5 metre active twinax cable with QSFP+ connectors at each end

STARTECH

STARTECH 5m 40Gbps QSFP+ to QSFP+ Active Twinax Cable

SKU CH-T6WW-67B7D

A 5-metre active twinax cable with QSFP+ connectors delivering 40 Gbps for Cisco and MSA-compliant switches

  • 40 Gbps throughput for high-speed data transfer over 16.4 ft
  • Active Twinax copper design extends reach beyond passive cable limits
  • Hot-swappable QSFP+ connectors allow installation without network downtime
  • Tested for Cisco Firepower ASR1000 ASR9000 C9300 C3650 compatibility
  • MSA compliant for use with Ubiquiti D-Link Netgear Supermicro TP-Link switches

5m 40Gbps QSFP+ Active Twinax Cable

This five-metre active copper cable delivers 40Gbps connectivity between two QSFP+ ports. It suits data-centre operators and network engineers who need a direct-attach link for Cisco Firepower, ASR1000, ASR9000, C9300 or C3650 switches. The low-power active design extends reach without external power.

Hot-swappable MSA build with 30 AWG conductors

The cable uses 30 AWG twinax conductors inside a PVC jacket and presents 100 Ohm differential impedance. Hot-swappable QSFP+ ends allow insertion or removal without downtime, while MSA compliance ensures mechanical fit in multi-vendor switches from Ubiquiti, D-Link, Netgear, Supermicro and TP-Link.

Replaces shorter passive DACs when rack spacing

Active circuitry maintains signal integrity at 5m where passive copper would fail, making the jump worthwhile for cross-rack or row-to-row links. It is not for teams who need longer than 5m, fibre-based 40GbE, or breakout to multiple 10GbE ports.

Questions about this item

What speed does the 40Gbps QSFP+ interface actually deliver?

The cable operates at 40 Gbps using active twinax copper with 100 Ohm impedance and 30 AWG conductors.

What physical space and connector type does this 5m DAC require?

It needs two QSFP+ ports and 5 metres (16.4 ft) of cable routing space with a PVC jacket.

How is the active twinax cable installed and what step is often missed?

Insert both QSFP+ ends into compatible ports; the active circuitry powers on automatically, but users sometimes forget to verify MSA compliance on non-Cisco switches.
