SFP
I-SFP inokuqondwa njengoguqulelo oluphuculweyo lwe-GBIC. Umthamo wayo ngu-1/2 kuphela wemodyuli ye-GBIC, eyandisa kakhulu i-port density yezixhobo zenethiwekhi. Ukongezelela, amazinga okudluliselwa kwedatha ye-SFP avela kwi-100Mbps ukuya kwi-4Gbps.
SFP+
I-SFP + yinguqu ephuculweyo ye-SFP exhasa i-8Gbit / s i-fiber channel, i-10G Ethernet kunye ne-OTU2, umgangatho wothungelwano lwe-optical transmission network. Ukongeza, iintambo ezithe ngqo ze-SFP + (oko kukuthi, iintambo ze-SFP + DAC ezinesantya esiphezulu kunye ne-AOC esebenzayo i-optical cables) zinokudibanisa izibuko ezimbini ze-SFP + ngaphandle kokongeza iimodyuli ze-optical ezongezelelweyo kunye neentambo (iintambo zenethiwekhi okanye i-fiber jumpers), ukhetho olufanelekileyo lokuxhamla ngokuthe ngqo phakathi kweeswitshi ezimbini zenethiwekhi ezikufutshane ezikufutshane.
SFP28
I-SFP28 yinguqulo ephuculweyo ye-SFP +, enobukhulu obufanayo ne-SFP + kodwa inokuxhasa isantya sesiteshi esisodwa se-25Gb / s. I-SFP28 ibonelela ngesisombululo esisebenzayo sokuphucula amanethiwekhi e-10G-25G-100G ukuhlangabezana neemfuno ezikhulayo zothungelwano lwedatha yedatha yesizukulwana esilandelayo.
QSFP+
I-QSFP+ yinguqulelo ehlaziyiweyo ye-QSFP. Ngokungafani ne-QSFP +, exhasa iziteshi ze-4 gbit / s kwizinga le-1Gbit / s, i-QSFP + isekela i-4 x 10Gbit / s iziteshi kwizinga le-40Gbps. Xa kuthelekiswa ne-SFP +, izinga lokudluliselwa kwe-QSFP + liphindwe kane ngaphezu kwe-SFP +. I-QSFP + ingasetyenziswa ngokuthe ngqo xa inethiwekhi ye-40G isetyenziswe, ngaloo ndlela igcina iindleko kunye nokwandisa ubuninzi be-port.
QSFP28
I-QSFP28 ibonelela ngeendlela ezine zokwahluka kwesantya esiphezulu. Izinga lokudluliselwa kweshaneli nganye lihluka ukusuka kwi-25Gbps ukuya kwi-40Gbps, enokufikelela kwiimfuno ze-100 gbit / s Ethernet (4 x 25Gbps) kunye ne-EDR InfiniBand izicelo. Kukho iintlobo ezininzi zeemveliso ze-QSFP28, kunye neendlela ezahlukeneyo zokudluliselwa kwe-100 Gbit / s zisetyenzisiweyo, ezifana ne-100 Gbit / s uxhulumaniso oluthe ngqo, ukuguqulwa kwe-100 Gbit / s kwiikhonkco ezine ze-25 Gbit / s, okanye ukuguqulwa kwe-100 Gbit / s ukuya kwii-2 ze-50 Gbit / s zesebe.
Umahluko kunye nokufana kwe-SFP, SFP +, SFP28, QSFP +, QSFP28
Emva kokuqonda ukuba yiyiphi i-SFP, i-SFP +, i-SFP28, i-QSFP +, i-QSFP28, ukufana okuthe ngqo kunye nokuhlukana phakathi kwezi zibini kuya kuqaliswa ngokulandelayo.

I-SFP kunye ne-SFP + : Ubungakanani obufanayo, amaxabiso ahlukeneyo kunye nokuhambelana
Ubungakanani kunye nokubonakala kweemodyuli ze-SFP kunye ne-SFP + ziyafana, ngoko ke abavelisi besixhobo banokumkela uyilo lomzimba we-SFP ekutshintsheni kunye ne-SFP + port. Ngenxa yobukhulu obufanayo, abathengi abaninzi basebenzisa iimodyuli ze-SFP kwi-SFP + izibuko zokutshintsha. Lo msebenzi unokwenzeka, kodwa izinga liyancitshiswa ukuya kwi-1Gbit/s. Ukongeza, ungasebenzisi imodyuli ye-SFP + kwi-slot slot. Ngaphandle koko, izibuko okanye imodyuli inokonakala. Ukongeza kokuhambelana, i-SFP kunye ne-SFP + zinemigangatho eyahlukeneyo yokuhambisa kunye nemigangatho. I-SFP + inokudlulisa ubuninzi be-4Gbit / s kunye nobuninzi be-10Gbit / s. I-SFP isekelwe kwiprotocol ye-SFF-8472 ngelixa i-SFP + isekelwe kwi-SFF-8431 kunye ne-SFF-8432 protocol.
I-SFP28 kunye ne-SFP+: Imodyuli ye-SFP28 yokukhanya inokudityaniswa kwi-port ye-SFP+
Njengoko kukhankanyiwe ngasentla, i-SFP28 yinguqulelo ephuculweyo ye-SFP + enobungakanani obufanayo kodwa amazinga othumelo ahlukeneyo. Izinga lokudluliselwa kwe-SFP + yi-10Gbit / s kunye ne-SFP28 yi-25Gbit / s. Ukuba imodyuli ye-SFP + ye-optical ifakwe kwi-port ye-SFP28, izinga lokudluliselwa kwekhonkco liyi-10Gbit / s, kunye nelinye icala. Ukongeza, i-SFP28 iqhagamshelwe ngokuthe ngqo intambo yethusi ine-bandwidth ephezulu kunye nelahleko ephantsi kune-SFP + eqhagamshelwe ngokuthe ngqo ikhebula lobhedu.
