SFP
SFP ishobora kumvikana nk'ivuguruye rya GBIC. Ingano yayo ni kimwe cya kabiri cy'iya module ya GBIC, ibyo bikaba byongera cyane ubucucike bw'ibikoresho bya interineti. Byongeye kandi, igipimo cyo kohereza amakuru cya SFP kiri hagati ya 100Mbps na 4Gbps.
SFP+
SFP+ ni verisiyo ya SFP igezweho ishyigikira umuyoboro wa fibre wa 8Gbit/s, 10G Ethernet na OTU2, umurongo ngenderwaho w’itumanaho rya optique. Byongeye kandi, insinga za SFP+ (ni ukuvuga insinga zihuta cyane za SFP+ DAC n’insinga zikora za optique za AOC) zishobora guhuza imiyoboro ibiri ya SFP+ hatabayeho kongeramo modules na insinga za optique (insinga za network cyangwa fibre jumpers), ikaba ari amahitamo meza yo guhuza mu buryo butaziguye hagati y’udushya tubiri tw’itumanaho twegeranye two mu ntera ngufi.
SFP28
SFP28 ni verisiyo ya SFP+ igezweho, ifite ingano imwe na SFP+ ariko ishobora gushyigikira umuvuduko wa 25Gb/s. SFP28 itanga igisubizo cyiza cyo kuvugurura imiyoboro ya 10G-25G-100G kugira ngo ihuze n'ibikenewe cyane by'imiyoboro y'amakuru yo mu gisekuru gitaha.
QSFP+
QSFP+ ni verisiyo ivuguruye ya QSFP. Bitandukanye na QSFP+, ishyigikira imiyoboro ya 4 gbit / s ku gipimo cya 1Gbit / s, QSFP + ishyigikira imiyoboro ya 4 x 10Gbit / s ku gipimo cya 40Gbps. Ugereranyije na SFP+, igipimo cyo kohereza amakuru cya QSFP + kiri hejuru inshuro enye kurusha icya SFP +. QSFP + ishobora gukoreshwa mu buryo butaziguye iyo umuyoboro wa 40G ushyizwemo, bityo bikagabanya ikiguzi kandi bikongera ubucucike bw'imiyoboro.
QSFP28
QSFP28 itanga imiyoboro ine y’ibimenyetso bihindagurika cyane. Igipimo cyo kohereza amakuru kuri buri muyoboro kiratandukanye kuva kuri 25Gbps kugeza kuri 40Gbps, gishobora kuzuza ibisabwa na Ethernet ya 100 gbit/s (4 x 25Gbps) na porogaramu za EDR InfiniBand. Hari ubwoko bwinshi bw’ibicuruzwa bya QSFP28, kandi uburyo butandukanye bwo kohereza amakuru bwa 100 Gbit/s bukoreshwa, nko guhuza 100 Gbit/s, guhindura 100 Gbit/s mu mashami ane ya 25 Gbit/s, cyangwa guhindura 100 Gbit/s mu mashami abiri ya 50 Gbit/s.

Nyuma yo gusobanukirwa icyo SFP, SFP+, SFP28, QSFP+, QSFP28 ari cyo, hazakurikiraho ibintu bisa n'ibitandukanye hagati yabyo.

SFP na SFP+: Ingano imwe, ibipimo bitandukanye n'uburyo bihuzwa
Ingano n'isura ya module za SFP na SFP+ ni bimwe, bityo abakora ibikoresho bashobora gukoresha imiterere ya SFP ku ma switch afite port za SFP+. Kubera ingano imwe, abakiriya benshi bakoresha module za SFP ku ma switch za SFP+. Iki gikorwa kirashoboka, ariko igipimo kiragabanuka kikagera kuri 1Gbit/s. Byongeye kandi, ntugakoreshe module ya SFP+ muri SFP. Bitabaye ibyo, port cyangwa module ishobora kwangirika. Uretse kuba ihuye, SFP na SFP+ bifite igipimo n'amahame bitandukanye byo kohereza. SFP+ ishobora kohereza ntarengwa ya 4Gbit/s na ntarengwa ya 10Gbit/s. SFP ishingiye kuri protocole ya SFF-8472 mu gihe SFP+ ishingiye kuri protocole za SFF-8431 na SFF-8432.
SFP28 na SFP+: Module ya optique ya SFP28 ishobora guhuzwa na port ya SFP+
Nkuko byavuzwe haruguru, SFP28 ni verisiyo yavuguruye ya SFP+ ifite ingano imwe ariko ifite igipimo cyo kohereza gitandukanye. Igipimo cyo kohereza cya SFP+ ni 10Gbit/s naho icya SFP28 kikaba 25Gbit/s. Iyo module ya optique ya SFP+ yinjijwe muri port ya SFP28, igipimo cyo kohereza gihuza ni 10Gbit/s, naho ibinyuranye. Byongeye kandi, insinga y'umuringa ya SFP28 ifite umurambararo munini kandi igihombo gito ugereranyije n'insinga y'umuringa ya SFP+ ihujwe nayo.
SFP28 na QSFP28: amahame ngenderwaho aratandukanye
Nubwo SFP28 na QSFP28 byombi bifite inomero "28", ingano zombi ziratandukanye n'ibipimo ngenderwaho bya protocole. SFP28 ishyigikira umuyoboro umwe wa 25Gbit/s, naho QSFP28 ishyigikira imiyoboro ine ya 25Gbit/s. Zombi zishobora gukoreshwa ku miyoboro ya 100G, ariko mu buryo butandukanye. QSFP28 ishobora kugera ku kohereza 100G binyuze mu buryo butatu bwavuzwe haruguru, ariko SFP28 ikoresha insinga zihuta cyane za QSFP28 kuri SFP28. Ishusho ikurikira igaragaza isano itaziguye ya 100G QSFP28 kuri 4×SFP28 DAC.
QSFP na QSFP28: Ibiciro bitandukanye, porogaramu zitandukanye
Moduli za QSFP+ na QSFP28 zifite ingano imwe kandi zifite imiyoboro ine yashyizwe hamwe yo kohereza no kwakira. Byongeye kandi, imiryango ya QSFP+ na QSFP28 ifite module za optique na insinga zihuta za DAC/AOC, ariko ku gipimo gitandukanye. Moduli ya QSFP+ ishyigikira igipimo cya 40Gbit/s cy’umuyoboro umwe, naho QSFP+ DAC/AOC ishyigikira igipimo cya 4 x 10Gbit/s cyo kohereza amakuru. Moduli ya QSFP28 yohereza amakuru ku gipimo cya 100Gbit/s. QSFP28 DAC/AOC ishyigikira 4 x 25Gbit/s cyangwa 2 x 50Gbit/s. Menya ko module ya QSFP28 idashobora gukoreshwa ku miyoboro ya 10G. Ariko, niba switch ifite imiyoboro ya QSFP28 ishyigikira module za QSFP+, ushobora gushyiramo module za QSFP+ muri miyoboro ya QSFP28 kugira ngo ushyire mu bikorwa imiyoboro ya 4 x 10G.
