40G QSFP+ Passive DAC, 1m (3ft)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.

Applications
In 40G Ethernet data center and enterprise network environments, the 40G QSFP+ Passive DAC, 1m (3ft) provides a factory terminated 40Gbps link between QSFP+ to QSFP+ ports. This unit is stocked in 7 standard lengths from 0.5m (2ft) to 7m (23ft). 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-CU1M.
Standards and Compatibility
This product is designed and tested to comply with SFF-8436, QSFP+ MSA and IEEE 802.3ba. It is interoperable with Cisco equipment and serves as a direct equivalent to the Cisco part number QSFP-H40G-CU1M.
Ordering Information
Order reference: part number QSFP-40G-PC01. Standard supply covers 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft), 3m (10ft), 5m (16ft) and 7m (23ft). Custom length production is available for project requirements. Wire gauge: 30AWG.
How We Ship
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.
Quality Assurance
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.
Package
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.
Built to Your Spec
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.
