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). The integrated construction removes separate optics from the link budget and reduces the number of failure points in the row. 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.

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.

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.

Goods are normally sent by courier such as DHL, UPS, FedEx, TNT or EMS; air and sea freight are also available on request. Commonly used items are kept in stock for immediate shipment, and out-of-stock items are usually delivered within a few working days. We can also ship on your courier account or hand goods to your appointed forwarder.

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.

Each unit is sealed in an anti-static bag, cushioned in a blister tray and boxed in an export-grade carton. Outer cartons carry handling marks and can be palletized for air or sea freight. If your project requires retail boxes, barcodes or your own brand on the label, we can arrange that as well.

As a manufacturer serving the fiber optic industry since 1995, we have strong in-house manufacturing and design capability. From early GBIC, Xenpak and X2 modules to today's SFP, SFP+, QSFP, QSFP-DD and OSFP products, we grow together with the industry. OEM and custom-designed transceivers and cables are welcome, and our factory-direct pricing is very competitive compared with online retail stores.
