SFP
SFP inogona kunzwisiswa seyakakwidziridzwa vhezheni yeGBIC. Huwandu hwayo ingori 1/2 chete yeiyo GBIC module, iyo inowedzera zvakanyanya kuwanda kwechiteshi chemidziyo yetiweki. Mukuwedzera, iyo SFP's data transfer rates inotangira pa100Mbps kusvika ku4Gbps.
SFP+
SFP + ishanduro yakagadziridzwa yeSFP inotsigira 8Gbit/s fiber channel, 10G Ethernet uye OTU2, iyo optical transmission network standard. Mukuwedzera, SFP + tambo dzakananga (kureva, SFP + DAC high-speed cables uye AOC active optical cables) inogona kubatanidza maviri SFP + ports pasina kuwedzera mamwe optical modules uye tambo (network cables kana fiber jumpers), iyo isarudzo yakanaka yekubatanidza zvakananga pakati. maviri ari padyo neshort-distance network switch.
SFP28
Iyo SFP28 ishanduro yakagadziridzwa yeSFP +, ine saizi yakafanana neSFP + asi inogona kutsigira imwe-chiteshi kumhanya kwe25Gb/s. SFP28 inopa mhinduro inoshanda yekusimudzira 10G-25G-100G network kuti isangane nekukura kwezvinodiwa zvechizvarwa chinotevera data center network.
QSFP+
QSFP+ ishanduro yakagadziridzwa yeQSFP. Kusiyana neQSFP +, iyo inotsigira 4 gbit / s migero pamwero we1Gbit/s, QSFP + inotsigira 4 x 10Gbit/s chiteshi pamwero we40Gbps. Kuenzaniswa neSFP +, chiyero chekufambisa cheQSFP + chakapetwa kana kupfuura cheSFP +. QSFP + inogona kushandiswa zvakananga kana network ye40G ichiiswa, nekudaro ichichengetedza mutengo uye kuwedzera port density.
QSFP28
Iyo QSFP28 inopa ina yakakwirira-kumhanya yekusiyanisa masaini masaini. Chiyero chekufambisa kwechiteshi chimwe nechimwe chinosiyana kubva ku25Gbps kusvika ku40Gbps, iyo inogona kusangana nezvinodiwa zve100 gbit / s Ethernet (4 x 25Gbps) uye EDR InfiniBand kushandiswa. Kune marudzi akawanda ezvigadzirwa zveQSFP28, uye nzira dzakasiyana dze100 Gbit/s transmission dzinoshandiswa, dzakadai se100 Gbit/s direct connection, 100 Gbit/s conversion kusvika mana 25 Gbit/s branch links, kana 100 Gbit/s conversion to. maviri 50 Gbit/s bazi links.

SFP uye SFP +: Saizi yakafanana, mareti akasiyana uye kuenderana
Saizi uye chitarisiko cheSFP uye SFP + modules dzakafanana, saka vagadziri vemidziyo vanogona kutora dhizaini yeSFP pane switch neSFP + ports. Nekuda kwehukuru hwakafanana, vatengi vazhinji vanoshandisa SFP modules paSFP + ports ye switch. Kuvhiya uku kunogoneka, asi mwero wakaderedzwa kusvika ku1Gbit/s. Mukuwedzera, usashandise SFP + module muSFP slot. Zvikasadaro, chiteshi kana module inogona kukuvara. Pamusoro pekuenderana, SFP neSFP + vane mazinga akasiyana ekutapurirana uye zviyero. SFP+ inogona kutumira huwandu hwe4Gbit/s uye huwandu hwe10Gbit/s. SFP yakavakirwa paSFF-8472 protocol ukuwo SFP+ yakavakirwa paSFF-8431 uye SFF-8432 protocol.
SFP28 uye SFP +: Iyo SFP28 Optical module inogona kubatana kune SFP + port
Sezvambotaurwa pamusoro, SFP28 ishanduro yakakwidziridzwa yeSFP+ ine saizi yakafanana asi akasiyana mareti ekutapurirana. Nhamba yekufambisa yeSFP+ i10Gbit/s uye iyo yeSFP28 i25Gbit/s. Kana iyo SFP + optical module ikaiswa muSFP28 port, iyo link yekufambisa mwero ndeye 10Gbit/s, uye zvinopesana. Mukuwedzera, SFP28 yakanyatsobatanidza tambo yemhangura ine yakakwirira bandwidth uye yakaderera kurasikirwa kupfuura SFP + yakabatana yakananga tambo yemhangura.
SFP28 uye QSFP28: mitemo yeprotocol yakasiyana
Kunyange zvazvo zvose SFP28 neQSFP28 zvinotakura nhamba "28", saizi mbiri dzakasiyana kubva kune protocol standard. Iyo SFP28 inotsigira 25Gbit / s imwe chiteshi, uye QSFP28 inotsigira ina 25Gbit / s nzira. Ose ari maviri anogona kushandiswa pane 100G network, asi nenzira dzakasiyana. QSFP28 inogona kuwana 100G kutapurirwa kuburikidza nenzira nhatu dzataurwa pamusoro apa, asi SFP28 inovimba neQSFP28 kusvika kuSFP28 yebazi repamusoro-speed cables. Nhamba inotevera inoratidza kubatana kwakananga kwe100G QSFP28 ku4 × SFP28 DAC.
QSFP uye QSFP28: Matengo akasiyana, akasiyana maapplication
Iyo QSFP + uye QSFP28 optical modules ndeye saizi yakafanana uye ine ina yakabatanidzwa inotapurirana uye inogashira nzira. Mukuwedzera, zvose QSFP + uye QSFP28 mhuri dzine optical modules uye DAC / AOC high-speed cables, asi pamitengo yakasiyana. Iyo QSFP + module inotsigira 40Gbit / s single-channel rate, uye QSFP + DAC/AOC inotsigira 4 x 10Gbit / s kutengesa. Iyo QSFP28 module inotamisa data pamwero we100Gbit/s. Iyo QSFP28 DAC/AOC inotsigira 4 x 25Gbit/s kana 2 x 50Gbit/s. Ziva kuti QSFP28 module haigone kushandiswa kune 10G bazi link. Zvisinei, kana shanduko ine QSFP28 ports inotsigira QSFP + modules, unogona kuisa QSFP + modules muQSFP28 ports kuti uite 4 x 10G bazi links.
