Lenovo 5M Passive SFP28 DAC 16.40 ft

This Lenovo cable is a 16.40 ft passive direct-attach copper assembly with SFP28 connectors on both ends. It provides a physical link between compatible network ports without an external power source. The passive design keeps latency low and installation simple. It is sold as a new component for networking infrastructure.

Suits installers who need a 16.40 ft reach between

The fixed length fits racks or rows where that exact distance matches the patch plan. Buyers who need a different cable length should look at other options. Anyone requiring active signal conditioning or optical transmission will not be served by this passive copper assembly. It does not support connector types other than SFP28.

Passive copper construction decides fit

Because the cable is passive, it draws no power and adds no active electronics to the link budget. That characteristic determines whether the host equipment can drive the 16.40 ft span reliably. Verify that your switches or adapters support passive SFP28 DACs at this length before purchasing.

Questions about this item

What does the 16.40 ft length mean when the cable is installed between two racks?

The 16.40 ft length gives you that exact reach between two SFP28 ports, so you can span adjacent racks or a rack-to-switch run without extra slack.

What does the SFP28 connector cap in practice?

The SFP28 connectors mate directly with SFP28 ports on switches, NICs or transceivers, limiting the link to equipment that accepts the SFP28 form factor.

What does the passive design need to fit or mount?

The passive cable needs two free SFP28 cages and enough clearance for the 16.40 ft cable route; no power adapter or active cooling is required.
