Axiom 40G QSFP+ to SFP+ passive DAC cable 10ft

Axiom

Axiom 462-3640-AX 40G QSFP+ to SFP+ 10ft Passive DAC

SKU CH-Q9JG-J4SXG

A 10-foot passive DAC splits a 40 G QSFP+ port into four 10 G SFP+ links

  • 40 Gbps aggregate bandwidth from a single QSFP+ port
  • Splits into four 10 Gbps SFP+ links for flexible topology
  • Passive twinax construction needs no external power
  • 10 ft reach connects adjacent racks without signal loss

Direct-attach breakout cable

The Axiom 462-3640-AX provides a 40G QSFP+ to four 10G SFP+ passive breakout for Dell-compatible equipment. It suits data-centre operators and network engineers who need a single-cable uplift from a 40 GbE port to four 10 GbE links without active optics. The ten-foot twinaxial assembly arrives new and ready for rack installation.

Thermals and power

Passive copper construction draws no external power and generates negligible heat during normal operation. No onboard active components mean silent running and no firmware or driver load on the host switch. The cable simply conducts differential pairs between the QSFP+ and SFP+ ends within standard signal-integrity limits for the rated length.

Pitanja o ovom artiklu

How do I install the Axiom 462-3640-AX 40G QSFP+ to SFP+ passive DAC without damaging the connectors?

Align the QSFP+ end with the 40G port and the four SFP+ ends with 10G ports, then push each module straight in until the latch clicks; forcing at an angle bends the twinaxial pins.

What maintenance or replacement will the Axiom 462-3640-AX 40G QSFP+ to SFP+ passive DAC need over time?

The passive twinaxial cable has no active components, so only inspect the latch tabs and connector ends for dust or bent pins; replace the assembly if link errors appear.
