SFP
Ka taea te mārama ko te SFP he putanga whakapai ake o te GBIC. Ko tōna rahinga he haurua noa iho o te rahinga o te kōwae GBIC, e tino whakanui ana i te kiato o te tauranga o ngā taputapu whatunga. Hei tāpiri, ko ngā tere whakawhiti raraunga o te SFP kei waenga i te 100Mbps ki te 4Gbps.
SFP+
Ko te SFP+ he putanga whakarei ake o te SFP e tautoko ana i te hongere muka 8Gbit/s, te 10G Ethernet me te OTU2, te paerewa whatunga tuku whatu. Hei tāpiri, ka taea e ngā taura tika SFP+ (arā, ngā taura tere-teitei SFP+ DAC me ngā taura whatu hohe AOC) te hono i ngā tauranga SFP+ e rua me te kore e tāpiri i ētahi atu kōwae me ngā taura whatu (ngā taura whatunga, ngā peke muka rānei), he kōwhiringa pai tēnei mō te hononga tika i waenga i ngā pana whatunga tawhiti-poto e rua e tata ana.
SFP28
He putanga whakarei ake te SFP28 o te SFP+, he rite te rahi ki te SFP+ engari ka taea te tautoko i ngā tere hongere kotahi o te 25Gb/s. He otinga whai hua te SFP28 mō te whakapai ake i ngā whatunga 10G-25G-100G hei whakatutuki i ngā hiahia e tipu haere ana o ngā whatunga pokapū raraunga o te whakatupuranga e whai ake nei.
QSFP+
He putanga hou te QSFP+ o te QSFP. Kāore i rite ki te QSFP+, e tautoko ana i ngā hongere 4 gbit/s i te tere o te 1Gbit/s, ka tautoko te QSFP+ i ngā hongere 4 x 10Gbit/s i te tere o te 40Gbps. Ki te whakatauritea ki te SFP+, e whā ngā wā teitei ake te tere tuku o te QSFP+ i tērā o te SFP+. Ka taea te whakamahi tika i te QSFP+ ina whakatinanahia he whatunga 40G, ā, ka penapenahia te utu me te whakapiki ake i te kiato o te tauranga.
QSFP28
E whā ngā hongere tohu rerekētanga tere-teitei e tukuna ana e te QSFP28. Ko te tere tuku o ia hongere he rerekē mai i te 25Gbps ki te 40Gbps, ka taea te whakatutuki i ngā whakaritenga o te Ethernet 100 gbit/s (4 x 25Gbps) me ngā tono EDR InfiniBand. He maha ngā momo hua QSFP28, ā, he rerekē ngā momo tuku 100 Gbit/s e whakamahia ana, pērā i te hononga tika 100 Gbit/s, te hurihanga 100 Gbit/s ki ngā hononga peka e whā 25 Gbit/s, te hurihanga 100 Gbit/s rānei ki ngā hononga peka e rua 50 Gbit/s.
Ngā rerekētanga me ngā āhuatanga ōrite o SFP, SFP+, SFP28, QSFP+, QSFP28
I muri i te māramatanga ki te SFP, SFP+, SFP28, QSFP+, QSFP28, ka whakamāramahia ngā āhuatanga ōrite me ngā āhuatanga rerekē i waenganui i ngā mea e rua i muri mai.

SFP me te SFP+: He rite te rahi, he rerekē ngā tere me te hototahitanga
He rite tonu te rahi me te āhua o ngā kōwae SFP me SFP+, nō reira ka taea e ngā kaihanga taputapu te whakamahi i te hoahoa ā-tinana o te SFP i runga i ngā pana me ngā tauranga SFP+. Nā te rahi ōrite, he maha ngā kaihoko e whakamahi ana i ngā kōwae SFP i runga i ngā tauranga SFP+ o ngā pana. Ka taea tēnei mahi, engari ka whakaitihia te tere ki te 1Gbit/s. Hei tāpiri, kaua e whakamahia te kōwae SFP+ i roto i te mokamoka SFP. Ki te kore, ka pakaru pea te tauranga, te kōwae rānei. Haunga te hototahitanga, he rerekē ngā tere tuku me ngā paerewa o te SFP me te SFP+. Ka taea e te SFP+ te tuku i te mōrahi o te 4Gbit/s me te mōrahi o te 10Gbit/s. Ko te SFP e hangai ana ki te kawa SFF-8472, ko te SFP+ e hangai ana ki ngā kawa SFF-8431 me te SFF-8432.
SFP28 me te SFP+: Ka taea te hono i te kōwae whatu SFP28 ki te tauranga SFP+
E ai ki te kōrero i runga ake nei, ko te SFP28 he putanga whakapai ake o te SFP+ me te rahi ōrite engari he rerekē ngā tere tuku. Ko te tere tuku o te SFP+ he 10Gbit/s, ā, ko te SFP28 he 25Gbit/s. Mena ka whakauruhia te kōwae whatu SFP+ ki te tauranga SFP28, ko te tere tuku hononga he 10Gbit/s, ā, ko te ritenga kē. Hei tāpiri, he nui ake te whānui o te taura parahi e hono tika ana ki te SFP28, ā, he iti ake te ngaronga i tērā i te taura parahi e hono tika ana ki te SFP+.
SFP28 me QSFP28: he rerekē ngā paerewa kawa
Ahakoa kei a SFP28 me QSFP28 te nama "28", he rerekē ngā rahi e rua i te paerewa kawa. Ka tautoko te SFP28 i te hongere kotahi 25Gbit/s, ā, ka tautoko te QSFP28 i ngā hongere e whā 25Gbit/s. Ka taea te whakamahi i ngā mea e rua i runga i ngā whatunga 100G, engari i roto i ngā huarahi rerekē. Ka taea e te QSFP28 te whakatutuki i te tuku 100G mā roto i ngā tikanga e toru kua whakahuatia i runga ake nei, engari ka whakawhirinaki te SFP28 ki ngā taura tere-teitei o te peka QSFP28 ki te SFP28. E whakaatu ana te pikitia e whai ake nei i te hononga tika o te 100G QSFP28 ki te 4×SFP28 DAC.
QSFP me QSFP28: Ngā reiti rerekē, ngā tono rerekē
He rite te rahi o ngā kōwae whatu QSFP+ me QSFP28, ā, e whā ngā hongere tuku me te whiwhi kua whakauruhia. Hei tāpiri, he kōwae whatu me ngā taura tere-teitei DAC/AOC kei ngā whānau QSFP+ me QSFP28, engari he rerekē ngā tere. Ka tautoko te kōwae QSFP+ i te tere hongere kotahi 40Gbit/s, ā, ka tautoko te QSFP+ DAC/AOC i te tere tuku 4 x 10Gbit/s. Ka whakawhiti raraunga te kōwae QSFP28 i te tere o te 100Gbit/s. Ka tautoko te QSFP28 DAC/AOC i te 4 x 25Gbit/s, 2 x 50Gbit/s rānei. Kia mahara kāore e taea te whakamahi i te kōwae QSFP28 mō ngā hononga peka 10G. Heoi, ki te tautoko te pana me ngā tauranga QSFP28 i ngā kōwae QSFP+, ka taea e koe te whakauru i ngā kōwae QSFP+ ki ngā tauranga QSFP28 hei whakatinana i ngā hononga peka 4 x 10G.
