Waa maxay QSFP?

Foomka-Arrinta Yar ee Pluggable (SFP)waa qaab qaabaysan qaab-dhismeedka shabakad-kulul-kulul oo loo isticmaalo isgaadhsiinta iyo isgaadhsiinta xogta labadaba. Interface-ka SFP ee qalabka isku xidhka ayaa ah boos-is-dhex-dhexaad ah oo loogu talagalay gudbinta warbaahinta gaarka ah, sida fiilada fiber-optic ama fiilada naxaasta.[1] Faa'iidada isticmaalka SFP-yada marka la barbar dhigo is-dhexgalka go'an (tusaale isku xirayaasha moodeelka ah ee furayaasha Ethernet) waa in dekedaha gaarka loo leeyahay lagu qalabayn karo noocyo kala duwan oo transceivers sida loogu baahan yahay, iyadoo inta badan ay ku jiraan terminaalka khadka indhaha, kaararka shabakada, furayaasha iyo router.

QSFP, oo u taagan Quad Small Form-Factor Pluggable,waanooc ka mid ah moduleka transceiver loo isticmaalo gudbinta xogta xawaaraha sare ee aaladaha isku xidhka, gaar ahaan xarumaha xogta iyo jawiga xisaabinta waxqabadka sare. Waxaa loo qaabeeyey inay taageerto kanaalo badan (sida caadiga ah afar) waxayna xamili kartaa xogta u dhaxaysa 10 Gbps ilaa 400 Gbps, iyadoo ku xidhan nooca cutubka gaarka ah.

Kobcinta QSFP:

Halbeegga QSFP waxa uu kobcay wakhti ka dib, oo leh noocyo cusub sida QSFP+, QSFP28, QSFP56, iyo QSFP-DD (Dansity Double) oo bixinaya heerka xogta iyo awoodaha. Noocyadan cusub waxay ku dhismaan naqshadda asalka ah ee QSFP si ay u daboolaan baahida sii kordheysa ee xawaaraha xawaaraha sare iyo xawaaraha degdegga ah ee shabakadaha casriga ah.

Astaamaha muhiimka ah ee QSFP:

• Cufnaanta Sare:

Qaybaha QSFP waxaa loogu talagalay inay noqdaan kuwo is haysta, taasoo u oggolaanaysa tiro badan oo isku xidh ah meel bannaan oo yar.

• Ku-kulul

Waa la gelin karaa lagana saari karaa aaladda inta uu shidmayo, iyada oo aan la carqaladayn shabakadda.

• Kanaalo badan:

Qaybaha QSFP waxay sida caadiga ah leeyihiin afar kanaal, mid kastaa awood u leh inuu gudbiyo xogta, taasoo u oggolaanaysa heerka xawaaraha sare ee xawaaraha iyo xogta.

• Heerarka Xogta Kala Duwan:

Noocyo kala duwan oo QSFP ah ayaa jira, sida QSFP+, QSFP28, QSFP56, iyo QSFP-DD, kuwaas oo taageeraya xawaare kala duwan min 40Gbps ilaa 400Gbps iyo wixii ka dambeeya.

• Codsiyada kala duwan:

Qaybaha QSFP waxaa loo isticmaalaa codsiyo kala duwan, oo ay ku jiraan xarumaha xogta ee isku xidhka, xisaabinta waxqabadka sare, iyo shabakadaha isgaarsiinta.

• Copper iyo Fiber Optic Ikhtiyaarada:

Qaybaha QSFP waxaa lagu isticmaali karaa labadaba fiilooyinka naxaasta ah (Fiber optic cables ama DACs).

40 Gbit/s (QSFP+)

QSFP+ waa kobcinta QSFP si ay u taageerto afar 10 Gbit/s kanaal oo sidda 10 Gigabit Ethernet, 10GFC Fiber Channel, ama QDR InfiniBand. Kanaalka 4 ayaa sidoo kale lagu dari karaa hal 40 Gigabit Ethernet isku xirka.

50 Gbit/s (QSFP14)

Heerka QSFP14 waxaa loogu talagalay inuu qaado FDR InfiniBand, SAS-3 ama 16G Fiber Channel.

100 Gbit/s (QSFP28)

Heerka QSFP28 waxaa loogu talagalay inuu qaado 100 Gigabit Ethernet, EDR InfiniBand, ama 32G Fiber Channel. Mararka qaarkood nooca transceiver waxaa sidoo kale loo tixraacaa sida QSFP100 ama 100G QSFP si loo fududeeyo.

200 Gbit/s (QSFP56)

QSFP56 waxaa loogu talagalay inay qaado 200 Gigabit Ethernet, HDR InfiniBand, ama 64G Fiber Channel. Kobcinta ugu weyn ayaa ah in QSFP56 ay isticmaasho afar-heer garaaca garaaca-amplitude modulation (PAM-4) halkii aan dib loogu noqon-eber (NRZ). Waxay isticmaashaa tilmaamo jireed la mid ah sida QSFP28 (SFF-8665), oo leh tilmaamo koronto oo ka yimid SFF-8024 iyo dib u eegista 2.10a ee SFF-8636. Mararka qaarkood nooca transceiver noocan ah waxaa loo tixraacaa 200G QSFP si loo fududeeyo.

KCO Fiber wuxuu bixiyaa tayada sare ee moduleka fiber optic SFP, SFP+, XFP, SFP28, QSFP, QSFP+, QSFP28. QSFP56, QSFP112, AOC, iyo DAC, kuwaas oo la jaan qaadi kara inta badan noocyada beddelka sida Cisco, Huawei, H3C, ZTE, Juniper, Arista, HP, iwm. Fadlan la xiriir kooxdayada iibka si aad u hesho taageerada ugu fiican ee ku saabsan arrinta farsamada iyo sidoo kale qiimaha.
