa 4 x 10gbit / s channels ntawm tus nqi ntawm 40gbps. Piv nrog SFP +, tus nqi ntawm QSFP + yog plaub zaug siab dua li SFP +. QSFP + tuaj yeem siv ncaj qha thaum 40g network tau tso tseg, yog li txuag tus nqi thiab nce chaw nres nkoj ceev.
QSFP28
QSFP28 muab plaub qhov kev nrawm nrawm teeb liab. Tus nqi sib kis ntawm txhua channel sib txawv ntawm 25GBPs rau 40Gbps, uas tuaj yeem ua tau raws li cov kev xav tau ntawm 100 get eternet (4 x 25GBs) thiab EDR Infiniband cov ntawv thov. Muaj ntau hom QSFP28 cov khoom lag luam, thiab sib txawv ntawm 100 gbit siv, xws li 100 git / s conversion to ob 50 gb / s ceg txuas.
Qhov sib txawv thiab cov sib thooj ntawm SFP, SFP +, SFP28, QSFP +, QSFP28
Tom qab nkag siab dab tsi SFP, SFP +, SFP28, QSFP +, QSFP28 yog, qhov sib txawv ntawm ob yuav tau los qhia ntxiv.

SFP thiab SFP +: tib qhov loj me, cov nqi sib txawv thiab sib xws
Qhov loj me thiab tsos ntawm SFP thiab SFP + cov qauv yog tib yam, yog li cov cuab yeej tsim khoom siv ntawm SFP ntawm SFP + chaw nres nkoj. Vim yog tib qho loj me, ntau tus neeg siv khoom siv SFP Modules ntawm SFP + chaw nres nkoj ntawm cov pob taws. Qhov kev ua haujlwm no yog ua tau, tab sis tus nqi yog txo rau 1Gbit / s. Ib qho ntxiv, tsis txhob siv SFP + module hauv SFP qhov. Txwv tsis pub, qhov chaw nres nkoj lossis cov qauv hloov yuav raug puas ntsoog. Ntxiv nrog rau kev sib xyaw, SFP thiab SFP + muaj qhov sib kis sib txawv thiab cov qauv. SFP + tuaj yeem kis tau qhov siab tshaj plaws ntawm 4Gbit / s thiab ntau tshaj plaws ntawm 10Gbit / s. SFP yog ua raws SFF-8472 raws tu qauv thaum SFP + yog ua raws SFF-8431 thiab SFF-8432 kev cai.
SFP28 thiab SFP +: SFP28 Module hloov tuaj yeem txuas nrog SFP + chaw nres nkoj
Raws li tau hais los saum no, SFP28 yog qhov hloov kho tshiab ntawm SFP + nrog tib qho loj me tab sis cov nqi sib txawv. Tus nqi sib kis ntawm SFP + yog 10Gbit / s thiab hais tias ntawm SFP28 yog 25gbit / s. Yog hais tias SFP + Kho kho qhov muag tau muab tso rau SFP28 chaw nres nkoj, qhov txuas txuas kis tau yog 10Gbit / s, thiab lwm yam. Tsis tas li ntawd, SFP28 ncaj qha txuas tooj liab cable muaj ntau dua bandwidth thiab qis poob tshaj SFP + ncaj ncaj txuas tooj liab cable.
SFP28 thiab QSFP28: Cov qauv kev cai sib txawv
Txawm hais tias ob qho tib si SFP28 thiab QSFP28 nqa tus lej "", ob qho ob yam ob qhov ntau dua los ntawm cov qauv raws tu qauv. SFP28 txhawb nqa 25gbit / s nkaus xwb channel, thiab qsfp28 txhawb nqa plaub 25gbit / s channel. Ob qho tib si tuaj yeem siv rau ntawm 100g tes hauj lwm, tab sis nyob rau ntau txoj kev. QSFP28 tuaj yeem ua tiav 100 o kis tau los ntawm peb txoj kev tau hais los saud, tab sis SFP28 tso siab rau QSFP28 rau SFPP28 rau SFP28 rau SFP28 rau SFP28 Ceg-ceev cov cable ceev. Daim duab hauv qab no qhia txog kev sib txuas ncaj qha ntawm 100g QSFP28 txog 4 × SFP28 DAC.
QSFP thiab QSFP28: Cov nqi sib txawv, cov ntawv thov sib txawv
Tus qsfp + thiab qsfp28 modules yog ntawm tib qhov loj me thiab muaj plaub kis thiab tau txais cov channel. In addition, both QSFP+ and QSFP28 families have optical modules and DAC/AOC high-speed cables, but at different rates. Tus QSFP + Module txhawb nqa ib 40gbit / s tib-chan-channel tus nqi, thiab qsfp + dac / AOC txhawb A 4 x 10Gbit / S Transportion tus nqi. Lub QSFP28 module hloov cov ntaub ntawv ntawm tus nqi ntawm 100gbit / s. Lub QSFP28 DAC / AOC txhawb 4 x 25gbit / s lossis 2 x 50gbit / s. Nco ntsoov tias QSFP28 module tsis tuaj yeem siv rau 10G ceg sib txuas. Txawm li cas los xij, yog tias tus hloov pauv nrog QSFP28 Ports txhawb QSFP + Modules, koj tuaj yeem ntxig QSFP + Modules rau hauv QSFP28 Ports los siv 4 x 10G ceg txuas.
