DAC Copper kana Fiber?

DAC Mhangura kana Fiber?
Tambo dzeDAC dzakagadzirwa kubva pakadzivirirwa Twinax coaxial yemhangura uye fekitori inoshongedzerwa nemamodule pane chero kumagumo akabatana kune yakagadziriswa ports.Iyo modules haigone kubviswa kubva kune tambo.Naizvozvo, tambo dzese dzeDAC dzinogadzirwa nehurefu hwakatarwa.Iyo yakakwirira-inomhanya tambo yemhangura ine yakanakisa attenuation performance, yakaderera latency, uye anti-kupindira mune yakakwirira-frequency Broadband kutapurirana.

Chii chinonzi Twinax Cable Inoshandiswa?
Yakananga yakasungirirwa Twinax tambo inogona kushandiswa zvakanyanya mu data center interconnection yakadai seSATA storage devices, RADI systems, core routers, core switches, maseva e10G/40G/100G Ethernet, uye InfiniBand.Kazhinji kutaura, iyi yakananga tambo yemhangura inopa inodhura-inoshanda uye yepamusoro-inoshanda mhinduro kune anotevera mamiriro:
• Pamusoro peRack(ToR)/Adjacent Rack - Ingave passive kana inoshanda yeDAC tambo yakanakira kupfupika kweToR kana rack-to-rack mashandiro ane mari isingadhuri.
• Pakati peRow - Active DACs inogona kunge iri mhinduro iri nani muchirongwa ichi, chero kureba kwekufambisa kuri pasi pe15m.
• Kupera kweRow - tambo dzeDAC dzakanakira kupera kwemitsara yezvivakwa chero kureba kuri mukati megumi neshanu muganhu.

Ndeupi Musiyano Uripo Pakati PeAnoshanda uye Passive DAC Cables?
Musiyano mukuru pakati peiyo inoshanda yeDAC tambo uye passive DAC tambo ndeyekuti iyo chiratidzo chekugadzirisa chaitwa here kana kuti kwete.Kana paine chikamu chemagetsi chekugadzirisa chiratidzo mutambo, i "Active DAC".Kana zvisina kudaro, i "Passive DAC", sezvo isingashandisi zvemagetsi pakugadzirisa zviratidzo.Kunze kwechikamu chemukati, tambo dzinoshanda uye dzisiri dzeDAC zvakare dzinosiyana kubva kune imwe neimwe mukureba kwekubatanidza.A passive DAC Twinax tambo inotumira chiratidzo cheEthernet pamusoro pehurefu hupfupi (0.5 m-5 m), nepo inoshanda yeDAC Twinax tambo inotsigira chinhambwe chekufambisa che5 m-10 m yeEthernet chiratidzo.
