QSFP ke eng?

Sesebelisoa se Nyenyane se ka Pluggable (SFP)ke sebopeho sa module ya sebopeho sa marang-rang se kopaneng, se ka hokeloang ka ho tjhesa se sebediswang bakeng sa ditshebediso tsa puisano le tsa puisano ya data. Sebopeho sa SFP hodima hardware ya marang-rang ke sebaka sa modular bakeng sa transceiver e ikgethang ya media, jwalo ka thapo ya fiber-optic kapa thapo ya koporo.[1] Molemo wa ho sebedisa di-SFP ha di bapiswa le di-interface tse tsitsitseng (mohlala, dihokelo tsa modular ho di-switch tsa Ethernet) ke hore di-port ka bomong di ka hlomellwa ka mefuta e fapaneng ya di-transceiver ha ho hlokahala, mme boholo ba tsona di kenyeletsa di-terminal tsa mohala wa optical, dikarete tsa marang-rang, di-switch le di-router.

QSFP, e emelang Quad Small Form-factor Pluggable,kemofuta oa mojule oa transceiver o sebelisetsoang phetiso ea data e potlakileng haholo lisebelisoa tsa marang-rang, haholo-holo litsing tsa data le libakeng tsa k'homphieutha tse sebetsang hantle.E etselitsoe ho tšehetsa liteishene tse ngata (hangata tse 'ne) 'me e ka sebetsana le litefiso tsa data tse tlohang ho 10 Gbps ho isa ho 400 Gbps, ho latela mofuta o itseng oa mojule.

Tsoelo-pele ea QSFP:

Tekanyetso ea QSFP e fetohile ha nako e ntse e ea, ka mefuta e mecha e kang QSFP+, QSFP28, QSFP56, le QSFP-DD (Double Density) e fanang ka litefiso tse eketsehileng tsa data le bokhoni. Mefuta ena e mecha e hahella holim'a moralo oa pele oa QSFP ho fihlela litlhoko tse ntseng li hola tsa bandwidth e phahameng le lebelo le potlakileng marangrang a sejoale-joale.

Likarolo tsa bohlokoa tsa QSFP:

• Boima bo Phahameng:

Li-module tsa QSFP li etselitsoe ho ba tse nyane, tse lumellang palo e kholo ea likhokahano sebakeng se senyenyane.

• E ka phutholohang ka ho Chesa:

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

• Likanale tse ngata:

Hangata di-module tsa QSFP di na le dikanale tse nne, e nngwe le e nngwe e kgona ho fetisa data, e leng se lumellang bandwidth e phahameng le ditefiso tsa data.

• Litefiso tse fapaneng tsa data:

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

• Likopo tse Feto-fetohang:

Li-module tsa QSFP li sebelisoa lits'ebetsong tse fapaneng, ho kenyeletsoa likhokahano tsa setsi sa data, khomphutha e sebetsang hantle, le marang-rang a puisano.

• Likhetho tsa Koporo le Fiber Optic:

Li-module tsa QSFP li ka sebelisoa ka likhoele tsa koporo ka bobeli (Likhoele tsa ho Kopanya ka ho Otloloha kapa li-DAC) le likhoele tsa fiber optic.

40 Gbit/s (QSFP+)

QSFP+ ke phetoho ea QSFP ho tšehetsa liteishene tse 'ne tsa 10 Gbit/s tse nang le 10 Gigabit Ethernet, 10GFC Fiber Channel, kapa QDR InfiniBand. Liteishene tsena tse 4 li ka boela tsa kopanngoa ho ba sehokelo se le seng sa 40 Gigabit Ethernet.

50 Gbit/s (QSFP14)

Tekanyetso ea QSFP14 e etselitsoe ho jara 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 bonolo.

200 Gbit/s (QSFP56)

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

KCO Fiber e fana ka boleng bo holimo ba module ea fiber optic SFP, SFP+, XFP, SFP28, QSFP, QSFP+, QSFP28. QSFP56, QSFP112, AOC, le DAC, tse ka lumellanang le boholo ba switch joalo ka Cisco, Huawei, H3C, ZTE, Juniper, Arista, HP, ... jj. Ka kopo ikopanye le sehlopha sa rona sa thekiso ho fumana tšehetso e ntle ka ho fetisisa mabapi le bothata ba tekheniki le theko.
