40G QSFP+ to 1x 10G SFP+ Passive DAC

The 40G QSFP+ to 1x 10G SFP+ Passive DAC, 1m (3ft) is a passive twinax direct attach copper cable with QSFP+ to SFP+, supporting 40Gbps links over a length of 1m (3ft). 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.

Product Highlights

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 provided 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.

Compliance: SFF-8636, SFF-8472. Every unit's EEPROM coding and link behavior are verified on real host equipment in our lab, so what arrives at your site is ready to use.

This assembly is listed under part number QSFP-40G-1SPC01-GENERIC. 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.

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.

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.

We do not ship untested stock. Each transceiver and cable is powered up in our test racks, checked for link stability, transmit power, receiver sensitivity and diagnostic readouts, and only then packed for delivery. This factory-level testing is one reason network integrators keep reordering from us year after year.
