SFP
SFP irashobora kumvikana nka verisiyo yazamuye GBIC.Ingano yacyo ni 1/2 gusa cyi module ya GBIC, byongera cyane ubwinshi bwicyambu cyibikoresho byurusobe.Mubyongeyeho, igipimo cyo kohereza amakuru ya SFP kiri hagati ya 100Mbps kugeza 4Gbps.
SFP +
SFP + ni verisiyo yongerewe ya SFP ishyigikira umuyoboro wa fibre 8Gbit / s, 10G Ethernet na OTU2, urwego rwohereza imiyoboro ya optique.Mubyongeyeho, insinga zitaziguye za SFP + (ni ukuvuga, insinga ya SFP + DAC yihuta cyane na AOC ikora optique ya optique) irashobora guhuza ibyambu bibiri bya SFP + utiriwe wongeramo moderi ya optique hamwe ninsinga (insinga z'urusobe cyangwa fibre zisimbuka), ibyo bikaba ari amahitamo meza yo guhuza bitaziguye hagati bibiri byegeranye bigufi-intera ihuza imiyoboro.
SFP28
SFP28 ni verisiyo ishimishije ya SFP +, ifite ubunini bungana na SFP + ariko irashobora gushyigikira umuvuduko umwe wa 25Gb / s.SFP28 itanga igisubizo cyiza cyo kuzamura imiyoboro ya 10G-25G-100G kugirango ihuze ibikenewe byiterambere ryibisekuruza bizaza.
QSFP +
QSFP + ni verisiyo ivuguruye ya QSFP.Bitandukanye na QSFP +, ishyigikira imiyoboro 4 ya gbit / s ku gipimo cya 1Gbit / s, QSFP + ishyigikira imiyoboro ya 4 x 10Gbit / s ku gipimo cya 40Gbps.Ugereranije na SFP +, igipimo cyo kohereza QSFP + cyikubye inshuro enye ugereranije na SFP +.QSFP + irashobora gukoreshwa muburyo butaziguye mugihe hashyizweho umuyoboro wa 40G, bityo ukazigama ikiguzi no kongera ubwinshi bwicyambu.
QSFP28
QSFP28 itanga imiyoboro ine yihuta itandukanye.Igipimo cyo kohereza kuri buri muyoboro kiratandukanye kuva 25Gbps kugeza 40Gbps, gishobora kuzuza ibisabwa 100 gbit / s Ethernet (4 x 25Gbps) hamwe na EDR InfiniBand.Hariho ubwoko bwinshi bwibicuruzwa bya QSFP28, kandi uburyo butandukanye bwo kohereza 100 Gbit / s burakoreshwa, nka 100 Gbit / s ihuza itaziguye, 100 Gbit / s ihinduka kuri bine 25 Gbit / s, cyangwa 100 Gbit / s ihinduka kuri bibiri 50 Gbit / s ishami.
Itandukaniro nibisa na SFP, SFP +, SFP28, QSFP +, QSFP28
Nyuma yo gusobanukirwa icyo SFP, SFP +, SFP28, QSFP +, QSFP28 aricyo, ibisa bihuye nibitandukaniro byombi bizamenyekana ubutaha.

SFP na SFP +: Ingano imwe, ibiciro bitandukanye no guhuza
Ingano nigaragara bya moderi ya SFP na SFP + nimwe, kuburyo abakora ibikoresho bashobora gukoresha igishushanyo mbonera cya SFP kuri switch hamwe na port ya SFP +.Bitewe nubunini bumwe, abakiriya benshi bakoresha modul ya SFP kumyambu ya SFP +.Iki gikorwa kirashoboka, ariko igipimo cyaragabanutse kugera kuri 1Gbit / s.Mubyongeyeho, ntukoreshe module ya SFP + mumwanya wa SFP.Bitabaye ibyo, icyambu cyangwa module birashobora kwangirika.Usibye guhuza, SFP na SFP + bifite ibipimo byoherejwe hamwe nibipimo bitandukanye.SFP + irashobora kohereza ntarengwa ya 4Gbit / s hamwe na 10Gbit / s.SFP ishingiye kuri protocole ya SFF-8472 mugihe SFP + ishingiye kuri protocole ya SFF-8431 na SFF-8432.
SFP28 na SFP +: Module optique ya SFP28 irashobora guhuzwa nicyambu cya SFP +
Nkuko byavuzwe haruguru, SFP28 ni verisiyo yazamuye ya SFP + ifite ubunini bumwe ariko ibipimo bitandukanye byo kohereza.Igipimo cyo kohereza SFP + ni 10Gbit / s naho icya SFP28 ni 25Gbit / s.Niba module ya SFP + optique yinjijwe mu cyambu cya SFP28, igipimo cyo kohereza ni 10Gbit / s, naho ubundi.Byongeye kandi, SFP28 ihuza umugozi wumuringa ufite umurongo mwinshi kandi igihombo kiri munsi ya SFP + ihuza umugozi wumuringa.
SFP28 na QSFP28: ibipimo bya protocole biratandukanye
Nubwo SFP28 na QSFP28 byombi bitwara umubare "28", ingano zombi ziratandukanye na protocole.SFP28 ishyigikira umuyoboro umwe wa 25Gbit / s, naho QSFP28 ishyigikira imiyoboro ine 25Gbit / s.Byombi birashobora gukoreshwa kumurongo wa 100G, ariko muburyo butandukanye.QSFP28 irashobora kugera kuri 100G ikoresheje uburyo butatu bwavuzwe haruguru, ariko SFP28 yishingikiriza kuri QSFP28 kugeza kuri SFP28 ishami ryihuta.Igishushanyo gikurikira cyerekana isano itaziguye ya 100G QSFP28 kugeza 4 × SFP28 DAC.
QSFP na QSFP28: Ibiciro bitandukanye, porogaramu zitandukanye
Modire ya QSFP + na QSFP28 ifite ubunini bungana kandi ifite imiyoboro ine ihuriweho kandi yakira imiyoboro.Mubyongeyeho, imiryango yombi QSFP + na QSFP28 ifite module optique hamwe ninsinga za DAC / AOC yihuta, ariko kubiciro bitandukanye.Module ya QSFP + ishyigikira igipimo cya 40Gbit / s umuyoboro umwe, naho QSFP + DAC / AOC ishyigikira igipimo cya 4 x 10Gbit / s.Module ya QSFP28 yohereza amakuru ku gipimo cya 100Gbit / s.QSFP28 DAC / AOC ishyigikira 4 x 25Gbit / s cyangwa 2 x 50Gbit / s.Menya ko QSFP28 module idashobora gukoreshwa kumashami ya 10G.Ariko, niba uhinduranya ibyambu bya QSFP28 bishyigikira moderi ya QSFP +, urashobora kwinjiza QSFP + module mubyambu bya QSFP28 kugirango ushyire mubikorwa 4 x 10G.
