Yintoni i-QSFP?

I-Small Form-Factor Pluggable (SFP)yifomathi yemodyuli yenethiwekhi encinci, ekwaziyo ukuxhunywa eshushu esetyenziselwa zombini usetyenziso lonxibelelwano kunye nonxibelelwano lwedatha. I-SFP interface kwi-hardware yenethiwekhi yindawo yemodyuli ye-transceiver ethile yemidiya, njengentambo ye-fiber-optic okanye intambo yekopolo.[1] Inzuzo yokusebenzisa ii-SFP xa kuthelekiswa ne-fixed interfaces (umz. izihlanganisi ze-modular kwi-Ethernet switches) kukuba ii-ports ngazinye zinokuxhotyiswa ngeentlobo ezahlukeneyo ze-transceivers njengoko kufuneka, uninzi lwazo luquka ii-terminals ze-optical line, amakhadi enethiwekhi, ii-switches kunye nee-routers.

I-QSFP, emele iQuad Small Form-factor Pluggable,yiuhlobo lwemodyuli ye-transceiver esetyenziselwa ukuhanjiswa kwedatha ngesantya esiphezulu kwizixhobo zothungelwano, ngakumbi kumaziko edatha nakwiindawo zekhompyutha ezisebenzayo kakhuluYenzelwe ukuxhasa iitshaneli ezininzi (ngesiqhelo ezine) kwaye inokusingatha amazinga edatha ukusuka kwi-10 Gbps ukuya kwi-400 Gbps, kuxhomekeke kuhlobo oluthile lwemodyuli.

Uphuhliso lwe-QSFP:

Umgangatho we-QSFP uye waguquka ngokuhamba kwexesha, kunye neenguqulelo ezintsha ezifana ne-QSFP+, QSFP28, QSFP56, kunye ne-QSFP-DD (Double Density) ezibonelela ngamazinga edatha anyukileyo kunye nobuchule. Ezi nguqulelo zintsha zakhela phezu koyilo lwe-QSFP lwantlandlolo ukuhlangabezana neemfuno ezikhulayo ze-bandwidth ephezulu kunye nesantya esikhawulezayo kwiinethiwekhi zanamhlanje.

Iimpawu eziphambili ze-QSFP:

• Uxinano Oluphezulu:

Iimodyuli ze-QSFP zenzelwe ukuba zibe ncinci, zivumela inani elikhulu lonxibelelwano kwindawo encinci.

• Ishushu-Inokutsalwa:

Zingafakwa kwaye zisuswe kwisixhobo ngelixa sivuliwe, ngaphandle kokubangela ukuphazamiseka kwinethiwekhi.

• Iitshaneli ezininzi:

Iimodyuli ze-QSFP zihlala zineendlela ezine, nganye ikwazi ukudlulisa idatha, ivumela ukuba kubekho i-bandwidth ephezulu kunye namazinga edatha.

• Amaxabiso eDatha ahlukeneyo:

Kukho iintlobo ezahlukeneyo ze-QSFP, ezifana ne-QSFP+, i-QSFP28, i-QSFP56, kunye ne-QSFP-DD, ezixhasa isantya esahlukileyo ukusuka kwi-40Gbps ukuya kwi-400Gbps nangaphezulu.

• Izicelo Ezininzi:

Iimodyuli ze-QSFP zisetyenziswa kwiintlobo ngeentlobo zezicelo, kubandakanya uqhagamshelo lweziko ledatha, ikhompyutha esebenza kakhulu, kunye neenethiwekhi zonxibelelwano.

• Iinketho zeCopper kunye neFiber Optic:

Iimodyuli ze-QSFP zingasetyenziswa zombini iintambo zobhedu (iiNtambo eziQokelelweyo okanye ii-DAC) kunye neentambo ze-fiber optic.

40 Gbit/s (QSFP+)

I-QSFP+ yindlela entsha yokuxhasa iitshaneli ezine ze-10 Gbit/s ezithwala i-10 Gigabit Ethernet, i-10GFC Fiber Channel, okanye i-QDR InfiniBand. Ezi tshaneli zine zinokudityaniswa zibe yikhonkco elinye le-40 Gigabit Ethernet.

50 Gbit/s (QSFP14)

Umgangatho we-QSFP14 wenzelwe ukuthwala i-FDR InfiniBand, i-SAS-3 okanye i-16G Fiber Channel.

100 Gbit/s (QSFP28)

Umgangatho we-QSFP28 wenzelwe ukuthwala i-100 Gigabit Ethernet, i-EDR InfiniBand, okanye i-32G Fiber Channel. Ngamanye amaxesha olu hlobo lwe-transceiver lubizwa ngokuba yi-QSFP100 okanye i-100G QSFP ngenxa yokulula.

200 Gbit/s (QSFP56)

I-QSFP56 yenzelwe ukuthwala i-200 Gigabit Ethernet, i-HDR InfiniBand, okanye i-64G Fiber Channel. Eyona nto iphucukileyo kukuba i-QSFP56 isebenzisa i-four-level pulse-amplitude modulation (PAM-4) endaweni ye-non-return-to-zero (NRZ). Isebenzisa i-physical specifications efanayo ne-QSFP28 (SFF-8665), kunye ne-electric specifications evela kwi-SFF-8024 kunye ne-revision 2.10a ye-SFF-8636. Ngamanye amaxesha olu hlobo lwe-transceiver lubizwa ngokuba yi-200G QSFP ngenxa yokulula.

I-KCO Fiber ibonelela nge-fiber optic module esemgangathweni ophezulu ye-SFP, SFP+, XFP, SFP28, QSFP, QSFP+, QSFP28. QSFP56, QSFP112, AOC, kunye ne-DAC, ezinokuhambelana neentlobo ezininzi zeswitshi ezifana neCisco, Huawei, H3C, ZTE, Juniper, Arista, HP, ... njl.
