40G QSFP+ to 1x 10G SFP+ Passive DAC, 0.5m (2ft)

The 40G QSFP+ to 1x 10G SFP+ Passive DAC, 0.5m (2ft) is a passive twinax direct attach copper cable with QSFP+ to SFP+, supporting 40Gbps links over a length of 0.5m (2ft). As a passive cable it draws essentially no power and adds no latency to the link. It is a cost effective, low latency interconnect for 40G Ethernet data center and enterprise network environments, and complies with SFF-8636, SFF-8472.

In 40G Ethernet data center and enterprise network environments, the 40G QSFP+ to 1x 10G SFP+ Passive DAC, 0.5m (2ft) provides a factory terminated 40Gbps link between QSFP+ to SFP+ ports. This unit is available in 5 standard lengths from 1m (3ft) to 7m (23ft). The integrated construction removes separate optics from the link budget and reduces the number of failure points in the row. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request.

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 of this assembly varies with length, for example QSFP-40G-1SPC005 for the shortest option. We supply this cable in 1m (3ft), 2m (7ft), 3m (10ft), 5m (16ft) and 7m (23ft). Custom lengths beyond this range can also be produced on request. Wire gauge: 26AWG.

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.

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.

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.

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.
