400G OSFP RHS/Flat Top to 400G QSFP-DD Passive DAC Cable (OFL-400G-QDD8xPPCxxx)
For short reach 400Gbps links in 400G Ethernet data center and cloud network environments, the 400G OSFP RHS/Flat Top to 400G QSFP-DD Passive DAC Cable (OFL-400G-QDD8xPPCxxx) offers a factory terminated passive dac assembly with OSFP (RHS/Flat Top) to QSFP-DD connectors and a length of 0.5m (2ft)~3m (10ft). As a passive cable it draws essentially no power and adds no latency to the link. The cable meets IEEE 802.3bs, OSFP MSA, QSFP-DD MSA, CMIS 4.0.

Applications
Designed for 400G Ethernet data center and cloud network environments, the 400G OSFP RHS/Flat Top to 400G QSFP-DD Passive DAC Cable (OFL-400G-QDD8xPPCxxx) carries 400Gbps between OSFP (RHS/Flat Top) to QSFP-DD interfaces. This unit is supplied at 0.5m (2ft)~3m (10ft). The integrated construction removes separate optics from the link budget and reduces the number of failure points in the row. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request. The link runs OSFP-8x 50G-PAM4 QSFP-DD-8x 50G-PAM4 modulation, which keeps it aligned with current 400G switch silicon.
Standards and Compatibility
Standards compliance covers IEEE 802.3bs, OSFP MSA, QSFP-DD MSA, CMIS 4.0. The unit works in any equipment with a standard OSFP (RHS/Flat Top) 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.
Ordering Information
This model is supplied at 0.5m (2ft)~3m (10ft) under part number OFL-400G-QDD8xPPCxxx. Other lengths of the same assembly can be produced on request. Wire gauge: 28~30AWG. Volume pricing is available for project quantities.
Worldwide Delivery
We ship to customers around the world every week. Express couriers handle most orders door to door in a few days; larger consignments go by air or sea to keep freight costs down. Tracking information is provided for every shipment, and we are flexible on shipping accounts and forwarders.
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.
Packaging Options
Default packaging is simple and protective: sealed bag, blister tray, export carton. For OEM customers we also offer white-label packing, custom printed boxes and per-unit labeling with your own part numbers, so the goods can go straight into your sales channel.
Built to Your Spec
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.
