400G OSFP RHS/Flat Top to 400G QSFP-DD Passive DAC Cable (OFL-400G-QDD8xPPCxxx)

The 400G OSFP RHS/Flat Top to 400G QSFP-DD Passive DAC Cable (OFL-400G-QDD8xPPCxxx) provides a 400Gbps copper connection between OSFP (RHS/Flat Top) to QSFP-DD ports with a cable length of 0.5m (2ft)~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.

The 400G OSFP RHS/Flat Top to 400G QSFP-DD Passive DAC Cable (OFL-400G-QDD8xPPCxxx) 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 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. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request.

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.

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. Samples for testing can be arranged before bulk orders.

Products are first packed into blister trays or self-sealed bags and then into cartons. Standard labels and marks are applied by default, and customized packing and labeling are available on request.

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.

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.

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.
