  • 10 Gbps throughput via passive copper twinax
  • 5 m reach for rack-to-rack links
  • Broad vendor compatibility across major switch brands
  • Hot-pluggable SFP+ footprint enables live swaps
  • Operates 0–70 °C with low crosstalk design

Passive 10 Gb SFP+ DAC Cable

This 1.5-metre passive twinax cable provides a direct 10 Gb Ethernet link between two SFP+ ports. It suits data-centre racks, storage arrays and high-density switch uplinks where a short, low-cost copper reach is preferred over optics. The blue jacket aids quick visual identification in crowded patch panels. No external power is required for the cable assembly itself.

Thermals, noise and power

The passive design draws negligible power and adds no active cooling noise to the rack. Operating temperature range is specified from 0 to 70 °C, matching standard data-centre environmental limits. Low crosstalk construction and compliance with SFF-8432 ensure signal integrity without generating measurable heat. Hot-pluggable SFP+ connectors allow insertion or removal without powering down the host equipment.

1.5-metre reach constraint

The fixed 1.5-metre length determines the maximum separation between connected SFP+ ports. Installations needing longer runs must choose an active optical cable or transceiver pair instead. Backward compatibility to 1 Gbps lets the same cable serve slower links, but the physical reach remains unchanged. Verify rack layout and cable-management slack before ordering.

Questions about this item

How do I install this 1.5m SFP+ DAC cable, and what step do people often miss?

Insert each end into an SFP+ port until the latch clicks; the hot-pluggable 20PIN design means no tools or power-down are required, but users sometimes forget to remove the dust caps first.

What maintenance or replacement will this passive twinax cable need later?

No active components or firmware exist inside; only inspect the connectors for dust or bent pins and replace the cable if the latch breaks or the AWG30 copper shows physical damage.

What limit appears first when this cable runs at 10Gbps continuously in a 70°C cabinet?

The 0–70°C operating range is the first bound; sustained heat near the top of that window can increase insertion loss on the passive copper before any data-rate ceiling is reached.
