Kodi QSFP ndi chiyani?

Cholumikizira Chaching'ono cha Fomu-Chinthu (SFP)ndi mawonekedwe ang'onoang'ono, otentha olumikizirana ndi netiweki omwe amagwiritsidwa ntchito polumikizirana ndi mauthenga komanso mauthenga a data. Mawonekedwe a SFP pa hardware ya netiweki ndi malo olumikizirana a transceiver yeniyeni, monga chingwe cha fiber-optic kapena chingwe cha mkuwa.[1] Ubwino wogwiritsa ntchito ma SFP poyerekeza ndi ma interface okhazikika (monga zolumikizira za modular mu switch za Ethernet) ndikuti ma doko amodzi amatha kukhala ndi mitundu yosiyanasiyana ya ma transceiver momwe amafunikira, ndipo ambiri a iwo akuphatikizapo ma terminal a optical line, ma network card, ma switch ndi ma router.

QSFP, yomwe imayimira Quad Small Form-factor Pluggable,ndimtundu wa gawo la transceiver lomwe limagwiritsidwa ntchito potumiza deta mwachangu kwambiri m'zida zolumikizirana, makamaka m'malo osungira deta ndi malo ogwiritsira ntchito makompyuta apamwambaYapangidwa kuti izithandiza njira zingapo (nthawi zambiri zinayi) ndipo imatha kuthana ndi kuchuluka kwa deta kuyambira 10 Gbps mpaka 400 Gbps, kutengera mtundu wa module inayake.

Kusintha kwa QSFP:

Muyezo wa QSFP wasintha pakapita nthawi, ndipo mitundu yatsopano monga QSFP+, QSFP28, QSFP56, ndi QSFP-DD (Double Density) imapereka kuchuluka kwa data ndi kuthekera kowonjezera. Mitundu yatsopanoyi imamangidwa pa kapangidwe koyambirira ka QSFP kuti ikwaniritse zosowa zomwe zikukula za bandwidth yayikulu komanso liwiro lachangu m'maukonde amakono.

Zinthu Zazikulu za QSFP:

• Kuchuluka Kwambiri:

Ma module a QSFP apangidwa kuti akhale ang'onoang'ono, zomwe zimathandiza kuti pakhale kulumikizana kwakukulu pamalo ochepa.

• Yotentha-Yotha Kuphwanyidwa:

Zitha kuyikidwa ndikuchotsedwa mu chipangizocho chikagwiritsidwa ntchito, popanda kusokoneza netiweki.

• Ma Channels Angapo:

Ma module a QSFP nthawi zambiri amakhala ndi njira zinayi, iliyonse yomwe imatha kutumiza deta, zomwe zimapangitsa kuti bandwidth ndi data zikwere kwambiri.

• Mitengo Yosiyanasiyana ya Deta:

Pali mitundu yosiyanasiyana ya QSFP, monga QSFP+, QSFP28, QSFP56, ndi QSFP-DD, zomwe zimathandiza kuthamanga kosiyana kuyambira 40Gbps mpaka 400Gbps ndi kupitirira apo.

• Ntchito Zosiyanasiyana:

Ma module a QSFP amagwiritsidwa ntchito m'njira zosiyanasiyana, kuphatikizapo ma data center interconnects, high-performance computing, ndi ma telecommunication networks.

• Zosankha za Copper ndi Fiber Optic:

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

40 Gbit/s (QSFP+)

QSFP+ ndi kusintha kwa QSFP komwe kungathandize njira zinayi za 10 Gbit/s zomwe zili ndi 10 Gigabit Ethernet, 10GFC Fiber Channel, kapena QDR InfiniBand. Njira zinayizi zitha kuphatikizidwanso kukhala ulalo umodzi wa 40 Gigabit Ethernet.

50 Gbit/s (QSFP14)

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

100 Gbit/s (QSFP28)

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

200 Gbit/s (QSFP56)

QSFP56 yapangidwa kuti inyamule 200 Gigabit Ethernet, HDR InfiniBand, kapena 64G Fiber Channel. Chowonjezera chachikulu ndichakuti QSFP56 imagwiritsa ntchito ma modulation a pulse-amplitude a ma level anayi (PAM-4) m'malo mwa non-return-to-zero (NRZ). Imagwiritsa ntchito ma physical specifications omwewo monga QSFP28 (SFF-8665), okhala ndi ma electrical specifications ochokera ku SFF-8024 ndi revision 2.10a ya SFF-8636. Nthawi zina transceiver yamtunduwu imatchedwa 200G QSFP chifukwa cha kuphweka.

KCO Fiber imapereka module ya fiber optic yapamwamba kwambiri ya SFP, SFP+, XFP, SFP28, QSFP, QSFP+, QSFP28. QSFP56, QSFP112, AOC, ndi DAC, zomwe zimagwirizana ndi ma switch ambiri monga Cisco, Huawei, H3C, ZTE, Juniper, Arista, HP, ... ndi zina zotero. Chonde funsani gulu lathu logulitsa kuti mupeze chithandizo chabwino kwambiri pamavuto aukadaulo komanso mtengo.
