40G QSFP+ to 1x 10G SFP+ Passive DAC, 1m (3ft)

The 40G QSFP+ to 1x 10G SFP+ Passive DAC, 1m (3ft) provides a 40Gbps copper connection between QSFP+ to SFP+ ports with a cable length of 1m (3ft). 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.

Designed for 40G Ethernet data center and enterprise network environments, the 40G QSFP+ to 1x 10G SFP+ Passive DAC, 1m (3ft) carries 40Gbps between QSFP+ to SFP+ interfaces. This unit is available 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. 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 standard part number of this assembly is QSFP-40G-1SPC01-GENERIC. 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. Volume pricing is available for project quantities.

Every unit we ship is tested in our own test bed on mainstream switch and transport platforms before packing. Our test center has been fully upgraded, which sets us apart from other third party product providers: 10G, 40G, 100G, 200G and 400G transceivers and direct attach cables are verified on the latest top brand equipment, including selected original switches that can hardly be found elsewhere.

Standard packing is an anti-static bag plus blister protection, with cartons sized to keep products from moving in transit. We apply our standard labels by default; neutral packing or customer-branded labels, part number stickers and serial barcodes are all available on request.

Because we are the factory, customization is straightforward: non-standard lengths, different jacket materials, specific polarity or breakout wiring, and compatibility programming for particular switch brands are all routine work for us. Small trial orders are accepted so you can verify quality before scaling up.

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.
