Kupu Whakataki
Ngā kaiwhiwhi muka whatume ngā kaiwhiwhi waeine whatu he taputapu matua mō ngā whakawhitiwhiti kōrero whatu, engari he rerekē ngā mahi, ngā horopaki tono me ngā āhuatanga.
1. Whakawhitiwhiti muka whatu:
Ko te taputapu whakawhiti muka whatu he taputapu e huri ana i ngā tohu whatu hei tohu hiko (te pito tuku) e huri ana rānei i ngā tohu hiko hei tohu whatu (te pito whiwhi). Ka whakauruhia e ngā taputapu whakawhiti muka whatu ngā wāhanga pēnei i ngā kōwae tuku taiaho, ngā kaitahuri whakaahua-hiko, me ngā taraiwa ara iahiko. I te nuinga o te wā ka whakauruhia ēnei ki roto i ngā mokowā kōwae whatu o ngā taputapu whatunga (pēnei i ngā pana, ngā pouara, ngā tūmau, me ētahi atu) i roto i tētahi kete paerewa. Ka whakamahia ngā taputapu whakawhiti muka whatu hei whakarato i te hurihanga tohu i waenga i te mārama me te hiko, ā, ka whai wāhi hoki ki te tuku tohu i te wā e tuku raraunga ana.
2. Pūwhakawhiti mōrahi whatu:
He taputapu whatu ā-pūrere te taputapu whakawhiti mōrahi whatu e whakauru ana i te taputapu whakawhiti muka whatu. Ko te taputapu whakawhiti mōrahi whatu he atanga muka whatu, he mōrahi tuku tohu whatu (kaituku), me he mōrahi whiwhi tohu whatu (kaiwhiwhi). He rahi paerewa me te atanga paerewa te taputapu whakawhiti mōrahi whatu, ā, ka taea te whakauru ki roto i te mokowā mōrahi whatu i roto i ngā taputapu whatunga pēnei i ngā pana me ngā pouara. Ko te taputapu whakawhiti mōrahi whatu he mea whakarato i te nuinga o te wā hei mōrahi motuhake hei ngāwari ki te whakakapi, ki te tiaki, me te whakapai ake.
Ngā Painga o te Pūwhakawhiti muka whatu me te kōwae whatu
1. Whakawhitiwhiti muka whatu
Te tūnga mahi
Whakamahia mō te hurihanga tohu hiko-whakaahua (pērā i te tauranga hiko Ethernet ki te tauranga whatu), te whakaoti rapanga hononga o ngā momo pāpāho rerekē (taura parahi ↔ muka whatu).
He taputapu motuhake te nuinga o te wā, e hiahiatia ana he pūtake hiko o waho, ā, e whakarato ana i te 1~2 ngā tauranga whatu me ngā tauranga hiko (pēnei i te RJ45).
Te horopaki tono
Whakaroahia te tawhiti tuku: whakakapia te taura parahi parakore, pakaruhia te rohe 100-mita (ka taea e te muka whatu aratau-kotahi te neke atu i te 20km).
Whakawhanui whatunga: hono i ngā wāhanga whatunga o ngā pāpāho rerekē (pēnei i te whatunga o te kāmpus, te pūnaha aroturuki).
Taiao ahumahi: urutau ki ngā āhuatanga pāmahana teitei me ngā āhuatanga pokanoa hikohiko kaha (tauira taumata ahumahi).
Ngā Painga
Monokia, ā, purei: kāore he whirihoranga e hiahiatia ana, he pai mō ngā whatunga iti, mō te urunga taha rānei.
Utu iti: he pai mō te tere iti me te tawhiti poto (pērā i te 100M/1G, muka whatu maha-aratau).
Ngāwari: tautoko i ngā momo muka maha (aratau-kotahi/aratau-maha) me ngā roangaru (850nm/1310nm/1550nm).
Ngā Here
Mahi iti: Kāore e tautoko i ngā tere teitei (pērā i runga ake i te 100G) me ngā kawa uaua.
Rahi nui: Ka noho wāhi ngā taputapu takitahi.
2. Wāhanga Whatu
Te Tūnga Mahi
Mā ngā atanga whatu (pērā i ngā mokamoka SFP me QSFP) kua whakauruhia ki roto i ngā pana, ngā pouara me ētahi atu taputapu ka whakaoti tika i te tahuritanga tohu whatu-hiko.
Tautoko i ngā kawa tere-teitei me ngā kawa maha-tikanga (pērā i te Ethernet, Fibre Channel, CPRI).
Ngā horopaki tono
Pokapū raraunga: hononga tere-teitei, kiato-rahi (pērā i ngā kōwae whatu 40G/100G/400G).
Whatunga kawe 5G: ngā whakaritenga tere-teitei me te iti-roa mō te fronthaul me te midhaul (pērā i ngā kōwae whatu hina 25G/50G).
Whatunga matua: te tuku tawhiti (pērā i ngā kōwae DWDM me ngā taputapu OTN).
Ngā Painga
Teitei te mahi: e tautoko ana i ngā tere mai i te 1G ki te 800G, e tutuki ana i ngā paerewa uaua pēnei i te SDH me te OTN.
Whakawhiti-wera: whakakapinga ngāwari (pērā i ngā kōwae SFP+) kia māmā ake ai te whakapai ake me te tiaki.
Hoahoa kiato: mono tika ki te taputapu hei penapena wāhi.
Ngā Here
Kei runga i te pūrere manaaki: me hototahi ki te atanga me te kawa o te pana/pouara.
Te utu nui ake: He nui te utu mō ngā kōwae tere-rahi (pērā i ngā kōwae whatu mārama).
Hei whakamutunga
Ngā whakawhiti muka whatuhe taputapu e huri ana i ngā tohu whatu hei tohu hiko, i ngā tohu hiko rānei hei tohu whatu, ā, he maha ngā wā ka whakaurua ki roto i ngā mokowā kōwae whatu;
Ko ngā kaiwhakawhitiwhiti kōwae whatu he taputapu whatu kōwae e whakauru ana i ngā kaiwhakawhitiwhiti muka whatu, ko te nuinga o te wā he atanga muka whatu, he kaiwhakawhiti, me he kaiwhiwhi. He hoahoa kōwae motuhake. Ko ngā kaiwhakawhitiwhiti kōwae whatu he momo takai me te momo tono o ngā kaiwhakawhitiwhiti muka whatu e whakamahia ana hei whakahaere i te whakaurunga me te whakahaere i ngā taputapu whakawhitiwhiti whatu.
