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 stocked in 6 standard lengths from 0.5m (2ft) to 3m (10ft). 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.

Standards compliance covers IEEE 802.3cd, QSFP-DD MSA, CMIS 4.0. The unit works in any equipment with a standard QSFP-DD to QSFP-DD interface; if your network uses a specific vendor's coding, tell us the switch model and we will program and verify it before delivery.

Order reference: part number QDD-400G-PC. Standard supply covers 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft), 2.5m (8ft) and 3m (10ft). Custom length production is available for project requirements. 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.

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.

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.

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.
