The 40G QSFP+ to 1x 10G SFP+ Passive DAC, 0.5m (2ft) provides a 40Gbps copper connection between QSFP+ to SFP+ ports with a cable length of 0.5m (2ft). 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.

The 40G QSFP+ to 1x 10G SFP+ Passive DAC, 0.5m (2ft) is a 40Gbps direct attach copper cable for QSFP+ to SFP+ connections in 40G Ethernet data center and enterprise network environments. This unit is provided in 5 standard lengths from 1m (3ft) to 7m (23ft). It installs directly into standard ports with no separate transceivers or patch cords to manage at either end. If your project needs a specific vendor coding or custom label, our production line handles it as a routine step before packing.
This product is designed and tested to comply with SFF-8636, SFF-8472. It plugs into any standards-based QSFP+ to SFP+ port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.
The part number varies by length, e.g. QSFP-40G-1SPC005 at the shortest standard option. The cable is supplied in 1m (3ft), 2m (7ft), 3m (10ft), 5m (16ft) and 7m (23ft). Custom lengths beyond the standard range are available on request. Wire gauge: 26AWG. Samples for testing can be arranged before bulk orders.
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.
As a manufacturer serving the fiber optic industry since 1995, we have strong in-house manufacturing and design capability. From early GBIC, Xenpak and X2 modules to today's SFP, SFP+, QSFP, QSFP-DD and OSFP products, we grow together with the industry. OEM and custom-designed transceivers and cables are welcome, and our factory-direct pricing is very competitive compared with online retail stores.
Our warehouse keeps fast-moving transceivers and cables ready for same-week dispatch. Courier, air freight and sea freight options are all available depending on your budget and schedule, and we consolidate multiple items into one shipment whenever it saves you cost.
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.
