Ngā Taura SAS Tere-Tiketike: Ngā Hononga me te Arotau Tohu

Ngā Whakatakotoranga Pūmautanga Tohu

Ko ētahi o ngā tawhā matua o te pono o te tohu ko te ngaronga whakaurunga, te whakawhitiwhiti kōrero tata-pito me te tawhiti-pito, te ngaronga whakahoki, te whakapōturitanga piko i roto i ngā takirua rerekētanga, me te kaha mai i te aratau rerekētanga ki te aratau noa. Ahakoa he hononga tahi ēnei āhuatanga, ā, he awe tetahi ki tetahi, ka taea e tātou te whakaaro ki ia āhuatanga takitahi hei ako i tōna pānga matua.
Ngaronga Whakaurunga
Ko te ngaronga whakaurunga ko te whakaiti i te kaha o te tohu mai i te pito tuku ki te pito whiwhi o te taura, ā, he rite tonu ki te auau. Ka whakawhirinaki hoki te ngaronga whakaurunga ki te ine waea, e whakaaturia ana i te kauwhata whakaiti i raro nei. Mō ngā wāhanga ā-roto poto-whānui e whakamahi ana i ngā taura 30, 28-AWG rānei, me iti iho i te 2 dB/m te whakaiti o ngā taura kounga teitei i te 1.5 GHz. Mō ngā SAS 6 Gb/s o waho e whakamahi ana i ngā taura 10m, e taunakihia ana kia whakamahia ngā taura he ine waea toharite o te 24, he 13 dB anake te whakaiti i te 3 GHz. Mena kei te hiahia koe ki te whakatutuki i te tawhē tohu nui ake i ngā tere whakawhiti raraunga teitei ake, tohua ngā taura he iti ake te whakaiti i ngā auau teitei mō ngā taura roa ake, pērā i te SFF-8482 me te taura POWER, te SlimSAS SFF-8654 8i rānei.

Whakawhitiwhiti kōrero
Ko te whakawhitiwhiti kōrero e pā ana ki te nui o te pūngao e tukuna ana mai i tētahi tohu, takirua rerekē rānei ki tētahi atu tohu, takirua rerekē rānei. Mō ngā taura SAS, ki te kore e iti te whakawhitiwhiti kōrero tata-mutunga (NEXT), ka puta te nuinga o ngā raruraru hononga. Ko te ine i te NEXT ka mahia i tētahi pito o te taura anake, ā, ko te rahi o te pūngao e tukuna ana mai i te takirua tohu tuku putanga ki te takirua whiwhi tāuru. Ko te ine i te whakawhitiwhiti kōrero tawhiti-mutunga (FEXT) ka mahia mā te werohanga i tētahi tohu ki roto i te takirua tuku i tētahi pito o te taura, me te tirotiro i te nui o te pūngao e mau tonu ana i runga i te tohu tuku i tētahi pito o te taura. Ko te NEXT i roto i ngā wāhanga taura me ngā hononga ka puta i te nuinga o te wā nā te wehenga ngoikore o te takirua rerekē tohu, nā ngā putanga me ngā mono pea, te whenua kāore i oti, te whakahaere hē rānei o te rohe whakamutu taura. Me whakarite e ngā kaihoahoa pūnaha kua arohia e ngā kaiwhakaemi taura ēnei take e toru, pērā i ngā wāhanga pēnei i te MINI SAS HD SFF-8644, OCuLink SFF-8611 4i rānei.

Ko te 24, 26 me te 28 ngā pihinga ngaronga taura 100Ω noa.

Mō ngā huihuinga taura kounga teitei, ko te NEXT i inehia i runga anō i te "SFF-8410 – Whakatakotoranga mō te Whakamātautau Parahi HSS me ngā Whakaritenga Mahi" me iti iho i te 3%. Mō te tawhā-S, me nui ake te NEXT i te 28 dB.
Ngaronga whakahoki
Ka ine te ngaronga whakahoki i te rahi o te pūngao e whakaatahia ana mai i te pūnaha, i te taura rānei ina werohia he tohu. Ka heke te kaha o te tohu i te pito whiwhi o te taura nā tēnei pūngao whakaata, ā, ka arahi pea ki ngā raruraru pono o te tohu i te pito tuku, ka puta ai ngā raruraru wawao hikohiko mō te pūnaha me ngā kaihoahoa pūnaha.
Ko te korenga o te parenga i roto i ngā wāhanga taura te take o tēnei ngaronga whakahokinga. Mā te ata tirotiro i tēnei raruraru anake ka kore e rerekē te parenga ina haere te tohu mā roto i ngā kōhao, ngā mono, me ngā pito taura, kia iti ai te rerekētanga o te parenga. Ko te paerewa SAS-4 o nāianei ka whakahou i te uara parenga mai i te ±10Ω i roto i te SAS-2 ki te ±3Ω. Me pupuri e ngā taura kounga teitei te whakaritenga i roto i te manawanui o te 85, 100 ± 3Ω rānei, pērā i te SFF-8639 me te Taura SATA 15P, te Taura MCIO 74 Pin rānei.

Te whakapōturitanga o te piko
I roto i ngā taura SAS, e rua ngā momo whakapōturitanga piko: i waenga i ngā takirua rerekētanga me roto i ngā takirua rerekētanga (ariā pono tohu – tohu rerekētanga). I roto i te ariā, ki te whakaurua ngā tohu maha i te wā kotahi ki tētahi pito o te taura, me tae atu ki tētahi pito i te wā kotahi. Ki te kore ēnei tohu e tae mai i te wā kotahi, ka kiia tēnei āhuatanga ko te whakapōturitanga piko taura, ko te whakapōturitanga whakaroa-piko rānei. Mō ngā takirua rerekētanga, ko te whakapōturitanga piko i roto i te takirua rerekētanga ko te whakaroa i waenga i ngā kaiarataki e rua o te takirua rerekētanga, ko te whakapōturitanga piko i waenga i ngā takirua rerekētanga ko te whakaroa i waenga i ngā huinga takirua rerekētanga e rua. Ka taea e te whakapōturitanga piko nui ake i roto i te takirua rerekētanga te whakararu i te taurite rerekētanga o te tohu tuku, te whakaiti i te kaha o te tohu, te whakanui ake i te wiri wā, me te whakaputa raruraru pokanoa hikohiko. Mō ngā taura kounga teitei, me iti iho i te 10 ps te whakapōturitanga piko i roto i te takirua rerekētanga, pērā i te SFF-8654 8i ki te SFF-8643, te taura Whakaurunga Ārai-hē rānei.
Te pokanoa hikohiko
He maha ngā take o ngā raruraru whakararuraru hikohiko i roto i ngā taura: te ārai ngoikore, te kore rānei o te ārai, te tikanga whenua hē, ngā tohu rerekētanga kore taurite, me te kore taurite o te aukati he take anō hoki. Mō ngā taura o waho, ko te ārai me te whenua pea ngā mea nui e rua hei aro atu, pērā i te SFF-8087 me te mata whero, te taura whenua mata Cooper rānei.
I te nuinga o te wā, ko te parenga o waho, o te ārai whakararuraru hikohiko rānei, me whakamahi i tētahi parenga takirua o te pepa whakarewa me te paparanga whiri, me te hipoki whānui o te 85%. I taua wā anō, me hono tēnei parenga ki te koti o waho o te hononga, me te hononga katoa 360°. Me wehe te parenga o ngā takirua rerekētanga takitahi mai i te parenga o waho, ā, me mutu ā rātou raina tātari i te tohu pūnaha, i te whenua DC rānei hei whakarite i te mana ārai kotahi mō ngā wāhanga hononga me te taura, pērā i te taura hononga ārai-tapahi SFF-8654 8i Full Wrap, te taura hononga ārai-koropiko rānei.
