400G QSFP-DD QDD PC Passive DAC

For short reach 400Gbps links in 400G Ethernet data center and cloud network environments, the 400G QSFP-DD QDD PC Passive DAC, 0.5m offers a factory terminated passive twinax assembly with QSFP-DD to QSFP-DD connectors and a length of 0.5m (2ft). As a passive cable it draws essentially no power and adds no latency to the link. The cable meets IEEE 802.3cd, QSFP-DD MSA, CMIS 4.0.

Designed for 400G Ethernet data center and cloud network environments, the 400G QSFP-DD QDD PC Passive DAC, 0.5m carries 400Gbps between QSFP-DD to QSFP-DD interfaces. This unit is provided in 6 standard lengths from 0.5m (2ft) to 3m (10ft). Because the assembly is factory terminated and tested as a complete link, installation is plug and play on both ends. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment.

This product is designed and tested to comply with IEEE 802.3cd, QSFP-DD MSA, CMIS 4.0. It plugs into any standards-based QSFP-DD to QSFP-DD port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.

This assembly is listed under part number QDD-400G-PC. The cable is supplied in 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft), 2.5m (8ft) and 3m (10ft). Custom lengths beyond the standard range are available on request. Wire gauge: 30AWG. Volume pricing is available for project quantities.

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.

Production samples and every outgoing batch pass through bit-error-rate measurement, temperature verification and plug-in compatibility checks on mainstream switches and routers. Because we are the manufacturer, any issue found in testing is fed back to the production line immediately instead of being passed on to customers.

Transceivers and cables are individually protected against static and dust, then consolidated into sturdy cartons suitable for international courier shipment. For larger orders we shrink-wrap and strap cartons onto pallets. Tell us your warehouse or retail requirements and we will pack accordingly.

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.
