I-SFP
I-SFP ingaqondwa njengenguqulo ethuthukisiwe ye-GBIC. Umthamo wayo uyi-1/2 kuphela yaleyo ye-GBIC module, okwandisa kakhulu ubuningi be-port yamadivayisi enethiwekhi. Ngaphezu kwalokho, amazinga okudluliswa kwedatha e-SFP asukela ku-100Mbps kuya ku-4Gbps.
I-SFP+
I-SFP+ inguqulo ethuthukisiwe ye-SFP esekela isiteshi sefayibha esingu-8Gbit/s, i-10G Ethernet kanye ne-OTU2, okuyizinga lenethiwekhi yokudlulisa optical. Ngaphezu kwalokho, izintambo eziqondile ze-SFP+ (okungukuthi, izintambo zesivinini esiphezulu ze-SFP+ DAC kanye nezintambo ze-optical ezisebenzayo ze-AOC) zingaxhumanisa amachweba amabili e-SFP+ ngaphandle kokwengeza amamojula engeziwe e-optical kanye nezintambo (izintambo zenethiwekhi noma ama-fiber jumpers), okuyisinqumo esihle sokuxhuma ngqo phakathi kokushintshana kwenethiwekhi okufushane okubili okuseduze.
I-SFP28
I-SFP28 inguqulo ethuthukisiwe ye-SFP+, enobukhulu obufana ne-SFP+ kodwa ingasekela isivinini sesiteshi esisodwa esingu-25Gb/s. I-SFP28 inikeza ikhambi eliphumelelayo lokuthuthukisa amanethiwekhi e-10G-25G-100G ukuze kuhlangatshezwane nezidingo ezikhulayo zamanethiwekhi esikhungo sedatha sesizukulwane esilandelayo.
I-QSFP+
I-QSFP+ inguqulo ebuyekeziwe ye-QSFP. Ngokungafani ne-QSFP+, esekela iziteshi ezingu-4 gbit /s ngesilinganiso esingu-1Gbit / s, i-QSFP + isekela iziteshi ezingu-4 x 10Gbit / s ngesilinganiso esingu-40Gbps. Uma kuqhathaniswa ne-SFP+, izinga lokudlulisa le-QSFP + liphakeme ngokuphindwe kane kunele-SFP+. I-QSFP + ingasetshenziswa ngqo lapho kusetshenziswa inethiwekhi engu-40G, ngaleyo ndlela kongiwe izindleko futhi kwandiswe ubuningi be-port.
QSFP28
I-QSFP28 inikeza iziteshi ezine zesignali ezishintshashintshayo ezinesivinini esikhulu. Izinga lokudlulisa lesiteshi ngasinye liyahlukahluka kusuka ku-25Gbps kuya ku-40Gbps, okungahlangabezana nezidingo ze-100 gbit/s Ethernet (4 x 25Gbps) kanye nezinhlelo zokusebenza ze-EDR InfiniBand. Kunezinhlobo eziningi zemikhiqizo ye-QSFP28, futhi kusetshenziswa izindlela ezahlukene zokudlulisa i-100 Gbit/s, njengokuxhumeka okuqondile kwe-100 Gbit/s, ukuguqulwa kwe-100 Gbit/s kube izixhumanisi ezine zegatsha ze-25 Gbit/s, noma ukuguqulwa kwe-100 Gbit/s kube izixhumanisi ezimbili zegatsha ze-50 Gbit/s.
Umehluko kanye nokufana kwe-SFP, SFP+, SFP28, QSFP+, QSFP28
Ngemva kokuqonda ukuthi ziyini i-SFP, i-SFP+, i-SFP28, i-QSFP+, i-QSFP28, ukufana kanye nomehluko phakathi kwalezi zinto ezimbili kuzokwethulwa ngokulandelayo.
OkunconyiweUmthengisi Wephakethe Lenethiwekhiukusekela i-100G, 40G kanye ne-25G, ukuvakashelalapha
OkunconyiweUkuthepha KwenethiwekhiUkusekela i-10G, i-1G kanye ne-Bypass ehlakaniphile, ukuvakashelalapha
I-SFP ne-SFP+: Usayizi ofanayo, amazinga ahlukene kanye nokuhambisana
Usayizi kanye nokubonakala kwamamojula e-SFP kanye ne-SFP+ kuyafana, ngakho abakhiqizi bamadivayisi bangasebenzisa ukwakheka okubonakalayo kwe-SFP kumaswishi anamachweba e-SFP+. Ngenxa yobukhulu obufanayo, amakhasimende amaningi asebenzisa amamojula e-SFP kumachweba e-SFP+ amaswishi. Lo msebenzi uyenzeka, kodwa izinga lehliswa libe yi-1Gbit/s. Ngaphezu kwalokho, ungasebenzisi imojula ye-SFP+ kusikhala se-SFP. Ngaphandle kwalokho, ichweba noma imojula ingase yonakale. Ngaphezu kokuhambisana, i-SFP kanye ne-SFP+ zinamazinga okudlulisa ahlukene kanye namazinga. I-SFP+ ingadlulisela ubuningi obungu-4Gbit/s kanye nobukhulu obungu-10Gbit/s. I-SFP isekelwe kuphrothokholi ye-SFF-8472 kuyilapho i-SFP+ isekelwe kuphrothokholi ye-SFF-8431 kanye ne-SFF-8432.
I-SFP28 kanye ne-SFP+: Imojula ye-optical ye-SFP28 ingaxhunywa echwebeni le-SFP+
Njengoba kushiwo ngenhla, i-SFP28 inguqulo ethuthukisiwe ye-SFP+ enobukhulu obufanayo kodwa amazinga okudlulisa ahlukene. Izinga lokudlulisa le-SFP+ lingu-10Gbit/s kanti ele-SFP28 lingu-25Gbit/s. Uma i-module ye-optical ye-SFP+ ifakwa echwebeni le-SFP28, izinga lokudlulisa isixhumanisi lingu-10Gbit/s, futhi okuphambene nalokho. Ngaphezu kwalokho, ikhebula lethusi elixhunywe ngqo le-SFP28 linomkhawulokudonsa ophezulu kanye nokulahlekelwa okuphansi kunekhebula lethusi elixhunywe ngqo le-SFP+.
I-SFP28 kanye ne-QSFP28: amazinga ephrothokholi ahlukile
Nakuba zombili i-SFP28 ne-QSFP28 zinenombolo ethi "28", zombili izinhlobo zihlukile kunqubo ejwayelekile. I-SFP28 isekela isiteshi esisodwa esingu-25Gbit/s, kanti i-QSFP28 isekela iziteshi ezine ezingu-25Gbit/s. Zombili zingasetshenziswa kumanethiwekhi angu-100G, kodwa ngezindlela ezahlukene. I-QSFP28 ingafinyelela ukudluliselwa kwe-100G ngezindlela ezintathu ezishiwo ngenhla, kodwa i-SFP28 ithembele kumakhebula esivinini esiphezulu egatsha le-QSFP28 kuya ku-SFP28. Isithombe esilandelayo sibonisa 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 anobukhulu obufanayo futhi aneziteshi ezine ezihlanganisiwe zokudlulisa nokwamukela. Ngaphezu kwalokho, imindeni yomibili ye-QSFP+ kanye ne-QSFP28 inamamojula we-optical kanye nezintambo ze-DAC/AOC ezinesivinini esikhulu, kodwa ngamanani ahlukene. Imojula ye-QSFP+ isekela izinga lesiteshi esisodwa esingu-40Gbit/s, kanti i-QSFP+ DAC/AOC isekela izinga lokudlulisa elingu-4 x 10Gbit/s. Imojula ye-QSFP28 idlulisela idatha ngesilinganiso esingu-100Gbit/s. I-QSFP28 DAC/AOC isekela u-4 x 25Gbit/s noma u-2 x 50Gbit/s. Qaphela ukuthi imojula ye-QSFP28 ayikwazi ukusetshenziselwa izixhumanisi zegatsha le-10G. Kodwa-ke, uma inkinobho enamachweba e-QSFP28 isekela amamojula e-QSFP+, ungafaka amamojula e-QSFP+ kumachweba e-QSFP28 ukuze usebenzise izixhumanisi zegatsha ezingu-4 x 10G.
