He aha te QSFP?
Āhua-Iti Ka taea te Mono (SFP)He hōputu kōwae atanga whatunga kiato, ka taea te mono-wera e whakamahia ana mō ngā tono whakawhitiwhiti kōrero me ngā whakawhitiwhiti raraunga. Ko te atanga SFP i runga i ngā taputapu whatunga he mokowā mō tētahi taputapu whakawhiti pāpāho motuhake, pērā i te taura muka-whatu, i te taura parahi rānei.[1] Ko te painga o te whakamahi i ngā SFP ki te whakataurite ki ngā atanga pumau (hei tauira, ngā hononga kōwae i roto i ngā pana Ethernet) ko te taea o ngā tauranga takitahi te whakauru i ngā momo taputapu whakawhiti rerekē e hiahiatia ana, ko te nuinga kei roto ko ngā pito raina whatu, ngā kāri whatunga, ngā pana me ngā pouara.
Ko te QSFP, arā, ko te Quad Small Form-factor Pluggable,kohe momo waeine whakawhiti raraunga e whakamahia ana mō te tuku raraunga tere-teitei i roto i ngā taputapu whatunga, inā koa i roto i ngā pokapū raraunga me ngā taiao rorohiko mahi-teitei.. Kua hangaia hei tautoko i ngā hongere maha (e whā te nuinga) ā, ka taea te whakahaere i ngā tere raraunga mai i te 10 Gbps ki te 400 Gbps, i runga i te momo kōwae motuhake.
Te whanaketanga o te QSFP:
Kua whanake haere te paerewa QSFP i roto i te wā, me ngā putanga hou pēnei i te QSFP+, QSFP28, QSFP56, me te QSFP-DD (Double Density) e tuku ana i ngā tere raraunga me ngā āheinga kua piki ake. Ka hangaia ēnei putanga hou i runga i te hoahoa QSFP taketake hei whakatutuki i ngā tono e tipu haere ana mō te whānui o te hononga me ngā tere tere ake i roto i ngā whatunga hou.
Ngā Āhuatanga Matua o te QSFP:
- Teitei-Kōkī:
He mea hanga ngā kōwae QSFP kia kiato, kia taea ai te maha o ngā hononga i roto i tētahi wāhi iti.
- Ka taea te mono wera:
Ka taea te whakauru me te tango mai i tētahi pūrere i te wā e whakakā ana, me te kore e whakararuraru i te whatunga.
- Ngā Hongere Maha:
E whā ngā hongere o ngā kōwae QSFP, ā, e taea ana e ia hongere te tuku raraunga, e āhei ai te whakapiki ake i te whānui o te hononga me ngā tere raraunga.
- Ngā Reiti Raraunga Rerekē:
He rerekē ngā momo QSFP, pērā i te QSFP+, QSFP28, QSFP56, me te QSFP-DD, e tautoko ana i ngā tere rerekē mai i te 40Gbps ki te 400Gbps me tua atu.
- Ngā Taupānga Maha:
E whakamahia ana ngā kōwae QSFP i roto i te whānuitanga o ngā tono, tae atu ki ngā hononga pokapū raraunga, ngā rorohiko mahi-teitei, me ngā whatunga whakawhitiwhiti kōrero.
- Ngā Kōwhiringa Parahi me te Muka Whatu:
Ka taea te whakamahi i ngā kōwae QSFP me ngā taura parahi (Direct Attach Cables, DAC rānei) me ngā taura muka whatu.
