40G QSFP+ Passive DAC

The 40G QSFP+ Passive DAC, 1m (3ft) provides a 40Gbps copper connection between QSFP+ to QSFP+ ports with a cable length of 1m (3.28ft). As a passive cable it draws essentially no power and adds no latency to the link. Direct attach copper keeps both latency and power consumption to a minimum, which makes it the economical choice for 40G Ethernet data center and enterprise network environments.

Product Highlights

• QSFP+ to QSFP+
• Data rate: 40Gbps
• Length: 7 standard lengths between 0.5m (2ft) to 7m (23ft)
• Operating temperature: 0 to 70°C (32 to 158°F)

Designed for 40G Ethernet data center and enterprise network environments, the 40G QSFP+ Passive DAC, 1m (3ft) carries 40Gbps between QSFP+ to QSFP+ interfaces. This unit is provided in 7 standard lengths from 0.5m (2ft) to 7m (23ft). Because the assembly is factory terminated and tested as a complete link, installation is plug and play on both ends. For networks standardized on Cisco hardware, it is a drop-in equivalent of the QSFP-H40G-CU1M.

On the compatibility side, this unit is the practical equivalent of the Cisco part QSFP-H40G-CU1M and works in Cisco systems out of the box. Standards compliance covers SFF-8436, QSFP+ MSA and IEEE 802.3ba.

This assembly is listed under part number QSFP-40G-PC01. The cable is supplied in 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft), 3m (10ft), 5m (16ft) and 7m (23ft). Custom lengths beyond the standard range are available on request. Wire gauge: 30AWG. Samples for testing can be arranged before bulk orders.

Goods are normally sent by courier such as DHL, UPS, FedEx, TNT or EMS; air and sea freight are also available on request. Commonly used items are kept in stock for immediate shipment, and out-of-stock items are usually delivered within a few working days. We can also ship on your courier account or hand goods to your appointed forwarder.

Before any product leaves our factory it goes through optical performance testing, compatibility verification on real switch platforms and a final visual inspection. Our in-house test lab holds a wide range of current and legacy switches from major brands, so interoperability is proven on the actual equipment your network uses rather than assumed from paper specifications.

Products are first packed into blister trays or self-sealed bags and then into cartons. Standard labels and marks are applied by default, and customized packing and labeling are available on request.

Our product line has grown with the industry for three decades, from GBIC-era modules to today's 800G and 1.6T interconnects. If the exact configuration you need is not listed, we can usually build it: custom lengths, mixed connector breakouts, OEM branding and project-specific firmware coding are all supported.
