QSFP ndi chiyani?

Small Form-Factor plugable (SFP)ndi compact, Hot-pluggable network interface module format yomwe imagwiritsidwa ntchito polumikizirana ndi ma data. Mawonekedwe a SFP pamanetiweki hardware ndi modular kagawo kwa transceiver TV yeniyeni, monga chingwe CHIKWANGWANI kapena chingwe mkuwa.[1] Ubwino wogwiritsa ntchito ma SFP poyerekeza ndi mawonekedwe osasunthika (mwachitsanzo zolumikizira modular mu masiwichi a Efaneti) ndikuti madoko amodzi amatha kukhala ndi mitundu yosiyanasiyana ya ma transceivers momwe amafunikira, ambiri kuphatikiza ma terminals opangira mizere, makhadi amtaneti, masiwichi ndi ma routers.

QSFP, yomwe imayimira Quad Small Form-factor plugable,ndimtundu wa ma transceiver module omwe amagwiritsidwa ntchito potumiza mwachangu kwambiri pazida zolumikizirana ndi maukonde, makamaka m'malo opangira ma data komanso malo opangira makompyuta ochita bwino kwambiri.. Zapangidwa kuti zizithandizira ma tchanelo angapo (nthawi zambiri anayi) ndipo zimatha kuthana ndi mitengo ya data kuyambira 10 Gbps mpaka 400 Gbps, kutengera mtundu wa module.

Kusintha kwa QSFP:

Muyezo wa QSFP wasintha pakapita nthawi, ndi mitundu yatsopano monga QSFP+, QSFP28, QSFP56, ndi QSFP-DD (Double Density) yopereka kuchuluka kwa data ndi kuthekera. Mabaibulo atsopanowa amamanga pamapangidwe oyambilira a QSFP kuti akwaniritse zomwe zikukulirakulira kwa bandwidth komanso kuthamanga kwachangu pama network amakono.

Zofunikira zazikulu za QSFP:

• Kuchulukana Kwambiri:

Ma module a QSFP amapangidwa kuti azikhala ophatikizika, kulola kuchuluka kwa maulumikizidwe pamalo ang'onoang'ono.

• Chowotchera:

Atha kulowetsedwa ndi kuchotsedwa pachipangizo chikayatsidwa, osayambitsa kusokoneza maukonde.

• Njira zingapo:

Ma module a QSFP nthawi zambiri amakhala ndi njira zinayi, iliyonse yomwe imatha kutumiza deta, kulola kukwera kwa bandwidth ndi ma data.

• Ma Data Osiyanasiyana:

Pali mitundu yosiyanasiyana ya QSFP, monga QSFP+, QSFP28, QSFP56, ndi QSFP-DD, yomwe imathandizira kuthamanga kosiyana kuchokera ku 40Gbps mpaka 400Gbps ndi kupitirira.

• Ntchito Zosiyanasiyana:

Ma module a QSFP amagwiritsidwa ntchito pazinthu zosiyanasiyana, kuphatikizapo ma data center interconnects, high-performance computing, and telecommunication networks.

• Zosankha za Copper ndi Fiber Optic:

Ma module a QSFP angagwiritsidwe ntchito ndi zingwe zonse zamkuwa (Direct Attach Cables kapena DACs) ndi zingwe za fiber optic.

40 Gbit/s (QSFP+)

QSFP+ ndi chisinthiko cha QSFP kuthandizira njira zinayi za 10 Gbit/s zonyamula 10 Gigabit Ethernet, 10GFC Fiber Channel, kapena QDR InfiniBand. Makanema anayi amathanso kuphatikizidwa kukhala ulalo umodzi wa 40 Gigabit Ethernet.

50 Gbit/s (QSFP14)

Muyezo wa QSFP14 wapangidwa kuti uzinyamula FDR InfiniBand, SAS-3 kapena 16G Fiber Channel.

100 Gbit/s (QSFP28)

Muyezo wa QSFP28 wapangidwa kuti uzinyamula 100 Gigabit Ethernet, EDR InfiniBand, kapena 32G Fiber Channel. Nthawi zina mtundu wa transceiver uwu umatchedwanso QSFP100 kapena 100G QSFP chifukwa cha kuphweka.

200 Gbit/s (QSFP56)

QSFP56 idapangidwa kuti izinyamula 200 Gigabit Ethernet, HDR InfiniBand, kapena 64G Fiber Channel. Chowonjezera chachikulu ndichakuti QSFP56 imagwiritsa ntchito magawo anayi a pulse-amplitude modulation (PAM-4) m'malo mwa non-return-to-zero (NRZ). Imagwiritsa ntchito mawonekedwe akuthupi omwewo monga QSFP28 (SFF-8665), yokhala ndi mphamvu zamagetsi kuchokera ku SFF-8024 ndi revision 2.10a ya SFF-8636. Nthawi zina mtundu wa transceiver uwu umatchedwa 200G QSFP chifukwa cha kuphweka.

KCO Fiber imapereka mawonekedwe apamwamba a fiber optic module SFP, SFP +, XFP, SFP28, QSFP, QSFP +, QSFP28. QSFP56, QSFP112, AOC, ndi DAC, zomwe zimatha kugwirizana ndi masinthidwe ambiri monga Cisco, Huawei, H3C, ZTE, Juniper, Arista, HP, ... etc. Chonde lumikizanani ndi gulu lathu lamalonda kuti mupeze chithandizo chabwino kwambiri pankhani yaukadaulo komanso mtengo.
