Kōwae Whatu CFP/CFP2/CFP4

Ko te CFP MSA te paerewa ahumahi tuatahi e tautoko ana i ngā whakawhiti whatu Ethernet 40 me te 100Gbe. Ko te kawa maha-pūtake CFP he tautuhi i tētahi whakatakotoranga takai mō ngā kōwae whatu whakawhiti-wera hei whakatairanga i ngā tono 40 me te 100Gbit/s, tae atu ki ngā tono Ethernet tere-teitei o te whakatupuranga e whai ake nei (40 me te 100GbE). Ko ngā momo kete o ngā kōwae whatu raupapa CFP 100G ko te CFP, CFP2, me te CFP4.

Whakataki o te Momo Whatu CFP/CFP2/CFP4

Ko te rahi o te kōwae whatu CFP te mea nui rawa atu, ko te kōwae whatu CFP2 he haurua o te CFP, ko te kōwae whatu CFP4 he hauwhā o te CFP, ā, ko te momo kete o te kōwae whatu QSFP28 he iti iho i te kōwae whatu CFP4. Ko te rōrahi o ēnei kōwae e toru, e whakaaturia ana i raro nei. Ko te mea hei whakamahara, kāore e taea te whakamahi tauwhitiwhiti i ngā kōwae whatu CFP/CFP2/CFP4, engari ka taea te whakamahi i te wā kotahi i roto i te pūnaha kotahi.

Ka tautokohia e ngā kōwae whatu CFP te tuku i runga i ngā muka whatu aratau-kotahi me te aratau-maha me ngā tere maha, ngā kawa, me ngā roa hononga e hiahiatia ana, tae atu ki ngā atanga katoa e pā ana ki te reo ā-tinana (PMD) kei roto i te paerewa IEEE802.3ba.

Kua hangaia te kōwae whatu CFP i runga i te atanga kōwae whatu mono iti (SFP), he rahi ake, ā, e tautoko ana i te tuku raraunga 100 Gbps. Ka taea e te kōwae whatu CFP te tautoko i tētahi tohu 100G kotahi, OTU4, tētahi, neke atu rānei ngā tohu 40G, OTU3, STM-256/OC-768 rānei.

He maha ngā wā ka whakamahia te 100G CFP2 hei hononga hononga Ethernet 100G, he nui ake te pai o te tuku i ngā kōwae whatu CFP, ā, nā te iti o te rahi e pai ai mō ngā waea kiato teitei ake.

He rite tonu te tere o te kōwae whatu CFP4 100G ki te kōwae whatu CFP/CFP2. Kua tino pai ake te pai o te tuku, engari kua whakaitihia te whakapaunga hiko, ā, he iti iho te utu i te CFP2. Nō reira, he nui ngā painga o te kōwae whatu CFP4. Kōrerohia ngā painga o ngā kōwae whatu CFP4.

Ngā Painga o te Kōwae Whatu CFP4

1. Te tere tuku hiko teitei ake: I eke te kōwae whatu CFP 100G o mua ki te tere tuku hiko o te 100G mā roto i ngā hongere 10G e 10, ko te kōwae whatu CFP4 100G o nāianei ka eke ki te tere tuku hiko 100G mā roto i ngā hongere 25G e 4, nō reira he teitei ake te tere tuku hiko. He kaha ake te pumau.

2. He iti ake te rōrahi: Ko te rōrahi o te kōwae whatu CFP4 he hauwhā o te rōrahi o te CFP, koinei te kōwae whatu iti rawa i roto i te raupapa CFP o ngā kōwae whatu.

3. Te whakaurunga mōrahi teitei ake: Ko te taumata whakaurunga o te CFP2 e rua ngā wā i tō te CFP, ā, ko te taumata whakaurunga o te CFP4 e whā ngā wā i tō te CFP.

4. He iti ake te whakapaunga hiko me te utu: Kua tino pai ake te whai huatanga o te tuku o ngā kōwae whatu CFP4, engari kua whakaitihia te whakapaunga hiko, ā, he iti iho hoki te utu pūnaha i tō te CFP2.

Hei whakarāpopototanga

He tino nui te kōwae whatu CFP o te whakatupuranga tuatahi, ā, kātahi ka puta mai ngā kōwae whatu CFP2 me CFP4. I roto i ēnei, ko te kōwae whatu CFP4 te whakatupuranga hou o ngā kōwae whatu 100G, ā, ko tōna whānui he 1/4 noa iho o te kōwae whatu CFP. He iti ake te momo takai o te kōwae whatu QSFP28 i tērā o te kōwae whatu CFP4, ko te tikanga he nui ake te kiato o te putanga o te kōwae whatu QSFP28 i runga i te pana.

Ahakoa he maha ngā painga o te kōwae whatu QSFP28, he kotahi noa iho tēnei o ngā otinga maha mō ngā whatunga 100G. Mō ngā tono motuhake pēnei i ngā pokapū raraunga me ngā rūma whakawhiti, ko te whiriwhiri i te mea tika te otinga pai rawa atu.

Ka whakaratohia e HUANET ngā momo 100G CFP/CFP2/CFP4 me te 100G QSFP28 katoa me te kounga teitei me te hototahi pai i te utu iti rawa.
