Axiom passive DAC cable QSFP28 to four SFP28 connectors 1M

Axiom

Axiom 100GBASE-CR4 QSFP28 to 4 SFP28 passive DAC 1M

SKU CH-VXJM-5V8XD

Connects a 100G QSFP28 port to four 25G SFP28 ports over a 3.3 ft passive copper cable

  • 100 Gbps total bandwidth from four 25 Gbps lanes
  • 3 ft passive copper avoids external power needs
  • QSFP28 breakout connects four SFP28 ports directly
  • Juniper-compatible coding ensures immediate link-up

100GBASE-CR4 breakout cable for Juniper networks

This passive direct-attach cable splits a single QSFP28 port into four independent SFP28 connections. It is built for data-centre operators who need 100 Gbps aggregate bandwidth across four 25 Gbps links without the cost or power draw of active optics. The one-metre reach suits adjacent rack connections in high-density deployments.

Passive copper construction limits reach to short

Because the assembly uses passive copper twinax, signal integrity is guaranteed only over the specified 3.3 ft length; longer distances would require active optical cables or transceivers. Buyers who need extended reach between racks or across rows cannot use this cable. The fixed breakout design also prevents reconfiguration into a single 100 Gbps link or alternative fan-out ratios.

Highlights

  • 100 Gbps total bandwidth from four 25 Gbps lanes
  • 3 ft passive copper avoids external power needs
  • QSFP28 breakout connects four SFP28 ports directly
  • Juniper-compatible coding ensures immediate link-up

Questions about this item

What does the 100 Gb/s rating mean when the cable is installed?

The cable carries four 25 Gb/s lanes that combine to a 100 Gb/s aggregate link between the QSFP28 and SFP28 ports.

What does the CR4 designation limit in practice?

CR4 specifies four copper lanes at 25 Gb/s each, capping the assembly at 100 Gb/s total throughput.
