QSFP yog dab tsi?

Small Form-Factor Pluggable (SFP)yog ib qho compact, kub-pluggable network interface module hom siv rau kev sib txuas lus thiab cov ntaub ntawv kev sib txuas lus. Ib qho SFP interface ntawm kev sib txuas lus kho vajtse yog qhov modular rau cov xov xwm tshwj xeeb transceiver, xws li rau fiber ntau-optic cable lossis tooj liab cable.[1] Qhov kom zoo dua ntawm kev siv SFPs piv rau cov kev sib txuas ruaj khov (xws li modular connectors hauv Ethernet keyboards) 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 hluav taws xob kho qhov muag, phaib network, keyboards thiab routers.

QSFP, uas sawv cev rau Quad Small Form-factor Pluggable,yogib hom transceiver module siv rau high-speed cov ntaub ntawv kis tau tus mob nyob rau hauv networking pab kiag li lawm, tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv chaw zov me nyuam thiab high-kev ua tau zoo xam qhov chaw.. Nws tau tsim los txhawb ntau txoj kev (feem ntau yog plaub) thiab tuaj yeem tswj cov ntaub ntawv tus nqi xws li 10 Gbps txog 400 Gbps, nyob ntawm seb hom module tshwj xeeb.

Evolution ntawm QSFP:

QSFP tus qauv tau hloov zuj zus mus rau lub sijhawm, nrog cov qauv tshiab xws li QSFP +, QSFP28, QSFP56, thiab QSFP-DD (Double Density) muab cov ntaub ntawv nce ntxiv thiab muaj peev xwm. Cov qauv tshiab no tsim los ntawm QSFP tus qauv tsim los ua kom tau raws li qhov kev xav tau loj dua rau kev siv bandwidth ntau dua thiab nrawm dua hauv cov tes hauj lwm niaj hnub no.

Cov yam ntxwv tseem ceeb ntawm QSFP:

• High-Density:

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

• Kub-Pluggable:

Lawv tuaj yeem muab tso thiab tshem tawm los ntawm ib lub cuab yeej thaum nws qhib, tsis muaj kev cuam tshuam rau lub network.

• Ntau Channels:

QSFP modules feem ntau muaj plaub txoj hauv kev, txhua tus muaj peev xwm xa cov ntaub ntawv, tso cai rau ntau dua bandwidth thiab cov ntaub ntawv tus nqi.

• Ntau cov ntaub ntawv tus nqi:

QSFP sib txawv muaj nyob, xws li QSFP +, QSFP28, QSFP56, thiab QSFP-DD, txhawb kev sib txawv ntawm 40Gbps mus rau 400Gbps thiab tshaj.

• Kev siv ntau yam:

QSFP modules tau siv dav hauv ntau daim ntawv thov, suav nrog cov ntaub ntawv chaw sib cuam tshuam, kev suav ua haujlwm siab, thiab kev sib txuas lus sib txuas lus.

• Copper thiab Fiber Optic Options:

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

40 Gbit / s (QSFP +)

QSFP + yog qhov hloov pauv ntawm QSFP los txhawb plaub 10 Gbit / s raws nqa 10 Gigabit Ethernet, 10GFC Fiber Channel, lossis QDR InfiniBand. 4 channel kuj tseem tuaj yeem ua ke rau hauv ib qho 40 Gigabit Ethernet txuas.

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 lub sij hawm hom transceiver no tseem hu ua 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 QSFP56 siv plaub theem pulse-amplitude modulation (PAM-4) es tsis txhob rov qab-rau-zero (NRZ). Nws siv tib lub cev tshwj xeeb raws li QSFP28 (SFF-8665), nrog rau cov khoom siv hluav taws xob los ntawm SFF-8024 thiab kho 2.10a ntawm SFF-8636. Qee zaum hom transceiver no raug xa mus rau 200G QSFP rau kev yooj yim.

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