Yintoni i-QSFP?

IFomu encinci iPluggable (SFP)yifomathi yemodyuli yojongano lwenethiwekhi edibeneyo, eshushu-pluggable esetyenziswa kuzo zombini unxibelelwano kunye nedatha yonxibelelwano. Ujongano lwe-SFP kwihardware yothungelwano yimodyuli yokubeka i-transceiver yemidiya ethile, efana nentambo yefiber-optic okanye intambo yobhedu.[1] Inzuzo yokusebenzisa ii-SFPs xa kuthelekiswa nojongano olusisigxina (umzekelo, izihlanganisi zemodyuli kwiiswitshi ze-Ethernet) kukuba izibuko zomntu ngamnye zinokuxhotyiswa ngeentlobo ezahlukeneyo zee-transceivers njengoko zifunwa, uninzi lubandakanya iitheminali zomgca we-optical, amakhadi womnatha, iiswitshi kunye neerotha.

I-QSFP, emele i-Quad Small-Factor-Factor Pluggable,yiuhlobo lwemodyuli ye-transceiver esetyenziselwa ukuhanjiswa kwedatha yesantya esiphezulu kwizixhobo zokunxibelelana, ngakumbi kumaziko edatha kunye neendawo eziphezulu zokusebenza zekhompyuter. Yenzelwe ukuxhasa iziteshi ezininzi (ngokuqhelekileyo ezine) kwaye inokusingatha amazinga edatha ukusuka kwi-10 Gbps ukuya kwi-400 Gbps, kuxhomekeke kuhlobo oluthile lwemodyuli.

Ukuzivelela kweQSFP:

Umgangatho we-QSFP uguquke ngokuhamba kwexesha, kunye neenguqulelo ezintsha ezifana ne-QSFP +, i-QSFP28, i-QSFP56, kunye ne-QSFP-DD (i-Double Density) enikezela amaxabiso edatha kunye nobuchule. Ezi nguqulelo zintsha zakha phezu koyilo lweQSFP lwantlandlolo ukuhlangabezana neemfuno ezikhulayo ze-bandwidth ephezulu kunye nezantya ezikhawulezayo kuthungelwano lwangoku.

Iimpawu eziphambili ze-QSFP:

• Ukuxinana okuphezulu:

Iimodyuli ze-QSFP zenzelwe ukuba zidibanise, zivumela inani eliphezulu lokudibanisa kwindawo encinci.

• I-Hot-plugable:

Zinokufakwa kwaye zisuswe kwisixhobo ngelixa sisasebenza, ngaphandle kokubangela ukuphazamiseka kwinethiwekhi.

• Amatshaneli amaninzi:

Iimodyuli ze-QSFP ngokuqhelekileyo zineziteshi ezine, nganye iyakwazi ukudlulisa idatha, ivumela i-bandwidth ephezulu kunye namazinga edatha.

• Amaxabiso eDatha awahlukeneyo:

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

• Ii-Aplikeshini eziNyezo:

Iimodyuli ze-QSFP zisetyenziselwa uluhlu olubanzi lwezicelo, kubandakanywa i-data center interconnects, i-high-performance computing, kunye ne-telecommunications networks.

• Iinketho zoKhopolo kunye neFayibha:

Iimodyuli ze-QSFP zingasetyenziswa kunye neentambo zombini zobhedu (Iintambo zokuQinisekisa ngokuthe ngqo okanye ii-DACs) kunye neentambo zefiber optic.

40 Gbit/s (QSFP+)

I-QSFP + yi-evolution ye-QSFP ukuxhasa iziteshi ezine ze-10 Gbit / s ezithwala i-10 Gigabit Ethernet, i-10GFC yeFiber Channel, okanye i-QDR InfiniBand. Iziteshi ezi-4 nazo zinokudibaniswa kwikhonkco elilodwa le-40 Gigabit Ethernet.

50 Gbit/s (QSFP14)

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

100 Gbit/s (QSFP28)

Umgangatho we-QSFP28 wenzelwe ukuthwala i-100 Gigabit Ethernet, i-EDR InfiniBand, okanye i-32G yeFiber Channel. Ngamanye amaxesha olu hlobo lwe-transceiver lukwabizwa 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 yeFiber Channel. Uphuculo olukhulu kukuba i-QSFP56 isebenzisa i-modulation ye-pulse-amplitude yezinga elinesine (PAM-4) endaweni yokungabuyi-zero (NRZ). Isebenzisa iinkcukacha zomzimba ezifanayo njenge-QSFP28 (SFF-8665), kunye neenkcukacha zombane ezivela kwi-SFF-8024 kunye nokuhlaziywa kwe-2.10a ye-SFF-8636. Ngamanye amaxesha olu hlobo lwe-transceiver lubizwa ngokuba yi-200G QSFP ngenxa yokulula.
