400G OSFP 8x 50G PAM4 Flat Top to QSFP-DD 8x 50G PAM4 Passive DAC Cable, 3m

The 400G OSFP 8x 50G PAM4 Flat Top to QSFP-DD 8x 50G PAM4 Passive DAC Cable, 3m provides a 400Gbps copper connection between OSFP (RHS/Flat Top) to QSFP-DD ports with a cable length of 3m (10ft). As a passive cable it draws essentially no power and adds no latency to the link. Direct attach copper keeps both latency and power consumption to a minimum, which makes it the economical choice for 400G Ethernet data center and cloud network environments.

Applications
The 400G OSFP 8x 50G PAM4 Flat Top to QSFP-DD 8x 50G PAM4 Passive DAC Cable, 3m is a 400Gbps direct attach copper cable for OSFP (RHS/Flat Top) to QSFP-DD connections in 400G Ethernet data center and cloud network environments. This unit is delivered 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. 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 802.3bs, 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
The ordering part number is OFL-400G-QDD8XPPC. We make this cable in 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft) and 3m (10ft). Special lengths outside this range can be produced to order. Wire gauge: 28AWG. Volume pricing is available for project quantities.
Shipping and Lead Time
Standard products are held in stock and usually ship within one to three working days. We dispatch worldwide by DHL, UPS, FedEx, TNT or EMS, and for bulk orders we arrange air or sea freight. Shipments can also be sent collect on your own courier account or delivered to your freight forwarder.
Our Testing Process
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.
Packing Details
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.
Factory Custom Capability
Working directly with the manufacturer means no middleman limits. We support OEM and ODM projects, custom cable assemblies, alternative packaging and compatibility coding for major equipment vendors, with engineering support from the same team that designs our standard products.
