SFP
SFP ikhoza kumveka ngati mtundu wokwezedwa wa GBIC. Voliyumu yake ndi 1/2 yokha ya module ya GBIC, yomwe imakulitsa kwambiri kachulukidwe ka doko la zida zama network. Kuphatikiza apo, mitengo yosinthira deta ya SFP imachokera ku 100Mbps mpaka 4Gbps.
SFP +
SFP + ndi njira yowonjezera ya SFP yomwe imathandizira 8Gbit / s fiber channel, 10G Ethernet ndi OTU2, optical transmission network standard. Kuphatikiza apo, zingwe zolunjika za SFP + (ie, zingwe zothamanga kwambiri za SFP + DAC ndi zingwe za AOC zogwira ntchito) zimatha kulumikiza madoko awiri a SFP + popanda kuwonjezera ma module owonjezera ndi zingwe (zingwe za netiweki kapena ma fiber jumpers), chomwe ndi chisankho chabwino cholumikizira mwachindunji pakati pawo. ma switch awiri oyandikana mtunda waufupi.
SFP28
SFP28 ndi mtundu wowonjezereka wa SFP +, womwe uli ndi kukula kofanana ndi SFP + koma ukhoza kuthandizira kuthamanga kwa njira imodzi ya 25Gb / s. SFP28 imapereka yankho lothandiza pakukweza maukonde a 10G-25G-100G kuti akwaniritse zosowa zomwe zikuchulukirachulukira zamagulu am'badwo wotsatira.
QSFP +
QSFP+ ndi mtundu wosinthidwa wa QSFP. Mosiyana ndi QSFP +, yomwe imathandizira njira za 4 gbit / s pa mlingo wa 1Gbit / s, QSFP + imathandizira njira za 4 x 10Gbit / s pa mlingo wa 40Gbps. Poyerekeza ndi SFP +, mlingo wotumizira wa QSFP + ndi wokwera kanayi kuposa wa SFP +. QSFP + ingagwiritsidwe ntchito mwachindunji pamene intaneti ya 40G ikugwiritsidwa ntchito, potero kupulumutsa mtengo ndi kuwonjezeka kwa doko.
QSFP28
QSFP28 imapereka njira zinayi zosiyanitsira zothamanga kwambiri. Kuthamanga kwa njira iliyonse kumasiyana kuchokera ku 25Gbps kupita ku 40Gbps, zomwe zingathe kukwaniritsa zofunikira za 100 gbit / s Ethernet (4 x 25Gbps) ndi EDR InfiniBand ntchito. Pali mitundu yambiri ya zinthu za QSFP28, ndipo njira zosiyanasiyana zotumizira 100 Gbit/s zimagwiritsidwa ntchito, monga kulumikiza mwachindunji kwa 100 Gbit/s, kutembenuka kwa 100 Gbit/s kukhala maulalo anayi anthambi a 25 Gbit/s, kapena kutembenuza kwa 100 Gbit/s ku maulalo awiri a 50 Gbit/s nthambi.
Kusiyana ndi kufanana kwa SFP, SFP+, SFP28, QSFP+, QSFP28
Pambuyo pomvetsetsa zomwe SFP, SFP +, SFP28, QSFP +, QSFP28 zili, kufanana kwapadera ndi kusiyana pakati pa awiriwa kudzafotokozedwa motsatira.

SFP ndi SFP +: Kukula komweko, mitengo yosiyana komanso kuyanjana
Kukula ndi maonekedwe a SFP ndi SFP + ma modules ndi ofanana, kotero opanga zipangizo amatha kutengera mawonekedwe a SFP pa ma switch omwe ali ndi madoko a SFP +. Chifukwa cha kukula komweko, makasitomala ambiri amagwiritsa ntchito ma module a SFP pa madoko a SFP + osinthira. Izi ndi zotheka, koma mlingo watsitsidwa mpaka 1Gbit/s. Kuphatikiza apo, musagwiritse ntchito SFP + module mu SFP slot. Apo ayi, doko kapena module ikhoza kuonongeka. Kuphatikiza pa kuyanjana, SFP ndi SFP + ali ndi maulendo osiyanasiyana opatsirana ndi miyezo. SFP+ imatha kutumiza ma 4Gbit/s opitilira 10Gbit/s. SFP imachokera ku protocol ya SFF-8472 pomwe SFP + imachokera ku SFF-8431 ndi SFF-8432 protocol.
SFP28 ndi SFP +: SFP28 Optical module imatha kulumikizidwa ndi doko la SFP +
Monga tafotokozera pamwambapa, SFP28 ndi mtundu wosinthika wa SFP + wokhala ndi kukula kofanana koma mitengo yopatsirana yosiyana. Mlingo wotumizira wa SFP+ ndi 10Gbit/s ndipo wa SFP28 ndi 25Gbit/s. Ngati SFP + Optical module ilowetsedwa mu doko la SFP28, mlingo wotumizira ulalo ndi 10Gbit / s, ndi mosemphanitsa. Kuphatikiza apo, chingwe chamkuwa cholumikizidwa mwachindunji cha SFP28 chimakhala ndi bandwidth yapamwamba komanso kutayika kochepa kuposa chingwe chamkuwa cholumikizidwa mwachindunji ndi SFP +.
SFP28 ndi QSFP28: miyezo ya protocol ndi yosiyana
Ngakhale SFP28 ndi QSFP28 zili ndi nambala "28", kukula kwake kumasiyana ndi muyezo wa protocol. SFP28 imathandizira njira imodzi ya 25Gbit / s, ndipo QSFP28 imathandizira njira zinayi za 25Gbit / s. Zonsezi zitha kugwiritsidwa ntchito pamanetiweki a 100G, koma m'njira zosiyanasiyana. QSFP28 ikhoza kukwaniritsa kutumiza kwa 100G kupyolera mu njira zitatu zomwe tazitchula pamwambapa, koma SFP28 imadalira QSFP28 ku SFP28 zingwe zothamanga kwambiri za nthambi. Chithunzi chotsatira chikuwonetsa kugwirizana kwachindunji kwa 100G QSFP28 ku 4 × SFP28 DAC.
QSFP ndi QSFP28: Mitengo yosiyana, ntchito zosiyanasiyana
Ma module a QSFP + ndi QSFP28 optical ndi ofanana kukula ndipo ali ndi njira zinayi zophatikizira zotumizira ndi kulandira. Kuonjezera apo, mabanja onse a QSFP + ndi QSFP28 ali ndi ma modules optical ndi DAC / AOC zingwe zothamanga kwambiri, koma pamitengo yosiyana. Gawo la QSFP + limathandizira 40Gbit / s njira imodzi yokha, ndipo QSFP + DAC / AOC imathandizira 4 x 10Gbit / s mlingo wotumizira. Gawo la QSFP28 limasamutsa deta pamlingo wa 100Gbit / s. QSFP28 DAC/AOC imathandizira 4 x 25Gbit/s kapena 2 x 50Gbit/s. Dziwani kuti gawo la QSFP28 silingagwiritsidwe ntchito pazolumikizana ndi nthambi za 10G. Komabe, ngati kusinthana ndi madoko a QSFP28 kumathandizira ma module a QSFP +, mutha kuyika ma module a QSFP + m'madoko a QSFP28 kuti mugwiritse ntchito maulalo a nthambi 4 x 10G.
