400G QSFP-DD QDD PC Passive DAC, 0.5m
The 400G QSFP-DD QDD PC Passive DAC, 0.5m is a passive twinax direct attach copper cable with QSFP-DD to QSFP-DD, supporting 400Gbps links over a length of 0.5m (2ft). As a passive cable it draws essentially no power and adds no latency to the link. It is a cost effective, low latency interconnect for 400G Ethernet data center and cloud network environments, and complies with IEEE 802.3cd, QSFP-DD MSA, CMIS 4.0.

Applications
The 400G QSFP-DD QDD PC Passive DAC, 0.5m connects QSFP-DD to QSFP-DD ports at 400Gbps in 400G Ethernet data center and cloud network environments. This unit is delivered in 6 standard lengths from 0.5m (2ft) to 3m (10ft). The integrated construction removes separate optics from the link budget and reduces the number of failure points in the row. If your project needs a specific vendor coding or custom label, our production line handles it as a routine step before packing.
Standards and Compatibility
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.
Ordering Information
The ordering part number is QDD-400G-PC. We make this cable in 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft), 2.5m (8ft) and 3m (10ft). Special lengths outside this range can be produced to order. Wire gauge: 30AWG. Samples for testing can be arranged before bulk orders.
Packaging
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.
Custom-made Fiber Products
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.
Delivery
Goods are normally sent by courier such as DHL, UPS, FedEx, TNT or EMS; air and sea freight are also available on request. Commonly used items are kept in stock for immediate shipment, and out-of-stock items are usually delivered within a few working days. We can also ship on your courier account or hand goods to your appointed forwarder.
Quality Assurance
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.
