Short black SFP+ direct attach copper cable with connectors on both ends

Mellanox Technologies

Mellanox MC3309130-00A 10GbE SFP+ DAC network ethernet cable 0.5m

SKU CH-QQ3Q-KPXQS

A 0.5 m passive copper cable carries 10 GbE over SFP+ ports without external power

  • 5 m passive copper link needs no extra power
  • 10 GbE SFP+ direct attach for short-reach server links
  • SFF-8418 and SFF-8419 compliant for multi-vendor interoperability
  • Ultra-low crosstalk and low insertion loss keep signal integrity tight
  • BER better than 1E-15 ensures reliable data centre throughput

Direct-attach copper cable for 10 GbE SFP+ ports

This passive Mellanox cable links two SFP+ interfaces at 10 Gb/s over a half-metre reach. It draws no external power and meets SFF-8418 and SFF-8419 mechanical and electrical specifications. The 0.5 m length suits adjacent switches, servers or storage nodes inside a single rack.

Replaces active optical or active copper assemblies

By removing transceivers and separate patch cords the cable cuts component count and eliminates the power draw of active links. The jump is worthwhile when port density and latency matter more than reach beyond seven metres. Buyers who need longer runs or fibre isolation cannot use this passive copper design.

Maintains signal integrity under continuous load

Ultra-low crosstalk and low insertion loss keep the bit-error rate better than 1E-15 during sustained 10 Gb/s traffic. Passive construction means no active equaliser to degrade or overheat, so performance stays consistent in dense, high-temperature rack environments.

Questions about this item

What SFP+ port spacing does the 0.5 m MC3309130-00A cable need?

The cable plugs directly into any standard SFP+ port; its 0.5 m length suits adjacent or same-rack switches and servers.

Which end goes in first when installing the MC3309130-00A DAC?

Either end can be inserted first; the common mistake is not pushing each connector until the latch clicks, which leaves the link down.

When should the MC3309130-00A cable be replaced?

Replace it if the latch breaks, the copper twinax is kinked, or the link shows errors despite clean ports and correct seating.
