Cov hom ntawm cov kho qhov muag xws li SFP, SFP +, SFP28, QSFP + thiab QSFP28 tsis txawv rau cov tub txawg. Cov qauv hluav taws xob kub no siv tau los txuas rau cov hloov network thiab lwm cov khoom siv hauv network (xws li cov servers lossis transceivers) rau kev sib kis cov ntaub ntawv.
Ua ntej qhia meej qhov sib txawv ntawm cov qauv no, peb yuav tsum paub dab tsi yog cov qauv ntawm SFP, SFP +, SFP28, QSFP thiab QSFP28. Peb yuav qhia cov qauv no ib ntu.
SFP
SFP tuaj yeem nkag siab txog li kev hloov kho dua tshiab ntawm GBIC. Nws lub ntim tsuas yog ib nrab ntawm GBIC module, uas zoo heev nce qhov chaw nres nkoj ntom ntawm cov khoom siv network. Ntxiv rau, cov ntaub ntawv sib kis ntawm SFPs nyob ntawm 100Mbps txog 4Gbps.
SFP +
SFP + yog kev txhim kho ntawm SFP, uas txhawb 8GBIT / s fiber ntau channel, 10G Ethernet thiab otu2. Ntxiv rau, qhov txuas ncaj qha cable (piv txwv li SFP + DAC high-speed cable thiab AOC active optical cable) tuaj yeem txuas ob SFP + cov chaw nres nkoj tsis ntxiv cov qauv kho qhov muag thiab cov txuas txuas (network cable lossis optical fiber jumper ), uas yog qhov kev xaiv zoo rau kev sib txuas ncaj qha ntawm ob kab hluav taws xob sib txuas nrug luv luv network.
SFP28
SFP28 yog kev kho kom zoo dua qub ntawm SFP +, uas muaj qhov loj tib yam li SFP +, tab sis tuaj yeem txhawb nqa ib qho channel 25Gb / s tus nqi. SFP28 muab cov kev daws teeb meem zoo rau kev kho dua 10G-25G-100G network, tuaj yeem ua kom tau raws li kev loj hlob txuas ntxiv ntawm cov txuas ntxiv mus ntawm cov ntaub ntawv chaw network.
QSFP +
QSFP + yog qhov hloov tshiab ntawm QSFP. QSFP tuaj yeem txhawb nqa plaub tshooj raws tib lub sijhawm, thiab cov ntaub ntawv ntawm txhua tus channel yog 1GBIT / s, tab sis QSFP + txawv ntawm QSFP. Nws txhawb 4 × 10Gbit / s channel kis, thiab tuaj yeem paub 40Gbps kis tus nqi los ntawm plaub kis. Piv nrog SFP +, qhov sib kis ntawm QSFP + optical module tuaj yeem ncav cuag plaub zaug ntawm SFP + optical module. Thaum xa tawm 40G network, QSFP + optical module tuaj yeem siv ncaj qha, uas tuaj yeem txuag nqi thiab txhim kho qhov chaw nres nkoj ntom ntom.
QSFP28
QSFP28 yog tsim los ua kom tau raws li 100G thov. Muaj plaub qhov kev kub ceev ntawm cov hluav taws xob sib txawv, thiab cov kis ntawm txhua channel yog 25Gbps txog 40Gbps. Nws tuaj yeem ua kom tau raws li kev thov ntawm 100G Ethernet (4 × 25Gbps) thiab EDR Infiniband. Muaj ntau hom QSFP28 cov khoom lag luam, thiab muaj ntau txoj hauv kev kom paub 100G kev xa mus, xws li 100G ncaj qha kev sib txuas, 100G rau 4-txoj kev 25G ceg txuas lossis 100G rau 2-txoj kev 50G ceg txuas.
Qhov sib txawv thiab zoo sib xws ntawm SFP, SFP +, SFP28, QSFP +, QSFP28
Tom qab nkag siab txog dab tsi yog SFP, SFP +, SFP28, QSFP +, QSFP28, peb yuav qhia qhov tshwj xeeb thiab qhov sib txawv ntawm ob.
SFPs thiab SFPs +: tib lub loj, txawv ceev thiab sib xws
Txij li thaum qhov loj me thiab cov tsos ntawm SFPs thiab SFPs + cov qauv zoo li qub, cov tuam txhab tsim khoom tuaj yeem lees txais qhov kev tsim lub cev ntawm SFPs rau ntawm cov kev hloov nrog SFPs + ports. Vim tias qhov loj me tib yam, ntau tus neeg siv khoom siv SFP module rau ntawm qhov chaw hloov' s SFP + chaw nres nkoj. Qhov kev ua haujlwm no ua tau, tab sis tus ceev yuav raug txo kom 1GBIT / s. Tsis tas li ntawd, nws yuav tsum raug sau tseg tias SFP + module tsis tuaj yeem siv rau hauv SFP slot, txwv tsis pub lub chaw nres nkoj lossis tus qauv yuav raug puas ntsoog. Ntxiv nrog rau qhov sib txawv hauv kev sib txuam, kis tau tus mob thiab cov qauv ntawm SFPs thiab SFPs + kuj tseem muaj qhov sib txawv. SFPs tuaj yeem xa tau 4GBIT / s nyob rau hauv feem ntau, thiab SFPs + tuaj yeem xa 10Gbit / s ntawm qhov ntau; SFPs ua raws li SFF -8472 raws tu qauv, thaum SFPs + ua raws li sff-8431 thiab SFF-8432 raws tu qauv.
SFP28 thiab SFP +: SFP28 optical module tuaj yeem siv rau hauv SFP + chaw nres nkoj
Raws li tau hais los saum no, SFP28 yog kev hloov kho tshiab ntawm SFP +, ob qho tib si muaj tib qho loj tab sis sib txawv ntawm cov nqi sib kis. Qhov kis tau tus mob ntawm SFP + yog 10Gbit / s, thiab hais tias ntawm SFP28 yog 25Gbit / s. Yog tias tus qauv kho qhov muag tau muab tso rau hauv qhov chaw nres nkoj SFP28, qhov sib kis tau sib kis yog 10Gbit / s, thiab hloov mus rau lwm tus. Ntxiv rau, qhov bandwidth ntawm SFP28 ncaj qha tooj liab cable ntau dua qhov ntawm SFP + ncaj qha tooj liab, thiab qhov poob qis dua.
SFP28 thiab QSFP28: cov qauv raws qauv sib txawv
Txawm hais tias ob qho tib si SFP28 thiab QSFP28 nqa tus lej" 28", lawv qhov ntau thiab tsawg thiab cov qauv txheej txheem sib txawv. SFP28 txhawb 25Gbit / s ib qho channel thiab QSFP28 txhawb nqa plaub 25Gbit / s raws. Ob qho ntawm lawv tuaj yeem siv rau hauv 100G network, tab sis kev siv hom yog txawv. QSFP28 tuaj yeem paub txog 100G kev xa mus los ntawm peb txoj kev tau hais los saum toj no, tab sis SFP28 yuav tsum cia siab rau cov ceg hluav taws xob loj ntawm QSFP28 txog SFP28.
QSFP thiab QSFP28: cov nqi sib txawv, siv ntau yam
QSFP + thiab QSFP28 optical module muaj qhov loj me ib yam thiab muaj plaub qhov sib txuas sib kis thiab tau txais cov channel. Tsis tas li ntawd, txawm hais tias QSFP + thiab QSFP28 series cov khoom kuj tseem muaj cov kho qhov muag thiab DAC / AOC cov xov tooj hluav taws xob ceev, cov nqi sib txawv. QSFP + module txhawb 40Gbit / s ib qho channel npaum li cas, thiab QSFP + DAC / AOC txhawb 4 × 10Gbit / s tus xa xov. QSFP28 module xa cov ntaub ntawv ntawm tus nqi ntawm 100Gbit / s, thiab QSFP28 DAC / AOC txhawb 4 × 25Gbit / s lossis 2 × 50Gbit / s. Nws yuav tsum raug sau tseg tias QSFP28 module tsis tuaj yeem siv rau 10G ceg txuas, tab sis yog tias qhov hloov nrog QSFP28 chaw nres nkoj txhawb QSFP + module, QSFP + module tuaj yeem tso rau hauv QSFP28 chaw nres nkoj kom paub txog 4 × 10G ceg txuas.
HTF' s cov khoom lag luam zoo tau lees tias, thiab cov khoom siv siv tau yog txawv txawv.
