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.

Applications
The 40G QSFP+ to 1x 10G SFP+ Passive DAC, 0.5m (2ft) connects QSFP+ to SFP+ ports at 40Gbps in 40G Ethernet data center and enterprise network environments. This unit is offered in 5 standard lengths from 1m (3ft) to 7m (23ft). Because the assembly is factory terminated and tested as a complete link, installation is plug and play on both ends. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment.
Standards and Compatibility
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.
Ordering Information
The part number changes with length: QSFP-40G-1SPC005 is the shortest standard option. Available lengths are 1m (3ft), 2m (7ft), 3m (10ft), 5m (16ft) and 7m (23ft). If you need a length outside this list, our factory can build it to order. Wire gauge: 26AWG. Volume pricing is available for project quantities.
Delivery
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.
Our Testing Process
Production samples and every outgoing batch pass through bit-error-rate measurement, temperature verification and plug-in compatibility checks on mainstream switches and routers. Because we are the manufacturer, any issue found in testing is fed back to the production line immediately instead of being passed on to customers.
Packaging Options
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.
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.
