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: 2 standard lengths between 7m (23ft) to 10m (33ft)
• Operating temperature: 0 to 70°C (32 to 158°F)

In 40G Ethernet data center and enterprise network environments, the 40G QSFP+ Active DAC, 7m (23ft) provides a factory terminated 40Gbps link between QSFP+ to QSFP+ ports. This unit is provided 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.

This product is designed and tested to comply with 40G InfiniBand 8x DDR, 4x QDR, 10G/40Gigabit Ethernet, Fibre Channel. It is interoperable with Cisco equipment and serves as a direct equivalent to the Cisco part number QSFP-H40G-ACU7M.

This assembly is listed under part number QSFP-40G-AC07. The cable is supplied in 7m (23ft) and 10m (33ft). Custom lengths beyond the standard range are available on request. Wire gauge: 26AWG.

Because we are the factory, customization is straightforward: non-standard lengths, different jacket materials, specific polarity or breakout wiring, and compatibility programming for particular switch brands are all routine work for us. Small trial orders are accepted so you can verify quality before scaling up.

We ship to customers around the world every week. Express couriers handle most orders door to door in a few days; larger consignments go by air or sea to keep freight costs down. Tracking information is provided for every shipment, and we are flexible on shipping accounts and forwarders.

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.

Standard packing is an anti-static bag plus blister protection, with cartons sized to keep products from moving in transit. We apply our standard labels by default; neutral packing or customer-branded labels, part number stickers and serial barcodes are all available on request.
