40G QSFP+ Active DAC

The 40G QSFP+ Active DAC, 7m (23ft) is a twinax direct attach copper cable with QSFP+ to QSFP+, supporting 40Gbps links over a length of 7m (22.97ft). Active electronics inside the connectors extend the usable reach compared with passive copper while keeping power draw low. It is a cost effective, low latency interconnect for 40G Ethernet data center and enterprise network environments, and complies with 40G InfiniBand 8x DDR, 4x QDR, 10G/40Gigabit Ethernet, Fibre Channel.

Product Highlights

• QSFP+ to QSFP+
• Data rate: 40Gbps
• Length: available from 7m (23ft) to 10m (33ft) in 2 standard options
• Operating temperature: 0 to 70°C (32 to 158°F)

The 40G QSFP+ Active DAC, 7m (23ft) connects QSFP+ to QSFP+ ports at 40Gbps in 40G Ethernet data center and enterprise network environments. This unit is supplied in 2 standard lengths from 7m (23ft) to 10m (33ft). The integrated construction removes separate optics from the link budget and reduces the number of failure points in the row. Compatibility with Cisco systems is verified in our own test lab before shipment, so the unit works out of the box as an equivalent of QSFP-H40G-ACU7M.

On the compatibility side, this unit is the practical equivalent of the Cisco part QSFP-H40G-ACU7M and works in Cisco systems out of the box. Standards compliance covers 40G InfiniBand 8x DDR, 4x QDR, 10G/40Gigabit Ethernet, Fibre Channel.

This model carries part number QSFP-40G-AC07. You can order this assembly in 7m (23ft) and 10m (33ft). Non-standard lengths can be produced on request. Wire gauge: 26AWG.

Working directly with the manufacturer means no middleman limits. We support OEM and ODM projects, custom cable assemblies, alternative packaging and compatibility coding for major equipment vendors, with engineering support from the same team that designs our standard products.

Most orders travel by international express and arrive within days; palletized freight by air or sea is used for volume orders. If you prefer, we ship on your DHL, UPS or FedEx account, or deliver to your appointed agent in China for onward consolidation.

We do not ship untested stock. Each transceiver and cable is powered up in our test racks, checked for link stability, transmit power, receiver sensitivity and diagnostic readouts, and only then packed for delivery. This factory-level testing is one reason network integrators keep reordering from us year after year.

Default packaging is simple and protective: sealed bag, blister tray, export carton. For OEM customers we also offer white-label packing, custom printed boxes and per-unit labeling with your own part numbers, so the goods can go straight into your sales channel.
