Ingabe i-DAC Copper noma Fiber?

Ingabe i-DAC Copper noma Fiber?
Izintambo ze-DAC zenziwe nge-Twinnax copper coaxial evikelekile futhi afakwe embonini ngamamojula anoma yiluphi uhlangothi axhunywe kumachweba angashintshi.Amamojula awakwazi ukususwa kukhebuli.Ngakho-ke, zonke izintambo ze-DAC zikhiqizwa ngobude obunqunyiwe.Ikhebula le-copper elinesivinini esikhulu linokusebenza okuhle kakhulu kokunciphisa, ukubambezeleka okuphansi, kanye nokuphikisana nokuphazamiseka ekudlulisweni kwe-broadband ye-high-frequency.

Ikhebula le-Twinax lisetshenziselwa ini?
Ikhebula le-Twinax elinamathiselwe ngqo lingasetshenziswa kakhulu ekuxhumekeni kwesikhungo sedatha njengamadivayisi esitoreji se-SATA, izinhlelo ze-RADI, amarutha ayinhloko, amaswishi ayinhloko, amaseva e-10G/40G/100G Ethernet, ne-InfiniBand.Ngokuvamile, le ntambo yethusi yokunamathisela ngokuqondile inikeza isisombululo esingabizi kakhulu nesisebenza kakhulu kulezi zimo ezilandelayo:
• I-top of Rack(ToR)/I-Adjacent Rack - Ikhebuli ye-DAC engenzi lutho noma esebenzayo ilungele ukusebenza okufushane kwe-ToR noma i-rack-to-rack enesabelomali esingabizi kakhulu.
• Phakathi Nomugqa - Ama-DAC asebenzayo angaba yisixazululo esingcono kulolu hlelo lokusebenza, inqobo nje uma ibanga lokudlulisela lingaphansi kuka-15m.
• Ukuphela Komugqa - Izintambo ze-DAC zilungele ukuphela kwezakhiwo zemigqa inqobo nje uma ibanga lingaphakathi komkhawulo wamamitha ayi-15.

Uyini Umehluko Phakathi Kwezintambo Ze-DAC Ezisebenzayo Nezingenasici?
Umehluko omkhulu phakathi kwentambo ye-DAC esebenzayo kanye nekhebula ye-DAC engenzi lutho ukuthi ukucutshungulwa kwesignali kwenziwa noma cha.Uma kunengxenye kagesi yokumisa isignali kukhebuli, iyi-“Active DAC”.Uma kungenjalo, “I-Passive DAC”, njengoba ingasebenzi ugesi ekufakweni kwesignali.Ngaphandle kwengxenye yangaphakathi, izintambo ze-DAC ezisebenzayo nezingenzi lutho nazo ziyahluka enye kwenye ngobude besixhumanisi.Ikhebula ye-DAC Twinax engenzi lutho idlulisa isignali ye-Ethernet ngobude obufushane (0.5 m-5 m), kuyilapho ikhebula esebenzayo ye-DAC Twinax isekela ibanga lokudlulisela elingu-5 m-10 m ngesignali ye-Ethernet.

9 Amakhebuli e-DAC Ajwayelekile Kakhulu:

1. I-10G SFP+ kuya ku-SFP+ DAC
2.25G SFP28 kuya ku-SFP28 DAC
3. 40G QSFP+ kuya ku-QSFP+ DAC
4.40G QSFP+ kuya ku-4×SFP+ DAC
5.100G QSFP28 kuya ku-QSFP28 DAC
6.400G QSFP-DD DAC Cable
7.400G QSFP-DD Ukuze 8 X SFP56 DAC Ikhebula
8.400G QSFP-DD Ukuze 4xQSFP56 DAC Cable
9.400G QSFP-DD Ukuze 2xQSFP56 DAC Cable
