QSFP28 breakout cable splitting into four SFP28 connectors, 1.64FT length

Vszerda

Vszerda QSFP28 to 4x SFP28 Breakout Cable 1.64FT

SKU CH-AKX9-475XM

Connects one 100 Gbps QSFP28 port to four SFP28 ports using a 1.64 ft passive DAC breakout cable compliant with IEEE 802.3 bj/by and InfiniBand EDR

Cable Length 10 Feet

  • 100Gbps aggregate throughput for high-speed LAN and HPC links
  • Breaks one QSFP28 port into four SFP28 connections for flexible topology
  • IEEE 802.3 bj and InfiniBand EDR compliant for broad equipment support
  • 26–30AWG construction with custom braid termination limits EMI radiation
  • Pull-to-release slide latch enables quick, secure insertion and removal

100Gbps QSFP28 Breakout Cable

The Vszerda cable splits one QSFP28 port into four SFP28 connections for 100Gbps aggregate throughput. It suits LAN, HPC and SAN environments that need high-density interconnects. The 1.64ft length keeps rack runs short and tidy. RoHS compliant materials meet environmental standards.

Suits 100G Ethernet and InfiniBand EDR links

Builders who need to fan out a single 100Gbps switch port to four servers or storage nodes will use this cable. It is not for links that require longer reach than 1.64ft or for equipment lacking QSFP28 and SFP28 cages. Buyers wanting optical transmission instead of direct-attach copper should look elsewhere.

100Gbps aggregate data rate

The cable supports 100Gbps total bandwidth across the four lanes, compliant with IEEE 802.3 bj and InfiniBand EDR. This single figure decides whether the link matches your switch and NIC port speeds. Verify that both ends of the connection operate at this rate before ordering.

Questions about this item

How do I install the QSFP28 breakout cable and what step is often missed?

Insert the QSFP28 end into the switch port until the pull-to-release latch clicks, then connect each SFP28 leg to the server NICs; the step often missed is verifying the equipment model for compatibility before ordering.

What maintenance or replacement will this 100Gbps DAC assembly need over time?

The passive copper cable requires no scheduled maintenance; replace it only if the 26AWG to 30AWG conductors show physical damage or if link errors appear on the 100Gbps lanes.

What limit appears first when running sustained 100Gbps traffic through the 1.64ft breakout?

The 0.5 metre copper length keeps insertion loss and crosstalk within IEEE 802.3 bj and InfiniBand EDR specs, so the first limit is typically the port buffer or switch ASIC rather than the cable itself.
