I-SFP
I-SFP ingaqondwa njengenguqulo ethuthukisiwe ye-GBIC. Ivolumu yayo iyi-1/2 kuphela yaleyo yemojula ye-GBIC, okwandisa kakhulu ukuminyana kwechweba lamadivayisi enethiwekhi. Ngaphezu kwalokho, amazinga okudluliswa kwedatha e-SFP asukela ku-100Mbps kuya ku-4Gbps.
I-SFP+
I-SFP+ inguqulo ethuthukisiwe ye-SFP esekela i-fiber channel ye-8Gbit/s, i-10G Ethernet ne-OTU2, izinga lenethiwekhi yokudlulisa amehlo. Ngaphezu kwalokho, izintambo eziqondile ze-SFP + (okungukuthi, izintambo ze-SFP+ DAC ezinesivinini esikhulu kanye nezintambo ezibonakalayo ze-AOC ezisebenzayo) zingaxhuma amachweba amabili e-SFP + ngaphandle kokwengeza amamojula optical engeziwe nezintambo (izintambo zenethiwekhi noma ama-fiber jumpers), okuyisinqumo esihle sokuxhumana okuqondile phakathi amaswishi amabili enethiwekhi amabanga amafushane asondelene.
SFP28
I-SFP28 inguqulo ethuthukisiwe ye-SFP+, enosayizi ofanayo ne-SFP+ kodwa ekwazi ukusekela isivinini sesiteshi esisodwa esingu-25Gb/s. I-SFP28 inikeza isisombululo esisebenzayo sokuthuthukisa amanethiwekhi we-10G-25G-100G ukuze ahlangabezane nezidingo ezikhulayo zamanethiwekhi esikhungo sedatha yesizukulwane esilandelayo.
I-QSFP+
I-QSFP+ inguqulo ebuyekeziwe ye-QSFP. Ngokungafani ne-QSFP+, esekela iziteshi ze-4 gbit / s ngesilinganiso se-1Gbit/s, i-QSFP+ isekela iziteshi ezingu-4 x 10Gbit/s ngenani le-40Gbps. Uma kuqhathaniswa ne-SFP+, izinga lokudlulisela le-QSFP+ liphakeme ngokuphindwe kane kune-SFP+. I-QSFP+ ingasetshenziswa ngokuqondile lapho inethiwekhi ye-40G isetshenziswa, ngaleyo ndlela yonga izindleko nokwandisa ukuminyana kwembobo.
QSFP28
I-QSFP28 inikeza iziteshi ezine zesignali ezinesivinini esiphezulu. Izinga lokudlulisela lesiteshi ngasinye liyahlukahluka ukusuka ku-25Gbps kuya ku-40Gbps, elingahlangabezana nezimfuneko ze-100 gbit/s Ethernet (4 x 25Gbps) kanye nezinhlelo zokusebenza ze-EDR InfiniBand. Kunezinhlobo eziningi zemikhiqizo ye-QSFP28, futhi kusetshenziswa izindlela ezihlukene zokudluliswa kwe-100 Gbit/s, njengokuxhunywa okuqondile kwe-100 Gbit/s, ukuguqulwa kwe-100 Gbit/s kuya kuzixhumanisi ezine zamagatsha angu-25 Gbit/s, noma ukuguqulwa kwe-100 Gbit/s ku- izixhumanisi ezimbili zegatsha ezingama-50 Gbit/s.
Umehluko nokufana kwe-SFP, SFP+, SFP28, QSFP+, QSFP28
Ngemuva kokuqonda ukuthi yiziphi i-SFP, SFP +, SFP28, QSFP +, QSFP28, ukufana okuqondile nokuhlukana phakathi kokubili kuzokwethulwa ngokulandelayo.

I-SFP ne-SFP+: Usayizi ofanayo, amanani ahlukene nokuhambisana
Usayizi nokubukeka kwamamojula e-SFP ne-SFP+ kuyafana, ngakho abakhiqizi bedivayisi bangakwazi ukusebenzisa ukwakheka komzimba kwe-SFP kumaswishi anezimbobo ze-SFP+. Ngenxa yosayizi ofanayo, amakhasimende amaningi asebenzisa amamojula e-SFP kumachweba we-SFP+ wokushintsha. Lokhu kusebenza kuyenzeka, kodwa izinga lehliselwe ku-1Gbit/s. Ngaphezu kwalokho, ungasebenzisi imojula ye-SFP+ ku-slot ye-SFP. Uma kungenjalo, imbobo noma imojuli ingase yonakale. Ngaphezu kokuhambisana, i-SFP ne-SFP+ zinamazinga ahlukene okudlulisela kanye namazinga. I-SFP+ ingadlulisela ubukhulu obungu-4Gbit/s kanye nobukhulu obungu-10Gbit/s. I-SFP isuselwe kuphrothokholi ye-SFF-8472 kuyilapho i-SFP+ isekelwe kuzivumelwano ze-SFF-8431 kanye ne-SFF-8432.
I-SFP28 ne-SFP+: Imojula ye-SFP28 ye-optical ingaxhunywa ethekwini le-SFP+
Njengoba kushiwo ngenhla, i-SFP28 inguqulo ethuthukisiwe ye-SFP+ enosayizi ofanayo kodwa amazinga okudlulisela ahlukene. Izinga lokudlulisela le-SFP+ ngu-10Gbit/s kanti lelo le-SFP28 lingu-25Gbit/s. Uma imojula ye-SFP+ ye-optical ifakwe embobeni ye-SFP28, izinga lokudlulisela isixhumanisi ngu-10Gbit/s, futhi ngokuphambene nalokho. Ngaphezu kwalokho, ikhebula le-SFP28 elixhumeke ngokuqondile linomkhawulokudonsa ophezulu kanye nokulahlekelwa okuphansi kune-SFP + intambo yethusi exhunywe ngokuqondile.
I-SFP28 ne-QSFP28: izindinganiso zephrothokholi zihlukile
Nakuba zombili i-SFP28 ne-QSFP28 zinenombolo ethi "28", womabili amasayizi ahlukile kunendinganiso yephrothokholi. I-SFP28 isekela isiteshi esisodwa esingu-25Gbit/s, kanti i-QSFP28 isekela iziteshi ezine ze-25Gbit/s. Zombili zingasetshenziswa kumanethiwekhi we-100G, kodwa ngezindlela ezahlukene. I-QSFP28 ingakwazi ukufeza ukudluliswa kwe-100G ngokusebenzisa izindlela ezintathu ezishiwo ngenhla, kodwa i-SFP28 incike ku-QSFP28 kuya ku-SFP28 izintambo zegatsha zejubane eliphezulu. Umfanekiso olandelayo ubonisa ukuxhumana okuqondile kwe-100G QSFP28 kuya ku-4 × SFP28 DAC.
I-QSFP ne-QSFP28: Amanani ahlukene, izinhlelo zokusebenza ezahlukene
Amamojula we-QSFP+ kanye ne-QSFP28 optical anosayizi ofanayo futhi aneziteshi ezine ezididiyelwe zokudlulisa nokwamukela. Ngaphezu kwalokho, yomibili imindeni ye-QSFP + ne-QSFP28 inamamojula optical kanye nezintambo ze-DAC/AOC zesivinini esikhulu, kodwa ngamanani ahlukene. Imojuli ye-QSFP + isekela izinga lesiteshi esisodwa esingu-40Gbit/s, futhi i-QSFP+ DAC/AOC isekela izinga lokudlulisela le-4 x 10Gbit/s. Imojula ye-QSFP28 idlulisela idatha ngenani le-100Gbit/s. I-QSFP28 DAC/AOC isekela i-4 x 25Gbit/s noma i-2 x 50Gbit/s. Qaphela ukuthi imojuli ye-QSFP28 ayikwazi ukusetshenziselwa izixhumanisi zegatsha le-10G. Nokho, uma ukushintsha okunamachweba we-QSFP28 kusekela amamojula e-QSFP+, ungafaka amamojula e-QSFP+ kumachweba we-QSFP28 ukuze usebenzise izixhumanisi zegatsha ezingu-4 x 10G.
