QSFP ke eng?

SFP (SFP)ke mofuta oa mojule oa khokahanyo oa marang-rang o kopaneng, o chesang, o sebelisoang bakeng sa lits'ebetso tsa likhokahano tsa mehala le data. Khokahano ea SFP mabapi le lisebelisoa tsa marang-rang ke sekotjana sa modular bakeng sa transceiver e ikhethileng ea media, joalo ka thapo ea fiber-optic kapa thapo ea koporo.[1] Molemo oa ho sebelisa li-SFP ha li bapisoa le li-interfaces tse tsitsitseng (mohlala, li-modular connectors ho li-switch tsa Ethernet) ke hore likou ka bomong li ka ba le mefuta e fapaneng ea li-transceivers kamoo ho hlokahalang, 'me bongata bo kenyelletsa li-terminals tsa optical line, likarete tsa marang-rang, li-switches le li-routers.

QSFP, e emelang Quad Small Form-factor plugable,kemofuta oa mochini oa transceiver o sebelisetsoang phetiso ea data e potlakileng ho lisebelisoa tsa marang-rang, haholo-holo litsing tsa data le tikolohong ea ts'ebetso e phahameng ea komporo.. E etselitsoe ho ts'ehetsa likanale tse ngata (hangata tse nne) mme e khona ho sebetsana le litefiso tsa data ho tloha ho 10 Gbps ho isa ho 400 Gbps, ho latela mofuta o itseng oa mojule.

Phetoho ea QSFP:

Tekanyetso ea QSFP e fetohile ha nako e ntse e ea, ka liphetolelo tse ncha tse kang QSFP+, QSFP28, QSFP56, le QSFP-DD (Double Density) e fanang ka litekanyetso tse eketsehileng tsa data le bokhoni. Liphetolelo tsena tse ncha li theha moralo oa QSFP oa mantlha ho fihlela litlhoko tse ntseng li hola tsa bandwidth e phahameng le lebelo le potlakileng ho marang-rang a sejoale-joale.

Lintlha tsa bohlokoa tsa QSFP:

• Tekano e Phahameng:

Li-module tsa QSFP li etselitsoe hore li kopane, tse lumellang palo e phahameng ea likhokahano sebakeng se batlang se le senyenyane.

• Hot-plugable:

Li ka kenngoa le ho tlosoa sesebelisoa ha se ntse se sebelisoa, ntle le ho baka tšitiso ho marang-rang.

• Mecha e mengata:

Li-module tsa QSFP hangata li na le likanale tse 'ne, e' ngoe le e 'ngoe e khona ho fetisa data, e lumellang hore ho be le litekanyetso tse phahameng tsa bandwidth le data.

• Litefiso tse fapaneng tsa data:

Ho na le mefuta e fapaneng ea QSFP, e kang QSFP+, QSFP28, QSFP56, le QSFP-DD, e tšehetsang lebelo le fapaneng ho tloha 40Gbps ho ea 400Gbps le ho feta.

• Lisebelisoa tse fapaneng:

Li-module tsa QSFP li sebelisoa mefuteng e mengata ea lits'ebetso, ho kenyelletsa le likhokahano tsa setsi sa data, likhomphutha tse sebetsang hantle haholo, le marang-rang a mehala ea puisano.

• Likhetho tsa Copper le Fiber Optic:

Li-module tsa QSFP li ka sebelisoa ka lithapo tse peli tsa koporo (Direct Attach Cables kapa DACs) le likhoele tsa fiber optic.

40 Gbit/s (QSFP+)

QSFP+ ke phetoho ea QSFP ho tšehetsa likanale tse 'nè tsa 10 Gbit/s tse nang le 10 Gigabit Ethernet, 10GFC Fiber Channel, kapa QDR InfiniBand. Likanale tse 4 le tsona li ka kopanngoa hore e be sehokelo se le seng sa 40 Gigabit Ethernet.

50 Gbit/s (QSFP14)

Tekanyetso ea QSFP14 e etselitsoe ho tsamaisa FDR InfiniBand, SAS-3 kapa 16G Fiber Channel.

100 Gbit/s (QSFP28)

Tekanyetso ea QSFP28 e etselitsoe ho jara 100 Gigabit Ethernet, EDR InfiniBand, kapa 32G Fiber Channel. Ka linako tse ling mofuta ona oa transceiver o boetse o bitsoa QSFP100 kapa 100G QSFP molemong oa ho nolofatsa.

200 Gbit/s (QSFP56)

QSFP56 e etselitsoe ho tsamaisa 200 Gigabit Ethernet, HDR InfiniBand, kapa 64G Fiber Channel. Ntlafatso e kholo ka ho fetisisa ke hore QSFP56 e sebelisa modulation ea maemo a mane ea pulse-amplitude (PAM-4) ho fapana le ho se khutlele ho zero (NRZ). E sebelisa litlhaloso tsa 'mele tse tšoanang le QSFP28 (SFF-8665), e nang le litlhaloso tsa motlakase ho tloha ho SFF-8024 le revision 2.10a ea SFF-8636. Ka linako tse ling mofuta ona oa transceiver o bitsoa 200G QSFP molemong oa ho nolofatsa.

KCO Fiber e fana ka boleng bo phahameng ba fiber optic module SFP, SFP +, XFP, SFP28, QSFP, QSFP +, QSFP28. QSFP56, QSFP112, AOC, le DAC, e ka tsamaellanang le mefuta e mengata ea li-switches tse kang Cisco, Huawei, H3C, ZTE, Juniper, Arista, HP, ... joalo-joalo. Ka kopo ikopanye le sehlopha sa rona sa barekisi ho fumana tšehetso e ntle ka ho fetisisa mabapi le taba ea tekheniki le litheko.
