I-SFP
I-SFP inokuqondwa njengenguqulelo ephuculweyo ye-GBIC. Umthamo wayo yi-1/2 kuphela yowemodyuli ye-GBIC, nto leyo enyusa kakhulu uxinano lwezibuko zezixhobo zenethiwekhi. Ukongeza, amazinga okudluliselwa kwedatha ye-SFP aqala kwi-100Mbps ukuya kwi-4Gbps.
I-SFP+
I-SFP+ yinguqulelo ephuculweyo ye-SFP exhasa itshaneli yefayibha ye-8Gbit/s, i-10G Ethernet kunye ne-OTU2, umgangatho wenethiwekhi yokudlulisa optical. Ukongeza, iintambo ezithe ngqo ze-SFP+ (oko kukuthi, iintambo ezikhawulezayo ze-SFP+ DAC kunye neentambo ezisebenza nge-AOC) zinokuqhagamshela ii-port ezimbini ze-SFP+ ngaphandle kokongeza iimodyuli ezongezelelweyo ze-optical kunye neentambo (iintambo zenethiwekhi okanye ii-fiber jumpers), olu lukhetho olufanelekileyo lokunxibelelana ngqo phakathi kweeswitshi ezimbini zenethiwekhi ezikufutshane.
I-SFP28
I-SFP28 yinguqulelo ephuculweyo ye-SFP+, enobukhulu obufanayo ne-SFP+ kodwa inokuxhasa isantya se-single-channel se-25Gb/s. I-SFP28 ibonelela ngesisombululo esisebenzayo sokuphucula iinethiwekhi ze-10G-25G-100G ukuze kuhlangatyezwane neemfuno ezikhulayo zeenethiwekhi zeziko ledatha zesizukulwana esilandelayo.
QSFP+
I-QSFP+ yinguqulelo ehlaziyiweyo ye-QSFP. Ngokungafaniyo ne-QSFP+, exhasa iitshaneli ze-4 gbit /s ngesantya se-1Gbit / s, i-QSFP + ixhasa iitshaneli ze-4 x 10Gbit / s ngesantya se-40Gbps. Xa kuthelekiswa ne-SFP+, izinga lokudlulisela le-QSFP + liphindwe kane kunele-SFP+. I-QSFP + ingasetyenziswa ngokuthe ngqo xa kusetyenziswa inethiwekhi ye-40G, ngaloo ndlela konga iindleko kwaye kwandiswe uxinano lwezibuko.
QSFP28
I-QSFP28 inika iindlela ezine zokubonisa umahluko ngesantya esiphezulu. Izinga lokudlulisela itshaneli nganye liyahluka ukusuka kwi-25Gbps ukuya kwi-40Gbps, enokwanelisa iimfuno ze-100 gbit/s Ethernet (4 x 25Gbps) kunye nezicelo ze-EDR InfiniBand. Kukho iintlobo ezininzi zeemveliso ze-QSFP28, kwaye kusetyenziswa iindlela ezahlukeneyo zokudlulisela i-100 Gbit/s, ezifana noqhagamshelo oluthe ngqo lwe-100 Gbit/s, ukuguqulwa kwe-100 Gbit/s ukuya kwiikhonkco ezine zesebe ze-25 Gbit/s, okanye ukuguqulwa kwe-100 Gbit/s ukuya kwiikhonkco ezimbini zesebe ze-50 Gbit/s.
Umahluko kunye nokufana kwe-SFP, SFP+, SFP28, QSFP+, QSFP28
Emva kokuqonda ukuba zeziphi ii-SFP, SFP+, SFP28, QSFP+, QSFP28, ukufana kunye nomahluko phakathi kwezi zimbini kuza kwaziswa ngokulandelayo.

I-SFP kunye ne-SFP+: Ubungakanani obufanayo, amazinga ahlukeneyo kunye nokuhambelana
Ubungakanani kunye nembonakalo yeemodyuli ze-SFP kunye ne-SFP+ ziyafana, ngoko ke abavelisi bezixhobo banokusebenzisa uyilo olubonakalayo lwe-SFP kwiiswitshi ezineeports ze-SFP+. Ngenxa yobukhulu obufanayo, abathengi abaninzi basebenzisa iimodyuli ze-SFP kwiiports ze-SFP+ zeeswitshi. Olu sebenzi lunokwenzeka, kodwa izinga lincitshisiwe liye kwi-1Gbit/s. Ukongeza, musa ukusebenzisa imodyuli ye-SFP+ kwisloti ye-SFP. Ngaphandle koko, iport okanye imodyuli inokonakala. Ukongeza ekuhambelaneni, i-SFP kunye ne-SFP+ zinamazinga othumelo ahlukeneyo 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 kwiprotocol ze-SFF-8431 kunye ne-SFF-8432.
I-SFP28 kunye ne-SFP+: Imodyuli ye-optical ye-SFP28 inokuqhagamshelwa kwizibuko le-SFP+
Njengoko kukhankanyiwe apha ngasentla, i-SFP28 yinguqulelo ephuculweyo ye-SFP+ enobukhulu obufanayo kodwa amazinga othumelo ahlukeneyo. Izinga lothumelo lwe-SFP+ yi-10Gbit/s kwaye elo le-SFP28 yi-25Gbit/s. Ukuba i-SFP+ optical module ifakwe kwi-SFP28 port, izinga lothumelo lwekhonkco yi-10Gbit/s, kwaye ngokuchaseneyo. Ukongeza, i-SFP28 eqhagamshelwe ngqo yintambo yobhedu ine-bandwidth ephezulu kunye nelahleko ephantsi kune-SFP+ eqhagamshelwe ngqo yintambo yobhedu.
I-SFP28 kunye ne-QSFP28: imigangatho yeprotocol yahlukile
Nangona zombini i-SFP28 kunye ne-QSFP28 zinenombolo "28", zombini ubungakanani zahlukile kumgangatho weprotocol. I-SFP28 ixhasa itshaneli enye ye-25Gbit/s, kwaye i-QSFP28 ixhasa itshaneli ezine ze-25Gbit/s. Zombini zingasetyenziswa kwiinethiwekhi ze-100G, kodwa ngeendlela ezahlukeneyo. I-QSFP28 inokufikelela kuthumelo lwe-100G ngeendlela ezintathu ezikhankanyiweyo apha ngasentla, kodwa i-SFP28 ixhomekeke kwiintambo zesantya esiphezulu ze-QSFP28 ukuya kwi-SFP28. Lo mfanekiso ulandelayo ubonisa uqhagamshelo oluthe ngqo lwe-100G QSFP28 ukuya kwi-4×SFP28 DAC.
I-QSFP kunye ne-QSFP28: Amanani ahlukeneyo, usetyenziso olwahlukileyo
Iimodyuli ze-QSFP+ kunye ne-QSFP28 optical zinobukhulu obufanayo kwaye zineendlela ezine ezidityanisiweyo zokudlulisa nokwamkela. Ukongeza, zombini iintsapho ze-QSFP+ kunye ne-QSFP28 zineemodyuli ze-optical kunye neentambo ze-DAC/AOC ezikhawulezayo, kodwa ngamanqanaba ahlukeneyo. Imodyuli ye-QSFP+ ixhasa izinga le-single-channel ye-40Gbit/s, kwaye i-QSFP+ DAC/AOC ixhasa izinga lokudlulisa le-4 x 10Gbit/s. Imodyuli ye-QSFP28 idlulisela idatha ngesantya se-100Gbit/s. I-QSFP28 DAC/AOC ixhasa i-4 x 25Gbit/s okanye i-2 x 50Gbit/s. Qaphela ukuba imodyuli ye-QSFP28 ayinakusetyenziswa kwiikhonkco zesebe le-10G. Nangona kunjalo, ukuba iswitshi enezibuko ze-QSFP28 ixhasa iimodyuli ze-QSFP+, ungafaka iimodyuli ze-QSFP+ kwiizibuko ze-QSFP28 ukuze usebenzise iikhonkco zesebe ze-4 x 10G.
