Kuyini i-QSFP?

I-Small Form-factor Pluggable (SFP)iyifomethi yemojuli yesixhumi senethiwekhi esihlanganisiwe, esixhumeka kalula esisetshenziselwa kokubili izinhlelo zokusebenza zokuxhumana ngocingo kanye nokuxhumana kwedatha. Isixhumi se-SFP kuhadiwe yokuxhumana siyisikhala semojuli se-transceiver ethile yemidiya, njengekhebula le-fiber-optic noma ikhebula lethusi.[1] Inzuzo yokusebenzisa ama-SFP uma kuqhathaniswa nezixhumi ezihleliwe (isb. izixhumi zemojuli kuma-switch e-Ethernet) ukuthi amachweba ngamanye angafakelwa izinhlobo ezahlukene zama-transceiver njengoba kudingeka, iningi lawo lifaka phakathi ama-terminals e-optical line, amakhadi enethiwekhi, amaswishi nama-routers.

I-QSFP, emele i-Quad Small Form-factor Pluggable,kuyintouhlobo lwemodyuli ye-transceiver esetshenziselwa ukudlulisa idatha ngesivinini esikhulu kumadivayisi okuxhumana, ikakhulukazi ezikhungweni zedatha nasezindaweni zekhompyutha ezisebenzayo kakhulu. Yenzelwe ukusekela iziteshi eziningi (ngokuvamile ezine) futhi ingaphatha amazinga edatha asukela ku-10 Gbps kuya ku-400 Gbps, kuye ngohlobo oluthile lwemodyuli.

Ukuvela kwe-QSFP:

Izinga le-QSFP liye lathuthuka ngokuhamba kwesikhathi, ngezinguqulo ezintsha ezifana ne-QSFP+, QSFP28, QSFP56, kanye ne-QSFP-DD (Double Density) ezinikeza amazinga edatha akhuphukile kanye namakhono. Lezi zinguqulo ezintsha zakhela phezu komklamo wokuqala we-QSFP ukuze kuhlangatshezwane nezidingo ezikhulayo ze-bandwidth ephezulu kanye nesivinini esisheshayo kumanethiwekhi anamuhla.

Izici Eziyinhloko ze-QSFP:

• Ubuningi Obuphezulu:

Amamojula e-QSFP aklanyelwe ukuba abe mancane, okuvumela inani elikhulu lokuxhumeka endaweni encane kakhulu.

• Okushisayo Okungaxhunywa:

Zingafakwa futhi zikhishwe kudivayisi ngenkathi ivuliwe, ngaphandle kokubangela ukuphazamiseka kunethiwekhi.

• Iziteshi Eziningi:

Amamojula e-QSFP ngokuvamile aneziteshi ezine, ngayinye ekwazi ukudlulisa idatha, okuvumela amazinga aphezulu e-bandwidth kanye nedatha.

• Amanani Edatha Ahlukahlukene:

Kunezinhlobo ezahlukene ze-QSFP, njenge-QSFP+, QSFP28, QSFP56, kanye ne-QSFP-DD, ezisekela isivinini esihlukile kusukela ku-40Gbps kuya ku-400Gbps nangaphezulu.

• Izicelo Ezihlukahlukene:

Amamojula e-QSFP asetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza, kufaka phakathi ukuxhumana kwesikhungo sedatha, ukubalwa kwekhompyutha okusebenzayo okuphezulu, kanye namanethiwekhi okuxhumana ngocingo.

• Izinketho ze-Copper kanye ne-Fiber Optic:

Amamojula e-QSFP angasetshenziswa kokubili ngezintambo zethusi (Amakhebula Anamathiselwe Ngokuqondile noma ama-DAC) kanye nezintambo ze-fiber optic.

40 Gbit/s (QSFP+)

I-QSFP+ iwukuvela kwe-QSFP ukusekela iziteshi ezine ze-10 Gbit/s ezithwala i-10 Gigabit Ethernet, i-10GFC Fiber Channel, noma i-QDR InfiniBand. Iziteshi ezine zingahlanganiswa futhi zibe yisixhumanisi esisodwa se-40 Gigabit Ethernet.

50 Gbit/s (QSFP14)

Izinga le-QSFP14 lenzelwe ukuthwala i-FDR InfiniBand, i-SAS-3 noma i-16G Fiber Channel.

100 Gbit/s (QSFP28)

Izinga le-QSFP28 lenzelwe ukuthwala i-100 Gigabit Ethernet, i-EDR InfiniBand, noma i-32G Fiber Channel. Ngezinye izikhathi lolu hlobo lwe-transceiver lubizwa nangokuthi i-QSFP100 noma i-100G QSFP ukuze kube lula.

200 Gbit/s (QSFP56)

I-QSFP56 yakhelwe ukuthwala i-200 Gigabit Ethernet, i-HDR InfiniBand, noma i-64G Fiber Channel. Ukuthuthukiswa okukhulu ukuthi i-QSFP56 isebenzisa i-four-level pulse-amplitude modulation (PAM-4) esikhundleni se-non-return-to-zero (NRZ). Isebenzisa i-physical specifications efanayo ne-QSFP28 (SFF-8665), ene-electric specifications evela ku-SFF-8024 kanye ne-revision 2.10a ye-SFF-8636. Ngezinye izikhathi lolu hlobo lwe-transceiver lubizwa ngokuthi i-200G QSFP ukuze kube lula.

I-KCO Fiber inikeza ikhwalithi ephezulu ye-fiber optic module SFP, SFP+, XFP, SFP28, QSFP, QSFP+, QSFP28. QSFP56, QSFP112, AOC, kanye ne-DAC, ezingahambisana nezinhlobo eziningi zeswishi ezifana neCisco, Huawei, H3C, ZTE, Juniper, Arista, HP, …njll. Sicela uxhumane nethimba lethu lokuthengisa ukuze uthole ukwesekwa okungcono kakhulu mayelana nenkinga yezobuchwepheshe kanye nentengo.
