QSFP yog dab tsi?

Cov Qauv Me Me Pluggable (SFP)yog ib hom ntawv me me, siv tau rau kev sib txuas lus thiab kev sib txuas lus ntawm cov ntaub ntawv. Ib qho SFP interface ntawm cov khoom siv networking yog ib qho modular slot rau ib qho media-specific transceiver, xws li rau ib qho fiber-optic cable lossis ib qho tooj liab cable.[1] Qhov zoo ntawm kev siv SFPs piv rau cov interfaces ruaj khov (piv txwv li modular connectors hauv Ethernet switches) yog tias cov chaw nres nkoj ib leeg tuaj yeem nruab nrog ntau hom transceivers raws li qhov xav tau, nrog rau feem ntau suav nrog cov kab optical line terminals, network cards, switches thiab routers.

QSFP, uas sawv cev rau Quad Small Form-factor Pluggable,yogib hom transceiver module siv rau kev xa cov ntaub ntawv ceev ceev hauv cov khoom siv networking, tshwj xeeb tshaj yog nyob rau hauv cov chaw khaws ntaub ntawv thiab cov chaw ua haujlwm siab.Nws tau tsim los txhawb ntau txoj kev sib txuas (feem ntau yog plaub) thiab tuaj yeem tswj cov nqi ntaub ntawv xws li 10 Gbps txog 400 Gbps, nyob ntawm hom module tshwj xeeb.

Kev Hloov Pauv ntawm QSFP:

Tus qauv QSFP tau hloov zuj zus mus raws sijhawm, nrog rau cov qauv tshiab xws li QSFP +, QSFP28, QSFP56, thiab QSFP-DD (Double Density) muab cov ntaub ntawv ceev thiab muaj peev xwm ntau dua. Cov qauv tshiab no tsim los ntawm tus qauv QSFP thawj zaug kom tau raws li qhov xav tau ntawm bandwidth siab dua thiab ceev dua hauv cov tes hauj lwm niaj hnub no.

Cov yam ntxwv tseem ceeb ntawm QSFP:

• Kev Ceev Ceev:

QSFP modules yog tsim los kom me me, uas tso cai rau ntau qhov kev sib txuas hauv qhov chaw me me.

• Kub-Pluggable:

Lawv tuaj yeem muab ntxig thiab tshem tawm ntawm lub cuab yeej thaum nws qhib, yam tsis ua rau muaj kev cuam tshuam rau lub network.

• Ntau Txoj Kev:

QSFP modules feem ntau muaj plaub txoj kab ke, txhua tus muaj peev xwm xa cov ntaub ntawv, uas ua rau muaj bandwidth thiab cov ntaub ntawv ntau dua.

• Ntau Cov Nqi Ntaub Ntawv:

Muaj ntau hom QSFP sib txawv, xws li QSFP+, QSFP28, QSFP56, thiab QSFP-DD, txhawb nqa ntau yam ceev txij li 40Gbps txog 400Gbps thiab dhau ntawd.

• Cov Ntawv Thov Ntau Yam:

QSFP modules siv rau ntau yam kev siv, suav nrog kev sib txuas ntawm cov chaw khaws ntaub ntawv, kev suav lej ua tau zoo, thiab kev sib txuas lus hauv xov tooj.

• Cov Kev Xaiv Tooj Liab thiab Fiber Optic:

Cov QSFP modules siv tau nrog ob qho tib si tooj liab cables (Direct Attach Cables lossis DACs) thiab fiber optic cables.

40 Gbit/s (QSFP+)

QSFP+ yog ib qho kev hloov pauv ntawm QSFP los txhawb plaub txoj kab 10 Gbit/s uas nqa 10 Gigabit Ethernet, 10GFC Fiber Channel, lossis QDR InfiniBand. 4 txoj kab no kuj tseem tuaj yeem ua ke ua ib qho txuas 40 Gigabit Ethernet.

50 Gbit/s (QSFP14)

Tus qauv QSFP14 yog tsim los nqa FDR InfiniBand, SAS-3 lossis 16G Fiber Channel.

100 Gbit/s (QSFP28)

Tus qauv QSFP28 yog tsim los nqa 100 Gigabit Ethernet, EDR InfiniBand, lossis 32G Fiber Channel. Qee zaum hom transceiver no kuj raug xa mus rau QSFP100 lossis 100G QSFP rau kev yooj yim.

200 Gbit/s (QSFP56)

QSFP56 yog tsim los nqa 200 Gigabit Ethernet, HDR InfiniBand, lossis 64G Fiber Channel. Qhov kev txhim kho loj tshaj plaws yog tias QSFP56 siv plaub-qib pulse-amplitude modulation (PAM-4) es tsis yog non-return-to-zero (NRZ). Nws siv tib lub cev specifications li QSFP28 (SFF-8665), nrog rau hluav taws xob specifications los ntawm SFF-8024 thiab kev kho dua tshiab 2.10a ntawm SFF-8636. Qee zaum hom transceiver no hu ua 200G QSFP rau kev yooj yim.

KCO Fiber muab cov khoom siv fiber optic zoo SFP, SFP +, XFP, SFP28, QSFP, QSFP +, QSFP28. QSFP56, QSFP112, AOC, thiab DAC, uas tuaj yeem sib xws nrog feem ntau ntawm cov hom hloov xws li Cisco, Huawei, H3C, ZTE, Juniper, Arista, HP, ... thiab lwm yam.
