Direct-attach copper for 10 GbE links

The STARTECH SFPCMM3M is a passive SFP+ Twinax cable built for 10 GbE connections between switches, servers or storage. It replaces fibre modules with a lower-cost copper link that draws under 0.05 W and installs without powering down the chassis.

Upgrade from fibre transceivers or shorter DACs

Use this cable when you need a 3 m reach (9.8 ft) and want to avoid the expense and power draw of optical SFP+ transceivers. The jump is worth it for rack-to-rack or top-of-rack runs where latency must stay low and the link budget fits passive copper.

Handles 10 GbE and 1x-8x Fibre Channel over 3 m

The 30 AWG conductors meet the 100 Ohm impedance target for 10 GbE and 1x, 2x, 4x and 8x Fibre Channel. Beyond 3 m the passive design runs out of margin, so longer spans require active or optical alternatives.

Questions about this item

What SFP+ port spacing and latching mechanism does the 3 m passive twinax cable require?

The cable uses standard SFP+ latching plugs on both ends that fit any MSA-compliant SFP+ cage with 100 Ohm differential impedance.

How do I correctly seat the SFP+ connectors, and what is the common mistake?

Insert each end straight until the latch clicks; the frequent error is angling the module, which bends the 30 AWG twinax pairs and breaks the latch.

When should the 3 m DAC be replaced, and what wear signs appear first?

Replace it if link errors rise or the latch no longer holds; the PVC jacket and passive copper have no active components to degrade beyond physical damage.
