Intellinet Network Solutions 508490 QSFP+ 40G Passive DAC Twinax Cable 1.5 ft

SKU CH-8AT0-3SSGJ MPN 508490

A 1.5 ft passive QSFP+ direct-attach copper twinax cable delivering 40 Gbps with under 0.15 W draw for short-range switch-to-server links up to 23 ft

  • Length1.50 ft.
  • ColorBlack
  • Passive copper design consumes under 0.15 W for energy-efficient rack links
  • MSA-compliant QSFP+ connectors work with Cisco, Ubiquiti, TP-Link and other major switches
  • 40 Gbps throughput over 1.5 ft twinax for low-latency server-to-switch connections
  • Direct-attach copper eliminates separate transceivers to simplify short-range deployment up to 23 ft
  • AWG 30 construction operates reliably up to 70 °C (158 °F) in dense data-centre environments

reach 40 Gbps interconnect

This 1.5 ft passive QSFP+ DAC twinax cable links switches, routers, servers or storage at up to 40 Gbps. It targets network engineers building top-of-rack or adjacent-rack runs where fibre would be over-specified and RJ45 latency is unacceptable. The MSA-compliant design works with major vendors including Cisco, Ubiquiti and TP-Link.

Passive copper simplicity

Because the cable carries the electrical signal directly, no transceiver modules are required on either end. That removes the need to match optics, cuts component count and reduces insertion loss. Power draw stays below 0.15 W and the assembly generates no measurable heat, so it operates reliably up to 70 °C (158 °F) without extra cooling.

Up to seven metres of headroom

The 1.5 ft length suits intra-rack or side-by-side rack connections with minimal slack. Passive DAC is rated for distances up to 7 m (23 ft), so this cable leaves ample margin for re-cabling within the same row. Beyond that range a different media type would be needed.

Questions about this item

Will the QSFP+ connectors on this 1.5 ft cable need replacement or re-seating over time?

The passive copper twinax construction has no active components to wear out; connectors are rated for standard mating cycles and require no scheduled maintenance.

What is the first limit reached when this cable runs at 40 Gbps continuously?

The 70 °C (158 °F) operating temperature ceiling is the primary sustained-use boundary; the cable draws under 0.15 W and produces no measurable heat itself.

How much noise, heat or power does this 1.5 ft DAC add when installed all day?

Zero audible noise, no heat generated by the cable, and less than 0.15 W total power draw from the passive twinax assembly.
