SFP
SFP inogona kunzwisiswa seshanduro yakagadziridzwa yeGBIC. Vhoriyamu yayo inongova chikamu chimwe chete muzvina cheGBIC module, izvo zvinowedzera zvakanyanya huwandu hweport density yenetwork devices. Pamusoro pezvo, mwero wekutamisa data weSFP unotangira pa100Mbps kusvika pa4Gbps.
SFP+
SFP+ ishanduro yakagadziridzwa yeSFP inotsigira 8Gbit/s fiber channel, 10G Ethernet neOTU2, iyo inowanzo shandiswa ne optical transmission network. Pamusoro pezvo, SFP+ direct cables (kureva, SFP+ DAC high-speed cables uye AOC active optical cables) dzinogona kubatanidza maSFP+ ports maviri pasina kuwedzera mamwe ma optical modules ne cables (network cables kana fiber jumpers), inova sarudzo yakanaka yekubatanidza zvakananga pakati pema switch maviri e network ari pedyo.
SFP28
SFP28 ishanduro yakagadziridzwa yeSFP+, ine saizi yakafanana neSFP+ asi inogona kutsigira kumhanya kwechiteshi chimwe chete kwe25Gb/s. SFP28 inopa mhinduro inoshanda yekuvandudza network dze10G-25G-100G kuti dzigutse zvinodiwa zviri kukura zve network dzedata center dzechizvarwa chinotevera.
QSFP+
QSFP+ ishanduro yakagadziridzwa yeQSFP. Kusiyana neQSFP+, iyo inotsigira nzira dze4 gbit / s pachiyero che1Gbit / s, QSFP + inotsigira nzira dze4 x 10Gbit / s pachiyero che40Gbps. Kana ichienzaniswa neSFP+, chiyero chekutumira cheQSFP + chakapetwa kana kupfuura cheSFP +. QSFP + inogona kushandiswa zvakananga kana network ye40G yaiswa, nokudaro ichichengetedza mari uye ichiwedzera huwandu hweport.
QSFP28
QSFP28 inopa nzira ina dzechiratidzo dzinomhanya zvakanyanya. Mwero wekutumirwa kwechiteshi chimwe nechimwe unosiyana kubva pa25Gbps kusvika ku40Gbps, izvo zvinogona kusangana nezvinodiwa zve100 gbit/s Ethernet (4 x 25Gbps) uye EDR InfiniBand applications. Kune mhando dzakawanda dzezvigadzirwa zveQSFP28, uye nzira dzakasiyana dzekutumira 100 Gbit/s dzinoshandiswa, dzakadai sekubatanidza zvakananga kwe100 Gbit/s, kushandura 100 Gbit/s kuita mana e25 Gbit/s branch links, kana kushandura 100 Gbit/s kuita maviri e50 Gbit/s branch links.

SFP neSFP+: Saizi imwe chete, mitengo yakasiyana uye kuenderana kwakasiyana
Saizi uye chitarisiko chemamodule eSFP neSFP+ zvakafanana, saka vagadziri vemidziyo vanogona kushandisa dhizaini chaiyo yeSFP pamaswichi ane maports eSFP+. Nekuda kwehukuru hwakaenzana, vatengi vazhinji vanoshandisa mamodule eSFP pamaports eSFP+ emaswichi. Izvi zvinogoneka, asi chiyero chinoderedzwa kusvika ku1Gbit/s. Pamusoro pezvo, musashandise module yeSFP+ muSFP slot. Zvikasadaro, chiteshi kana module inogona kukuvara. Pamusoro pekuenderana, SFP neSFP+ dzine mwero wekutumira uye zviyero zvakasiyana. SFP+ inogona kutumira huwandu hwakanyanya hwe4Gbit/s uye huwandu hwakanyanya hwe10Gbit/s. SFP yakavakirwa paprotocol yeSFF-8472 nepo SFP+ yakavakirwa paprotocol dzeSFF-8431 neSFF-8432.
SFP28 neSFP+: SFP28 optical module inogona kubatanidzwa neSFP+ port
Sezvambotaurwa pamusoro apa, SFP28 ishanduro yakagadziridzwa yeSFP+ ine saizi imwe chete asi mwero wekutumira wakasiyana. Mwero wekutumira weSFP+ i10Gbit/s uye weSFP28 i25Gbit/s. Kana SFP+ optical module ikaiswa muSFP28 port, mwero wekutumira wekubatanidza i10Gbit/s, uye zvinopesana. Pamusoro pezvo, SFP28 directly connected copper cable ine bandwidth yakakwira uye kurasikirwa kwakaderera pane SFP+ directly connected copper cable.
SFP28 neQSFP28: mitemo yeprotocol yakasiyana
Kunyangwe zvese SFP28 neQSFP28 zvine nhamba "28", saizi dzese dzakasiyana neprotocol standard. SFP28 inotsigira chiteshi chimwe che25Gbit/s, uye QSFP28 inotsigira nzira ina dze25Gbit/s. Dzese dzinogona kushandiswa pamanetwork e100G, asi nenzira dzakasiyana. QSFP28 inogona kuwana 100G transmission kuburikidza nenzira nhatu dzataurwa pamusoro apa, asi SFP28 inoshandisa QSFP28 kuenda kuSFP28 branch high-speed cables. Mufananidzo unotevera unoratidza kubatana kwakananga kwe100G QSFP28 kuenda ku4×SFP28 DAC.
QSFP neQSFP28: Mitengo yakasiyana, mashandisirwo akasiyana
Ma QSFP+ ne QSFP28 optical modules ane saizi imwe chete uye ane nzira ina dzakasanganiswa dzekutumira nekugamuchira. Pamusoro pezvo, mhuri dzese dze QSFP+ ne QSFP28 dzine ma optical modules ne DAC/AOC high-speed cables, asi nemitengo yakasiyana. QSFP+ module inotsigira 40Gbit/s single-channel rate, uye QSFP+ DAC/AOC inotsigira 4 x 10Gbit/s transmission rate. QSFP28 module inotumira data nemutengo we 100Gbit/s. QSFP28 DAC/AOC inotsigira 4 x 25Gbit/s kana 2 x 50Gbit/s. Cherechedza kuti QSFP28 module haigone kushandiswa kune 10G branch links. Zvisinei, kana switch ine QSFP28 ports ichitsigira QSFP+ modules, unogona kuisa QSFP+ modules muma QSFP28 ports kuti uite 4 x 10G branch links.
