Iyini i-QSFP?

I-Small Form-factor Pluggable (SFP)iyifomethi yemojula yenethiwekhi ehlangene, exhumeke kuxhumeke kuxhumeke kuyo esetshenziswa kukho kokubili izinhlelo zokusebenza zokuxhumana ngocingo nedatha. Isixhumi esibonakalayo se-SFP kuzingxenyekazi zekhompuyutha zenethiwekhi iyisikhala semojuli yesidluliseli esiqondiswe kumidiya, njengekhebula le-fiber-optic noma intambo yethusi.[1] Inzuzo yokusebenzisa ama-SFP uma kuqhathaniswa nezindawo zokusebenzelana ezingaguquki (isb. izixhumi eziyimojuli kumaswishi e-Ethernet) ukuthi izimbobo ngazinye zingahlonyiswa ngezinhlobo ezahlukene zama-transceiver njengoba kudingekile, iningi lihlanganisa amatheminali olayini obonakalayo, amakhadi enethiwekhi, amaswishi namarutha.

I-QSFP, emele i-Quad Small Form-factor Pluggable,kuyintouhlobo lwemojuli ye-transceiver esetshenziselwa ukudluliswa kwedatha ngesivinini esiphezulu kumadivayisi enethiwekhi, ikakhulukazi ezikhungweni zedatha nasezindaweni zekhompyutha ezisebenza kahle kakhulu.. Iklanyelwe ukusekela iziteshi eziningi (ngokujwayelekile ezine) futhi ingaphatha amanani edatha asuka ku-10 Gbps kuya ku-400 Gbps, kuye ngohlobo lwemojuli ethile.

Ukuvela kwe-QSFP:

Izinga le-QSFP liye lashintsha ngokuhamba kwesikhathi, ngezinguqulo ezintsha ezifana ne-QSFP+, QSFP28, QSFP56, ne-QSFP-DD (Double Density) ezinikeza amanani anyukile wedatha namandla. Lezi zinguqulo ezintsha zakhela phezu kwedizayini yasekuqaleni ye-QSFP ukuze ihlangabezane nezidingo ezikhulayo zomkhawulokudonsa ophezulu kanye nesivinini esisheshayo kumanethiwekhi esimanje.

Izici ezibalulekile ze-QSFP:

• Ukuminyana Okuphezulu:

Amamojula e-QSFP enzelwe ukuthi ahlangane, avumele inombolo ephezulu yokuxhumana endaweni encane.

• Okushisayo kuyaxhumeka:

Angafakwa futhi akhishwe kudivayisi ngenkathi ivuliwe, ngaphandle kokubangela ukuphazamiseka kunethiwekhi.

• Iziteshi Eziningi:

Amamojula e-QSFP ngokuvamile aneziteshi ezine, ngayinye ekwazi ukudlulisa idatha, okuvumela umkhawulokudonsa ophezulu namazinga edatha.

• Amanani Edatha Ahlukahlukene:

Kukhona okuhlukile kwe-QSFP, okufana ne-QSFP+, QSFP28, QSFP56, ne-QSFP-DD, esekela izivinini ezihlukene ukusuka ku-40Gbps ukuya ku-400Gbps nangaphezulu.

• Izinhlelo Ezihlukahlukene:

Amamojula e-QSFP asetshenziswa ezinhlelweni eziningi ezahlukene, okuhlanganisa ukuxhumana kwesikhungo sedatha, ukusebenza kahle kwekhompyutha kwamakhompyutha, namanethiwekhi ezokuxhumana.

• Izinketho ze-Copper ne-Fiber Optic:

Amamojula e-QSFP angasetshenziswa ngazo zombili izintambo zethusi (AmaCable Anamathisele Okuqondile 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, 10GFC Fiber Channel, noma i-QDR InfiniBand. Iziteshi ezi-4 nazo zingahlanganiswa zibe isixhumanisi 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, EDR InfiniBand, noma i-32G Fiber Channel. Kwesinye isikhathi lolu hlobo lwe-transceiver luphinde lubizwe ngokuthi yi-QSFP100 noma i-100G QSFP ukuze kube lula.

200 Gbit/s (QSFP56)

I-QSFP56 yakhelwe ukuthwala i-200 Gigabit Ethernet, HDR InfiniBand, noma i-64G Fiber Channel. Ukuthuthukiswa okukhulu ukuthi i-QSFP56 isebenzisa i-modulation ye-pulse-amplitude yamazinga amane (PAM-4) esikhundleni sokungabuyi ku-zero (NRZ). Isebenzisa ukucaciswa komzimba okufanayo njenge-QSFP28 (SFF-8665), enemininingwane kagesi evela ku-SFF-8024 kanye nokubuyekeza okungu-2.10a kwe-SFF-8636. Kwesinye isikhathi lolu hlobo lwe-transceiver lubizwa nge-200G QSFP ngenxa yokwenza lula.

I-KCO Fiber inikeza ikhwalithi ephezulu ye-fiber optic module SFP, SFP+, XFP, SFP28, QSFP, QSFP+, QSFP28. I-QSFP56, QSFP112, AOC, ne-DAC, engasebenzisana neningi lamaswishi afana neCisco, Huawei, H3C, ZTE, Juniper, Arista, HP, ... njll. Sicela uxhumane nethimba lethu labadayisi ukuze uthole ukwesekwa okungcono kakhulu mayelana nenkinga yezobuchwepheshe kanye nentengo.
