He aha ngā taputapu e hiahiatia ana mō te hanga me te whakamātautau i ngā kōwae whatu 800G?
Te whakamātautau i te 800Gngā kōwae whatukei roto ko te whakamātautau mahi hopu me te whakamātautau mahi tuku. Ko te rārangi taputapu matua me te arorau e whai ake nei:
1. Ngā taputapu whakamātautau
Papa kawe 1.1MCB
Whirihorahia kia rua ngā papa kawe MCB hei whakanoho i te waeine DUT me te waeine paerewa. Ka whakaurua te waeine whatu ki roto i te papa kawe, ā, ka honoa ki te mita waehere hapa mā te taura RF tere-teitei. Ka taea e ngā papa kawe e rua te whakarite i te motuhaketanga o te whakamātautau RX me te whakamātautau TX. Mena kei te whakamahi i te whakamātautau whakamuri, kotahi anake te papa kawe e hiahiatia ana. Me whai ara whatu 8T8R te waeine whatu 800G, e rite ana ki te whakaritenga o te 16 takirua tohu rerekētanga mō te Gold Finger, arā, 32 ngā taura RF/papa kawe.
1.2 Ngā Taputapu Whakahaere Pāmahana
Ko ngā papa kawe MCB he mea whakarite ki ngā taputapu pāmahana me ngā taputapu kimi hei tautoko i te mahi whakamātautau i ngā pāmahana rerekē. Ko ngā taputapu whakahaere pāmahana ka utaina ki runga i te papa kawe MCB o te DUT. Mā te whakauru i te mana whakahaere pāmahana ki runga i te papa kawe MCB ka taea te whakahaere i ngā taputapu.
1.3 Kaitātari waehere hapa
Whirihorahia kia rua ngā whakamātautau hapa moka 800G hei tuku i ngā raupapa PRBS me ngā whakamātautau puku RX me TX. Mena ka tautokohia e te kōwae whatu paerewa te raupapa PRBS, ka taea e ia te tiaki i te kotahi te kite hapa moka, ā, ka taea te whakamahi i te rorohiko o runga hei whakahau i te kōwae whatu paerewa hei tuku i te raupapa whakamātautau. Whakamātautau Puku RX (whakamātautau hapa moka): Waihangahia he raupapa whakamātautau, whiwhi i te raupapa whakahoki, ka whakataurite i te hapa i waenga i te tuku me te kaiwhiwhi, arā, te hapa moka. Whakamātautau Puku TX (whakamātautau hoahoa kanohi): Waihangahia he raupapa whakamātautau mō te DUT, ā, ka tukuna e te DUT te mārama e ai ki tēnei raupapa. Mā te whakaurunga ā-roto o te papa kawe MCB me ngā taputapu whakahaere pāmahana ki roto i te tātari waehere hapa ka taea te whakahaere ake i te taputapu.
Taputapu Karaka 1.4CDR
Ka tukuna te tohu whatu i ia wā, ā, ka tautuhia e te CDR te taha o tēnei wā wā mai i te tohu whatu.
1.5 Oscilloscope
E ai ki te tohu wā i homai e te CDR, ka tāpirihia ngā raraunga tohu whatu i ia wā hei hanga i tētahi hoahoa kanohi. Mena ka tautoko te oscilloscope i ngā tāurunga e 4 me te whakamātautau 800G, ka hiahiatia kia rua ngā waeine. He nui ake te utu, ki te hiahia koe ki te penapena moni, ka taea e koe te whakamahi i tētahi pana rama hei whakawhiti.
1.6Pana whatu
Whakawhitihia te ara whatu i waenga i te whakamātautau hoahoa kanohi me te whakamātautau mana.
1.7Mita mana whatu
Ine i te mana whatu putanga, 8 ngā hongere. Ka taea te whakauru i te mita mana whatu ki roto i te pana whatu, hei whakahaere i ngā taputapu.
Pūnaha hiko 1.8 DC
Whakaratohia he hiko DC pumau ki te papa kawe MCB.
2、 Te whakamātautau i te arorau hanganga pūnaha
2.1. Whakamātautau mahi whiwhinga RX (tere hapa moka, aro)
Rere tohu: Kaitātari waehere hapa 2 → Kōwae whatu paerewa → Kaiwhakaiti whatu → DUT → Kaitātari waehere hapa 1
Ngā taputapu matua: te whakaiti i te hihi o te rama (e whakamahia ana mō te matawai i ngā pū hiko), te waeine hihi paerewa (e whakamahia ana hei pūtake mārama).
Kaupapa: Hei ine i te tere hapa moka o te DUT i ngā mana whatu rerekē mā te whakarerekē i te nui o te whakaiti.
2.2. Whakamātautau mahi tukunga TX (kaupapa kanohi, mana whatu)
Rere tohu: Kaitātari waehere hapa 1 → DUT → Pana whatu → (mita mana/orotirotiro+CDR)
Ngā taputapu matua: Pana whatu (pana ara), CDR (whakaora karaka, mō ngā tohu PAM4).
Kaupapa: Hei manatoko i te mana o te mārama e tukuna ana me te kounga o te tohu (me whakaatu te hoahoa kanohi i ngā "kanohi" e toru o PAM4).
3, Ngā mea matua o te whirihoranga motuhake mō te whakamātautau 800G
Rahinga hongere: E 8 ngā hongere (8T8R) e whakamahia ana e te 800G, ā, me rite ngā maihao whakarewa o te papa kawe MCB ki te 16 takirua o ngā tohu rerekētanga (32 taura RF).
Momo tohu: Mō te whakarerekētanga PAM4, me hono te oscilloscope ki ngā taputapu CDR hei hopu tika i te hoahoa kanohi.
Otinga māmā: Ka taea e te taputapu kite hapa te whakauru i ngā mahi MCB me te whakahaere pāmahana. Ka taea te whakauru i te pana whatu ki te mita mana whatu. Mena ka whakamahia te whakamātautau whakamuri porowhita (kohikohi-ā-ringa DUT), ka taea te whakaiti i te papa kawe MCB kotahi me te waeine paerewa, engari he iti pea ngā tūemi whakamātautau.
4. Whakamārama i ngā kupu matua
PRBS: He raupapatanga rūpahu matapōkere, e whakatauira ana i te haere o ngā raraunga tūturu.
MCB: Poari kawe hanganga ture mō te waeine, taputapu whakamātautau.
CDR: Te whakaora raraunga karaka, te tango karaka mai i ngā tohu whatu.
Kauwhata kanohi PAM4: te whakarerekētanga kaha o te pāorooro taumata-whā, e whakaatu ana te kauwhata kanohi i ngā taahiraa e whā (ngā whakatuwheratanga kanohi e toru)
