The 400G OSFP 8x 50G PAM4 Flat Top to QSFP-DD 8x 50G PAM4 Passive DAC Cable, 3m is a passive dac direct attach copper cable with OSFP (RHS/Flat Top) to QSFP-DD, supporting 400Gbps links over a length of 3m (10ft). 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 802.3bs, OSFP MSA, QSFP-DD MSA, CMIS 4.0.

Applications
In 400G Ethernet data center and cloud network environments, the 400G OSFP 8x 50G PAM4 Flat Top to QSFP-DD 8x 50G PAM4 Passive DAC Cable, 3m provides a factory terminated 400Gbps link between OSFP (RHS/Flat Top) to QSFP-DD ports. This unit is offered in 5 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 and Compatibility
This product is designed and tested to comply with IEEE 802.3bs, OSFP MSA, QSFP-DD MSA, CMIS 4.0. It plugs into any standards-based OSFP (RHS/Flat Top) to QSFP-DD port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.
Ordering Information
Order this assembly under part number OFL-400G-QDD8XPPC. Available lengths are 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft) and 3m (10ft). If you need a length outside this list, our factory can build it to order. Wire gauge: 28AWG. Volume pricing is available for project quantities.
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.
How We Pack
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.
OEM and Custom Orders
We have manufactured fiber optic connectivity products since 1995 and run our own production lines in Shenzhen. Beyond the standard catalog we build to order: special cable lengths, custom connector combinations, vendor-specific compatibility coding and private labeling. Send us your requirement and our engineers will quote a practical solution.
How We Ship
Most orders travel by international express and arrive within days; palletized freight by air or sea is used for volume orders. If you prefer, we ship on your DHL, UPS or FedEx account, or deliver to your appointed agent in China for onward consolidation.
