QSFP ni iki?

Ifishi ntoya-ishobora gucomeka (SFP)ni uburyo bworoshye, bushyushye-bushyirwa kumurongo interineti module ikoreshwa muburyo bwitumanaho hamwe namakuru yo gutumanaho amakuru. Imigaragarire ya SFP ku byuma bikoresha imiyoboro ni uburyo bwa moderi ya transceiver yihariye itangazamakuru, nko kuri fibre optique cyangwa umugozi wumuringa. Ibyiza byo gukoresha SFP ugereranije ninteruro zifatika (urugero: modular ihuza moderi muri Ethernet yahinduwe) nuko ibyambu byumuntu bishobora kuba bifite ubwoko butandukanye bwa transcevers nkuko bisabwa, hamwe nabenshi harimo umurongo wa optique, amakarita y'urusobe, switch na router.

QSFP, igereranya Quad Ntoya Ifishi-Ikintu Cyoroshye,niubwoko bwa transceiver module ikoreshwa muburyo bwihuse bwo kohereza amakuru mubikoresho byurusobe, cyane cyane mubigo byamakuru hamwe nibidukikije bikora neza. Yashizweho kugirango ishyigikire imiyoboro myinshi (mubisanzwe bine) kandi irashobora gukora igipimo cyamakuru kuva kuri 10 Gbps kugeza 400 Gbps, bitewe n'ubwoko bwihariye bwa module.

Ubwihindurize bwa QSFP:

Ibipimo bya QSFP byahindutse mugihe, hamwe na verisiyo nshya nka QSFP +, QSFP28, QSFP56, na QSFP-DD (Ubucucike bubiri) itanga ibipimo byubushobozi hamwe nubushobozi. Izi verisiyo nshya zubakiye ku gishushanyo mbonera cya QSFP kugirango zuzuze ibisabwa byiyongera ku muvuduko mwinshi kandi wihuta mu miyoboro igezweho.

Ibyingenzi byingenzi bya QSFP:

• Ubucucike bukabije:

QSFP module yagenewe guhuzagurika, itanga umubare munini wibihuza mumwanya muto.

• Bishyushye:

Birashobora kwinjizwa no gukurwa mubikoresho mugihe bikoreshwa, bitarinze guhungabanya umuyoboro.

• Imiyoboro myinshi:

QSFP module isanzwe ifite imiyoboro ine, buri kimwe gishobora kohereza amakuru, cyemerera umurongo mugari hamwe nigipimo cyamakuru.

• Ibiciro bitandukanye byamakuru:

Impinduka zitandukanye za QSFP zirahari, nka QSFP +, QSFP28, QSFP56, na QSFP-DD, zishyigikira umuvuduko utandukanye kuva 40Gbps kugeza 400Gbps na nyuma yaho.

• Porogaramu zitandukanye:

QSFP module ikoreshwa muburyo butandukanye bwa porogaramu, harimo guhuza amakuru hagati yamakuru, kubara cyane-kubara, hamwe numuyoboro witumanaho.

• Amahitamo y'umuringa na fibre optique:

QSFP modules irashobora gukoreshwa hamwe ninsinga zombi z'umuringa (Direct Attach Cables or DACs) hamwe na fibre optique.

40 Gbit / s (QSFP +)

QSFP + ni ubwihindurize bwa QSFP kugirango ishyigikire imiyoboro ine 10 ya Gbit / s itwara 10 Gigabit Ethernet, Umuyoboro wa Fibre 10GFC, cyangwa QDR InfiniBand. Imiyoboro 4 irashobora kandi guhurizwa hamwe muri 40 ya Gigabit Ethernet.

50 Gbit / s (QSFP14)

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

100 Gbit / s (QSFP28)

Igipimo cya QSFP28 cyagenewe gutwara 100 Gigabit Ethernet, EDR InfiniBand, cyangwa Umuyoboro wa Fibre 32G. Rimwe na rimwe, ubu bwoko bwa transceiver nabwo bwitwa QSFP100 cyangwa 100G QSFP kubworoshye.

200 Gbit / s (QSFP56)

QSFP56 yagenewe gutwara 200 Gigabit Ethernet, HDR InfiniBand, cyangwa Umuyoboro wa Fibre 64G. Iterambere rikomeye ni uko QSFP56 ikoresha modula enye zo mu bwoko bwa pulse-amplitude modulation (PAM-4) aho kudasubira kuri zeru (NRZ). Ikoresha ibisobanuro bifatika nka QSFP28 (SFF-8665), hamwe nibisobanuro byamashanyarazi kuva SFF-8024 no gusubiramo 2.10a ya SFF-8636. Rimwe na rimwe, ubu bwoko bwa transceiver bwitwa 200G QSFP kubworoshye.

KCO Fibre itanga ubuziranenge bwa fibre optique module SFP, SFP +, XFP, SFP28, QSFP, QSFP +, QSFP28. QSFP56, QSFP112, AOC, na DAC, birashobora guhuzwa nibirango byinshi byahinduwe nka Cisco, Huawei, H3C, ZTE, Juniper, Arista, HP,… nibindi. Saba kuvugana nitsinda ryacu ryo kugurisha kugirango ubone inkunga nziza kubibazo bya tekiniki kandi nigiciro.
