I-SFP
I-SFP ingaqondakala njengenguqulo ethuthukisiwe ye-GBIC. IVolumu yayo ingu-1/2 kuphela walokho kwemodyuli ye-GBIC, eyandisa kakhulu ubuningi be-port yamadivayisi wenethiwekhi. Ngaphezu kwalokho, amanani e-SFP wokudlulisa idatha aqala kusuka ku-100mbps kuya ku-4GBPS.
I-SFP +
I-SFP + iyinguqulo ethuthukisiwe ye-SFP exhasa isiteshi se-8GBIT / S Fiberte, 10g Ethernet kanye ne-OTU2, I-Optical Transmemer Network Internet Standard. Ngaphezu kwalokho, ama-SFP + amakhebuli aqondile (ie, amakhebuli aphezulu we-SFP + DAC
SFP28
I-SFP28 inguqulo ethuthukisiwe ye-SFP +, enobukhulu obufanayo ne-SFP + kepha ingasekela isivinini sesiteshi esisodwa se-25GB / S. I-SFP28 ihlinzeka ngesisombululo esisebenzayo sokuthuthukisa amanethiwekhi we-10G-25G-100G ukuze ahlangabezane nezidingo ezikhulayo zamanethiwekhi wesikhungo esilandelayo sedatha.
QSFP +
I-QSFP + yinguqulo ebuyekeziwe ye-QSFP. Ngokungafani ne-QSFP +, esekela iziteshi ezi-4 ze-Gbit / s ngesilinganiso se-1Gbit / s, i-QSFP + isekela iziteshi ezi-4 x 10Gbit / s ngesilinganiso se-40GBPS. Uma kuqhathaniswa ne-SFP +, izinga lokudlulisa le-QSFP + liphakeme kane kunaleso le-SFP +. I-QSFP + ingasetshenziswa ngqo lapho inethiwekhi ye-40G ihanjiswa, ngaleyo ndlela ilondoloze izindleko nokwanda kwe-port density.
QSFP28
I-QSFP28 ihlinzeka ngeziteshi ezine ezihlukile zesiginali ephakeme. Izinga lokudlulisela lesiteshi ngasinye liyahlukahluka kusuka ku-25GBPS kuya ku-40GBPS, okungahlangabezana nezidingo ze-100 gbitnet / ama-4 x 25GBPS) kanye ne-EDR Infiniband Izicelo. Kunezinhlobo eziningi zemikhiqizo ye-QSFP28, kanye nezindlela ezihlukile zokudluliselwa kwe-gbit / s okungu-100 gbit / s okuqondile, ukuguqulwa kwe-gbit / i-100 gbit / s kuya kwezingu-50 / S BHARBRATCH ezenziwe ngama-50 / s.
Umehluko kanye nokufana kwe-SFP, SFP +, SFP28, QSFP +, QSFP28
Ngemuva kokuqonda ukuthi yiliphi i-SFP, SFP +, SFP28, QSFP +, QSFP28 yile, ukufana kanye nokwehluka okukhethekile phakathi kwalokhu okubili kuzokwethulwa ngokulandelayo.

I-SFP ne-SFP +: usayizi ofanayo, amanani ahlukile kanye nokuhambisana
Ubukhulu nokubukeka kwe-SFP ne-SFP + amamojula afanayo, ngakho-ke abakhiqizi bedivayisi bangamukela ukwakheka okubonakalayo kwe-SFP ekushintsheni ngama-SFP + Ports. Ngenxa yobukhulu obufanayo, amakhasimende amaningi asebenzisa amamojula we-SFP kumachweba we-SFP + wokushintsha. Lokhu kusebenza kungenzeka, kepha isilinganiso sincishisiwe ku-1GBIT / S. Ngaphezu kwalokho, ungasebenzisi imodyuli ye-SFP + ku-SFP Slot. Ngaphandle kwalokho, ichweba noma imodyuli ingalimala. Ngaphezu kokuhambisana, i-SFP ne-SFP + inamazinga namazinga ahlukene okuhambisa. I-SFP + ingadlulisela inani eliphakeme le-4Gbit / S kanye ne-10Gbit / s. I-SFP isuselwa ku-SF-8472 Protocol ngenkathi i-SFP + isuselwa kumaphrothokholi we-SF-8431 naseSF-8432.
I-SFP28 ne-SFP +: Imodyuli ye-SFP28 Optical ingaxhunywa kwi-SFP + Port
Njengoba kushiwo ngenhla, i-SFP28 yinguqulo ethuthukisiwe ye-SFP + ngosayizi ofanayo kepha amanani ahlukile wokuhambisa. Izinga lokuhambisa le-SFP + liyi-10Gbit / S kanye ne-SFP28 yi-25GBIT / S. Uma i-SFP + Optical module ifakwe ethekwini le-SFP28, izinga lokudlulisa lesixhumanisi liyi-10Gbit / s, kanye nokuphaphamela. Ngaphezu kwalokho, i-SFP28 Intambo yethusi exhunyiwe ngqo ine-bandwidth ephezulu nokulahleka okuphansi kune-SFP + ikhebula elixhunyiwe ngqo.
I-SFP28 ne-QSFP28: Amazinga we-Protocol ahlukile
Yize bobabili i-SFP28 ne-QSFP28 baphatha inombolo "28", bobabili osayizi behlukahluka kwi-protocol standard. I-SFP28 isekela isiteshi esisodwa se-25GBIT / S Single, kanye ne-QSFP28 isekela iziteshi ezine / ama-25GBITS. Zombili zingasetshenziswa kumanethiwekhi we-100G, kepha ngezindlela ezihlukile. I-QSFP28 ingafinyelela ukudluliswa kwe-100G ngezindlela ezintathu ezishiwo ngenhla, kepha i-SFP28 ithembele kwi-QSFP28 kwizintambo zegatsha le-SFP28. Lesi sibalo esilandelayo sibonisa ukuxhumana okuqondile kwe-100g QSFP28 kuya ku-4 × SFP28 DAC.
I-QSFP ne-QSFP28: Amanani ahlukile, Izicelo ezihlukile
Amamojula we-QSFP + kanye ne-QSFP28 amamojula we-optical asayizi afanayo futhi ane-admit ene-admit emine futhi athole iziteshi. Ngaphezu kwalokho, imindeni ye-QSFP + kanye ne-QSFP28 inamamojula we-Optical nama-DAC / AOC ashesha amakhethini, kepha ngamanani ahlukile. Imodyuli ye-QSFP + isekela isilinganiso se-40GBIT / S Single-Channel, kanye ne-QSFP + DAC / AOC isekela isilinganiso sokudlulisa se-x 10. I-QSFP28 Module Transfers idatha ngesilinganiso se-100Gbit / s. I-QSFP28 DAC / AOC isekela ama-4 x 25gbit / s noma 2 x 50gbit / s. Qaphela ukuthi imodyuli ye-QSFP28 ayikwazi ukusetshenziselwa izixhumanisi zegatsha le-10G. Kodwa-ke, uma i-switch enamachweba we-QSFP28 isekela amamojula we-QSFP +, ungafaka amamojula we-QSFP + kumachweba we-QSFP20 ukuze usebenzise izixhumanisi zegatsha le-4 x.
