ʻO DAC Copper a i ʻole Fiber?
Hana ʻia nā kaula DAC mai ka Twinax copper coaxial i pale ʻia a ua lako ʻia me nā modules ma kēlā me kēia ʻaoʻao i pili i nā awa paʻa.ʻAʻole hiki ke wehe ʻia nā modula mai ke kaula.No laila, hana ʻia nā kaula DAC āpau i kahi lōʻihi paʻa.ʻO ke kaula keleawe kiʻekiʻe ka hana attenuation maikaʻi loa, haʻahaʻa haʻahaʻa, a me ka anti-interference i ka hoʻouna ʻana i ka broadband kiʻekiʻe.
He aha ka Twinax Cable i hoʻohana ʻia no?
Hiki ke hoʻohana nui ʻia ke kaula Twinax i hoʻopili pololei ʻia i ka pilina kikowaena data e like me nā mea mālama SATA, nā ʻōnaehana RADI, nā mea hoʻokele kumu, nā hoʻololi kumu, nā kikowaena no 10G/40G/100G Ethernet, a me InfiniBand.ʻO ka ʻōlelo maʻamau, hāʻawi kēia mea hoʻopili pololei i ke kaula keleawe i kahi hopena maikaʻi a kiʻekiʻe hoʻi no kēia mau kūlana:
• ʻO luna o ka Rack(ToR)/Adjacent Rack - ʻO ka passive a i ʻole ka hana DAC uwea kūpono loa no nā hana pōkole ʻo ToR a i ʻole rack-to-rack me nā kumukūʻai kūpono.
• Ma waena o ka Lālani - He hopena maikaʻi paha nā DAC Active i kēia noi, ʻoiai ʻoi aku ka lōʻihi o ka hoʻouna ʻana ma lalo o 15m.
• Hoʻopau o ka Lālani - He kūpono nā kaula DAC no ka hoʻopau ʻana i nā kiʻina lālani i ka lōʻihi o ka mamao i loko o ka palena 15 mika.
He aha ka ʻokoʻa ma waena o nā kelepona DAC Active a me Passive?
ʻO ka ʻokoʻa nui ma waena o kahi kaula DAC ikaika a me kahi kaula DAC passive ʻo ia ka hana ʻana o ka hōʻailona hōʻailona a i ʻole.Inā loaʻa kahi mea uila no ka hōʻailona hōʻailona i ke kaula, he "DAC Active".Inā ʻaʻole, he "DAC Passive", no ka mea, ʻaʻole ia e pili i ka uila no ka hōʻailona hōʻailona.Ma waho aʻe o ka ʻāpana o loko, ʻokoʻa nā kaula DAC ikaika a passive mai kekahi i kekahi i ka lōʻihi o ka loulou.Hoʻouna ke kelepona DAC Twinax passive i ka hōʻailona Ethernet ma kahi lōʻihi pōkole (0.5 m-5 m), ʻoiai ke kākoʻo nei ke kaula DAC Twinax ikaika i kahi mamao hoʻouna o 5 m-10 m no kahi hōʻailona Ethernet.
