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.

In 400G Ethernet data center and cloud network environments, the 400G QSFP-DD QDD PC Passive DAC, 0.5m provides a factory terminated 400Gbps link between QSFP-DD to QSFP-DD ports. This unit is manufactured 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. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request.

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.

Part number of this model: QDD-400G-PC. Length options are 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft), 2.5m (8ft) and 3m (10ft). Our factory also produces custom lengths beyond these on request. Wire gauge: 30AWG.

Our product line has grown with the industry for three decades, from GBIC-era modules to today's 800G and 1.6T interconnects. If the exact configuration you need is not listed, we can usually build it: custom lengths, mixed connector breakouts, OEM branding and project-specific firmware coding are all supported.

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.

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.
