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) is a passive dac direct attach copper cable with OSFP (RHS/Flat Top) to QSFP-DD, supporting 400Gbps links over a length of 0.5m (2ft)~3m (10ft). As a passive cable it draws essentially no power and adds no latency to the link. It is a cost effective, low latency interconnect for 400G Ethernet data center and cloud network environments, and complies with IEEE 802.3bs, OSFP MSA, QSFP-DD MSA, CMIS 4.0.

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.

Compliance: IEEE 802.3bs, OSFP MSA, QSFP-DD MSA, CMIS 4.0. Every unit's EEPROM coding and link behavior are verified on real host equipment in our lab, so what arrives at your site is ready to use.

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.

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.

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.

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.

From incoming component inspection to final burn-in, quality is controlled at each step of production. Finished units are verified on real networking equipment in our compatibility lab, and test records are kept per batch so that any field question can be traced back quickly.
