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
The 400G OSFP RHS/Flat Top to 400G QSFP-DD Passive DAC Cable (OFL-400G-QDD8xPPCxxx) connects OSFP (RHS/Flat Top) to QSFP-DD ports at 400Gbps in 400G Ethernet data center and cloud network environments. This unit is supplied at 0.5m (2ft)~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. 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.
Tested Before Shipment
We do not ship untested stock. Each transceiver and cable is powered up in our test racks, checked for link stability, transmit power, receiver sensitivity and diagnostic readouts, and only then packed for delivery. This factory-level testing is one reason network integrators keep reordering from us year after year.
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.
Customization Service
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.
Logistics
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.
