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.

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 supplied 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. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request.

Standards compliance covers SFF-8636, SFF-8472. The unit works in any equipment with a standard QSFP+ to SFP+ interface; if your network uses a specific vendor's coding, tell us the switch model and we will program and verify it before delivery.

This model carries part number QSFP-40G-1SPC01-GENERIC. You can order this assembly in 1m (3ft), 2m (7ft), 3m (10ft), 5m (16ft) and 7m (23ft). Non-standard lengths can be produced on request. Wire gauge: 26AWG.

Each unit is sealed in an anti-static bag, cushioned in a blister tray and boxed in an export-grade carton. Outer cartons carry handling marks and can be palletized for air or sea freight. If your project requires retail boxes, barcodes or your own brand on the label, we can arrange that as well.

Working directly with the manufacturer means no middleman limits. We support OEM and ODM projects, custom cable assemblies, alternative packaging and compatibility coding for major equipment vendors, with engineering support from the same team that designs our standard products.

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.

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.
