TP-Link Omada 1 Meter 25G SFP28 Direct Attach Cable

TP-Link Omada 1 Meter 25G SFP28 Direct Attach Cable (SM6220-1M) - 5 Years Local Warranty

The SM6220-1M is the entry point to 25 Gigabit copper in the Omada range. It sits between the 10G SFP+ DACs and the 100G QSFP28 assemblies, giving a one-metre, no-optics way to link SFP28 ports in the same rack or the one beside it, at a fraction of the cost of two SFP28 transceivers and a fibre patch lead.

25 Gigabit in a rack for the price of copper

This is a passive twin-ax cable assembly with an SFP28 plug fixed to each end, so one part replaces a pair of transceivers plus a fibre lead. At one metre it is built for short hauls: connecting two switches in the same cabinet, cross-linking a redundant pair, or attaching a 25G server or storage node directly. Because both ends are standard SFP28, it serves any Omada switch with SFP28 slots rather than being tied to one model, which keeps spares simple across a mixed estate.

One cable that also covers 10G and 1G ports

The assembly is rated for 25 Gbps and also runs at 10 Gbps and 1 Gbps, so the same part keeps working when a port is configured down or when a link is later re-provisioned. That multi-rate behaviour matters in practice: many Omada aggregation switches present SFP28 slots that negotiate 1/10/25G, and stocking a single DAC rather than three different leads reduces what has to sit in the spares drawer. It also means a 25G-ready cable can be installed today against a 10G switch you intend to replace.

Thin enough to dress properly behind the switch

The conductor is silver-plated copper at 30 AWG and the cable holds a minimum bend radius of 22.5 mm, tight enough to turn immediately behind a patch panel without stressing the assembly. Each SFP28 plug measures 57.5 x 13.55 x 8.55 mm, with an overall length of 1,000 mm. It operates from 0 to 70 degrees C and stores from -40 to 85 degrees C, at 10 to 90 percent non-condensing humidity in service, which covers both a conditioned data hall and a warmer comms room.

Passive by design: no power, no optics to keep clean

Being passive, the cable contains no retimer or laser and consumes no power from the host port; the signal passes as an electrical pair straight between switch SerDes. That removes heat from the cabinet and removes the two failure modes that most often take a 25G optical link down, contaminated fibre end-faces and poorly seated transceivers. Confirm both switch ports support passive direct attach at the rate you need, since a passive assembly relies entirely on the host port's own signal conditioning.

Ideal For

Singapore businesses, schools, hotels and managed-service providers building on Omada, and IT teams that want a accessory they can adopt, monitor and update centrally rather than box by box. Supplied by SourceIT with local Singapore warranty, GST invoice and project pricing on request.
