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

For short reach 40Gbps links in 40G Ethernet data center and enterprise network environments, the 40G QSFP+ to 1x 10G SFP+ Passive DAC, 1m (3ft) offers a factory terminated passive twinax assembly with QSFP+ to SFP+ connectors and a length of 1m (3ft). As a passive cable it draws essentially no power and adds no latency to the link. The cable meets SFF-8636, SFF-8472.

In 40G Ethernet data center and enterprise network environments, the 40G QSFP+ to 1x 10G SFP+ Passive DAC, 1m (3ft) 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). It installs directly into standard ports with no separate transceivers or patch cords to manage at either end. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment.

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.

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. Samples for testing can be arranged before bulk orders.

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.

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.

We have manufactured fiber optic connectivity products since 1995 and run our own production lines in Shenzhen. Beyond the standard catalog we build to order: special cable lengths, custom connector combinations, vendor-specific compatibility coding and private labeling. Send us your requirement and our engineers will quote a practical solution.

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.
