The 400G QSFP-DD QDD PCxxx Passive DAC provides a 400Gbps copper connection between QSFP-DD to QSFP-DD ports with a cable length of customized length. 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 400G Ethernet data center and cloud network environments.

Product Highlights

• QSFP-DD to QSFP-DD
• Data rate: 400Gbps
• Cable type: Passive Copper Cable

The 400G QSFP-DD QDD PCxxx Passive DAC connects QSFP-DD to QSFP-DD ports at 400Gbps in 400G Ethernet data center and cloud network environments. 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.

Compliance: industry MSA standards. 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 model is supplied at standard length under part number QDD-400G-PCxxx. Other lengths of the same assembly can be produced on request. Wire gauge: 30AWG for 0.5/1/1.5m, 28AWG for 2m, 26AWG for 2.5/3m.

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.

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.

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.

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.
