Lenovo 5m QSFP28 Breakout Cable

This Lenovo passive direct-attach cable splits a single QSFP28 port into four SFP28 connections. It provides a 16.40 ft link for high-density networking inside a rack. The assembly is new and ready for deployment in compatible Ethernet environments.

Suited for four-way 28-lane breakout

The cable serves administrators who need to distribute one 28-lane uplink to four separate 28-lane downlinks without active optics or external power. It is not for links that require active signal conditioning or longer reach than the fixed 16.40 ft length allows.

Passive 16.40 ft QSFP28 to 4x SFP28

The defining specification is the passive 16.40 ft construction with a QSFP28 connector on one end and four SFP28 connectors on the other. Verify that both host ports support passive copper at this length before purchasing.

Questions about this item

What rack spacing does the 16.40 ft passive DAC need between the QSFP28 port and the four SFP28 ports?

The cable is 16.40 ft long, so the two patch panels or switches must be positioned within that distance; allow extra slack for the breakout section near the QSFP28 end.

Which orientation do the QSFP28 and SFP28 connectors lock into the ports during installation?

Each connector has a pull-tab latch that clicks when fully seated; insert the QSFP28 end first, then the four SFP28 ends, ensuring every latch engages before routing the cable.

When should the passive DAC be replaced if the latch tabs stop holding the connectors in place?

Replace the cable if any QSFP28 or SFP28 latch fails to stay locked, as a loose connection will cause link errors on the 28 GbE lanes.
