QSFP ni iki?

Ishobora gukubitwamo ibice bito (SFP)ni module ntoya kandi ishyushye yo guhuza imiyoboro y'itumanaho ikoreshwa haba muri porogaramu z'itumanaho n'itumanaho ry'amakuru. Interineti ya SFP ku bikoresho by'itumanaho ni module ikoreshwa kuri transceiver yihariye y'itangazamakuru, nko kuri insinga ya fiber-optic cyangwa insinga y'umuringa.[1] Akamaro ko gukoresha SFP ugereranije na interfaces zidahinduka (urugero: modular connectors muri switches za Ethernet) ni uko ports imwe imwe ishobora gushyirwamo ubwoko butandukanye bwa transceivers uko bikenewe, aho inyinshi muri zo zirimo imiyoboro y'umurongo wa optique, amakarita ya network, switches na routers.

QSFP, bisobanura Quad Small Form-factor Pluggable,niubwoko bwa module ya transceiver ikoreshwa mu kohereza amakuru yihuta cyane mu bikoresho by'itumanaho, cyane cyane mu bigo by'amakuru n'ahantu hakora mudasobwa hifashishijwe ikoranabuhanga rihambayeYagenewe gushyigikira imiyoboro myinshi (ubusanzwe ine) kandi ishobora guhangana n'umuvuduko w'amakuru uri hagati ya 10 Gbps na 400 Gbps, bitewe n'ubwoko bwa module runaka.

Iterambere rya QSFP:

Uburyo bwa QSFP bugenda butera imbere uko igihe cyagiye gihita, aho verisiyo nshya nka QSFP+, QSFP28, QSFP56, na QSFP-DD (Double Density) zitanga umusaruro wiyongereye ku gipimo cy’amakuru n’ubushobozi. Izi verisiyo nshya zubatswe ku gishushanyo cya QSFP cya mbere kugira ngo zihuze n’ibikenewe byiyongera byo gukoresha bandwidth nyinshi n’umuvuduko wihuta mu miyoboro igezweho.

Ibiranga by'ingenzi bya QSFP:

• Ubucucike Bunini:

Moduli za QSFP zakozwe ku buryo ziciriritse, bigatuma habaho umubare munini w'itumanaho mu mwanya muto.

• Ishyushye cyane:

Bishobora kwinjiza no gukurwa mu gikoresho mu gihe gikoresha, bitabangamiye umuyoboro.

• Imiyoboro myinshi:

Muri rusange module za QSFP zifite imiyoboro ine, buri imwe ikaba ishobora kohereza amakuru, bigatuma habaho bandwidth n'umuvuduko w'amakuru biri hejuru.

• Ibiciro bitandukanye by'amakuru:

Hari ubwoko butandukanye bwa QSFP, nka QSFP+, QSFP28, QSFP56, na QSFP-DD, bushyigikira umuvuduko utandukanye kuva kuri 40Gbps kugeza kuri 400Gbps no hejuru yayo.

• Porogaramu zikoreshwa mu buryo butandukanye:

Moduli za QSFP zikoreshwa mu buryo butandukanye, harimo imiyoboro y’itumanaho, ikoranabuhanga rigezweho, n’itumanaho.

• Amahitamo ya Copper na Fiber Optic:

Moduli za QSFP zishobora gukoreshwa hamwe n'insinga z'umuringa (Direct Attach Cables cyangwa DACs) hamwe n'insinga za fiber optique.

40 Gbit/s (QSFP+)

QSFP+ ni iterambere rya QSFP rigamije gushyigikira imiyoboro ine ya Gbit/s 10 ifite Gigabit Ethernet 10, 10GFC Fiber Channel, cyangwa QDR InfiniBand. Imiyoboro ine ishobora kandi guhuzwa mu muyoboro umwe wa Gigabit Ethernet 40.

50 Gbit/s (QSFP14)

Igipimo cya QSFP14 cyagenewe gutwara umuyoboro wa FDR InfiniBand, SAS-3 cyangwa 16G Fiber.

100 Gbit/s (QSFP28)

Igipimo cya QSFP28 cyagenewe gutwara 100 Gigabit Ethernet, EDR InfiniBand, cyangwa 32G Fiber Channel. Hari igihe ubu bwoko bwa transceiver bunatwa QSFP100 cyangwa 100G QSFP kugira ngo byorohe.

200 Gbit/s (QSFP56)

QSFP56 yagenewe gutwara Ethernet ya Gigabit 200, HDR InfiniBand, cyangwa 64G Fiber Channel. Iterambere rikomeye ni uko QSFP56 ikoresha modulation ya pulse-amplitude y’urwego rune (PAM-4) aho gukoresha non-return-to-zero (NRZ). Ikoresha imiterere imwe n’iya QSFP28 (SFF-8665), hamwe n’imiterere y’amashanyarazi ya SFF-8024 na revision 2.10a ya SFF-8636. Hari igihe ubu bwoko bwa transceiver bwitwa 200G QSFP kugira ngo byorohe.

KCO Fiber itanga module nziza ya fiber optic SFP, SFP+, XFP, SFP28, QSFP, QSFP+, QSFP28. QSFP56, QSFP112, AOC, na DAC, ishobora kuba ihuye n'ubwoko bwinshi bwa switch nka Cisco, Huawei, H3C, ZTE, Juniper, Arista, HP,…nibindi. Nyamuneka hamagara itsinda ryacu rishinzwe ubucuruzi kugira ngo ubone ubufasha bwiza ku kibazo cya tekiniki n'igiciro.
